WHO WE ARE Neuroelectrics is a creative, high-tech company offering the best-in-class non-invasive and high-definition electrical brain stimulation technology for personalized neuromodulation. By measuring and modifying brain function, we aim to restore brain health, minimize disabilities and create a better life for patients. We are looking for new members of our team who already live by our shared values and are inspired by our company's Vision. Accelerate the evolution of brain science and technology by delivering advanced solutions to help end patients suffering from brain pathologies; and our Mission. Revolutionize the understanding of the brain through new personalized neuromodulation therapies, anywhere and at any time. POSITION SUMMARY Most engineering leaders ship features. This one ships technology that interfaces with the human brain — at microvolts of signal and milliamps of stimulation, in homes and hospitals, under the eyes of the FDA and EU Notified Bodies. The margin for error is small. The impact is not. The role, in one paragraph. We are looking for a hands-on technical leader to lead product development engineering at Neuroelectrics and act as the technical bridge between Product and the people who build our medical devices. This is a player–coach role: you set the direction for hardware, firmware, software and cloud — and when a tough signal-integrity issue, a tricky schematic, or a stubborn firmware bug shows up, you are at the bench solving it with the team. You report directly to the Chief Product Officer. We care more about technical depth and hands-on mindset than years of managing. We are open to senior engineers or tech leads stepping into a broader leadership role. WHAT WILL YOU DO * Own system-level architecture across hardware, firmware, software and cloud — and defend it when reality pushes back. * Drive end-to-end execution of new products, components and features from concept to market — making the hard trade-offs between scope, schedule, cost and risk in the open. * Lead root-cause investigations on the hardest issues: signal quality, stimulation delivery, connectivity, data integrity, firmware reliability, cloud uptime. You are the person teams call when the easy hypotheses have run out. * Build engineering excellence that actually moves fast: design and code reviews, configuration management, test automation, release discipline — without ceremony for ceremony’s sake. * Own product reliability end-to-end with Production and Customer Support: triage, complaint trending, corrective actions, reliability programs, and CAPA support when needed. * Drive platform modernization: pay down technical debt, modularize, and plan staged redesigns that lower risk while preserving compliance. * Embed design controls and risk management into how engineering really works day to day; partner with RA/QA to keep traceability audit-ready, not theatrical. * Guide hardware and firmware: low-noise front-ends, stimulation current sources and safety monitoring, wireless, EMC/ESD, DFM/DFT, production test. * Guide software and cloud: robust device control apps, observability and telemetry, secure update strategy, cybersecurity for connected devices. * Grow the engineering organization: hire and retain strong engineers, coach managers and senior ICs, and build a meritocratic culture of ownership. * Run multiple parallel programs with honest visibility on scope, risk, timeline and resourcing. Your first 90 days: So you can picture what "day one" actually looks like. * Weeks 1–2: onboarding. Structured onboarding on our product strategy with the CPO and Product team, and on our quality system, design controls and regulatory processes with RA/QA. By the end of week 2 you have a working understanding of where the product is going and how we are expected to build it. * Weeks 3–4: deep dive. You're in the lab with the hardware team, in code reviews with the firmware and software teams, and in conversations with RA/QA, Production, Clinical and Customer Support. You leave with a clear map of the system, the team, and the top 5 risks. * Weeks 5–8: unblock and ship. You focus on pushing forward projects and investigations that have been stuck or moving too slowly — clearing dependencies, making calls, and giving the team momentum. Concretely, you take ownership of two threads in parallel: one hardcore technical project to resolve an existing problem on the platform, and one more strategic piece of work shaping how we develop a new feature for the market. * Weeks 9–13: bet. shape the roadmap. You translate what you have learned into a concrete engineering plan and feed it into the 3-year company and product roadmap together with the CPO: platform debt to retire, reliability bets, and the 2–3 technical risks you are going to kill before they kill us — sequenced against the product milestones the business is committing to. WHAT DO YOU NEED * BSc/MSc in Electrical/Electronics Engineering, Computer Engineering/Computer Science, Telecommunications, Physics, or a similarly rigorous quantitative field (or equivalent experience). * Significant experience (typically 8+ years) in product/system engineering with demonstrated hands-on contribution across hardware, firmware and software. * Experience leading or coordinating multidisciplinary engineering work. Formal management experience is a plus; we are equally open to strong senior engineers or tech leads ready to step into a broader leadership role with support and room to grow. * Proven track record as a technical reference — owning system-level decisions and shipping products to market. * Medical device experience in regulated environments: design controls, risk management, V&V, and tight collaboration with RA/QA. * Strong background in complex electromechanical/electronic systems: analog and digital design, embedded systems/firmware, wireless. Comfortable reviewing schematics, PCBs and manufacturing/test processes. You are comfortable reading schematics, debugging at the bench with a scope, and engaging seriously with PCB layout, BOM choices, and manufacturing/test processes. * Solid software engineering fundamentals — able to review architectures and code, not just project plans. Familiar with automated testing and CI/CD. * Structured root-cause and reliability mindset: you close the loop from field issues to robust fixes. * Significant experience navigating medical device environments, specifically ISO 13485, ISO 14971, and IEC 60601 YOU WILL BE THE PERFECT FIT IF YOU ARE/HAVE Familiarity expected (or willingness to ramp quickly) * IEC 62304 (medical device software lifecycle) and IEC 62366-1 (usability engineering). * IEC 60601-1-11 (home healthcare environment) for home-use contexts. * Cybersecurity for connected health devices and software (e.g., IEC 81001-5-1 principles). Bonus points * Hands-on with EEG acquisition systems: biopotential front-ends, electrode interfaces, artifact and noise mitigation. (We work at microvolt scale. You know what that means.) * Hands-on with tDCS/tACS/tRNS stimulators: current source design, compliance voltage, safety monitoring, isolation, stimulation protocols. * Cloud-connected medical devices: telemetry, fleet management, remote updates, incident response. * Experience supporting EU MDR and/or FDA submissions (regulatory frameworks) — technical files, V&V, audit interactions. * MSc/PhD in Biomedical Engineering, Neuroengineering or a related field. * How you show up * Hands-on mentality and a real passion for hard technical problems — equally at home in the lab and in the code. * You act (or are ready to grow into) a technical authority and mentor; you raise the bar by doing and unblocking, not only by delegating. * System thinker who connects clinical and user needs to engineering decisions, risk controls and verification strategy. * Communicates complex topics clearly across levels, in writing and in person. * High ownership and urgency, with safety, quality and regulatory compliance as non-negotiables. * Genuine collaborator across Hardware, Software, RA/QA, Production, Customer Support, Clinical and Research. IF YOU JOIN US, YOU WILL ENJOY: Real talk — what this role is NOT * It is not a pure people-management role. If your last few years have been mostly slideware and 1:1s, this will be a stretch. * It is not a greenfield playground. You will inherit a real platform with real users, real history, and real technical debt — and you will enjoy it anyway. * It is not a place to hide behind the process. We respect medical device rigor; we also reject ceremonies that do not make patients safer. * It is not a 100-person mega-engineering empire. We are a focused team where your work shows up in the product within weeks, not quarters. Why this role, why now * Because brain technology is finally graduating from research curiosity into clinically validated, home-deployable medical devices — and the engineering decisions made in the next 12–24 months will define what the next generation of these products looks like. You'd be making those decisions. * Because you will work directly with the Chief Product Officer with a clear seat at the table where product strategy meets technical reality — no telephone game, no proxy. * Because the team is small enough that you matter, and the mission is large enough that it matters back. Benefits: * Competitive salary in the sector (based on your experience/skills) * 26 vacation days per year + December 24th and 31st off * Fully stocked kitchen (coffee, organic fruits, snacks, and beverages) * Flexible working hours and hybrid work model * Private health insurance * Inspiring, purpose-driven team and culture * Beautiful office in Barcelona, located on Av. Tibidabo * Team-building events and professional growth opportunities If this sounds like you: Apply. Send a CV, plus a short note (a paragraph is fine) about a hard technical problem you personally led to ground — what was broken, what you did, and how you knew it was fixed. We read everything that comes in. Not sure you tick every box? Apply anyway. We hire for trajectory as much as for track record.
Join us as a Product Manager to build the accounting products that will make Qonto the default finance workspace for SMEs across Germany and beyond. You'll own our accounting expansion in the German market end-to-end — shaping the product strategy, deepening our local offering, and defining what we build next — in one of the most fragmented and locally complex domains in fintech: German accounting, bookkeeping, and the DATEV ecosystem. You will report to Paul Mourot, Head of Product for Accounting. ➡️ What you'll do Own your product roadmap end-to-end: Define what we build, why, and in what order — working with engineers, designers, and domain experts to ship features that make a real difference for SMEs and their accountants in Germany. Go deep on German accounting workflows and develop a sharp understanding of how accounting actually works in Germany. Define and execute the German accounting strategy by understanding customer needs, evaluating what to build vs. partner on, and shaping an offer that's genuinely useful to German SMEs, not just a localized version of what works elsewhere. Ship faster with AI: Use AI tools (Dust, Notion AI, Claude) and leverage AI as a product lever, identifying where automation and intelligence can transform accounting from a chore into a competitive advantage. Challenge the status quo: Question assumptions, prototype fast, and push for the best possible product. Work with maximum squad autonomy: Your squad owns its roadmap, picks its approaches, and ships independently. No layers of approval, no waiting on committees. ➡️ What we're looking for Deep German accounting domain expertise as you've worked at or closely with a German accounting-tech company. 5+ years as a Product Manager: Concrete examples of products you took from 0 to 1 or significantly scaled. You think in outcomes, not features, and you're comfortable making hard trade-offs. AI-native workflow: You use AI to supercharge how you work — from research and analysis to spec writing and user testing. You see AI as a product lever, not just a productivity hack. German fluency, strong English: You're able to navigate the German market natively — accounting is intensely local, and firsthand understanding of the landscape matters. Strong English is required to work cross-functionally across Qonto's European teams. ➡️ What we can offer you A market being completely transformed: You'll be building Qonto's accounting offer in this market from the ground up and shaping the strategy. Squad autonomy as the default: You own your decisions and ship without red tape. No committees, no approval chains. Unlimited access to the best AI tools: Claude, Dust, Notion AI, Cursor, Copilot — every tool you need, no permission required. ➡️ Your future manager Your manager will be Paul Mourot, Head of Product for Accounting. His path? Paul was CPO and co-founder at Semana (3+ years), Head of Product at BCG Digital Ventures, and CPO at Tiime — an accounting-tech platform — for nearly 4 years. Before that, he led product at AppTurbo, managing a team of designers, data analysts, and POs. He joined Qonto in 2025 to build the accounting product line. He knows the accounting domain from the inside, he's built products for it before. What does he bring to the team? Real ownership for his PMs. You define the vision for your scope and you're accountable for the results. His approach: hire great people, give them context and autonomy, and create an environment where the best ideas win.
