Embedded Software Engineer (LDN)

About This Opportunity

We are representing a confidential mixed-signal semiconductor organization seeking an Embedded Software Engineer for their London office. Our client develops cutting-edge consumer electronics solutions and is looking for an engineer who thrives close to the hardware, building high-performance firmware for DSP architectures and microcontrollers including RISC V and Arm Cortex M/A.

This is a hybrid role requiring two days per week in the London office. You must be based within commutable distance or willing to relocate.

Responsibilities

• Design, implement, and maintain embedded firmware for DSP cores and MCUs (RISC V and/or Arm)
• Build and optimize real-time signal-processing pipelines using fixed-point and/or floating-point arithmetic, including FFTs, filters, codecs, and feature extraction
• Develop firmware using C/C++ and selective assembly with focus on performance, memory, and power optimization
• Work with SoC/board peripherals including DMA, timers, SPI, I²C, UART, I²S/TDM, PWM, GPIO, and relevant bus fabrics
• Bring up new hardware: boot flows, clocks, memory maps, interrupt vectors, peripheral initialization, and early validation
• Implement and debug drivers and RTOS components (e.g., Zephyr or equivalent), including task scheduling, synchronization primitives, and ISR design
• Develop test strategies including unit tests, hardware-in-the-loop tests, test automation, and manufacturing diagnostics
• Use debugging and profiling tools: JTAG/SWD, logic analyzers, oscilloscopes, trace (ETM/ITM), and cycle-accurate profiling
• Collaborate with hardware, FPGA/ASIC, systems, and application teams to define requirements and interfaces
• Contribute technical documentation including architecture notes, interface specifications, timing budgets, and bring-up guides
• Participate in code reviews and establish best practices for embedded quality, safety, and maintainability

What We're Looking For

Required:

• Strong professional experience developing embedded firmware in C/C++ for MCUs and/or DSPs
• Hands-on experience with RISC V and/or Arm architecture (Cortex M/A), including interrupts, memory, caches, and performance characteristics
• Solid understanding of register-level programming, memory-mapped I/O, concurrency (ISRs, RTOS tasks), race conditions, and timing determinism
• Understanding of fixed-point arithmetic, numerical precision, and overflow/underflow management
• Proven ability to optimize firmware through cycle counting, memory layout, DMA usage, cache behavior, and minimizing latency and jitter
• Experience with GCC/LLVM-based toolchains, cross-compilation, CMake/Make, Meson, linker scripts, and map files
• Strong debugging skills with JTAG/SWD debugging and root-cause analysis of timing and performance issues
• Source control expertise (Git) and disciplined engineering practices including code reviews and CI
• Ability to work without requiring an export license (certain embargoed country nationals may be restricted)

Preferred:

• Experience with Python for test tooling and scripts
• Knowledge of DSP cores and RTOS/OS environments like Zephyr or embedded Linux
• Familiarity with GDB, OpenOCD/J-Link, logic analyzers, oscilloscopes, and trace tools
• Experience with profiling, timing analysis, unit/integration testing, and CI/CD for embedded systems
• Knowledge of common DSP libraries (e.g., CMSIS-DSP) and SIMD/vector optimization patterns
• Experience with bootloaders, secure boot, OTA update mechanisms, and field diagnostics
• Understanding of digital communications or audio processing domains
• Exposure to safety/security standards such as MISRA C/C++, IEC 61508, or ISO 26262
