Offstream (YC S24) | Senior Software Engineer | San Francisco, CA or Denver, CO (Hybrid, 3 days/week) | $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'd 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: TypeScript, Next.js, GraphQL, PostgreSQL

What we're looking for:

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.

Apply here based on your location:

I'm Zach, Offstream's CTO and co-founder. I personally read every single application that comes through, so don't hesitate to apply even if you're not 100% sure you're a fit
