Tech Lead

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
