Senior Technical Project Manager

About the role

Simplexity is a product development engineering firm hired by leading technology companies to design their next-generation products. We are seeking a Senior Technical Project Manager (TPM) with a mechanical engineering or robotics background to drive prototype-build execution on a confidential robotic product-development program at a client site in the Seattle area. You will partner with the program's Lead TPM and own the build schedules: coordinating complex prototype builds across mechanical, electrical, firmware, test, and supplier teams, and driving deliverables to committed dates. This is a hands-on execution role for someone who creates structure in fast-moving, ambiguous environments and isn't shy about pulling people together to make decisions.

Responsibilities

• Own coordination and delivery of current and next-version prototype builds, from design release through fabrication, assembly, integration, and test.
• Build and drive detailed schedules: milestones, dependencies, critical paths, and build-readiness criteria.
• Drive supplier deliverables: set clear dates, interrogate progress, follow up persistently, and escalate risks early.
• Pressure-test engineering and supplier estimates, then push back constructively when timelines aren't credible.
• Proactively convene the right people to resolve ambiguity, unblock execution, and drive decisions to closure.
• Report milestone health, risks, and recovery plans clearly to engineering and program leadership.

Requirements

• BS in Mechanical Engineering, Robotics, Mechatronics, or a closely related engineering field.
• 8+ years of technical project management experience with electromechanical hardware, including direct ownership of complex prototype-build execution.
• Enough engineering depth to evaluate work plans, spot missing dependencies, and judge whether proposed timelines are realistic.
• A track record of creating structure and momentum where responsibilities, priorities, and plans change frequently.
• A proactive, direct facilitation style: you get the right people in the room and
