Senior Mechanical Engineer

Orion Sleep • San Francisco, CA

11d

About The Position

Orion is building the next generation of intelligent sleep technology—thermal regulation, advanced sensing, and beautifully engineered hardware designed to improve sleep quality and long-term health. We’re ramping toward mass production and scaling globally. Mechanical Engineering is core to how our system functions, feels, and performs night after night. We’re looking for a Senior Mechanical Engineer to own and architect critical mechanical systems across the Orion Sleep System. This role operates at a system level, driving architecture, design quality, manufacturability, and execution from early concept through mass production. You’ll work deeply across thermal systems, fluid routing, enclosures, CMF, mechanisms, and high-precision assemblies, while influencing engineering standards, design direction, and execution velocity. This is a hands-on technical leadership role embedded with Operations, Quality, EE, FW, Reliability, and our global manufacturing partners.

Requirements

• 7–10+ years of mechanical engineering experience in consumer hardware or integrated electromechanical systems
• Proven system-level ownership across complex mechanical architectures
• Deep expertise in plastics, sheet metal, mechanisms, thermal systems, and high-volume manufacturing
• Expert-level CAD proficiency (SolidWorks or equivalent) with strong DFM/DFA and GD&T skills
• Track record of taking products from concept → EVT → DVT → PVT → MP
• Hands-on engineering mindset—comfortable in labs, factories, and design reviews
• Strong technical communication and ability to influence across teams without direct authority

Nice To Haves

• Experience with thermoelectric (TEC/Peltier) systems or thermal-regulation platforms is a plus
• Experience working with Asian contract manufacturers is a plus
• Strong sensitivity to CMF and cosmetic quality standards is a plus

Responsibilities

• Lead design of TEC-based thermal systems, fluid routing, enclosures, and integrated mechanical assemblies across the Orion Sleep System
• Own detailed CAD, tolerancing, GD&T, and stack-up analysis
• Drive CMF alignment, surface quality, and tooling readiness
• Translate system requirements into robust, production-ready mechanical designs
• Work directly with global manufacturing partners across plastics, sheet metal, machining, and final assembly
• Guide tooling development, design changes, and build readiness for EVT / DVT / PVT and MP
• Support on-site factory builds, failure analysis, and process optimization
• Define and execute validation plans for durability, lifecycle reliability, thermal stability, noise, fit, and cosmetic quality
• Partner with Reliability, QA, and Operations to drive root-cause analysis and corrective actions
• Maintain drawings, specifications, ECOs, and build documentation
• Collaborate closely with EE and FW on system integration, routing constraints, and sensor placement
• Partner with Product, Ops, and Supply Chain to balance cost, schedule, and manufacturability
• Lead design reviews and technical trade-offs with clarity and ownership

Benefits

• Mechanical Engineering at Orion is a first-order function. As a Staff Engineer, you’ll help define the technical foundation of a category-defining sleep platform and influence how the product scales globally. Your work will directly impact product performance, customer experience, and long-term platform strategy.
