About Calectra:

Calectra is on a mission to electrify and decarbonize high-temperature industrial heat.

Our human societies are dependent on materials like cement, steel, glass, and chemicals. The process heat required for the production of these critical materials makes up a quarter of global energy consumption. Today, this process heat is fossil-based and accounts for 10% of global CO2 emissions. With many of these material production processes requiring very high-temperature heat, lower-cost alternatives to fossil fuel combustion have been difficult to develop.

Calectra is developing a novel thermal storage technology to lower the costs and emissions of high-temperature process heat for manufacturing industries. The Calectra thermal storage technology converts low-cost, off-peak, renewable electricity into high-temperature heat and delivers it to industrial manufacturers on demand. Calectra’s co-founder & CTO, Nate Weger, worked on the technology concept during his PhD at UC Berkeley / Lawrence Berkeley National Laboratory.

Calectra’s co-founders, Nate and Pauliina, met at the US Department of Energy’s Cradle to Commerce program in 2023. Since then, the Calectra team is grateful to have been supported by Activate, NYSERDA, US Bank Foundation, and the California Energy Commission. We are a mission-driven and action-biased team aiming to make a dent in the climate crisis with Calectra.

We are seeking our fifth full-time team member, an Electrical Engineer, to source and test the electrical components of the thermal storage system, then implement those components in a laboratory-scale system with an eye toward industrial-scale operation. In this position, you will lead the electrical development of Calectra’s technology, overcoming the challenges that come up as we pursue the demonstration of a more complex and higher power system, and building a thermal storage system that is low-cost, safe, and reliable. Join our team to electrify industrial process heat!

What you’ll do:

  • Source and implement electrical components and sensors for lab-scale prototype

  • Control and analyze electrical performance, energy and mass flow, and system stability

  • Operate high-power (10-100 kW) conversion equipment

  • High-level architecture design of industrial-scale (1-100 MW) electrical systems

  • Perform cost studies on electrical system unit economics

  • Practice safe operating principles for working in high-power environments

  • Travel to and work on industrial manufacturing sites

  • Collaborate with Calectra team members and partners

What you’ll bring:

  • B.S./M.S./PhD in electrical engineering or related field

  • Experience operating 10-100 kW electrical components

  • Understanding of electrical system design and operation at the laboratory and industrial scales

  • Expertise in electrical component selection, installation, and operation

  • Experience with automation and controls equipment (motors, PLCs, sensors, etc.)

  • Proficiency with common electrical lab equipment (signal generators, power supplies, DAQs, soldering station, etc.)

  • Ability to work productively and respectfully on a collaborative team

  • Resiliency in the face of significant challenge

Would be nice:

  • Experience working with industrial-scale electrical equipment

  • Experience building, testing, and scaling new technologies

What we offer:

  • Annual salary of $102,000 - $140,000

  • Company equity

  • Healthcare, dental, vision insurance for employees and dependents

  • Unlimited vacation

  • Unlimited sick leave

  • 401(k) plan with company match

  • Paid family leave

We are dedicated to building a diverse and inclusive workforce. If you’re excited about this role, but do not meet 100% of the qualifications listed above, we encourage you to apply.
