Job Description

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.
