Dive in and do the best work of your career rney alongside a strong community of top talent who are relentless in their drive to build the simplest scalable cloud. If you have a growth mindset, naturally like to think big and bold, and are energized by the fast-paced environment of a true industry disruptor, you’ll find your place here. We value winning together—while learning, having fun, and making a profound difference for the dreamers and builders in the world.

We are looking for a Senior Software Engineer II for the Action Runtime team. This team's mission is to build the execution layer for AI agents: tool execution environments and orchestration systems that let agents run code and take actions safely, fast, and  will help define what "good" looks like for agent execution at Digital Ocean — isolation guarantees, cold-start latency, throughput under concurrent agent load — then design, build, ship, measure, and operate those systems end to end.

This is a senior individual contributor role for a builder who can independently move from ambiguous customer and business needs to product planning, design and UX collaboration, technical design, production implementation, launch, and long-term maintenance. You should be comfortable working full-stack, partnering across product, design, and engineering, and making pragmatic technical choices in fast-moving agent tooling ecosystems.### What You'll Do
* Independently own and ship product features within Action Infrastructure from planning through design, implementation, launch, operations, and maintenance with high autonomy.
* Build production-grade third-party agent tools and supporting infrastructure, including MCP servers, tool schemas, authentication and secrets handling, rate limiting, observability, and safe execution boundaries.
* Create full-stack experiences for builders and operators to discover, configure, test, debug, and monitor agent tools.
* Collaborate closely with product, design, and UX partners to make agent-tool workflows understandable, trustworthy, and efficient for builders and operators.
* Define and improve quality bars for tools using evaluations, golden tasks, telemetry, error analysis, model and tool selection experiments, and production feedback loops.
* Translate business and customer requirements into clear, minimally complex technical designs that multiple teams can understand and execute against.
* Partner with product managers, designers, infrastructure teams, security, support, and other engineering teams to deliver reliable customer-facing capabilities.
* Guide technical decisions for a group of engineers, review code and architecture, and raise the team's bar for reliability, maintainability, and operational excellence.
* Operate what you build: participate in on-call practices, debug multi-system production issues, lead incident diagnosis when needed, and turn operational learnings into durable improvements.
* Track emerging agent tooling standards and practices, especially around MCP, evals, tool-use reliability, agent UX, and AI coding/agent environments, and apply them…
