- Experience writing complex ETL processes for industrial data
What the job involves
- We're looking for a full-time Senior Software Engineer to join us in our mission of bringing the ION Factory OS to next-generation hardware builders around the globe. We are looking for engineers who leverage AI coding tools to build end-to-end features with unprecedented speed and quality
- Our newest recruit will join the First Resonance team full-time in Los Angeles, CA (HQ in El Segundo) as a foundational member of our product team
- End-to-End Feature Ownership: Use AI-augmented workflows (Claude) to build and deploy full-stack features using Python (Backend) and Next.js/TypeScript (Frontend)
- API & Data Architecture: Develop high-performance GraphQL mutations and queries; design relational database models in Postgres that reflect complex industrial processes
- Cloud Infrastructure: Build and maintain scalable services on AWS, leveraging modern infrastructure patterns
- AI-Driven Productivity: Lead the team in adopting AI tools to automate boilerplate, refactor legacy logic, and accelerate the "idea-to-production" cycle
- Technical Leadership: Write design specifications and diagrams (UML/System Flow) that guide both human teammates and AI agents
- Reliability: Drive code-level architecture, modularity, and comprehensive testing (Pytest, Jest) to ensure ion remains mission-critical for our customers
Our take
First Resonance was co-founded by a former SpaceX engineer to offer manufacturers end-to-end software to create any modern hardware, from electric or aerial vehicles to satellites or robotics.
Since founding in 2018, the company has amassed a growing list of extremely impressive customers including satellite manufacturer Astranis, aircraft automation startup Reliable Robotics, and the NYSE-listed Joby Aviation, which intends to operate an air taxi service with its fleet of electric aircraft.
The complexity of the operations that First Resonance’s customers are undertaking speaks to the value of the startup’s OS, especially when it comes to things like part traceability, collaboration, supply chain, and data analytics. The company has secured significant investment, as well as generating impressive interest from the industry, which all suggests it will continue to grow as time goes on.
