Have experience of developing or integrating HIL or simulation environments within automotive, aerospace, space, robotics, autonomous systems or complex engineering?\nJoin our growing Electronic Warfare Operations Support Group, EWOS, made up of more than 80 specialists, and help us develop a new generation of Hardware-in-the-Loop, simulation and synthetic Test & Evaluation capability.\nThis work contributes directly to the UK Government’s future approach to testing and assuring increasingly complex systems across air, land, maritime and space before they are deployed into operational environments.\nAs the electromagnetic environment becomes increasingly congested and challenging, physical testing alone cannot provide all of the assurance required. We are developing a first-of-its-kind UK capability that combines RF engineering, advanced simulation, synthetic environments and modern verification techniques to recreate complex operational conditions and understand how systems will perform within them.\nYou’ll be joining while this capability is still evolving, giving you the opportunity to influence how it is designed, integrated and delivered rather than simply operating an established test environment.\nThe engineering challenges have strong parallels with work across automotive, aerospace, space, robotics, autonomous systems, telecommunications and other advanced engineering sectors.\nYour experience does not need to have been gained in defence. If you have worked with RF systems, HIL, simulation, test automation or complex systems verification, this is an opportunity to apply that experience to a new and technically demanding problem space.\nYou’ll work from our newly built Lab in St Neots, alongside engineers and technical specialists working across RF, Electronic Warfare, simulation and complex systems engineering.\nHow you’ll support us\nAs our Principal RF Systems Engineer, you’ll lead MASS’s synthetic range activities, supporting both customer and innovation programmes and delivering synthetic Test & Evaluation trials.\nWorking across RF, hardware, software and simulation, you’ll help develop modern approaches to Verification and Validation and apply new technologies and engineering techniques to achieve the levels of assurance required for increasingly complex systems.\nYou’ll provide technical direction to other engineers, act as a key technical point of contact for customers and stakeholders and help shape how the capability develops as new requirements, technologies and engineering challenges emerge.\nYou’ll also have the scope to bring ideas and approaches from your own engineering background, helping us identify where techniques already proven in other sectors can improve the way complex systems are tested and assured.\nThe invaluable experience you’ll bring, to help us achieve more\nWe’re looking for someone with strong practical experience of RF, simulation, HIL or complex test environments who is comfortable working across multiple engineering disciplines.\nEssential experience\nExerience creating test scripts, programmes or suites using tools such as LabVIEW, Python or MATLAB for Test Bench Equipment, HIL environments or bespoke hardware.\nExperience of synthetic hardware, simulation or testing methods, such as DSI and IQ streaming.\nExperience using laboratory equipment including Network Analysers, Signal Generators and Oscilloscopes.\nExperience carrying out calibration and configuration activities against defined test strategies.\nSTEM degree or equivalent relevant experience.\nDesirable experience\nKnowledge of RF, radar, communications, sensing or Electronic Warfare systems.\nExperience working on physical, synthetic or virtual trials.\nExperience using version control software such as Git.\nExperience using network analysis tools such as Wireshark or SolarWinds TFTP.\nExperience of analogue circuit design and build within low-power laboratory environments, such as Up/Down Conversion.\nExperience mentoring or coaching other engineers.\nExperience working within agile engineering projects.\nOur non-negotiables:\nDue to the highly secure nature of the projects that you will be involved with, you must be:\nA UK National / eligible to work in the UK\n Eligible to obtain and maintain a UK Government Security Check (SC) / Developed Vetting (DV)-level security clearance (Gov.uk guidance)\nWho is MASS?\nMASS is an independent, global technology company, trusted by highly-secure organisations to provide advanced, digital services that manage data and keep information safe. With our heritage in defence, we offer robust solutions to sectors where security expertise is essential.\nWe work in partnership with customers, using skilled, technical experts. We think innovatively to provide tailored, agile and resilient solutions that secure advantage, so you’re ready for digital transformation. MASS is an equal opportunities employer; we know that our people are smart, skilled and motivated and in return we provide a friendly workplace where everyone is valued and has the chance to make an impact.\nApply today to see how working for MASS could work for you!","description_format":"text","description_chars":5576,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Dental insurance","Professional development"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-09T00:39:38Z"}],"visa":[],"liveness":{"score":59,"band":"ok","label":"Likely open","p_open":1,"p_active":0.781,"p_room":0.75,"age_days":19,"expected_fill_days":23,"reasons":["conf:2","velocity","win:late"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/mass-principal-rf-systems-engineer-hil-simulation","json_url":"https://alion.io/job/mass-principal-rf-systems-engineer-hil-simulation.json","meta":{"generated_at":"2026-10-12T18:21:21Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":29637,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":4372552},"rest":"https://alion.io/mcp/rest/get_company?id=4372552"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmass-principal-rf-systems-engineer-hil-simulation"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fmass-principal-rf-systems-engineer-hil-simulation"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fmass-principal-rf-systems-engineer-hil-simulation"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/mass-principal-rf-systems-engineer-hil-simulation\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmass-principal-rf-systems-engineer-hil-simulation"}]}
