We design systems to tackle computational challenges beyond the practical limits of classical machines. Our work sits at the edge of science and engineering. It's complex, demanding, and deeply collaborative. We turn deep research into reliable, full-stack systems that drive discoveries in fields like medicine, energy, and technology, reshaping how the world computes.\nJoin the team that gives quantum a heartbeat.\nThe work\nWe are looking for a Software Engineer to join IQM Numerics team. The key aspect for this role is to work with IQM simulation software tools and develop simulation software further, while actively contributing to planning, critical decisions and peer reviews (code and designs). In this role you will also work closely with Design and Simulations as well as Modeling and Dynamics -teams; initiating and collaborating on requirements setting for simulation interfaces and data compatibility.\nPart of this role is also to collaborate with the external open-source community: follow or respond to community questions and issues, participate in relevant events, e.g. conferences and hackathons, EU projects events and other relevant software as an open-source project.\nWhat you’ll actually do\nSoftware development of the QPU simulation software stack and support the simulations of quantum processing units (QPUs)\n\nDevelopment and maintenance of IQM simulation software tools, including the open-source KQCircuits project and inhouse software\n\nMaintain the development environment, such as CI/CD and the test framework\n\nSupport team members with software development\n\nOrganize and participate in daily/weekly meetings coordinating the backlogs and teamwork\n\nCoordinate an issue-based collaborative workflow within the team\n\nParticipate as software engineer in meetings with other teams/projects when needed\n\nInterface with internal teams on data workflow and the open-source community and external stakeholders\n\nWhat we’re looking for\n3+ years of experience with clear responsibilities in Software Engineering or Software Development\n\nStrong Python skills\n\nExperience in Continuous Integration/Continuous Deployment (CI/CD)\n\nSome understanding or willingness to learn more about quantum physics, QPU simulations and electro-magnetics\n\nCapacity to solve problems and learn continuously independently or collaboratively with other team members while supporting positive team culture\n\nAttention to detail, striving to deliver high quality workflows and improve the simulation processes and tools with each iteration\n\nSupport for an open team culture, where each member assumes shared responsibility, gives and welcomes constructive feedback to improve quality, and responsiveness to problems by solving them together without blame\n\nExperience regarding Artificial Intelligence, Optimization, High Performance Computing languages, such as Fortran or C is seen as a benefit\n\nWhy IQM?\nFull-stack quantum computing: From quantum hardware to software layers and beyond, we build across the full-stack.\n\nHigh-performance playground: We aim high, and we know sustainable performance only works when life outside work does too-hybrid setups, flexible hours.\n\nNever the smartest: You won’t always be the smartest person in the room. Neither will we. Expect to learn constantly - from each other and beyond with IQM’s Learning Hub, LinkedIn Learning, and a team-based L&D budget.\n\nApproachable leadership: Flat hierarchy, direct access. Feel free to approach any leaders. They're friendlier than they look!\n\nThe sweet spot: Big enough to matter. Small enough to move fast. Growing between a startup and a corporation. We’re in the phase where top performers get noticed.\n\nBigger than IQM: Our people build know-how for the entire quantum ecosystem. We publish papers, run hackathons, and help shape a market that's still being defined.\n\nThe future of computing won’t build itself. You might be one of the few who do.\nMeet our people and learn more about IQM on ourstories page.\n\nExplore ourscientific publications.\n\nWe'll start interviews and move forward with hiring as soon as we meet strong candidates. Please submit your application soon.\n600M€+ Total Funding | 400+ Team Members | 30+ Quantum Computers Built | 300+ Patents Filed | 10 Location Globally","description_format":"text","description_chars":4348,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Finland","iso":"FI","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-09-16T22:25:23Z"},{"event":"close","at":"2026-09-23T05:06:12Z"},{"event":"reopen","at":"2026-11-11T14:04:54Z"}],"visa":[],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.555,"p_room":0.35,"age_days":57,"expected_fill_days":25,"reasons":["conf:1","velocity","win:tail"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/iqm-quantum-computers-software-engineer-qpu-numerics","json_url":"https://alion.io/job/iqm-quantum-computers-software-engineer-qpu-numerics.json","meta":{"generated_at":"2026-11-13T15:58:08Z","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":32008,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":1040073},"rest":"https://alion.io/mcp/rest/get_company?id=1040073"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fiqm-quantum-computers-software-engineer-qpu-numerics"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fiqm-quantum-computers-software-engineer-qpu-numerics"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fiqm-quantum-computers-software-engineer-qpu-numerics"},{"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/iqm-quantum-computers-software-engineer-qpu-numerics\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fiqm-quantum-computers-software-engineer-qpu-numerics"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":983193}},{"tool":"search_jobs","arguments":{"company":"iqm.tech","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":983193},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
