Most tech sectors sell software and scale with near-zero marginal cost. Climate tech is structurally different. Many climate tech companies involve physical infrastructure — solar panels, EV chargers, battery storage, grid hardware — which means the roles that matter are different from pure software companies. Project developers who manage permitting and site acquisition, field operations professionals who deploy and maintain hardware, and supply chain managers who navigate manufacturing constraints are as important to climate tech companies as engineers and product managers. This opens up the sector to a broader range of career changers than pure software tech does. If you have experience in construction, utilities, logistics, or operations, you are more relevant than you might think.
The fellowship pipeline that most people do not know about
Climate Draft is a free program that matches climate-interested professionals with climate tech companies for fellowships. MCJ Collective runs the largest network of climate professionals and investors, including a job board that is the first place many climate companies post open roles. Third Derivative is a climate tech accelerator that also connects professionals with portfolio companies. These programs exist because the supply of climate-domain expertise is limited relative to demand, and they are actively recruiting people transitioning from other sectors. Applying through these networks is often faster and more effective than applying cold through job boards, because the companies involved are specifically looking for people who are making the transition intentionally rather than people who have always been in climate.
What domain knowledge actually helps in which roles
For PM roles in grid software or energy management, understanding electricity markets — how utilities buy power, how demand response works, what the duck curve is — is the domain knowledge that differentiates candidates. For data roles in carbon accounting, understanding measurement methodologies like GHG Protocol and Scope 1, 2, and 3 emissions is the domain knowledge that matters. For operations roles in EV charging, understanding grid interconnection and permitting processes is the domain knowledge that makes candidates competitive. None of these require a technical degree. They require study and genuine interest — the kind of knowledge you can build by reading industry publications, taking a free online course on electricity markets, or spending a month on the EPA's emissions resources. The climate tech companies that are growing fastest are not expecting candidates to arrive with years of domain experience. They are expecting candidates who have done the work to understand the sector they are entering.
