Job description

About the job

Nordic Semiconductor is looking for a Principal Full Stack Engineer to join our Product Engineering team in Boston and step into a key technical leadership role for the “nRF Cloud powered by Memfault” platform. Our platform gives hardware teams the tools to monitor, debug, and update IoT devices in production. Companies like reMarkable, Ultrahuman, and Airthings rely on it to keep millions of devices reliable in the field, and the results speak for themselves. Customers have reported stats like 10x reductions in return rates, 90% fewer device resets, and doubled engineering productivity. We're an industry leader in enabling hardware teams to ship with confidence and iterate fast after launch. Cloud-based tooling and generative AI are changing how products get built, debugged, and shipped. Our platform is at the center of that shift for the IoT industry, bringing software industry best practices to firmware engineers and giving product teams real visibility into how their devices perform in the real world. Customers are onboarding new devices daily, usage is scaling fast, and the developer experience we deliver directly impacts how engineers build connected devices.

Key responsibilities

Lead high-impact initiatives end-to-end, from discovery through architecture, execution, and iteration in production. You own problems, not tickets. Partner with product and design as a peer. Contribute to strategy, challenge assumptions, and shape the roadmap based on deep technical insight and customer empathy. Elevate the developer experience. Think about how firmware developers discover, integrate, debug, monitor, and update their devices, and make every part of that better. Tackle scaling challenges. As adoption grows, design and build systems that perform reliably at scale across both our frontend and backend. Influence technical direction across the organization. Drive architectural decisions, establish patterns, and raise the bar for how the engineering team builds software. Be a force multiplier. Mentor engineers, champion large changes, model technical excellence, and make the people around you more effective. Operate across the full stack. Move fluidly between React/TypeScript frontends, Python backends, cloud infrastructure, and data systems as the work demands.

Qualification and skills

8+ years building and shipping web applications in production, with demonstrated impact at a staff or principal level. Deep expertise across the stack: complex React/TypeScript frontends, scalable Python backends, database tooling (Postgres, Clickhouse) and cloud infrastructure (AWS). Experience influencing technical direction beyond your immediate team, whether through architecture decisions, RFCs, cross-team alignment, or mentorship. Comfort with the full lifecycle. You've operated production systems, debugged incidents, written postmortems, and built observability into what you ship. Nice to Have Experience with IoT platforms, device management, or embedded systems tooling. Background in developer tools, developer experience, or platform engineering. Familiarity with messaging systems or high-throughput data pipelines.

Personal Skills

You lead with ownership. When you see a problem worth solving, you don't wait to be asked. You build the case, rally support, and drive it forward. You're collaborative and humble. You elevate the people around you and believe the best solutions come from working closely with product, design, and engineering peers. You're energized by impact over hierarchy. Title matters less to you than the opportunity to shape a product used by a massive developer community. You have strong opinions, loosely held. You bring conviction to technical discussions but change your mind when presented with better evidence. You're curious about the domain. You want to understand how IoT devices work, what firmware engineers actually need, and how cloud tooling and AI can make hardware product teams fundamentally more effective.
