• Handle the complete circuit design process including component selection, schematic capture, and PCB layout for the Umbrel Home product line • Test and validate all electrical components and systems to ensure quality, reliability and performance, including thermal testing • Ensure all designs comply with industry standards and regulatory requirements • Collaborate with our software engineering team to ensure that the electrical systems integrate seamlessly with umbrelOS • Lead the initial prototyping stages to troubleshoot, iterate, and refine designs • Work closely with our suppliers and manufacturers to prioritize tasks and facilitate the transition from prototyping to mass production • Document the design process and provide technical support throughout the product lifecycle • Identify and implement improvements in electrical design and system efficiency

• Design and implement features end-to-end — from concept to production. • Move fast. We mean it. You're fluent with AI-powered dev tools (Cursor, Claude Code, etc.) and use them to ship at a pace that would be impossible without them. • Own the frontend experience — layout, interaction, motion, polish. • Work directly with engineering and product, iterate in hours not weeks. • Communicate directly. No corporate padding.

• Take ownership of complex frontend features end-to-end - from scoping and architecture to polished, high-quality delivery • Push the boundaries of what’s possible with modern frontend technologies and build pixel-perfect, visually refined UI that matches design specs down to the smallest detail • Collaborate closely with Product, Design, and Backend teams to translate ideas into elegant, performant user interfaces, ensuring a world-class user experience • Maintain high standards for code quality, accessibility, and performance through thoughtful reviews, testing, and best practices • Contribute to evolving our frontend architecture, component library, and design system to support rapid iteration at scale

• Lead design, simulation, tolerancing, and optimization of complex optical systems using tools such as Ansys Optics Studio (Zemax), Code V, LightTools, Lumerical, Quadoa, or equivalent • Perform stray‑light, ray‑trace, wavefront, photon budget, and design for manufacturability (DFM) analyses (e.g., Monte‑Carlo tolerancing) • Translate customer specifications into detailed design requirements; collaborate across mechanical, electrical, firmware/software, and manufacturing teams for system integration and prototyping • Guide validation of designs via lab testing, metrology, and performance measurement (e.g., MTF, distortion, SNR, wavefront) • Mentor and support junior optical engineers and cross‑functional partners, establishing design best practices and documentation • Drive innovation through research into new optical technologies, materials, coatings, and manufacturing techniques, informing future product strategies • Drive critical technical communications / negotiations with customers to ensure optical solutions align with performance, cost, and manufacturability goals.
