Senior Mechanical Design Engineer, Devices

South San Francisco, CA

At Plenty, we’re on a mission to give people in local communities everywhere access to the freshest, most amazing tasting produce possible. And to do so in a way that’s better for the planet.

Engineers at Plenty are revolutionizing the way humans grow food. We are seeking a Senior Mechanical Design Engineer to develop high volume grow lighting systems and devices to provide our plants with the optimal growing conditions to enhance flavor and nutrition. Plants solely rely on the energy from lighting for growth so this role has a direct impact on the quality and quantity of our yields.

About the Role

As a Senior Mechanical Design Engineer at Plenty, you will be responsible for creating the equipment that will differentiate Plenty Farms from all other farms, which will ultimately result in our produce looking and tasting better than anything that exists today. You will design and commission devices that are robust, efficient, and cost-effective. These systems will begin as prototypes and over time become products built in the hundreds or thousands. Additionally, you will be responsible for driving a passionate and dynamic team that is developing this new technology from the ground up and implementing it at scale.

Type of Role


What You'll Do

  • Learn a lot about light, plants, and the amazing process of photosynthesis

  • Have full product design responsibility, from concept through production launch and ramp

  • 3D design of complex parts and assemblies

  • Develop new technologies to advance lighting product performance while driving down cost and increase reliability

  • Early process development, testing, and analysis

  • Hands-on prototyping

  • Define specifications (dimensional, functional, performance, manufacturing)

  • Perform reliability and engineering validation testing to prove specifications have been satisfied and that your products are built to last

  • Meticulously release of 2D & 3D part and assembly drawings using product lifecycle management (PLM) tools

  • Root cause test failures and production problems

  • Collaborate with other teams inside Plenty (automation, plant science, supply chain, farm operations etc.) to optimize the system-level performance of our farms

  • Work closely with suppliers to ensure parts are fabricated and assembled in spec, on time, and within budget

What We're Looking For

  • BS in Mechanical or Electromechanical Engineering or equivalent

  • A builder and designer

  • 4 - 8 years of relevant experience

  • Proficiency in CAD modeling. CATIA V5/V6 experience a plus but not mandatory. Solidworks also a plus, but not mandatory

  • Experience in designing for medium and high volume assembly

  • Someone creative, self-motivated, and curious

  • Strong engineering fundamentals in mechanics, heat transfer, fluids, and electronics

  • Exemplary verbal, visual, and written communication and collaboration skills

  • A highly technical equipment development leader with an exceptional track record of project execution

  • Experience with various manufacturing processes such as plastic injection molding, machining, extruding, welding/brazing, plating, heat treating, and bonding.

  • Experience with design of wire harnesses, interconnects, and electrical enclosures

  • Direct machine shop and assembly skills a plus.

  • Success in full lifecycle project ownership of multiple, highly complex electro-mechanical products

  • Experience defining test plans, designing test setups, and analyzing data

  • Expertise in designing mechanical components, equipment, fixtures and tooling in CAD

  • A detail oriented personality with solid documentation and reporting skills.

About Plenty

Plenty is here to change the way people eat, making extraordinary flavor and nutrition more available in a way that's better for people and the planet. We build farms that can put craveable flavor first while delivering exceptional yields. And our produce is always pesticide-free and grown using less than 1% of the land and 5% of the water of outdoor farming.
