## About the Role

Software Engineering, Artificial Intelligence (AI), Business-to-Business (B2B), Architectural Services, User Interface Design, Python Programming/Scripting Language, System Operations, User Interface/Experience (UI/UX), Production Systems, System Integration (SI), * 5-10 years of full-stack software engineering experience, with real strength in a typed language (Go preferred), Python, and React/TypeScript

 * A track record of shipping production services with concrete, verifiable contributions across the stack and sustained ownership of meaningful systems
 * Hands-on experience building production systems that integrate with LLMs (real systems, not just prototypes), with a working grasp of patterns like orchestration, tool calling, context management, and evals
 * Solid PostgreSQL depth - schema design, migrations, and production operations
 * Proven experience iterating on features from direct customer feedback, with strong written and verbal communication
 * A pragmatic engineering mindset (knowing when to refactor vs. ship, build vs. buy) and a track record of leading larger, high-impact projects
 * A genuine understanding of what it takes to be a founding engineer in an early-stage environment
 * A BS or higher in Computer Science, Engineering, or a related technical field (a top-30 CS program is a plus, especially earlier in your career)
 * Able to work on-site 5 days a week in San Francisco

Nice to haves

 * Early-stage startup experience, or a mix of big-tech and startup backgrounds
 * Infrastructure-as-Code experience (Terraform, GCP, Docker)

## Description

You'll be a core early engineering hire building a production platform end-to-end. You'll write idiomatic Go, ship a modern React frontend, and design systems that put LLMs to work in production - making architectural calls, living with the results, and iterating based on how things perform in the real world and what customers tell you.

What you'll be doing

 * Own features end-to-end, from design through deployment and monitoring
 * Build and operate reliable backend systems in Go and Python
 * Build and maintain a modern React/TypeScript frontend
 * Design and ship production systems that integrate LLMs (orchestration, tool calling, context management, evals)
 * Work directly with the founding team and iterate on features from direct customer feedback

Tech stack: Go, Python, PostgreSQL, Redis, React 19 + TypeScript, GCP, Terraform, Docker, Datadog, GitHub
