About the company

Our client is an energy technology company.

The role

Raydar is recruiting for this role on behalf of our client. Lead the mechanical design of an autonomous outdoor robot, taking it from early concept through prototyping and into a small production fleet. The work is hands-on and spans design, fabrication and field testing, in close partnership with electrical and mechatronics colleagues.

What you'll do

- Own the overall mechanical architecture of a mobile field robot, including frame, tooling, material handling, drivetrain and locomotion for rough terrain.

- Design, build and iterate on prototypes quickly, machining parts, working with fabrication shops and testing hardware outdoors.

- Select and integrate actuators, sensors and power distribution, working closely with the electrical and mechatronics engineer.

- Carry out structural and dynamic analysis covering loads, vibration, fatigue and stability.

- Prepare the design for a small production run with attention to manufacturability, reliability and ease of field service.

Requirements

What we're looking for

- 7 to 10+ years of experience in mechanical or robotics engineering.

- A track record of personally driving a combined mechanical and electrical machine from first idea to fielded units, not only drafting or passing designs to others.

- Experience at a robotics company building machines that operate in harsh outdoor conditions, such as construction, mining, energy or agriculture technology.

- A bachelor's or master's degree in mechanical engineering or a related discipline.

- Experience designing drivetrains, actuation and locomotion for wheeled or tracked mobile robots, including motor sizing, gearboxes and suspension.

- Strong rapid prototyping and hands-on fabrication skills, comfortable in both a shop and the field.

- A self-directed working style and the ability to clear obstacles without waiting for management direction.

- Ability to work on-site five days a week.

- US work authorization.

Bonus points

- Prior time at a demanding, quick-moving startup or technology employer.

- Background in hydraulics or heavy machinery for ground-engaging tools.

Benefits

- Base salary: USD 150,000 to 250,000 per year

- Equity

- Health, dental and vision coverage

- Flexible time off
