If you are interested in learning more about this opportunity, please contact me directly at and send me a copy of your updated resume.

I’d like to share a brief overview of the position:

 Role: Senior Full-Stack Software Engineer

Type: Full-time

Location: San Francisco,CA

We are looking for a Senior Full-Stack Software Engineer with 5+ years of experience to join as a core contributor building a production platform from the ground up at the intersection of process intelligence and agentic AI. You'll be an early engineering hire at a Lightspeed-backed seed-stage company that is already transforming operations for large enterprises.

We need someone who has made architectural decisions, lived with the consequences, and iterated — a builder who writes idiomatic Go, ships React frontends, and has hands-on experience integrating LLMs into production systems. You'll work directly with the founders and have significant technical decision-making authority in a young, clean codebase.

What we're looking for

Must-haves

• 5+ years building production software, with experience shipping across the stack and sustained ownership of meaningful systems.
• Strong backend engineering in a typed language: You have production experience in Go, C++, Java, Scala, or C and can design and operate reliable backend systems.
• Python proficiency: You can build and maintain Python services, work with async patterns, and integrate with AI/ML tooling
• PostgreSQL skills: Database schema design, migrations, and production operations
• React and TypeScript: You can build and maintain a modern React frontend (hooks, context, component composition)
• Hands-on LLM systems design: You have personally built and shipped systems leveraging LLM APIs and understand LLM development patterns (e.g., orchestration, tool calling)
• Pragmatic mindset: You know when to refactor vs. ship, when to build vs. buy, and how to manage technical debt intentionally
• Ownership mentality: You take end-to-end responsibility for features, from design through deployment and monitoring
• Comfort with ambiguity: Early-stage startup means evolving requirements and shifting priorities
