It’s 3:00 AM, production is down, the alerts won’t stop, and management is hovering. Then the Hero logs on. They comb through logs, traverse a maze of legacy spaghetti code, and deploy a patch in half an hour. Slack showers them with praise and the next stand-up celebrates another save. It looks like victory. Look closer and you’ll see failure. Depending on “Hero Engineering” — needing a specific individual to rescue the system through superhuman effort — is a blaring siren that your architecture is broken and your best talent is being squandered.
Your Code is Trying to Tell You Something
If a codebase requires a genius to maintain it, the codebase is the problem. Healthy architecture is characterized by manageability, clear interfaces, and predictability. A competent mid-level engineer should be able to trace data flow and implement fixes without fearing cascading failures.
Reliance on a Hero is a codebase (and organizational) smell that signals something has gone very wrong:
- High Coupling: Everything touches everything else; a tweak in billing knocks out user profiles.
- Low Cohesion: Logic is scattered across giant chains of indirection, producing a mental map only the Hero understands.
- Hidden Complexity: Side effects lurk inside 2,000-line functions.
- Accidental Complexity: Your business domain is actually pretty simple; all the engineering problems are caused by dealing with complicated, inconsistently applied “Enterprise” architecture patterns.
We often talk about the “Bus Factor” as a staffing or HR concern. It’s not. The Bus Factor is a sign of a defective architecture.
In a classic “Big Ball of Mud” codebase, you’ll see hundreds of chaotic dependencies pointing in every direction. By relying on a hero, you are actively introducing one final, invisible dependency: a hard link to the memory of the Hero employee who (currently) works for you.
The Tragedy of the Brilliant Engineer
The saddest part of Hero Engineering isn’t the bad code; it’s the wasted potential. The Hero is almost always your most brilliant engineer. They are the ones with the deepest understanding of computer science, the fastest problem-solving skills, and the highest capacity for abstract thought.
So why are they spending their nights chasing race conditions in five-year-old legacy code?
This is a massive opportunity cost, for both the company and the engineer.
Every hour your best engineer spends grepping logs to patch a fragile system is an hour not spent on:
- Designing the next generation of your platform
- Innovating on new features that drive revenue.
- Mentoring the broader team to raise the bar
You’re forcing your lead architect to work as a janitor because the sewers are constantly backed up. You aren’t just burning them out; you’re locking them into the very system they want to escape. Eventually, they’ll leave for a place where they can build instead of patch.
The Vicious Cycle: Heroes Create Their Own Villains
Sometimes there’s an even darker twist to this sad story: the Hero often creates the technical debt that necessitates their existence. When the system is on fire, they don’t have time to re-architect or decouple — only to hack. Clever bypasses and hardcoded overrides work in the moment, but the sediment piles up.
- A bug appears in complex code.
- The heroic fix arrives via an undocumented patch.
- Complexity rises; the codebase grows more brittle.
- The next bug gets harder, ensuring only the Hero can solve it.
Six months later, the Hero is fighting a fire they unknowingly lit with a previous save. The codebase becomes their stream of consciousness — an alien language to everyone else.
The Solution: Architecture as the Anti-Hero
The goal of engineering leadership should be to make the Hero obsolete, not by adding “agile” process or meetings, but by fixing the code.
I’m not going to go into any detail here since it’s a big subject that I’ve spent most of my career on, but here are a few shallow bullet points:
1. Decouple to Survive
Shift from systems that require “understanding the whole” to systems that require “understanding the interface.” Enforce strict modularity so developers can reason about a single slice at a time. At lower levels, use functional programming so that developers do not trigger side effects that weren’t screamingly obvious. Embrace Event Modeling, and separate the write side from the read side.
2. Refactoring Is Not a Luxury
Reward prevention, not heroics. Refactoring isn’t “nice to have” work for mythical free time; it’s essential maintenance. Budget capacity for paying down architectural debt to the system never needs a caped Hero to save it.
3. Standardize to Survive the AI Era
In the age of AI-generated code, architectural strictness is no longer optional; it is a requirement for survival.
We are entering an era where engineers are generating code faster than ever, and sadly, often with less than their full attention. If your architecture is ad-hoc, inconsistent, full of developer experiments and the remnants of their learning “journey”, AI agents will mimic that mess, generating spaghetti code at an exponential rate.
To prevent a total collapse of code quality, you must enforce rigid standardization and clear templates.
Boring is better: Prioritize readable, standard patterns over brilliant one-liners.
Guardrails: If a junior engineer (or an AI agent) cannot easily discern where logic belongs, your architecture is failing.
Templating: Use strict architectural templates so that generated code falls into pre-defined, safe buckets rather than sprawling across the codebase.
Put the Cape Away
A company that relies on heroes is a company that refuses to fix its foundation. Stop praising the firefighter and start asking why the building is on fire. Free your best engineers from constant repair work. Give them the time and mandate to fix the architecture so they can do what they do best: build the future.
