From all manner of backgrounds, our engineers, scientists and ex-military personnel combine their experience to help our customers achieve their true operational potential and ultimately help keep their people and platforms safe. How youll support us Working on-site, embedded within our customer team, you will be offering your expertise on Radio Frequency (RF) modelling and simulation, using ground-breaking science to support the UKs front-line defence. There are two main areas of modelling and analysis which the role will be working on. First, the continued design, development, and operation of software used to verify and validate EW systems across industry partners. The second area of model development and analysis is used to assess novel EW techniques and their effectiveness, with outputs being used to plan future trials. Whilst the two areas specified above will be the immediate priority work, beyond this there are lots of opportunity to be involved in other research, development, testing, analysis, and validation activities across the air platform/mission survivability modelling and simulation domain. This unparalleled access through our customer will help accelerate you as a Subject Matter Expert (SME), allowing you to branch into specialisms as your career progresses. The invaluable experience youll bring, to help us achieve more Working within the Air countermeasure team you will have access to a variety of projects, covering modelling & simulation in software, synthetic, and real-world environments. Your understanding of radar processing, operation, and doctrine will help to generate verified models that inform concept development and assessment. Experience in a related field is valued greatly! Essential: Degree level or equivalent in a Science or Engineering discipline (e.g. Maths, Physics or Engineering). Knowledge of model and simulations techniques to real-world scenarios. Experience in the development of models and tools in order to provide evidence data (MATLAB, Python, or C++).

From all manner of backgrounds, our engineers, scientists, and ex-military personnel combine their experience to help our customers achieve the true operational potential and help keep their people and platforms safe. We are continuing to grow our team at Porton Down, Salisbury, working on key state-of-the-art research, development, and delivery projects, led by our technical customer, Dstl. The primary role is to support testing and optimisation of RF receiver hardware in a new synthetic range (laboratory), with additional support to over-the-air testing (anechoic chamber) and field trials. This will require using a range of RF test equipment to perform digital and analogue injection testing within synthetic EW scenarios. This role will allow autonomy to explore ways to optimise RF receiver performance through configurable memory (mission data) to improve real-world operation of the system when deployed to target platforms. This exploratory process will focus on the increasingly congested and contested electromagnetic environment, developing tactics, techniques, and procedures (TTP) for the RF receiver. To accurately represent the synthetic use cases these systems are required to integrate into, the role will liaise with military, academia, industry and international stakeholders, to complete the validation process. This new lab will be using the latest commercial-off-the-shelf (COTS) development Radio Frequency System on Chip (RFSoC) boards to achieve a high-fidelity electromagnetic environment. You will become and expert in configuring and calibrating these devices to aid testing of the RF receiver systems. This role also has influence over future development work, driving requirements through analysis of current EW systems. As such and understanding of requirements generation and the engineering lifecycle will be valuable to the role. Working autonomously with unprecedented access to the customer,you will be crucial to ensure the success of these key projects, all whilst being supported by our on-site and home-site MASS teams. The invaluable experience youll bring, to help us achieve more. Essential: Ability to work autonomously to optimise complex EW system performance. Understanding of RF sensor systems and Test & Evaluation (T&E) practices. Proficient with RF test equipment (signal generators, oscilloscopes, and spectrum analysers). Experience calibrating hardware and software models into a laboratory environment. STEM Degree or extensive experience with RF Electronics. Desirable: Experience creating scripts/programmes (MATLAB, Python, or similar). Strong background in EW systems and concepts, including radar systems. Experience across the engineering lifecycle (Requirements, V&V, Acceptance). Understanding of Analogue & Digital Signal Processing techniques.
