Senior Full-Stack Product Engineer
About Spine
Spine builds integrated security infrastructure for operators of critical infrastructure across Europe — energy grids, rail and logistics networks, data centers, manufacturing sites, and municipal utilities. Our sensor-fused, integrator-ready platform replaces legacy guard-contract security with verified, correlated incidents across a three-layer stack: Sensor (radar, RF, optical, acoustic fused at the edge), Site (an encrypted mesh network that stays autonomous without connectivity), and Portfolio (correlated alerts feeding a Security Operations Center). We're a small, field-oriented team based in Berlin, taking full-stack ownership from embedded firmware to on-site deployment. Our mission: Securing European Prosperity.
About the Role
Spine's core product is the operator-facing console that turns fused sensor data into a live operating picture for security teams protecting critical infrastructure. We're hiring a senior full-stack engineer to own this product end-to-end — from the backend services that ingest and correlate sensor feeds to the real-time web frontend operators watch during active incidents. You'll work with minimal design support, making product calls as you build, and be the person who takes a rough operator need and ships a production feature that holds up in the field on live infrastructure.
What You'll Do
Design and build backend services and APIs (Rust, Python, or Node) that power the operator console
Build and maintain the React/TypeScript frontend used by operators to monitor and respond to live incidents
Implement real-time data delivery via WebSockets/event streams, including live maps and video feeds
Integrate against internal message buses, gRPC/ZMQ-style feeds, and SQL databases
Own features end-to-end: from requirements gathering through design, implementation, and deployment
Collaborate directly with field engineers and customers to understand operator workflows
Contribute to product decisions with minimal design support, exercising strong product judgment
What We're Looking For
5+ years of full-stack engineering experience: backend services/APIs (Rust, Python, or Node) plus modern web frontend (React/TypeScript)
Experience building real-time systems: WebSockets/event streams, live maps, video delivery
A track record of shipping production products end-to-end with minimal design support
Strong product judgment and the ability to make sound calls independently
Comfortable integrating against message buses, gRPC/ZMQ-style feeds, and SQL
Nice to Have
Experience with ops/monitoring/security consoles, or building report/evidence-export features
Compensation & Location
On-site, EU (Berlin)
