Our work focuses on accelerating the deployment of technology, improving decision-making for frontline teams, and protecting people and critical assets in demanding environments.\nHeadquartered in Bristol, Rowden employs around 200 people and operates over 20,000 square feet of engineering and manufacturing facilities. We have a growing international footprint and are one of Europe’s fastest-growing engineering businesses.\nAbout the role\n\nAs part of this journey, we are expanding our RF hardware capability to design and deliver advanced wireless sensing and communication systems across Research and Product.\nThis function designs and delivers RF and mixed-signal hardware platforms that enable sensing, communications, and signal processing in demanding environments. These systems combine analogue RF front-end design, high-speed data conversion, and software-defined radio architectures to create adaptable and high-performance sensing platforms.\nAs a Principal RF Hardware Engineer, you will design and deliver the analogue and mixed-signal hardware that underpins these systems. You will work across the full RF signal chain, from antenna interfaces and RF front-end design through to ADC/DAC integration and SDR platform bring-up.\nThis is a hands-on engineering role working closely with RF, FPGA, embedded software, and machine learning engineers to translate system requirements into robust hardware implementations. You will play a key role in developing RF systems that are reliable, efficient and deployable in complex operational environments.\nWhile this role offers hybrid working options, it requires a minimum of 3 days per week on-site at our Bristol HQ, with occasional travel to customer sites.\nRelocation Assistance: A relocation support package is available for eligible candidates.\n\nCandidates must be eligible for SC clearance.\n\nMore information about security clearance is available here: https://www.gov.uk/government/publications/united-kingdom-security-vetting-clearance-levels","description_format":"text","description_chars":2310,"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":["Hybrid work","Relocation assistance"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Government","National Security","Homeland Security"],"lifecycle":[{"event":"open","at":"2026-09-10T23:41:43Z"}],"visa":[],"liveness":{"score":25,"band":"fade","label":"Fading","p_open":1,"p_active":0.707,"p_room":0.35,"age_days":32,"expected_fill_days":15,"reasons":["conf:0","velocity","win:tail"],"computed_at":"2026-10-12T06:55:09Z"},"pay":{"stated_usd_annual":132470,"is_top_pay":false},"html_url":"https://alion.io/job/rowdentech-principal-rf-hardware-engineer","json_url":"https://alion.io/job/rowdentech-principal-rf-hardware-engineer.json","meta":{"generated_at":"2026-10-12T17:55:44Z","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":28787,"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":685499},"rest":"https://alion.io/mcp/rest/get_company?id=685499"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frowdentech-principal-rf-hardware-engineer"},{"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%2Frowdentech-principal-rf-hardware-engineer"},{"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%2Frowdentech-principal-rf-hardware-engineer"},{"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/rowdentech-principal-rf-hardware-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frowdentech-principal-rf-hardware-engineer"}]}
