Middle Embedded Engineer

We're looking for a 
Middle Embedded Developer
 with strong experience in
RF and network applications. You'll contribute 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 in Lviv 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.
