Job Description
$120,000 - $00,000 + Equity + Benefits + Relocation Assistance + Flexible PTO
San Francisco, CA - On-site Only (5 days/week)
Are you a backend-focused Software Engineer looking to have real product and infrastructure ownership at an early-stage, high-growth startup? Do you want to design systems that power AI tooling to help American manufacturers win multi-million-dollar federal contracts?
Backed by top-tier investors and led by a technical founding team, this company is modernizing how the U.S. industrial base engages with government defense programs. They've already built strong traction across the national supply chain, with revenues set to surpass 5M ARR in the coming months. Now they're hiring core engineers to help take the platform to scale.
This is an opportunity to work on hard backend problems-think large-scale government data ingestion, parsing messy real-world files (PDFs, Excel, CSVs), and building systems that power critical procurement workflows. You'll be part of a fast-moving, high-ownership team that ships daily and works closely with end users to solve urgent infrastructure and logistics challenges.
You'll primarily work across a modern TypeScript backend stack, building reliable APIs, scalable data pipelines, and infrastructure that supports real-time decision-making. If you have some frontend experience (or want to get closer to it), that's a plus-but this role is focused on system design, backend engineering, and execution speed.
The Role
- Design and build backend services for structured and unstructured data ingestion
- Build and maintain APIs powering frontend experiences and AI tooling
- Develop parsing and automation tools for messy input sources (PDFs, Excel, CSVs)
- Work with queues, caching, retries, and other distributed systems challenges
- Deploy frequently-code, test, ship, and iterate with minimal bureaucracy
- Contribute to infrastructure and ops as needed (the team is small, the impact is large)
- Strong backend engineering experience with TypeScript and Node.js
- Experience designing and scaling distributed systems and internal APIs
- Comfortable working in fast-paced, early-stage environments
- Bonus: some familiarity with React/Next.js or frontend dev
- Open to relocating to or already based in the San Francisco Bay Area
