Senior Full-Stack Software Engineer

San Francisco, CA · On-site · Full-time
Compensation: $180K–$280K + equity

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.

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

• 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

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

• 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
• Senior compensation plus meaningful early-stage equity

• Location: San Francisco, CA
