Basic salary £55k

Hybrid

HQ -Central London

Our client is looking for a pragmatic systems engineer who loves building fast, reliable software that talks to real hardware. You’ll work alongside product designers, embedded/EE, and application developers to ship maintainable, high-performance systems for professional audio.

What you’ll be doing

• Designing and implementing robust, maintainable C++ systems (C++17/20).

• Building efficient, asynchronous services (event loops, concurrency, IPC, networking).

• Managing complex toolchains (cross-compilers, CMake/Bazel), packaging, and versioning workflows (Git, trunk-based or GitFlow).

• Owning CI/CD pipelines and release engineering for smooth delivery.

• Writing rigorous automated tests (unit/integration/functional) with coverage and reliability gates.

• Profiling and debugging in production-like environments (perf, valgrind, ASan/TSan/UBSan, heap/CPU profilers).

• Collaborating tightly with hardware and firmware teams to integrate software with real devices.

What we’d love you to bring:

• Strong background in modern C++ (required): templates, STL, concurrency, RAII, move semantics.

• Solid Linux systems programming: sockets, filesystems, epoll/kqueue, threads, timers, IPC.

• Experience with secure systems design (threat modeling, least privilege, secrets, sandboxing).

• Familiarity with embedded Linux development (Yocto/Buildroot, cross-compilation, init/services).

• Interest in audio software, plug-ins, and AoIP (Audio over IP).

Nice to have

• Rust experience (or a serious interest in learning it); FFI with C/C++.

• Real-time considerations (low-latency I/O paths, jitter budgets, lock-free structures).

• Networking for media: multicast, PTP/IEEE-1588, AES67/RAVENNA/Dante/AVB-TSN.

• Audio domain exposure: plugin formats (VST3/AU/AAX), DSP pipelines, JACK/ALSA/CoreAudio/ASIO.

• Observability/tooling: metrics/logging/tracing, crash capture, OTA/firmware update infrastructure.

• Internal tools and partner portals: small web backends (C++/Rust/Python) to support ops/dev.

What we’re looking for

• Software engineering background (degree or equivalent professional experience).

• Ability to design and deliver well-structured, maintainable systems end-to-end.

• Comfortable collaborating across disciplines with designers, software engineers, and hardware engineers.

• Ownership mindset: you ship, measure, and iterate.

How they work!

• Small, hands-on R&D team; high autonomy, clear accountability.

• Code reviews, automated test gates, and CI as non-negotiables.

• Bias to simplicity, performance, and excellent DX (developer experience).
