San Mateo, CA (Hybrid) / Remote (US-friendly time zones) Full-time #10001

Senior Software Engineer

Early Team / Product Ownership

About Us

We're a fast-moving, VC-backed startup building an AI-powered product for enterprise teams. We work at the intersection of data, automation, and user-facing workflows, helping customers make faster, higher-confidence decisions.

Our founding team brings rare depth across both scale and startup execution:

  • Our CEO previously led multiple large-scale analytics services (hundreds of millions in ARR), owning P&L, product, and GTM, and helped scale a major product from early stage through IPO. Her background spans enterprise software, go-to-market strategy, and AI/ML-driven data platforms.
  • Our CTO is a multi-time founder with successful acquisitions and deep technical leadership experience building developer products and business software used by millions of customers.

Why This Role is Special

This is a true early-stage builder role. You'll be one of the first senior engineers — part of the first generation of engineering in a growing company. You will:

  • Own meaningful product areas end-to-end (design → build → ship → iterate)
  • Influence architecture, standards, and core technical decisions early
  • Work closely with founders and product leadership
  • Ship quickly, with real feedback loops, and build the right foundation as we scale

What You'll Do

  • Build customer-facing product features end-to-end (backend + frontend as needed)
  • Develop AI-enabled workflows and internal tooling that improve product capabilities
  • Design APIs, data models, and services that scale with usage
  • Improve reliability, observability, and performance
  • Contribute to engineering standards (code quality, testing, CI/CD)
  • Collaborate cross-functionally to turn vague problems into shipped product

What We're Looking For

  • 5+ years of professional software engineering experience (or equivalent)
  • Strong backend fundamentals (APIs, databases, services)
  • Product mindset and strong ownership
  • Comfort operating in ambiguity in a fast-moving environment
  • Clear communication and strong collaboration skills

Bonus Points (not required)

  • Startup experience
  • Experience with LLM / AI-enabled systems (retrieval, evals, agent/tool patterns)
  • Strong frontend (React / Next.js)
  • Cloud infrastructure experience (AWS/GCP), monitoring/logging

What We Offer

  • Competitive salary + meaningful equity
  • Small team, high trust, real impact
  • Hybrid flexibility; collaboration hub in San Mateo
