The fundamental business purpose of engineering is not the act of writing code, but applying technical skills to achieve concrete financial outcomes. All engineering work ultimately serves one of these two goals: increasing revenue or reducing costs.

A senior engineer's greatest impact often comes not from being the deepest technical expert, but from having enough context across multiple domains (marketing, PR, engineering) to act as a translator. They synthesize information and help teams with deep expertise navigate complex, cross-functional decisions.

When hiring senior engineers, the crucial test is whether they can build. This means assessing their ability to take a real-world business problem—like designing a warehouse system—and translate it into a tangible technical solution. This skill separates true builders from theoretical programmers.

When hiring senior technical talent, the most valuable skill isn't just coding proficiency but the ability to take an abstract business problem—like designing a logistics system—and translate it into a functional technical solution. This skill demonstrates a deeper understanding that connects work to real-world value.

With AI agents automating raw code generation, an engineer's role is evolving beyond pure implementation. To stay valuable, engineers must now cultivate a deep understanding of business context and product taste to know *what* to build and *why*, not just *how*.

Engineers must resist the urge to strive for technical perfection. The optimal solution is one that fits the current business context, whether that's preparing for a funding round, an acquisition, or a commercial launch. Knowing when 'good enough' is sufficient is a critical business skill.

To get product management buy-in for technical initiatives like refactoring or scaling, engineering leadership is responsible for translating the work into clear business or customer value. Instead of just stating the technical need, explain how it enables faster feature development or access to a larger customer base.

To prevent engineers from focusing internally on technical purity (e.g., unnecessary refactoring), leaders must consistently frame all work in terms of its value to the customer. Even tech debt should be justified by its external impact, such as improving security or enabling future features.

Technical executives often fail in interviews with PE firms because they can't articulate the business value of their work. Candidates must prepare to speak like they're in a board meeting, clearly connecting their initiatives to measurable outcomes like cost savings, revenue lift, or efficiency gains.
