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 Engineer 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.
