Senior Mechanical Engineer

Overview

Senior / Staff Mechanical Engineer – Mechanisms (Individual Contributor)

Venture-Funded Physical AI Robotics Company (Stealth Mode)

We’re conducting a retained search for a stealth-mode Physical AI robotics company building

mission-critical autonomous electromechanical systems .

This is a

hands-on, senior individual contributor role (Senior / Staff level) . You will

own the design and architecture of complex mechanisms

from concept through production. You will not manage a team - you

own the technical decisions that define product performance, reliability, and manufacturability.

If your expertise lies in

designing high-precision, high-speed mechanisms , solving challenging kinematic and electromechanical integration problems, and making trade-offs where performance, repeatability, and manufacturability collide, this role is intentionally demanding.

Founder-Led, Operator-Driven

You’ll work directly with two hands-on founders who bring unmatched technical and operational credibility :

Acting CTO (Product & Technology)

Owns all product and technology, from mechanical architecture through production deployment

Builds and optimizes mechanical systems, embedded integration, and electromechanical platforms

Senior engineering leader shaped by Tesla-scale manufacturing and Zipline-scale autonomous systems

Drives first-principles thinking, rigorous testing, and mechanisms that survive field deployment

The Role

As

Senior / Staff Mechanical Engineer - Mechanisms , you will

lead the design and optimization of complex electromechanical systems

for a revolutionary autonomous robotic platform. Your work will directly impact mechanism performance, repeatability, reliability, and scalability.

You will : Architect and design

high-speed, high-precision mechanisms

for autonomous medication handling

Solve complex kinematic challenges, ensuring repeatable motion under tight tolerances

Integrate mechanical systems seamlessly with actuation, sensing, embedded control, and software

Drive DFM strategy and scale designs from prototype to high-volume production

Establish robust test, validation, and reliability protocols for mission-critical operations

This is

ground-up product building : design, prototype, test, refine, document, and see your mechanisms deployed at scale.

What You’ll Build & Lead

Advanced Mechanisms :

High-speed, high-accuracy dispensing mechanisms capable of handling hundreds of unique items

Precision linkages, cams, gear trains, and actuated assemblies designed for continuous operation

Mechanisms engineered for repeatable, reliable motion under tight tolerances

Integration with sensors, embedded systems, and robotics control

Design for Scale & Production :

Lead mechanical DFM for both low and high-volume manufacturing

Translate prototypes into production-ready assemblies capable of thousands of units annually

Establish supplier and contract manufacturing relationships for complex components

Create build-to-print documentation that ensures repeatability and cost-effective assembly

Ground-Up Product Development

Own mechanical architecture from concept to production release

Balance mechanical innovation with manufacturability and serviceability

Design mechanisms for robustness, reliability, and field maintenance

Ensure compliance with healthcare and pharmaceutical handling standards

Test, Validation & Reliability

Lead mechanical design verification and validation (DVT)

Implement reliability testing to achieve 99.99%+ uptime

Conduct FMEA and risk mitigation at the mechanism level

Drive continuous improvement through field data and iterative design refinement

Who You Are

Experience

5+ years hands-on mechanical engineering experience designing complex electromechanical mechanisms

Demonstrated ability to take mechanisms from concept through production release

Deep knowledge of machining, sheet metal, injection molding, die casting, and assembly

CAD mastery in SolidWorks, Creo, or equivalent, including high-fidelity master modeling

Technical Excellence

Expertise in kinematics, motion, precision linkages, cams, and gear trains

Strong experience in mechanism integration with electrical, control, and software systems

Proven ability to design robust, repeatable, and high-speed mechanisms for continuous operation

Skilled in manufacturing documentation, DFM / DFA, and production scale-up

Culture Fit

Bias toward action : prototype, iterate, refine

Hands-on doer : you design, test, and problem-solve directly

Scrappy, low-ego, mission-driven, and highly collaborative

Why Join

True mechanical ownership from concept to national deployment

Build mission-critical mechanisms integrated with AI, robotics, and autonomy

Work with founders with Tesla- and Zipline-scale engineering.

Solve mechanical and systems-level problems at the cutting edge of robotics
