Full Stack Developer

What we’re looking for

We're looking for a highly driven Full Stack Software Engineer to own the software that lets our operators see, plan, and control missions: our Ground Control Station and the broader family of web applications built around it. In this role, you'll work across frontend, backend, and real-time systems, turning live telemetry, mission data, and fleet state into interfaces that are fast, reliable, and trustworthy under field conditions. This is a hands-on, high-ownership role where you'll design, build, and iterate on software operators depend on during real flight tests and missions.

The day-to-day

Ground Control Station: design and build mission planning, live telemetry visualization, and vehicle command interfaces

Real-time pipelines: build low-latency, high-reliability data pipelines connecting the vehicle stack (MAVLink/ROS 2, video/sensor feeds) to the frontend

Backend architecture: architect and maintain backend services, APIs, and databases supporting multiple web apps and real-time streams

Cross-functional collaboration: work closely with autonomy and robotics engineers to define APIs and data contracts between vehicle and ground systems

Reliability engineering: ensure system resilience for degraded-connectivity and field-deployed environments, including offline-first behavior

You should apply if you

Frontend skills: you're proficient in modern JavaScript/TypeScript and a frontend framework, React preferred

Backend skills: you're proficient in a backend language such as Python, Rust, Node.js, or Go

API experience: you've designed and consumed REST/WebSocket/gRPC APIs and worked with real-time or streaming data

Linux comfort: you're comfortable in a Linux environment, including build systems, package management, and networking basics

Engineering mindset: you can take ambiguous requirements and turn them into a working, testable implementation

Education: you hold a degree in computer science or a related field – or equivalent hands-on experience that speaks louder than the diploma, with 2-6 years of experience

Nice to haves

Mapping tools: experience with Mapbox, Cesium, deck.gl, or similar for map-based visualization

Robotics protocols: experience with MAVLink, ROS 2/DDS, or autopilot stacks such as PX4 or ArduPilot

Real-time systems: experience with WebSockets, MQTT, or video streaming such as WebRTC/RTSP

Competitive package: Competitive salary, EGYM Wellpass, corporate benefits, and equity options aligned with role and level.

Deep tech environment: Get hands-on experience with cutting-edge drone technology and real operational use cases.
