We are seeking a skilled and motivated Software Engineer to join our team in the UK. The successful candidate will design and deliver production-quality software that brings advanced RF measurement and optimisation algorithms to life on complex RF hardware. The role focuses on turning RF system and optimisation concepts into robust, deployable software. Working closely with RF and systems engineers, you will implement, validate, and package algorithms in Python, ensuring they perform reliably in real-world, hardware-adjacent environments.

• Tackle complex, open-ended technical problems at the intersection of software, algorithms, and RF hardware, delivering solutions suitable for production use
• Design, develop, and maintain Python-based software used for algorithm development and deployment
• Work closely with RF hardware and systems engineers to ensure strong alignment between software behaviour and real-world hardware
• Integrate, test, and validate software and algorithms on hardware prototypes and production systems
• Apply sound software engineering practices, including modular design, version control, testing, and documentation
• Diagnose, troubleshoot, and resolve software and algorithm performance issues during development and deployment

• Translate algorithm specifications, mathematical models, and experimental insights into efficient, maintainable software implementations
• Own the software realisation of algorithms, from early prototypes through to production-ready modules
• Develop unit tests, validation tools, and reference datasets to verify correctness and support regression testing
• Balance rapid experimentation with the evolution of code into robust, long-lived software

• Support integration with measurement systems, test equipment, and internal tooling as needed for algorithm validation
• Contribute to documentation and technical knowledge-sharing within the engineering team

You're excited by the opportunity to work with breakthrough technologies.

You may thrive in this role if you have some or all of the following:

• Excellent problem-solving and analytical skills
• Ability to translate algorithms, mathematical descriptions, or system requirements into robust, maintainable software
• Demonstrable experience in software development, with strong proficiency in Python for implementing and structuring algorithms
• Experience implementing and adapting algorithms, optimisation methods, or data-driven analysis within real world hardware systems
• Understanding of RF measurements and related test procedures is a strong plus
• Familiarity with test equipment interfacing and communication protocols
• Experience with real time processing is desirable
• Prior experience working with RF modules, wireless systems, or telecommunications is a strong plus
• Bachelor s or Master s degree in Software Engineering, Electrical Engineering, or a related field

• Strong communication and collaboration abilities
• Ability to work independently and as part of a team
• Attention to detail and commitment to producing high-quality software

• Competitive salary and pension contributions
• Company Share Option Scheme
• 25 days holiday + bank holidays
