We are developing quantum processors based on industrial-grade silicon chips, with the potential to radically transform computing power in areas such as materials modelling, medicine, artificial intelligence and more. We have recently moved into a new office in Islington with state of the art cryogenic facilities and have an outstanding interdisciplinary team spanning quantum physics to IC design.Our Team\nSince 2021 our team has been listed every year in the “Top 100 Startups worth watching”in the EE Times, and our technology breakthroughs have been featured in The Telegraph, BBC and the New Statesman. Our founders are internationally renowned researchers from UCL and Oxford University who have pioneered the development of qubits and quantum computing architectures. Our chairman is the co-founder of Cadence and Synopsys, the two leading companies in the area of Electronic Design Automation. We’re backed by a team of top-tier investors including Bosch Ventures, Porsche SE, Sony Innovation Fund, Oxford Sciences Innovations, INKEF Capital and Octopus Ventures, and we have so far raised over £62 million in equity and grant funding.We bring together the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians and software engineers to create a unique, world-leading team, working together closely to maximise our combined expertise. Our collaborative and interdisciplinary culture is an ideal fit for anyone who thrives in a cutting-edge research and development environment focused on tackling big challenges and contributing to the development of scalable quantum computers based on silicon technology.\nOur team of 100+ is based in London, Sydney, San Sebastian & Maryland (US) with a centre of mass in our Islington, London lab.\nFunctions of the Role\nThe primary function of this position will be to undertake CMOS RF IC designs implementing functionalities at the deep-cryogenic temperature regime. In this role you will be part of the IC Design team. The goal of the team is to design circuits that interface with quantum devices. No background in quantum physics is required.This is a rare and exciting opportunity to be an early employee at a start-up shaping the future of quantum computing, and in particular to form a new team within the company. There are vast opportunities for professional growth and to make an impact within the company.\nFunctions of the Role\nArchitecture-level design of low power Tx chain.\nBlock-level schematic design (pre and post layout) of RF Blocks such as LNA, PLL, LO, Mixer, VGA, Filters (depending on experience).\nProvide guidance for the layout of designed blocks and review layout work.\nDocument own work for peer-review and perform design reviews of other team members work.\nSupport the post-silicon validation and characterization of designed RF blocks.\nExperience - Essentials\nExperience in heavy research -oriented environments\nDemonstrated experience of CMOS RF IC design in sub-10GHz frequencies for low power systems.\nIndustry degree qualification and at least 10+ years of work experience in RF IC Circuit Design\nDemonstrated experience in circuit design on or below CMOS 65nm RF processes.\nDemonstrated experience with the Cadence Design environment and SpectreRF.\nSolid understanding of the fundamentals of RF design. Capable of providing feedback on the validity of the working principles of a circuit without the assistance of simulation software.\nUnderstanding of RF testing and demonstrated experience in the application of DFT of RF blocks.\nKnowledge of one or more industry-standard EM simulation toolset (ADS, EMX, CDT, HFSS)\nStrong analytical and problem-solving skills with a high-level of self-management and self-motivation\nExcellent verbal and written communication skills\nExperience - Desirable\nExperience in block-level Layout\nKnowledge of Verilog-A\nDemonstrated experience of MOSFET device modelling frameworks (BSIM preferred)\nProgramming knowledge (Python, SKILL preferably)\nKnowledge of CMOS fabrication technology\nBenefits\nBe part of a creative, world-leading team\nCompetitive salary and share options scheme\nContributory pension scheme\nPrivate Medical Insurance\nLife Assurance\nCycle-to-work Scheme \nFlexible working\nCentral London location\nEEO Statement\nQuantum Motion is committed to providing equal employment opportunity and does not discriminate based on age, sex, sexual orientation, gender identity, race, colour, religion, disability status, marital status, pregnancy, gender reassignment or any other protected characteristics covered by the Equality Act 2010.Internal Job Reference Number\nHRS-81","description_format":"text","description_chars":4733,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Flexible schedule","Health insurance","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-10-01T12:45:06Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.195,"p_room":0.28,"age_days":495,"expected_fill_days":25,"reasons":["conf:12","stale_co","velocity","ghost","win:tail","crowd:"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/quantum-motion-principalstaff-rf-ic-design-engineer","json_url":"https://alion.io/job/quantum-motion-principalstaff-rf-ic-design-engineer.json","meta":{"generated_at":"2026-10-12T14:39:10Z","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":23043,"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":7422},"rest":"https://alion.io/mcp/rest/get_company?id=7422"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fquantum-motion-principalstaff-rf-ic-design-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%2Fquantum-motion-principalstaff-rf-ic-design-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%2Fquantum-motion-principalstaff-rf-ic-design-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/quantum-motion-principalstaff-rf-ic-design-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fquantum-motion-principalstaff-rf-ic-design-engineer"}]}
