Join a team developing high-performance software for next-generation 5G and satellite communications technology. Working at the intersection of high-performance computing, embedded systems and digital signal processing, you'll help develop and optimise performance-critical software used to run complex 5G physical-layer algorithms on embedded platforms. You'll learn from engineers working on technologies including 5G PHY, O-RAN, FPGA acceleration and real-time embedded systems, while building software where performance, latency and efficient use of compute resources genuinely matter. Key Skills * C or C++ software development * Linux or embedded systems exposure * Interest in performance-critical software * Degree in Computer Science, Engineering, Physics or Mathematics We're not expecting you to be a 5G expert. You may be a recent graduate with a year or two of commercial experience, or someone who has developed relevant skills through an MSc, PhD, placement year or personal projects. Experience with Python, DSP, FPGA technology, multithreading, SIMD optimisation or embedded systems would be beneficial, but isn't essential., * Embedded C/C++ Development * Embedded Software Development * High Performance Computing * Software Engineering Best Practices ## Related Videos - [Unlocking the potential of Digital & IT at Vodafone](https://www.wearedevelopers.com/videos/602-unlocking-the-potential-of-digital-it-at-vodafone) - [Cyber Security: Small, and Large!](https://www.wearedevelopers.com/videos/259-cyber-security-small-and-large) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [When Agents Meet Legacy: Never Change a Running System](https://www.wearedevelopers.com/videos/100320-when-agents-meet-legacy-never-change-a-running-system) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## Related Articles - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Highest Paying Tech Companies in Europe](https://www.wearedevelopers.com/magazine/162-highest-paying-tech-companies-in-europe) - [Software Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/194-software-developer-salary-in-germany-2023) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Software Engineer Salary in The UK](https://www.wearedevelopers.com/magazine/231-software-engineer-salary-in-the-uk)
