About the role
We are looking for a Tech Lead with 4-12 years of experience to step in as a CTO-like leader and run the day-to-day engineering operations at a fast-growing YC W25 voice AI startup. You'll manage a team of 4 engineers, raise the bar across the board, and help double ARR again in H2 — all while working in-person five days a week in San Francisco.
What will you be doing?
-
Manage and lead a team of 4 engineers day-to-day — setting roadmaps, running 1:1s, and owning task prioritization
-
Review code and architectural decisions, ensuring quality standards across speed, performance, and design
-
Establish engineering best practices, processes, and project management cadences
-
Act as a sparring partner to the CEO, CTO, and cross-functional leaders (Sales, CS)
-
Contribute to the codebase yourself (~20-30% of your time)
Key Requirements
-
Formal leadership experience managing a team of 4-10 engineers — not just leading a side project
-
Willing to work in-person 5 days/week in San Francisco (California Street)
-
Strong technical judgment — able to distinguish good code from bad across architecture, performance, and design
-
Highly structured, proactive, and intense — excellent prioritization and project management skills
-
Fluent English with strong communication and executive presence
