We’re looking for a Middle Embedded Developer with strong experience in RF and networks application. You’ll ontribute to radio stack development, participate in real-world field testing, and help shape reliable, scalable communication technology for the next generation of tactical systems. Personal Characteristics * Startup-Agile Minded — Iterates fast, and embraces the mess of early-stage building * Builder First — Codes, prototypes, and ships — leads with hands-on technical execution * Technical Expert — Can project design and guide across embedded, RF, systems integration * Fast Learner — Picks up new tech and domain knowledge fast, without ego * Long-Term Aligned — Invested in the journey, the impact, and the upside — not just the job
Key Responsibilities Architecture & Code Ownership * Design and document scalable, resilient system and infrastructure * Build and evolve the codebase hands-on (C/C++, STM32 embedded stack) * Review developer code, ensure maintainability, and support clean code * Co-Design architecture and write clean scalable code * Be able to find elegant technical solutions
Quality & Testing Oversight * Define and enforce testing protocols for both software and hardware-integrated systems
Field & Integration Involvement * Participate in field testing and real-world validation of systems * Troubleshoot performance issues under real operational constraints (latency, RF noise, etc.)
Tech Experience Embedded Systems & Firmware * 2+ Years — Proficient in C/C++ for bare-metal and RTOS-based systems (FreeRTOS/Azure RTOS, STM32 HAL/LL) * Experience with STM32 microcontrollers * Familiarity with embedded peripherals: SPI, UART, I2C, ADC, DAC, DMA * Experience with interrupt-driven programming and power-sensitive design * Experience in using an oscilloscope, multimeter, logic analyzer
Radio & Networking * Familiarity with radio modulations * Experience with low-level RF link protocols and packet handling * Understanding of signal reliability under interference/jamming conditions is a plus * Select and integrate modulation schemes. * Develop RF coordination between multiple half-duplex transceivers with QoS control. * Validate throughput, latency, jitter, and packet-loss in real-field environments. * Understanding of the network architectures
Architecture & Codebase Management * Architecture planning for embedded integrations * Ability to define modular code structures and hardware abstraction layers
Code & QA Standards * Review and validate developer code * Setup and enforce lightweight QA workflows (unit tests, static analysis) * Drive code documentation, test coverage, and regression tracking
Nice to have Experience * Knowledge of the SDR concept, architecture, hardware and software of modern SDR transmitters and receivers; * Familiarity with video codecs (H.264, H.265, AV1, etc...) * Familiarity with FHSS concepts, best practices * Experience with bootloaders * Experience with SX127x/SX126x/LR11xx/LR20xx * Participate in on-site testing with integrated hardware * Support field troubleshooting: telemetry issues, comms dropouts, thermal behavior, etc. * Experience with FPGA
Who We Are: We’re a deep-tech startup building the next generation of communication systems. Our mission is to combine cutting-edge innovation with user-centred design to deliver reliable, infrastructure-free connectivity — no GPS or fixed networks required. We’ve developed a highly user-friendly LoRa-class link with industry-leading P2P range. Our principle: Resilience over speed — stability and dependability matter more than rushing to market.
What we offer: * Purpose and impact: your work will make a direct contribution to advancing Ukraine’s technology sector. * Stability and transparency: we ensure official employment and on-time salary payments. * Comfort and support: work in a well-equipped office with full technical setup and complimentary daily lunches. * Flexibility and safety: enjoy a flexible schedule and dedicated parking space for every team member.
Join us if you want to work with cutting-edge technologies, take ownership of complex challenges, and see your engineering decisions come to life in real systems. We’re building something that matters — and we’re looking for those ready to build it with us.
