Full time, Hybrid - remote work with regular on-site time at our equipment.

Location: Hybrid with strong preference to Western NY State, Juneau AK, Tulsa OK or Washington State.

We are looking for a passionate person who wants to create breakthroughs in untapped potential for significant climate impact - while working with and benefiting rural communities. We are a small team. This role is the mechanical engineering function, not a seat on a large bench — you will own the mechanical part of the hardware stack.

Job Description

  • Own the mechanical design of our flare and contribute to site design.
    • Primarily: sheet metal/welded/plumbing parts, and assembly design.
  • Perform site sizing/piping design based on farm size data and models.
  • Own mechanical manufacturing documentation (part and assembly drawings, documentation, procedures, etc.)
  • Work with the operations team to coordinate manufacturing of flares and custom assemblies.
  • Interface with electrical engineering team on integration of electrical subsystems.
  • Participate in design reviews
  • Occasional travel to farm sites.
    • Participate in 2-4 field installs per year to feed back improvements to the design.

Required

  • 5+ years of mechanical design experience taking hardware from concept through manufacturing.
  • Understand basic combustor design for biogas or other low-BTU fuels.
  • Strong CAD skills. We use Fusion 360; experience in another package is fine if you’re willing to learn Fusion.
  • Fluids experience (e.g. modeling of pressure-flow characteristics of gasses in pipes)
  • Working knowledge of process instrumentation and measurement systems (flow, pressure, temperature sensors, 4-20mA sensors, etc.).
  • Hands-on experience with mechanical assemblies and light fabrication. Field installs will require mechanical assembly skills.

Nice to have

  • Sheet metal design experience. Useful, but you can learn it here.
  • Knowledge of sulfidation and high-temperature corrosion.
  • Experience with hardware deployed in remote or unattended field environments.

If you have a sample drawing package or assembly documentation you can share, include it with your application.

Compensation: $90-$140k/year depending on location and experience, plus employee stock options.

Benefits: 15 days PTO, 1 floating holiday, 401(k) with company matching, health & dental premium reimbursements.

Our company:

  • Small, fun, fascinating, highly driven team: our teammates have worked in Antarctica, on space applications, and built underwater submarines, pandemic ventilators and nuclear reactors.
  • High-impact mission and large growth potential - supported by well known investors: Lower carbon, Climate Capital, Woven Ventures, Third Derivative, Grantham Foundation, Arpa-e, Mulago and some amazing angel investors
