Senior Mechanical Engineer

Aescape is a New York-based physical AI and robotics company redefining human recovery through intelligent, precision bodywork, elevating it into a consistent, outcomes-driven practice. Powered by real-time body mapping, advanced robotics, and proprietary software, Aescape delivers deeply personalized bodywork that continuously adapts to the individual. This creates a superior way for members to move with greater ease, recover more efficiently, and optimize how they feel every single day. Aescape is building a defining brand for recovery, shifting behavior from a sporadic experience into a progressive, measurable routine, unlocking compounding benefits that build lasting resilience and laying the groundwork for an entirely new category of proactive human health and performance. Aescape powers recovery across leading fitness, hospitality, and wellness environments, including Equinox, Life Time, Marriott, Hilton, Four Seasons, Pause Studios, and Remedy Place, and is backed by Valor Equity Partners, BroadLight Capital, and Mecha Ventures. Aescape is looking for a Senior Mechanical Engineer to own critical mechanical subsystems on our robotic platform. You will take subsystems from concept through design, analysis, prototyping, and validation, and carry them into production alongside our contract manufacturer and key suppliers. This is a hands-on role on a small, senior hardware team: you will design, build, and test your own work, and stay with it through manufacturing bring-up and into the field. You will work closely with Electrical, Firmware, Controls, Product, and Operations, and you will ship hardware that real people experience with their bodies. If this sounds like you, we'd love to hear from you! For this role, we are open to candidates who can work fully on-site from our NYC office OR those based in the greater Boston area, with the ability to travel to our NYC office regularly. What You’ll Do Subsystem Design & Ownership: Own the design of mechanical subsystems from concept through production release. Balance subsystem-level requirements against system-level constraints, and resolve complex mechanical design issues. Analysis & Validation: Analyze and test your designs using FEA, kinematics, dynamics, and tolerance analysis. Build and test your own prototypes, and drive design decisions from test data and physics. Design for Manufacturing & Cost: Design for manufacturability, reliability, and cost. Select components and processes with an understanding of what they cost at volume, and contribute to cost-down efforts across the product. Manufacturing & Supplier Partnership: Work with our supply chain team, contract manufacturer, and suppliers to develop fixtures and assembly processes, support builds through NPI, and produce the documentation for production transfer: CAD, drawings, BOMs, and specifications. Cross-Functional Partnership: Partner with Electrical, Firmware, Controls, Product, and Operations through the development process, translating requirements into mechanical designs. Issue Resolution & Root Cause: Provide mechanical engineering support for manufacturing and field issues, troubleshoot process and component problems, and drive quality, manufacturing, and material defects to root cause. Invention & Prototyping: Generate new concepts, write invention disclosures, and build rapid prototypes. Travel: As needed for supplier and CM engagements, including international travel. What You’ll Bring Education & Experience: BS/MS in Mechanical Engineering or equivalent experience, with 5+ years of hands-on mechanical design engineering experience on large-scale electromechanical devices. Subsystem Ownership: A track record of owning mechanical subsystems through the full product development lifecycle: design, implementation, debugging, verification, qualification, and transfer to manufacturing. CAD & Analysis Depth: Strong SolidWorks skills, with solid statics, dynamics, kinematics, strength of materials, stress analys
