Senior Founding Engineer (San Mateo)
Trayo AI, San Mateo, CA, United States
Senior Founding 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
