Valkyria is a defense-focused software engineering company, built in Ukraine, delivering AI solutions for DefTech companies worldwide. We combine 10+ years of AI engineering expertise with 4+ years of real-world combat testing in Ukraine — covering the full cycle from data collection and annotation to algorithm development, sensor integration and deployment on the edge. Our mission: technology that delivers real advantage on the battlefield, with speed, precision and operational relevance.
About the role: We are looking for an Embedded Software Engineer Consultant to develop firmware and low-level software for defense hardware — unmanned systems, sensors and edge devices operating in harsh and contested environments.
Responsibilities: — Design and develop firmware and embedded software for UAV/UGV, sensor and communication modules. — Integrate sensors, cameras, radios and peripherals (UART, SPI, I2C, CAN, Ethernet). — Develop and optimize software for flight controllers and edge compute platforms. — Deploy and optimize AI/CV models on embedded hardware together with the ML team. — Debug and test on real hardware, including field tests. — Ensure reliability, fault tolerance and resilience under EW conditions.
Requirements: — Hands-on experience in MilTech / Defense projects (e.g., UAV/UGV, ISR, EW, C2, targeting, sensor systems) — required. — 3+ years of experience in embedded software development. — Strong C/C++ skills; experience with RTOS (FreeRTOS, Zephyr or similar) and/or embedded Linux. — Experience with microcontrollers (STM32, ESP32 or similar) and hardware communication protocols. — Ability to read schematics and work with oscilloscopes, logic analyzers and debuggers. — English — Upper-Intermediate or higher.
Nice to have: — Experience with PX4 / ArduPilot, MAVLink, Betaflight / INAV. — Experience with NVIDIA Jetson, Raspberry Pi, Rockchip or other edge AI platforms. — Experience with radio links, video transmission, GNSS or anti-jamming solutions. — Military service background.
What we offer: — Work on mission-critical defense technology with direct impact on Ukraine’s defense capabilities. — Fast feedback loop from real operational use — your work is tested in the field, not just in the lab. — A team that combines strong engineering expertise with real military experience. — Ownership of meaningful technical decisions and room for professional growth. — Competitive compensation, flexible work format.
If this resonates with you, we’ll be glad to connect. Let’s forge victory together!
