Neuroelectrics

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 We are looking for a Director of Engineering to own the full engineering function at Neuroelectrics — systems, hardware, firmware, software — and report to the Executive Committee as the senior technical voice in the company. Product decides what we build and for whom; you own how we build it: the architecture, the technical decisions, the engineering quality, and the team that ships it. You combine principal-engineer-level technical depth with proven leadership at scale. You are hands-on by default — when a major signal-integrity issue, a stubborn architectural question, or a release-blocking bug shows up, you do not watch from the sidelines. Systems, hardware and software engineering report to you.  WHAT WILL YOU DO * Contribute to company-level strategy and decisions — from an engineering point of view — and put technical reality on the table when business calls are being made. * Own the full engineering organization — systems, hardware, firmware, software — and the system-level architecture that ties them together. Defend it when reality pushes back. * Own engineering execution end-to-end: architecture, technical design, build quality, V&V, release. Commit to feasibility, technical risk, capacity and schedule with eyes open, so Product can make scope and prioritization calls on solid ground. * Build the engineering team. Hire and retain strong managers and senior Individual Contributors, develop the next layer of technical leaders, and shape an organization that matches where the product is going — not where it has been. * Set the engineering operating system: how we plan, how we review, how we ship. Design and code reviews, configuration management, test automation, release discipline. * Be the senior technical reference on the hardest problems: signal quality, stimulation delivery, connectivity, data integrity, firmware reliability, cloud uptime. You do not debug every issue — but when the team is stuck on something critical, you roll up your sleeves and engage at the same level as your strongest senior engineer. * Own product reliability 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. * Set direction on hardware and firmware: low-noise front-ends, stimulation current sources and safety monitoring, wireless, EMC/ESD, DFM/DFT, production test. You don’t design the next board yourself, but you can challenge the people who do — in detail. * Set direction on software and cloud: device control applications, observability and telemetry, secure update strategy, cybersecurity for connected devices. You can review architectures and code with substance, not just slides. * Work as a peer with Product, RA/QA, Production, Clinical and Customer Support. Bring engineering reality into product and business decisions; once a decision is made, turn it into a rigorous technical plan your team can execute. 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 15+ years) across product and system engineering, including several years at director or head-of-engineering level with managers as direct reports. * Demonstrated track record building and growing engineering organizations: hiring strong people, developing managers, retaining technical talent, and shaping a culture where engineers do their best work. * Technical depth at principal-engineer level, applied at director scope — you own system-level decisions across disciplines and have shipped products that customers depend on. * Medical device experience in regulated environments: design controls, risk management, V&V, and tight collaboration with RA/QA. Familiar with ISO 13485, ISO 14971 and IEC 60601. * Deep electronics background is non-negotiable: analog and mixed-signal design, embedded systems and firmware, wireless, and EMC/ESD considerations. You can read schematics, engage seriously with PCB layout and BOM choices, and challenge designs at the level your hardware leads expect — or above. * Solid software engineering fundamentals — able to review architectures and major design decisions, not just project plans. Comfortable with automated testing and CI/CD as part of how engineering operates. * Structured root-cause and reliability mindset: you build the systems and the team habits that close the loop from field issues to robust fixes. 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 * Background with EEG acquisition systems: biopotential front-ends, electrode interfaces, artifact and noise mitigation. (We work at microvolt scale. You know what that means.) * Background with tDCS/tACS/tRNS stimulators: current source design, compliance voltage, safety monitoring, isolation, stimulation protocols. * Experience leading engineering on cloud-connected medical devices: telemetry, fleet management, remote updates, incident response. * Experience supporting EU MDR and/or FDA submissions — technical files, V&V, audit interactions. * MSc/PhD in Biomedical Engineering, Neuroengineering or a related field. IF YOU JOIN US, YOU WILL ENJOY: Benefits  * Competitive salary in the sector (according to your experience/skills). * 26 vacation days per year + 24th and 31th of December. * Fully stocked kitchen (Coffee, organic fruits, snacks, and beverages). * Flexible Working Hours. * Up to 6 days of working from home per month. * Private Health insurance, including dental coverage. * Professional development and collaborative environment. * Unique opportunity to join our company early with excellent market traction and huge potential to grow * Incredible office in Barcelona in Av. Tibidabo. (shower, stunning views of all of Barcelona, etc.)  * Team Building Events.
