About the company

Our client is a seed-stage enterprise-AI company building a platform that captures the operational knowledge generated inside the world’s largest organizations and turns it into a living specification that agentic systems can operate from — working at the intersection of process intelligence and agentic AI. Just months in, they’re already transforming operations for large enterprises, and they’re backed by a top-tier venture firm. This is a chance to be one of the first engineers on a young, clean codebase with real technical ownership.

AI, Enterprise, B2B

The role

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

Requirements

• 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)

Why join

• Get in early on a category-defining product at the intersection of process intelligence and agentic AI
• Real technical ownership across the full stack in a young, clean codebase
• Work directly with a founding team that’s already in market with large enterprises
