We're looking for software engineers to help build the AI platform that powers our agents product. You'll be a technical leader laying the foundations for agentic AI at Watershed - designing the orchestration layer, controls, and tooling that let our product teams ship reliable, observable AI features on top of a wealth of operational sustainability data. In this role you will: * Design and build the agent infrastructure that powers Watershed's products * Develop the observability and tracing layer for agent decisions, making it possible to debug, evaluate, and improve agent behavior at scale * Build evals, harnesses, and guardrails that turn agent capabilities into production-grade, dependable systems * Collaborate with product and other AI engineering teams to set product and technical strategy, and define the boundaries between autonomous agent behavior, deterministic code, and human oversight * Keep up with developments and state-of-the-art in AI and agent infrastructure to determine what is relevant to Watershed * Work closely with Watershed product teams to contribute your expertise to build agent experiences across the product * Write performant, well-crafted, tested, and maintainable code across our technical stack, It starts the same for every candidate: getting to know the team members through 1 to 2 conversations about Watershed, your experience, and your interests. Next steps can vary by role, but usual next steps are a skill or experience interview (e.g. a coding interview for an engineer, a portfolio review for a designer, deeper experience call for other roles) which leads to a virtual or in person interview panel. We prioritize transparency and lack of surprise throughout the process. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [This App Reached 10,000 Users in One Week.
