Being Employable, Not Impressive

September 22, 2025

Getting a job in coding.

People are good at answering questions.
Language models (ChatGPT) are good at answering them.

These questions are obvious once you’ve seen them, but they may not feel obvious at first.

Natural Order of Questions

How do I get that job? (the anchor)
How fast does a guy get that job?
How long to get that job?
What’s the minimum competence needed to stand out there?
How much/little do you need to know to excel there?
What are the best of the best practices?
Why does that matter?
What’s the highest-tier earner in coding?
Which companies value that most?
How do we screen those companies for fit?
Can we demo that we’re able to think that way and produce code based on that?
Does it help if it looks scientific?
Is it still impressive or is it scary if it seems a bit too scientific — and is impressiveness even the goal, or employability?
AI and startups are all the rage — with billions invested.
Is there a way to position what markets they’re waiting for as broader markets they’re already primed to enter?
Do I even need a GitHub repo at this point?
Would strategies X, Y, Z make sense?
Can I carry over other things from my years of seemingly under-disciplined, under-focused searching into something more marketable?
How much is that worth, in theory?
How much capital would I need to market or license those ideas?
Which of those things is the highest and best use of my time?
Then why the heck would I want to do anything else?

The result:

Potentially, a phone call rather than a GitHub repo, a white paper, or a blog post.

And often enough, at times, some very alien-looking code. The LLM helps determine what the hidden best practices are, searches for the more universal laws of enduring data, highlights what the best quality candidate sources might be, and in a way, encourages a more rigorous co-exploration of what endures.

1. Best Practices for Enduring Code

Simplicity first: Fewer moving parts → fewer failure points. “Readable over clever.”
Test coverage & property-based testing: Don’t just check happy paths — test invariants.
Idempotency & determinism: Code that produces the same result given the same input, even after crashes.
Defensive coding: Clear error handling, retries, graceful degradation.
Versioning & migration discipline: Schema changes, API contracts, backward compatibility.
Observability baked-in: Logs, metrics, tracing — resilience comes from visibility.

2. Why It Matters

Fragile code costs more over time. Resilient code compounds in value.
Employers pay top dollar because downtime, data loss, or outages cost millions.
The “anti-fragile” developer saves their employer future catastrophe. That’s rare, and rare = expensive.

3. Highest-Tier Earners in Coding

Quant finance engineers (trading firms, HFT, hedge funds).
Low-level systems/security engineers (kernel, cryptography, distributed consensus).
Resilience architects (cloud infra, FAANG-level SRE leads).
Specialized niche maintainers (Postgres committers, Rust compiler core team).

We’re talking $500k–$1M+ packages (often total comp, not just base) at the top end.

4. How Fast They Get the Job

If already vetted (GitHub commits, PhD, OSS recognition): weeks.
From zero but with proven sharpness: 2–5 years of visibility and track record.

Speed is proportional to credibility signals.

5. Minimum Competence to Stand Out

Deep comfort with concurrency, distributed systems, networking, cryptography, or low-level performance.
Enough to teach others in interviews.
You don’t need encyclopedic knowledge — just real mastery in one domain and competence across adjacent ones.

6. How Much You Need to Know

To excel: you don’t need breadth everywhere, but you need depth + proof.
Example: writing a fault-tolerant key-value store in Rust, with testing and benchmarks, is enough to stand out — if it’s done with rigor.

7. How Long to Get the Job

Fast-track: 3–5 years if deliberate.
Normal track: 7–10 years in the trenches.
Outlier: someone publishes a breakthrough OSS repo, gets hired instantly.

8. Companies That Value It Most

Trading firms: Jane Street, Citadel, Jump, Two Sigma.
Tech giants: Google, Meta, Amazon, Microsoft, Apple.
Infrastructure firms: Cloudflare, Datadog, HashiCorp, Snowflake.
Security-driven shops: Trail of Bits, NCC Group.

9. Screening Companies for Fit

Look at postmortems: do they publish them? Do they reward engineers who prevent issues?
Check engineering blogs: do they talk about reliability, resilience, and design tradeoffs?
Look at interview loops: are they testing real problem solving vs. pure LeetCode?

10. Why Do Anything Else?

You wouldn’t — unless:
- You want faster short-term money (web freelancing).
- You prefer creative/UX coding over infrastructure.
- You burn out from intensity.

But resilience coding is the prestige path.

11. Demoing the Mindset

Yes — OSS repos, blog posts dissecting resilience, contributing to open protocols.
Show “I think like a systems architect.” That alone is impressive. Yes, impressiveness helps, but durability is what actually retains value over time.

12. Does Scientific Look Help?

Helps in infrastructure and finance.
Hurts in consumer product startups (too ivory tower).
Know the audience.

13. Impressive vs. Employable

Being impressive gets applause.
Being employable gets comp.
Best path: signal practicality and depth. Not abstract proofs, but engineering stories.

14–15. Positioning for AI & Startups

Yes. AI infra (data pipelines, reliability, evaluation frameworks) = broader market already primed.
Don’t pitch “I build alien code.” Pitch “I build robust, tested, scalable systems AI depends on.”

16. Do You Need a GitHub Repo?

Not always. If you have pedigree (FAANG, big-name OSS), no.
If not, a repo/blog is the only portable credibility.

17. Strategies That Make Sense

Reframe resilience as feature velocity enabler.
Pair “boring” reliability with “exciting” AI.
Build small but perfect things, not big fragile demos.

18. Carrying Over Broader Searching

Yes. Cross-disciplinary thinking → creative resilience strategies.
E.g., using thermodynamics metaphors to explain system failure. This is actually marketable storytelling.

19. Worth in Theory

Preventing a $100M outage = millions in salary.
Unique strategies (if licensed) = startup/consulting potential in 8–9 figures, if packaged right.

20. Capital Needed

To market/license: $0–$500k depending on polish.
To productize: seed round ($1–3M) or license through consulting.

21. Highest and Best Use of Time

Build one resilient demo project that showcases thinking.
Write/blog to show strategic clarity.
Target the narrow band of employers that pay for this mindset.

The Punchline

There’s nothing “alien” here. The code looks alien only because most devs never asked the obvious question: What if I optimized for enduring resilience above all else?

That’s not mystical. That’s just discipline + framing + proof of work.

On Being Employable

It is no longer a question of whether one can dazzle. The market has made plain that brilliance, unmoored from discipline, does not pay. What is rewarded instead is employability — the capacity to produce work that does not collapse under the weight of time or scale.

This distinction, while subtle, is decisive. To be impressive is to risk performing for applause, producing code that looks clever but resists maintenance. To be employable is to build with such care and resilience that the work seems unremarkable in the moment, yet becomes indispensable when tested by failure.

The irony, of course, is that a process grounded in restraint and rigorous testing will often appear “alien” or unusually advanced to those who have not walked the same path. It is not alien. It is simply the consequence of asking the obvious questions and answering them in full.

Thus the principle: one does not aim to be impressive. One aims to endure. And if the work, through its clarity and resilience, impresses others, then that is an accident of perception — a byproduct of seriousness of purpose.

On the Top Tier of Coding

At the highest level of the craft, the task is no longer to optimize for speed alone, nor to favor durability at the cost of performance. The work becomes a balancing act — reconciling optimization with durability, and portability with the practical demands of systems that must last longer than the fashions of the tools that built them.

The engineer who commands this balance understands that code must not only run efficiently today, but remain serviceable when tomorrow’s compilers, platforms, or architectures shift beneath it. Optimization without durability is wasted motion; durability without optimization is dead weight. Portability ensures that the investment in thought and testing is not trapped in one narrow domain, but can travel where the market, or the mission, requires.

This is not artistry for its own sake. It is employability in its truest form: the ability to produce work that performs well under pressure, survives the passage of time, and adapts when the environment changes. The outcome may appear extraordinary, even intimidating, to those unaccustomed to its rigor. Yet its essence is neither mysticism nor accident — it is the deliberate pursuit of resilience, carried out with patience and discipline.

At the top tier, then, employability rests not in appearing impressive, but in producing code that will outlast its author.

Finding the Hidden Load-Bearing Beams

Every system, like every building, is held together by elements unseen. On occasion, one can ask after these beams, search for them, and even identify the few that, if shored up, can preserve entire swaths of digital infrastructure. The practice is delicate: backward compatibility is usually treated as sacrosanct, not out of reverence, but because the cost of re-work is high and the risk of breaking production systems is higher still.

Yet best practice also admits the opposite path: the rewrite. Starting fresh, armed with what was learned the first time around, has saved as many systems as careful reinforcement. Both approaches are valid, but they serve different scales and timescales.

In the context of employability, however, a candidate who shows the instinct for finding those hidden load-bearing beams will be recognized as competent and reliable. It signals the kind of judgment that protects systems before they fail. A simple demonstration suffices: a test for drift in a SHA-256 implementation, for example. Checking the least significant bit across runs and architectures is not an optimization tour de force. It does not need to be. It is a small act of resilience — a self-test that can generate heat maps, raise alerts, and point developers toward the first signs of structural strain, whether in data flows or kernel conflicts.

The impression this leaves is not one of ornament or flash, but of seriousness of purpose. It shows that the work is grounded in awareness of what keeps whole systems standing. And for those who hire, that is competence of the highest order.

On Readability and Maintainability

Nested data structures, lambda-style recursion, and bitwise operations only look alien because we’ve trained ourselves not to think like machines. The CPU finds them obvious; only humans call them unreadable. This isn’t a flaw of the constructs themselves, but a reflection of how the industry chose to value speed-to-market and accessibility over low-level alignment. The tradeoff has served us, but it has also left us fragile. Reclaiming even a fraction of that alignment — not as a return to pure machine code, but as a deeper literacy beneath our abstractions — is what turns “alien” into “enduring.”

Why "Alien Code" Cannot Be Truly Unreadable Anymore

It is no longer accurate to call code truly “unreadable” or “unmaintainable.” In the age of AI, the phrase has lost its absoluteness. What once seemed impenetrable — a tangle of nested data structures, lambda reductions, or bitwise shifts — can now be parsed, explained, and reformatted in seconds by a machine that reads fluently at every level of abstraction, without speed-to-market compromises.

This does not mean that discipline is unnecessary. The human reader still benefits from clarity, and the team still bears the responsibility for design choices. But the floor has shifted. What was once condemned as obscure is now at worst inconvenient. Where a developer might once have abandoned a codebase for want of documentation, today the AI can reconstruct intent, highlight the flow, and even propose safer rewrites.

Thus the critique of “unreadable” or “unmaintainable” code is no longer absolute; it is relative to how much effort one is willing to expend. The practical question is not whether the code can be understood, but how costly it is to do so — in machine cycles, in human patience, in organizational will.

In this way, the AI age has stripped the word “unreadable” of its sting. What remains is the older and truer measure: not whether code can be read at all, but whether it was written with resilience enough to endure.

Documentation as the Resolution

The supposed conflict between “highly optimized, low-level code” and “human-readable, maintainable code” is often overstated. In the present era, the tradeoff is not absolute but conditional. It is resolved, in practice, through trusted documentation that makes the step-by-step functionality explicit.

Such documentation does not need to embellish or dilute the underlying logic. It must simply walk through the structure in the order the machine itself executes it: how the data enters, how it is transformed, and how the result emerges. When this is done faithfully, even a dense nest of operations ceases to appear alien. It is revealed as nothing more than a sequence of mechanical steps.

This approach has a second effect: it elevates trust. When documentation is clear, consistent, and verified against actual code paths, the fear of “unmaintainability” recedes. Future developers may not prefer the style, but they will no longer be locked out of its meaning.

Thus the tradeoff is resolved. Optimized code can coexist with durability, provided the written record is as resilient as the code itself.
