Engineering Manager or Tech Lead?

Hiring guidance

Start with the scope

Your choice between a Tech Lead and an Engineering Manager dictates the success of your sprint cycles and long-term product health. A Tech Lead stays anchored in the code. Their primary value is technical decision-making and architecting complex systems. They handle design documents, ensure code quality, and mentor engineers on implementation details. When you need a subject matter expert to force technical alignment, you hire a lead. This person keeps the team moving toward a specific technical vision by working directly in the codebase daily.

An Engineering Manager shifts the focus toward output and personnel. Their role is managing performance, career growth, and the human logistics of your team. They handle conflict resolution, capacity planning, and hiring. While they must understand your technology, they are not your primary technical architect. Their job is ensuring the right person is in the right seat with the right resources. If you focus on individual growth, retention, and department-wide alignment, hire an Engineering Manager. When you conflate these two roles, you end up with either a manager who ignores team performance to code or a lead who loses authority because they are stuck in administrative meetings.

Hiring guidance

Technical Authority Validation

For a Tech Lead, confirm they have designed systems at your scale. Ask for specific trade-offs they made when choosing a database or API structure. An effective lead explains why they rejected a popular framework for a simpler, reliable alternative. A weak candidate repeats marketing jargon about scalability without demonstrating how those choices impacted build times or maintenance costs.

Hiring guidance

Performance Management Documentation

For a manager, review their process for handling underperformers. Ask how they distinguish between a skill gap and a behavioral issue. You want to see a systematic approach that includes clear expectations, regular feedback loops, and actionable improvement plans. Avoid candidates who rely on vague concepts of culture fit rather than concrete performance metrics and measurable goals.

Hiring guidance

Code Ownership Philosophy

A strong lead insists on rigorous code review standards. They do not accept shortcuts. Ask them how they handle technical debt in a fast-moving environment. A reliable lead will provide evidence of how they negotiate with product owners to ensure quality remains high without stalling delivery. Look for their ability to say no to new features that break architectural integrity.

Hiring guidance

Conflict Resolution Tactics

Managers must show they can handle sensitive human conflict. Ask about a time they had to move an engineer off a project or deliver a difficult performance review. You are looking for a candidate who delivers feedback directly and fairly, protecting the team while ensuring individual accountability. They should remain composed and evidence-driven when emotions are high.

Hiring guidance

Evidence to bring into the hiring conversation

Seek Tech Leads in repositories or open-source projects where their code contributions are transparent. Look for evidence of design discussions in pull requests. These candidates are often motivated by the challenge of solving architectural puzzles and are less interested in administrative tasks. They want to be in the weeds of the build process.

Find Engineering Managers by looking for those who have consistently kept teams stable over several years. They are motivated by the craft of building organizations and guiding careers. Their history shows they transition from hands-on work to coaching others effectively. These candidates want to own the delivery process and the human systems that support it.

Hiring guidance

Problems worth catching early

Hiring a Tech Lead to manage administrative tasks, such as compensation reviews or department budgets, which bores them and leads to turnover.

Expecting an Engineering Manager to maintain high-velocity coding output while simultaneously handling deep-dive performance coaching for the entire team.

Failing to define which role has final say on technical debt, which causes the team to move in two different directions during every sprint.

Hiring guidance

Decisions to make before the search

Start by defining your primary pain point. If your code is fragile, seek a lead. If your engineers are unaligned or leaving, seek a manager.

Interview for the primary function only. If you need a lead, drill into their architectural history. Do not waste time asking about their management philosophy.

Evaluate their ability to delegate. A good lead delegates code tasks to grow the team; a good manager delegates technical tasks to prioritize people growth.
