We are a British—Ukrainian air defence tech company building distributed systems across the frontline. We are looking for an Embedded Engineer who will take full ownership of firmware and embedded systems running on edge devices in harsh, real-world environments. You will be responsible for the product’s electronics as a whole and will oversee and control its development.

Our core value is impact for Ukraine: we build technology that makes a real difference on the actual battlefield, not in labs or on paper specs. We operate with a deep-tech mindset, pushing new technologies where engineering rigor truly matters. We value ownership and responsibility—people who execute, deliver, and stand behind the results.

Key Responsibilities
Develop firmware for STM32 (ARM Cortex-M) and ESP32 microcontroller series
Configure and develop Embedded Linux solutions on Raspberry Pi
Integrate different SDR (Software Defined Radio) models into a unified Linux-based ecosystem
Work with vendor SDKs and develop high-performance userspace applications
Work with I2C, SPI, UART, CAN and other protocols
Optimize high-throughput data processing in real time, as well as overall system performance and reliability
Debug inter-process communication, manage buffering and latency
Write supporting software, automation scripts, and monitoring systems in Python
Design architecture for industrial solutions with high fault tolerance; build reliable systems where operational stability is the priority

Requirements

Proven experience in embedded systems and/or Linux systems development
Deep knowledge of C/C++ for microcontrollers and Linux; reliable code that doesn’t crash on the first unexpected packet from hardware
Linux Power User: comfortable in terminal, understands kernel-space vs user-space, knows systemd and driver configuration

Strong Plus
SDR experience: familiarity with RTL-SDR, HackRF, USRP, or GNU Radio
Understanding of data transmission protocols and digital signal processing (DSP)
Experience with defense, dual-use, or other hardware operating in harsh conditions
Hobbies related to electronics, radio communication, or robotics

We Offer
Meaningful and high-impact work in the air defense domain. Your work directly contributes to Ukraine’s air defense
Deep-tech challenges: solve engineering problems that don’t exist in the civilian sector
High ownership: influence technical decisions and the product roadmap from day one
Clear, fast, senior-to-senior communication with a minimum number of team meetings
Standard business hours; some tasks may require involvement outside the usual schedule (testing, critical updates)
Official employment with paid vacation, sick leave, and all statutory benefits
