AccelerComm, a University of Southampton spinout, develops error correction and physical layer IP for 5G, 6G and satellite networks, running on more than 200 satellites. They're hiring a Software Engineer to optimise platform code for its 5G NR physical layer on embedded hardware, based in Southampton on a hybrid basis. This software engineering role sits within the UK's semiconductor and satellite communications sector.
We are seeking a Software Engineer to help implement, design and optimize the infrastructure code underpinning our 5G NR physical layer (PHY) systems. This role focuses on developing and optimizing platform specific code to ensure real-time performance on embedded platforms
Key Responsibilities
Platform Development
- Develop software for running and testing the 5G NR PHY algorithms
Performance Optimisation
- Utilise SIMD, multi-threading, and hardware acceleration (e.g., FPGA, DSP).
Integration & Testing
- Integrate the platform code with 5G NR PHY algorithms and ARM enabled boards.
- Improve and maintain CI testing across the entire platform
Standards Compliance
- Support interoperability testing with other vendors and operators.
Collaboration
- Work closely with system-test, hardware, and system architecture teams.
- Customer facing experience.
- Contribute to technical reviews.
Skills, Knowledge & Expertise
Required Skills
- Strong proficiency in C or C++
- Proficiency in a scripting language: Python, Groovy, bash
Preferred Skills
- Experience with real-time embedded systems and Linux.
- Familiarity with hardware acceleration (FPGA, DSP, SIMD).
- Knowledge of signal processing and optimisation techniques.
- Hands-on with FPGA toolchains (Xilinx Vivado).
- Exposure to O-RAN architecture and fronthaul protocols (eCPRI).
About AccelerComm
AccelerComm is a Southampton-based semiconductor IP company spun out of the University of Southampton's Electronics and Computer Science department in 2016 by Professor Rob Maunder and Dr Taihai Chen. The company commercialises forward error correction and channel coding algorithms for 5G, 6G, and satellite non-terrestrial networks, with products including high-performance LDPC and POLAR error correction IP. AccelerComm's technology powers over 200 production satellites currently in orbit, with customers including Vodafone, Intel, AMD, and National Instruments. The company raised a total of $52.8M, including a £21.5M Series B in 2023 led by ParkWalk, SwisscomVentures, and Hostplus, and a subsequent $15M round in 2025.
