We do this by providing some of the world's most advanced quantum control stacks to a large range of customers across the globe.\nOur hardware and software sit right next to the quantum chips, giving experimentalists precise control and readout of their qubits. Through our open-source interfaces qblox-scheduler and qblox-instruments, users can write and execute experiments and algorithms using Python - from defining quantum circuits to compiling down to our quantum assembly, Q1ASM.\nWe offer a dynamic environment where engineering meets cutting-edge physics research.\nAbout the role\nWe need a Software Architect who understands the full stack - from FPGA firmware through embedded systems to high-level C++ and Python APIs - and can design the architecture that ties it all together.\nYou'll own the technical vision for how our control stack scales from 100+ to 1,000+ qubits and beyond. This means understanding constraints at every layer: what the FPGAs can do, how firmware schedules instructions with nanosecond precision, how the compiler can optimize quantum circuits, and how users interact with all of it through clean Python interfaces.\nIn this role, you will balance broad strategic vision with tactical technical depth. We need an architect who can design sophisticated, high-level abstractions while understanding the physical constraints of the hardware.\nYou empower teams by providing the architectural guardrails and technical clarity they need to move fast. You measure your success by how much more effective the engineers around you become.\nNote: a physics or quantum computing background is nice to have, but not required.\nWhat you will do\nDefine the control stack architecture: Design how firmware, embedded software, compiler, and high-level APIs work together as we scale to thousands of qubits.\n\nEnable product vision: Work with product managers and application engineers to translate user needs into architectural decisions.\n\nSet technical direction collaboratively: You will shape our core software and interfaces by bringing people along with you. We’re looking for a leader who unifies teams around a shared technical vision, using deep insight and transparent communication to earn trust and drive decisions.\n\nPlan for scale: Design and implement solutions that meet immediate business needs while providing a robust foundation capable of scaling 10x without requiring a fundamental re-architecture.\n\nBridge teams: Connect with hardware, firmware, software, product, and application engineering teams to help create a shared technical vision.\n\nPropose standards: Advocate for developer-centric technical standards that reduce friction and spark efficiency.\n\nGuidance: Act as a trusted mentor and technical advisor, proactively sharing your expertise and guiding teams through complex architectural and design decisions.\n\nClosing the Feedback Loop: Partner with customer-facing teams and engage directly with users to evaluate the real-world impact of our architecture.\n\nRequirements\nEnough about us, what about you?\nTo really succeed in this role, we anticipate you will have a background encompassing:\n10+ years of software engineering with deep experience across multiple layers of the stack. This includes languages such as Python and C/C++.\n\nEngaging Technical Leader: Act as a trusted and highly sought-after collaborator across engineering teams. You cultivate a vibrant technical culture, turning complex architectural debates into energizing, collaborative problem-solving sessions.\n\nEmbedded Systems Mastery: Deep technical proficiency in developing for Linux based resource-constrained environments. You have a proven track record of navigating complex hardware-software interfaces and optimizing for tight memory, power, and processing budgets.\n\nFPGA understanding: You need to understand what FPGAs can and can't do and how firmware interacts with hardware.\n\nSystems Thinking: A proven track record of architecting solutions that maintain structural integrity across the entire stack, from low-level primitives to high-level APIs.\n\nPerformance-minded: Experience optimizing for latency, throughput and determinism.\n\nCross-functional collaboration: You've worked with product, applications, field teams, and know how to translate between different perspectives.\n\nStrong communication: Explain complex technical decisions clearly to engineers, product managers, and customers.\n\nPractitioner-Level Credibility: You are an architect who still speaks the language of the codebase. You build authority through expertise, ensuring your guidance is rooted in the current technical reality of the project.\n\nCustomer-Informed Design: Proven track record of direct user engagement, with a sharp ability to translate customer pain points into robust technical requirements. You seamlessly bridge the gap between user needs and company business objectives to deliver high-impact solutions.\n\nNice-to-haves\nCompiler experience: Background in compiler design, ASTs, intermediate representations (IRs), or transpilers.\n\nDigital signal processing or control systems experience.\n\nQuantum computing knowledge or scientific computing background.\n\nScientific/quantum ecosystem: Experience with quantum or scientific Python software such as Qiskit, Q-CTRL, QUA, Cirq, CUDA-Q, QCoDeS, NumPy, SciPy, xarray, pytest, etc.\n\nDistributed systems: Coordinating multiple processors or hardware units with tight timing requirements.","description_format":"text","description_chars":5559,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hardware","Science & Engineering","Quantum Science & Computing","Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-10-26T03:13:06Z"}],"visa":[],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.389,"p_room":0.28,"age_days":149,"expected_fill_days":37,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/qblox-quantum-system-architect-software","json_url":"https://alion.io/job/qblox-quantum-system-architect-software.json","meta":{"generated_at":"2026-10-31T00:24:04Z","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":607,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":20997},"rest":"https://alion.io/mcp/rest/get_company?id=20997"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fqblox-quantum-system-architect-software"},{"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%2Fqblox-quantum-system-architect-software"},{"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%2Fqblox-quantum-system-architect-software"},{"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/qblox-quantum-system-architect-software\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fqblox-quantum-system-architect-software"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3258413}},{"tool":"search_jobs","arguments":{"company":"qblox.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3258413},"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.
