Team Lead Backend Engineer (Core Applications)

What You’ll Do

• Lead the design and development of APIs that expose GTM data to internal and external users.
• Own end-to-end architecture for large-scale data access patterns, optimizing for performance, cost, and reliability.
• Collaborate closely with AI, data, and frontend teams to ensure seamless integrations and clean API contracts.
• Tackle complex problems like versioning, rate-limiting, auth, query complexity, and cache invalidation across a fast-evolving product surface.
• Build internal tooling to improve engineering velocity and observability for our backend systems.
• Drive engineering best practices, code quality, and testing in a fast-paced, high-output environment.
• Mentor engineers and set the technical direction for the team.

What We’re Looking For

• Ownership-first mindset — you take initiative, move fast, and figure things out.
• Thrive in early-stage, high-urgency environments where speed and impact matter.
• Fully committed to working in-person 5 days/week at our SF HQ.
• Curious, self-aware, and feedback-driven — you bring energy, not ego.
• See this role as a defining chapter — not a stepping stone or side quest.
• 5+ years of backend engineering experience, ideally with exposure to high-scale systems.
• Deep experience with modern backend stacks – Node.js, ClickHouse and AWS.
• Strong understanding of API design principles, query optimization, and distributed systems.
• You’ve worked with large-scale data systems (think TBs of data) and know how to manage performance, cost, and uptime at scale.
• Startup mindset – you move fast, figure things out, and don’t wait to be told what to do.
• Comfortable owning ambiguity – you define the problem, architect the solution, and ship the result.
