**About SleepRes** SleepRes is developing next-generation sleep apnea therapy technologies that improve patient outcomes. We are a small, fast-moving R&D team focused on building high-quality medical devices that make a real-world impact. **Position Overview** We are seeking a Lead Mechanical / Pneumatic Engineer to lead the mechanical, pneumatic, thermal, and acoustic development of current and next-generation positive airway pressure (PAP) therapy systems. This is a hands-on technical leadership role where you will own the device mechanical and air-delivery architecture, including blower integration, airpath, enclosure, humidification, breathing-circuit interfaces, thermal performance, and acoustics from concept through commercialization. You will work closely with systems, electrical, firmware, V&V, NPI, quality, regulatory, overseas suppliers, and contract manufacturers to translate product requirements into reliable, manufacturable designs. **Level** This role may be filled at the Staff or Principal level based on experience, technical scope, and demonstrated leadership. • Staff: Typically 8+ years of relevant product-development experience. Serves as the primary technical owner for the mechanical/pneumatic discipline, leads architecture and cross-functional technical decisions, mentors engineers, and remains deeply hands-on in design, testing, and commercialization. • Principal: Typically 10–12+ years of relevant experience with demonstrated platform-level technical leadership. Acts as a company-level authority for mechanical/pneumatic architecture, establishes engineering standards, resolves the most complex multidisciplinary problems, mentors senior engineers, and influences multiple product generations. **What You’ll Do** • Lead mechanical and pneumatic architecture, design, development, and verification for SleepRes PAP products • Own blower integration, airpath, pressure/flow paths, humidifier and water chamber, enclosure, seals, breathing-circuit interfaces, thermal management, and acoustic/vibration performance • Translate system requirements into mechanical and pneumatic specifications, interfaces, and design solutions • Perform and review first-principles analysis including airflow, pressure drop, thermal performance, tolerance stack-up, structural performance, and acoustics • Drive rapid prototyping and product development through EVT, DVT, design freeze, formal V&V, PVT, and commercial production • Lead mechanical design reviews and work with NPI, suppliers, and contract manufacturers on DFM/DFA, tooling, fixtures, assembly processes, and design transfer • Support verification, reliability testing, and root-cause investigations for mechanical, pneumatic, thermal, acoustic, and manufacturing issues • Partner with Operations and Strategic Sourcing on supplier selection, alternate-source qualification, value engineering, and cost reduction • Support design controls and risk management, including requirements, specifications, DFMEA, verification documentation, engineering reports, and design changes • Mentor engineers and help elevate the team's mechanical engineering capability **What We’re Looking For** • BS in Mechanical Engineering or related engineering discipline (MS preferred) • 8+ years of relevant mechanical product-development experience; Principal-level candidates will typically bring 10–12+ years and demonstrated platform-level technical leadership • Strong knowledge of fluid mechanics, pressure/flow systems, thermal engineering, mechanical design, tolerance analysis, injection-molded plastics, seals, and DFM/DFA • Strong CAD capability using SolidWorks, Creo, or a similar professional mechanical-design platform • Demonstrated experience taking complex electromechanical products from concept through commercial production • Hands-on experience with prototyping, engineering characterization, laboratory testing, and multidisciplinary root-cause investigation • Experience working directly with contract manufacturers and component suppliers • Strong systems thinking, communication, and ability to lead technical decisions in a fast-paced cross-functional environment **Nice to Have** • Experience developing CPAP, ventilator, respiratory, anesthesia, oxygen-delivery, or other pneumatic medical devices • Medical-device development experience under ISO 13485 and FDA design controls/QMSR • Familiarity with applicable IEC 60601, ISO 80601, and ISO 18562 requirements • Experience with acoustic engineering, vibration analysis, CFD, FEA, or accelerated reliability testing • Experience with high-volume Asian manufacturing partners and suppliers • Experience leading mechanical engineers or serving as the mechanical technical lead for a multidisciplinary product program
