Job description

Join Renewell and drive innovation at the cutting edge of the energy storage and well remediation sectors.

Our breakthrough technology tackles the climate crisis by converting inactive oil and gas wells into gravity-based energy storage systems—providing reliable renewable power while cleaning up millions of idle wells across the U.S.

This is a rare opportunity to be one of the early hires at a mission-driven startup that is entering a promising growth phase with ~$15M raised to-date (VCs, US DOE (ARPA-E), CEC, etc.), regulations recently changed in 3 states, and deployment poised to 5-11x in the next 2 years. If you’re excited by hands-on engineering, creative problem-solving, and scaling a revolutionary technology in a high-paced environment, let’s talk.

Role : As the Senior R&D Engineer, you’ll lead the design, prototyping, testing, and optimization of our 3+ novel energy storage systems (only 1 is public). You’ll own key technical projects, collaborate with internal and external partners, and help transition our concepts into commercial-ready solutions. The role is highly hands-on, dynamic, and growth-oriented—perfect for engineers who thrive on tackling big technical challenges with creativity and rigor. As part of a high-growth startup, you will be challenged to rapidly expand your skillset, with ample opportunity to grow into a leadership role.

Responsibilities :

  • Design, build, and iterate on prototype systems that repurpose idle wells for energy storage
  • Develop technoeconomic models to evaluate design trade-offs and system economics
  • Lead lab and field testing, including test plan design, setup, execution, and analysis to maximize efficiency, lifetime, safety, and economic benefit of this technology
  • Collaborate across mechanical, electrical, and software teams for system integration
  • Manage vendors, contractors, and consultants to support R&D and pilot deployments
  • Travel to vendors, customers, and installation sites (10–25%)
