We provide some of the world's most advanced quantum control stacks to laboratories and quantum startups across the globe. Our 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. We offer a dynamic environment where engineering meets cutting-edge physics research.\nYour Mission: Architecting at the Edge of Physics and Engineering\nWe need a Software Architect who understands the full stack-from FPGA firmware through embedded systems to high-level Python APIs-and can design the architecture that ties it all together.\nYou will own the technical vision for how our control stack scales from hundreds to thousands of qubits and beyond. This role is both strategic and tactical: you will shape the long-term architectural direction while maintaining a firm understanding of the hardware realities underneath. You are shaping a vision, not micro-managing progress, and we need a leader who makes engineers better, unblocks them, and builds consensus around technical direction.\nRequirements\nKey Responsibilities\nStrategic Architecture\n\nDefine the Control Stack: Design how firmware, embedded software, compilers, and high-level APIs work together as we scale to thousands of qubits.\n\nPlan for Scale: Architect solutions that work today and scale 10x without fundamental rewrites.\n\nEnable Product Vision: Work with product managers and application engineers to translate user needs into architectural decisions that actually work.\n\nCollaborative Direction: Build consensus on abstractions, interfaces, and trade-offs, and convince teams through clarity, not authority.\n\nBridge Teams & Establish Patterns: Connect hardware, firmware, software, product, and application engineering teams around a shared technical vision, defining standards that teams actually want to follow.\n\n2. Tactical Execution\nUnblock Teams: Jump into the hardest technical challenges when teams are stuck, including instruction scheduling bottlenecks, timing constraints, compiler optimization, and distributed control.\n\nDebug Across Layers: Trace issues from Python down through the compiler, firmware, and FPGA when things do not work as expected.\n\nCode When it Helps: Write critical code, prototypes, or proof-of-concepts to validate architectural decisions or show teams the path forward.\n\nGuide, Don't Gatekeep: Review designs with a focus on helping engineers succeed, rather than finding reasons to say no.\n\nListen to Users: Work with customer-facing teams and customers to understand where the architecture is helping or getting in the way.\n\nExperience: 10+ years of software engineering with deep experience across multiple layers of the stack.\n\nEmbedded & FPGA Expertise: Deep embedded systems expertise (hardware interfaces, resource-constrained environments) and a strong understanding of what FPGAs can and cannot do, including timing constraints and firmware/hardware interaction.\n\nSystems Thinking & Performance: A track record of designing architectures that span from low-level hardware to high-level APIs, with experience optimizing for latency, throughput, and determinism.\n\nHands-On Credibility: You still write code when needed and earn respect through technical depth, not title.\n\nCollaborative Mindset: Engineers genuinely enjoy working with you; you make teams more effective and know how to translate perspectives across product, applications, and field teams.\n\nPragmatism: You know when to compromise on purity for shipping, and when to hold the line on fundamentals.\n\nCommunication: Strong ability to explain complex technical decisions clearly to engineers, product managers, and customers.\n\nNice-to-Haves\nDomain Knowledge: A physics, quantum computing, or scientific computing background is nice to have, but not required.\n\nCompiler Experience: Background in compiler design, ASTs, intermediate representations (IRs), or transpilers.\n\nScientific Ecosystem: Experience with quantum or scientific Python software such as Qiskit, Q-CTRL, QUA, Cirq, CUDA-Q, QCoDeS, NumPy, SciPy, xarray, or pytest.\n\nDistributed & Control Systems: Experience with digital signal processing, control systems, or coordinating multiple processors with tight timing requirements.\n\nCustomer-Facing Experience: You have talked to users, understand their pain points, and let that inform your architectural decisions.\n\nWhy Join Qblox?\nImpact: Take on a central architectural role shaping how quantum control software scales globally.\n\nInnovation: Thrive in an interdisciplinary, cutting-edge environment at the intersection of high-level software, low-level firmware, and quantum hardware.\n\nGrowth: Work with a fast-moving, high-performance team building tools used by leading quantum researchers worldwide.\n\nA security screening and reference check may form part of the selection process for this position.\nAcquisition in response to our vacancies by recruitment agencies is not appreciated.","description_format":"text","description_chars":5292,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hardware","Science
