CTO versus Tech Lead: at what level should technology decisions be made
In a growing business, the question constantly arises: which technology decisions does the founder or CEO make, which the CTO, which the team Tech Lead. This text walks through decision-level separation, typical mistakes, and the approach to a mature technology organization.
Discuss Your ChallengeAuthorial position: CTO and Tech Lead are not rank levels but different roles with different responsibilities. Without explicit decision-level separation, the company gets either chaos or alignment paralysis.
How this shows up in real life
In a startup or growing company, every technology decision is made by the founder or one strong developer. As growth happens, new roles appear — CTO, team leads, head of engineering — and confusion arises. The team lead makes stack decisions hard to reverse later. The founder intervenes in architectural details of individual modules. The CTO either is buried in code without strategic view, or lives in presentations detached from technical reality. Decisions are made late or, conversely, without due maturity.
Why the bank ended up here
In most growing companies, the technology organization forms ad hoc, without design. First a CTO appears as 'best of the developers', then team leads as 'experienced among juniors', then Head of Engineering as 'organizational CTO'. No one defined in advance which decisions are made at which level. Each new person takes on what they consider important and bumps into a colleague's responsibility area. Conflicts are perceived as personal, though the source is the absence of role architecture.
What teams usually try — and why it does not fix it
- Hire a CTO hoping they will define their role themselves — usually it forms chaotically over 6-12 months
- Make CTO 'first among developers' — without strategic distance, technology vision does not form
- Give team leads full freedom to choose stack — get a technology zoo a year later
- Hire an external architecture consultant — they give an answer, but without internal owner the decision does not stick
- Create an architectural committee — becomes a slow approval body slowing decisions
What type of solution is actually needed
An explicit separation of technology decision levels with role attribution. Company level (main platform choice, cloud attitude, security policy, architectural principles) — CTO or CEO with CTO involvement. Product level (product stack, integration patterns, database choice) — CTO or Head of Engineering with Tech Lead involvement. Module level (individual module architecture, library choice) — Tech Lead. Code level — developer. Each level has its stakeholders for alignment and its review rhythm.
What to check before starting
- Who in the company can say 'no' to a team on choosing a new stack
- Which technology decisions require alignment, which are made autonomously
- How many different stacks and databases are used in the company, and is this diversity justified
- How often a technology decision changes 6-12 months after adoption (sign of wrong decision level)
- Who is responsible for articulating company architectural principles, and do they exist in fixed form at all
How to move step by step
- Articulate company architectural principles — usually 5-10 points on technology, pattern, risk attitude choices
- Define technology decision levels and roles responsible for each level
- Announce these levels and roles publicly within the team — without announcement, no one knows the rules
- Launch a review rhythm — each level has its revision schedule (company — annually, product — semi-annually)
- Give teams autonomy within their level — without autonomy, any hierarchy becomes a brake
- After 6 months — model revision based on real conflicts and decisions
