Senior Software Engineer

Location:

San Francisco, CA or Denver, CO (Hybrid, 3 days/week). Salary: $120k-$190k + equity. Full-time.

Offstream is building the infrastructure for the environmental compliance market, think compliance software meeting real‑world industrial hardware. We’re expanding from pure web application work into physical hardware and real‑world infrastructure, and we need a senior engineer to help drive that.

You’ll be our 5th software engineer, with the opportunity to make a real impact across our entire stack, from data ingestion systems that turn messy real‑world inputs (unstructured PDFs, IoT sensor data) into structured compliance data, to the product surfaces our customers use every day.

Stack:
Type Script, Next.js, GraphQL, PostgreSQL

• 4+ years of software engineering experience, ideally at early–stage startups
• Comfort working with technologies behind real‑world industrial/IoT systems
• Track record building 0-to-1 products or systems
• Genuine enthusiasm for AI‑assisted development (we’re an AI-native team)

If you don’t check every box but think you can grow into this fast, we still want to hear from you. We’re optimizing for high‑slope individuals.
