Senior Software Engineer, Agent-Driven

About the role

This role blends traditional software engineering, agent management, and system-building.

Gravity (gravityclimate.com http://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.
