Senior Software Engineer, Agent-Driven

About the role

This role blends traditional software engineering, agent management, and system-building. Gravity ( gravityclimate.com ) is the top carbon and energy management company. Our product helps firms measure their carbon footprint, report it to regulators and investors, and actually implement cost-saving energy efficiencies that also reduce emissions. Some of the largest industrial, finance, consumer, and technology companies in the world use Gravity to report their carbon footprints to regulators and to save millions in energy costs. Business is booming, we are well-funded, and just moved into a lovely office in Jackson Square SF. Now is a pivotal time in technology and environmentalism. That is why we are hiring forward-looking engineers with strong conviction about the way software ought to be developed in 2026 and beyond. What winning looks like in this role Your first job is to produce software by driving a fleet of agents. This role looks like a hybrid of IC and manager: you are accountable for shipping code, but the way you do it is by writing, planning, sharing context, and coaching. Your tools will change as the frontier evolves, but for the moment we love Opus 4.5 via Claude Code & Conductor. You will open your IDE to read code and apply polish and hopefully not much else. You do not need to already work this way, but you need to be excited by the idea of learning. You will balance focus and context switching. Your other responsibility is to build the factory: the system by which we build software. You will update our system prompts, build automated verification loops so that agents can check their own code, and write skills so that our agents know the specifics of our codebase and domain. This is how we compound. Your third responsibility is to stay on top of new technology. For instance, Claude Code + Opus 4.5 was a key moment. The firms that harnessed it will spring ahead of those who didn't. You will be our radar. Finally, when it comes to what you are building, you will be the expert on agentic harnesses, evals, and best practices. Your experience wielding coding agents will directly translate into making the Gravity Agent the most powerful for our customers. The context ("Why Gravity, why now?") Carbon accounting is a complex domain, and products in the space thrive or die based on their data model. We have the best product because we can automate the most; we can automate the most because we have the best data model. Taste is the moat. Because our domain model is simpler and more powerful, our agents are able to automate increasing swaths of carbon accounting tasks, freeing up more resources to build the engine. The flywheel is turning. Further, a series of early technical decisions have allowed us to keep the team lean and high-leverage: everything is Dockerized, all logic lives on the server, we have static typing over the wire, we're API-first, pattern driven codebase, modular monolith, and state lives in very few places. The world also needs what we're building more than ever. AI demand is driving dirty energy generation back up, even as solar has recently become cheaper than natural gas. Beyond compliance and reporting, our customers look to us to help them navigate the unstable energy landscape of 2026. Don't just take our word for it: despite the political environment, we have grown the business almost 30x in 3 years and hope to do it again. The team is senior and full-stack. Everybody spikes high for agency, urgency, and customer obsession. Code review is optional; quality is mandatory. We believe small, conviction-driven teams adopting frontier tools will increasingly outperform larger, more conventional organizations. We are lucky and work hard. (but also have families and pastimes!). Fun trivia: my cofounder's great-uncle started the EPA. Who thrives in this role To get oddly specific: the ideal candidate might be a former athlete, enjoy Starcraft and board games, and burn through her monthly Claude Code tokens with two weeks to spare. They may like Emerson or Andy Grove, have a deep sense of craft, and hate tech debt. Or they may be completely different: we've found that great candidates come from many backgrounds and don't all match stereotypes. They non-negotiably: Hold themselves and their colleagues to a high standard of accountability Enjoy both rapid context switching and applying fastidious attention to detail Find it energizing to solve problems and build products Prize clear, crisp communication Are natural system builders and believe that quality software typically emerges from speed of delivery, not in spite of it They will hopefully have experience with some or all of: Golang, Postgres, React/Typescript, Docker, AWS, and Terraform. No carbon accounting knowledge required - you can learn. The team also skews comically high for yoga instructors and volleyball players, so if that's you, even better.
