About Symbotic

With its A.I.

-powered robotic technology platform, Symbotic is changing the way consumer goods move through the supply chain. Intelligent software orchestrates advanced robots in a high-density, end-to-end system – reinventing warehouse automation for increased efficiency, speed and flexibility.

Symbotic seeks a highly motivated and hands‑on Senior Mechanical Test Engineer to lead the design, development, and deployment of manufacturing test fixtures for complex electromechanical and robotic systems. This role is responsible for owning fixture development from concept through production deployment, including structural design, actuation systems, integration, validation, and manufacturing support.

• Lead the design and development of mechanical test fixtures for subassemblies and end‑of‑line testing, including structural frames, enclosures, tooling, and mounting systems.
• Create and review detailed 3D CAD models, assemblies, and engineering drawings using Solid Works or equivalent CAD tools.
• Own fixture build, integration, and validation activities including hands‑on assembly, alignment, tolerance verification, and mechanical debugging.
• Design and integrate automated actuation systems including pneumatics, motors, linear actuators, and motion control mechanisms for manufacturing test applications.
• Perform advanced mechanical debugging and root‑cause analysis to resolve fixture failures, reliability issues, and product‑related mechanical problems.
• Collaborate closely with Electrical and Software Engineering teams to integrate sensors, wiring, controls, safety systems, and automation into test fixtures.
• Lead deployment and sustainment efforts at internal manufacturing sites and Contract Manufacturers (CMs), including troubleshooting, issue resolution, and continuous improvements.
• Drive design improvements focused on fixture robustness, repeatability, ergonomics, cycle‑time reduction, manufacturability, and cost optimization.
• Define fixture standards, validation plans, and best practices for scalable manufacturing test platforms.
• Lead technical projects, coordinate timelines, and ensure successful execution from concept through production readiness.
• Mentor junior engineers and technicians by providing technical guidance, design reviews, and debugging support.
• Support new product introduction (NPI) activities and manufacturing ramp efforts.

• B.S. in Mechanical Engineering or related field with 8+ years of hands‑on experience in fixture design, automation systems, or manufacturing engineering.
• Strong proficiency in 3D CAD tools (Solid Works preferred) and creation of detailed engineering drawings and assemblies.
• Extensive experience designing and building mechanical fixtures, automation systems, or manufacturing equipment.
• Strong hands‑on experience with fabrication, machining, assembly, alignment, and mechanical debugging.
• Deep understanding of mechanical systems including tolerancing, GD&T, material selection, structural integrity, vibration, and reliability considerations.
• Experience designing and integrating actuation systems including pneumatics, motors, linear motion systems, and automated mechanisms.
• Strong understanding of manufacturing processes, fixture ergonomics, and design‑for‑manufacturing principles.
• Experience working closely with Electrical and Controls Engineering teams for full system integration.
• Proven experience supporting manufacturing environments and Contract Manufacturers (CMs).
• Proven ability to lead technical projects, manage priorities, and mentor junior engineers.
• Strong communication, organizational, and cross‑functional collaboration skills.

• Experience designing modular and scalable fixture platforms across multiple products or manufacturing lines.
• Familiarity with DFM/DFA (Design for Manufacturing/Assembly) principles.
• Experience working with robotics systems, automated equipment, or electromechanical products.
• Exposure to basic electrical integration including cable routing, connector interfaces, enclosure integration, and sensor mounting.
• Experience improving cycle time, operator ergonomics, reliability, and…
