Senior Product Engineer, Full Stack & AI, Climate Tech

Every day, we work together for what matters – bold, swift, and equitable climate action.

ABOUT THE ROLE

At 3Degrees, a Certified B Corporation driving climate action, we’re building the next generation of digital products that accelerate the energy transition. You’ll join a small, fast‑moving team that designs and ships modern SaaS applications with state‑of‑the‑art AI and agentic capabilities powering our environmental commodities business – from Energy Attribute Certificates (EACs) and carbon credits to supply chain reductions and clean fuel standards.

You’ll join as a founding member of a new agile unit within 3Degrees that is made up of technical leadership, execution, and product, which gives you the opportunity to shape what we build and how we work. Reporting to the Tech Lead, Next‑Gen Products, and working closely with our Head of Product, you’ll co‑own the end‑to‑end delivery of critical product slices – crafting intuitive UIs, designing resilient backends, and integrating modern services, while also bringing cutting‑edge AI functionality into our products. From prototype to production, reliability, safety, and measurable impact are non‑negotiables.

This is a role for builders who thrive at startup velocity inside an established company : you’ll move fast, learn new tools on the fly, and apply your creativity to solve hard problems. At the same time, you’ll have the chance to shape products that matter – ones that help the world decarbonize faster.

This is a full‑time role reporting to the Tech Lead, Next‑Gen Products. We value camaraderie, team collaboration, and the benefits of in‑person connection, while offering flexibility. For this role, we prefer candidates to join us in a voluntary, flexible hybrid work style in our San Francisco Bay Area office. We may also consider candidates who are able to join us at one of our office hubs in Portland, OR; Portland, ME; or New York, NY.

For exceptional remote candidates, we strongly prefer those located in states where we are currently eligible to hire : CA, OR, NY, WA, ME, TX, CO, MI, FL, MA, MN, VA, DC, GA, UT, and IL. While we prioritize candidates in, or open to relocating to, these states, we may consider outstanding remote candidates from other US states. Please note that hiring in a new state would involve evaluating the implications of establishing a new hiring presence there. Additionally, 3Degrees does not provide relocation assistance for this position.

Please Note : 3Degrees does not provide sponsorship or work authorization assistance; therefore, pre‑existing right‑to‑work status is a prerequisite to be considered for this position.

WHY JOIN US

ABOUT YOU

You are a hands‑on product engineer with a strong track record of shipping modern SaaS web applications end to end.

You actively use AI in your own workflow and know how to responsibly integrate LLMs and agentic techniques into production‑grade products. You’re curious, pragmatic, and excited to apply your skills to climate tech with real‑world impact.
