Our client is a European deep-tech startup developing next-generation radar systems for detecting and tracking small, low-flying drones.
We are looking for a Fullstack Developer with 3–5 years of experience, strong Rust and/or C++ skills, and practical frontend experience. You will build software for radar control, monitoring and real-time visualization, working closely with embedded, signal-processing and AI/ML engineers.
RESPONSIBILITIES
- Develop reliable, high-performance backend services in Rust and/or C++.
- Build interfaces in React and TypeScript for system configuration, monitoring and visualization of detections and tracked objects.
- Connect backend services and frontend applications through WebSocket, REST APIs or gRPC.
- Integrate continuous sensor data streams, telemetry and external systems using TCP/IP, UDP and binary protocols.
- Optimize latency, throughput, memory usage and frontend responsiveness.
- Contribute to modular architecture, automated testing, documentation and Docker-based workflows.
REQUIREMENTS
- 3–5 years of professional software development experience.
- Strong practical knowledge of Rust and/or modern C++.
- Experience with React and TypeScript or comparable frontend technologies.
- Experience with API design, network programming and frontend–backend integration.
- Understanding of asynchronous programming, concurrency and multithreading.
- Experience developing for Linux and working with Git and Docker.
- Strong debugging skills and the ability to work independently in an evolving R&D environment.
NICE TO HAVE
- Experience with radar, robotics, sensor systems or hardware–software integration.
- Familiarity with Tokio, Axum, Boost.Asio, gRPC, Protocol Buffers or ZeroMQ.
- Experience with geospatial interfaces, WebGL/Canvas or Qt/QML.
- Knowledge of profiling, CI/CD, CMake or time-series data storage.
WHAT WE OFFER
Direct ownership of technical decisions and a visible impact on the product. Work with a multidisciplinary R&D team on real-time sensor applications where software performance, reliability and usability matter.
