About the role We are looking for a Staff Engineer to be one of the most senior technical contributors on the engineering team, driving the architecture and execution of the backend systems that power our core product. Since emerging from private beta,the company has seen rapid adoption - hundreds of businesses signing up each week, including larger teams relying on the product in production-critical workflows. The product surface area is expanding quickly: we're building an external API platform, shipping new AI-driven capabilities, and designing the data model and system architecture to support increasingly complex customer workflows. You’ll work primarily in a Postgres-backed, multi-tenant backend (Node/TypeScript on AWS) where API design and data architecture directly shape the product experience. This is not a reliability or platform-focused role - it's a product-facing technical leadership role. You'll be in the room shaping what gets built, then leading the architecture and execution of the most important backend work streams. You'll partner closely with the co-founders and product leadership to translate product ambition into technical strategy, and you'll raise the bar for the engineering team through the quality of your work and your judgment. Scalability and performance are part of the job, but the pitch is the opportunity to shape the product at a foundational level as one of the earliest senior engineers on the team. What you'll do Lead the architecture and execution of the company's most critical backend work streams - API platform, core data model, and systems that underpin new product capabilities Scale our API platform: multi-tenant isolation, versioning, rate limits/quotas, idempotency, and measurable latency/throughput goals Partner with co-founders and product leadership to translate product direction into backend architecture decisions Explore and ship agentic capabilities that require safe sandbox code execution (isolation, resource limits, auditability, security guardrails) Design and ship customer-defined CRM schema (custom fields, custom objects, flexible relationships) without sacrificing query performance or clean APIs Lead complex projects end-to-end - for example, taking custom objects from data model → migrations → query patterns → API ergonomics Own the abstractions that the broader engineering team builds on top of Raise the bar through design leadership, code review, and technical mentorship Contribute to hiring as the team grows - helping identify and close strong technical talent 8+ years of experience of building and scaling backend systems Equity - Meaningful early-stage equity Visa sponsorship available - including new H1B applications applications Hybrid work policy - 4 days in office with Wednesdays being optionally remote. Full-time position Location: San Francisco, CA Tech stack: Node.js, TypeScript, PostgreSQL,AWS
