This is a Staff-level, full-stack Technical Lead role. You'll report directly to the CTO, co‑own the DevEx vision with the PM, and lead a team of five engineers. Your scope is the entire customer‑facing web application suite: analytics, docs, marketing site, sign‑up, and billing. This isn't a feature factory; you'll set the technical architecture, push for full‑stack ownership, and be the catalyst for how AI tools are adopted.
The Work
- Own the end‑to‑end technical vision and architecture for all customer‑facing web applications: analytics dashboard, documentation, marketing site, and billing flows.
- Lead a team of five full‑stack engineers, fostering a culture of rapid iteration and principal ownership over features, not just execution.
- Act as the catalyst for integrating AI tools and LLMs into the team's daily engineering workflow, boosting velocity and judgment.
- Set the bar for code quality, testing, and incident response, while also driving hiring, performance, and career development for your team.
- Collaborate closely with SDK and real‑time infrastructure teams, ensuring a seamless experience from the core platform to the developer's browser.
What You Bring
- You're a strong full‑stack JavaScript engineer (React, TypeScript) with solid backend experience in Ruby on Rails or Node.js.
- A genuine point of view on developer experience, with a track record of shipping solutions for developer or technical personas. You are your own customer.
- Proven experience integrating LLMs and AI tools into engineering workflows to enhance productivity and velocity.
- Prior experience leading a small engineering team, balancing hands‑on technical leadership with people development.
- You thrive in rapid iteration, growth‑stage environments where you co‑create features with PMs and customers.
