We do this with our unique VIO™ technology, the only QPU architecture that breaks the hardware barriers that have held quantum computing back, unlocking the path to MegaQubit quantum processors.\nWith VIO, we are paving the way for the hyper-scale quantum computers that will change the world. And delivering on that vision demands people who don’t shy away from tackling the hardest challenges of our time. That’s where you come in!\nAs a Quantum R&D Engineer - TWPA Design, you will act as a domain expert on the physics and architecture of our Josephson Travelling Wave Parametric Amplifiers and will translate product specifications into TWPA architectures. You will focus on pushing the fundamental limits of our microwave engineering, solving complex simulation-to-fabrication mismatches, and spearheading the integration of advanced on-chip components.\nWhat you'll be doing\nTranslate product specifications & features into TWPA layouts and circuit designs through simulations.\n\nDrive the miniaturisation of our TWPA architectures and successfully design and integrate critical peripheral components on-chip\n\nResearch directions include extending bandwidth, improving noise performance, and integration of peripheral functions like pump coupling and isolation.\n\nPresent findings and technical proposals clearly to both technical and non-technical stakeholders, influencing roadmap and product decisions.\n\nStay informed of relevant literature and state-of-the-art techniques in parametric amplification, actively contributing new ideas and approaches to the team.\n\nYour Profile\nPhD or equivalent industry experience in quantum-limited amplification, parametric amplifiers (e.g. TWPAs, JPAs), or closely related superconducting microwave circuits.\n\nDeep expertise in non-linear metamaterials, Josephson circuits, and mixing processes.\n\n>3 years of hands-on experience with advanced microwave design and simulation (e.g., CST, HFSS) with a proven track record of matching simulations to cryogenic measurement data.\n\nTrack record of independent, creative problem-solving in a research and development setting.\n\nExcellent communication skills, with the ability to clearly present technical findings and influence decisions across disciplines.\n\nPassionate about qubit readout amplification; pushing amplifier performance to the physical limits and thrive in a fast R&D environment.\n\nDon't tick every box? Apply anyway! Research shows women often self-select out if they don't meet every requirement. Here's our take: nobody ticks every box. This is a description of our ideal candidate, not a filter. If most resonates and you're keen to learn the gaps, apply. We hire for trajectory, not perfection.\nWhat We Offer:\nAt QuantWare, you’ll be part of a high-performing team of world-class experts in an ambitious, fast-moving environment. From day one, you’ll have the trust, tools, and support to do your best work. Here’s what you can expect:\nCompetitive salary - A salary that reflects the impact and importance of the role (and of course 8% holiday allowance)\nPension that’s built to last - A generous and future-proof pension plan that includes partner and dependent coverage.\nFlexibility built on trust - We focus on outcomes. Work flexibly, in a hybrid setup, with an open vacation policy that lets you manage your time\nPersonal growth - We invest in your L&D, with a budget available to each team member, dependent on their individual ambitions, development needs, and performance\nA connected team - We make space to celebrate wins together, with team events, offsites, and spontaneous moments that bring us closer\nDiversity & Inclusion at QuantWare\nWe’re an ambitious company, not only for our goals but also to become an even more diverse and inclusive team. We know great candidates don't always follow a straight path, and we value diverse experience, perspectives, and ways of thinking. We know this helps us make better decisions, drives more innovation, and strengthens our culture. \nAs part of our recruitment process, candidates may be required to undergo pre-employment screening.","description_format":"text","description_chars":4210,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Netherlands","iso":"NL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-09-06T17:57:22Z"}],"visa":[{"country":"NL","licensed_sponsor":true,"evidence":"Recognised sponsor of the Dutch immigration service (IND)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Highly skilled migrants and regular labour","cap_exempt":false,"checked_at":"2026-10-03T21:10:06+00:00","sources":["IND: public register of recognised sponsors (work)"],"filings_for_role_12m":0}],"liveness":{"score":14,"band":"cold","label":"Long shot","p_open":1,"p_active":0.486,"p_room":0.28,"age_days":77,"expected_fill_days":28,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-15T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/quantware-quantum-rd-engineer-twpa","json_url":"https://alion.io/job/quantware-quantum-rd-engineer-twpa.json","meta":{"generated_at":"2026-10-15T18:01:32Z","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":27277,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":15375},"rest":"https://alion.io/mcp/rest/get_company?id=15375"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fquantware-quantum-rd-engineer-twpa"},{"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%2Fquantware-quantum-rd-engineer-twpa"},{"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%2Fquantware-quantum-rd-engineer-twpa"},{"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/quantware-quantum-rd-engineer-twpa\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fquantware-quantum-rd-engineer-twpa"}]}
