Middle Embedded Engineer

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.
