    We are a Britishβ€”Ukrainian air defence tech company building distributed systems across the frontline. We are looking for an experienced Software Engineer specializing in system software development and SDR/RF equipment integration. Your role is to create an architectural β€œbridge” between specialized hardware (SDR via vendor SDK / low-level API, USB/PCIe/Ethernet) and high-level application systems. The main challenge is processing large streams of IQ/spectral data in real-time and building reliable pipelines with minimal latency.

    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 responsibilityβ€”people who execute, deliver, and stand behind the results.

    Key Responsibilities

    • Hardware Abstraction & SDR Integration: Integrate SDR devices via SDK and low-level APIs; manage frequency/bandwidth/sample rate, gain staging, RX/TX streams; work with typical SDR stacks (Aaronia, Harogic, UHD/USRP, SoapySDR, GNU Radio, libiio/LimeSuite or similar).
    • Data Pipeline Development: Design Data Acquisition Layer for IQ streams and derivatives (FFT/spectrum/spectrogram); implement buffering, backpressure/drop policy, (where appropriate) zero-copy; record/replay (IQ + metadata) for debugging and testing.
    • Stream Processing: Primary signal processing (buffering, filtering/aggregation, FFT formation), work with timestamps and metadata (center frequency, gain, sample rate, device time), time synchronization when needed.
    • High-Performance I/O & Networking: Optimized transfer of large data arrays between modules/services; (if needed) IQ streaming over Ethernet/UDP, work with jitter/packet loss, profiling bottlenecks.
    • API & Ecosystem: Develop interfaces for transferring structured information to related teams (Backend/Frontend/Data): spectrum/events/telemetry/config states; API versioning and compatibility with product ecosystem.
    • System Health & Lifecycle: Monitor SDR/hardware state (overrun/underrun, bus/driver errors, temperature; ref/LO lockβ€”if available), logging critical processes, remote diagnostics tools.

    Our Expectations

    • Strong General Software Engineering: Complex system architecture, reliability, testability, performance mindset; understanding of multithreading and parallel computing.
    • Technology Stack: Experience developing in Python and C/C++. Willingness to work with low-level libraries and vendor-specific code.
    • Linux Systems: Deep understanding of Linux: drivers, resource management, udev/permissions, working with USB/PCIe/Ethernet, troubleshooting.
    • High-Performance Networking: Experience with network protocols/transports for large data streams (low latency, high throughput).
    • Engineering Mindset: Ability to quickly dive into SDR/DSP/RF domain at a practical level (IQ/FFT/spectrum, basic radio principles).
    • English level: Intermediate or higher

    Nice to Have

    • Practical experience with Harogic, Aaronia, UHD/USRP, SoapySDR, GNU Radio, libiio/LimeSuite/bladeRF or similar SDR stacks.
    • Understanding of basic DSP principles (IQ, FFT, windowing) and typical artifacts (DC offset, IQ imbalance) at diagnostics level.
    • Experience with time sync / frequency ref (GPSDO, 10 MHz, PPS)β€”if the system uses it.
    • Experience with containerization (Docker) for reproducible environments and deployment.

    We Offer

    • Meaningful, high-impact work in the air defense domain β€” your contributions directly support Ukraine’s air defense.
    • Deep-tech engineering challenges rarely found in the civilian sector, where rigor and performance truly matter.
    • High ownership and autonomy: real influence over technical decisions and the product roadmap from day one.
    • Flexible work format: remote-first with an optional hybrid setup; office visits for team collaboration are welcome but not mandatory.
    • Strong senior engineering team with a culture of clear, direct, senior-to-senior communication and minimal bureaucracy.
    • Office in central Kyiv, available for onsite work when desired.
    • Full-time position with standard business hours; occasional off-hours involvement may be required for testing or critical updates.
