Traits of a Good Tech Lead

The article distinguishes Tech Lead from Engineering Manager by scope: the EM is responsible for the team across people, product or project, and processes, while the TL is responsible for technical direction across architecture, quality, and mentorship. It also describes common operating models where the roles are split, combined, or left informal.

Reading notes

#

• A Tech Lead owns the team’s technical direction, including key architectural decisions, code and review standards, and helping engineers grow.
• An Engineering Manager owns the team across people, delivery, and process, with the goal of helping the team operate independently.
• The most common operating models are separate EM and TL, the same person doing both, or EM as the only formal role while engineers lead technical initiatives.
• A good TL has a multiplier effect and should not become a bottleneck.
• If the team still depends on the TL for decisions after a reasonable adaptation period, the way of working needs adjustment.
• Good TLs reduce ambiguity, identify risks, simplify open problems, and align technical work with product goals.
• Helpful architecture behaviors include RFCs, small experiments or PoCs, making technical debt explicit, and involving the team in decisions.
• Behaviors that slow architecture down include improvised decisions in chats, endless meetings, prototyping nothing, and one person keeping all technical knowledge.
• Helpful technical-scope behaviors include negotiating the balance between technical debt and delivery, spotting scope creep, and choosing minimum viable technical change.
• Helpful operating-principle behaviors include writing down what the team prioritizes, what it avoids, and what good looks like, then using those principles to make decisions faster.
• When EM and TL are the same person, evaluation gets harder and delegation becomes essential.
• In that case, the article recommends developing champions for areas such as quality, security, and architecture.
• The real measure of TL impact is whether the team depends less on the TL over time.
