Kubernetes helped give enterprises more freedom over where and how they run software. Now we’re bringing that same open approach to AI agents.

As AI agents take on more autonomous, long-running work, enterprises need infrastructure to run them securely and reliably at scale, without giving up control of their data, systems, or models. We’re building open, Kubernetes-native infrastructure that brings together agent execution, secure access to tools and systems, and centralized controls for identity, permissions, and policy. This is an opportunity to help shape a foundational layer for enterprise AI while the architecture is still being defined.

We build in the open alongside the community. Our open source projects include ToolHive, an MCP platform that secures more than 20 million tool calls each month, and Mecatl, a cloud-native agent harness. Our commercial offering, Stacklok Enterprise, extends these capabilities with an AI gateway, centralized identity, policy enforcement, and observability.

This is a remote role based in North America, with a strong preference for candidates located in the U.AI agents are moving into production, and the harness that runs them is becoming critical infrastructure. Enterprises need that harness to be secure, auditable, and portable across models, clients, and deployment environments. It provides the agent loop, tools, permissions, hooks, delegation, and durable sessions for running agents as production workloads on infrastructure you operate.

As a Software Engineer II on the Mecatl team, you will build the platform that agents run on, and you will build it with agents. You will deliver features and fixes across the engine, the Kubernetes-native runtime, the client surfaces (gRPC, the TypeScript SDK, and the terminal client), and the permission and governance layers that make agent behavior protected to trust. We are also an AI-first engineering team. We use agents throughout our own development lifecycle, and we are still working out what good looks like. Ramped quickly on the Mecatl codebase and its development process,



and began contributing independently without needing close guidance.

Shipped your first features and fixes within the first few months, then delivered core harness work consistently thereafter.

Owned a product-minded improvement end to end, from understanding how people use Mecatl to shipping a change and learning from the result.

Contributed a concrete improvement to how the team uses AI in development, such as a workflow, evaluation, guardrail, or measurement approach that the team adopted.

Strengthened the team and community by reviewing pull requests thoughtfully, including AI-assisted changes, and helping open source users get more from Mecatl.

Write testable, readable code that accounts for edge cases and error handling, produce clear design docs for the work you take on, and review pull requests, including AI-assisted changes.

Use AI agents as a core part of your own workflow, and bring a critical eye to what they produce: review it, test it, and own it.

Find where your AI workflow breaks down on Mecatl work, experiment to fix it, and bring structured findings back so the team gets faster and better, not just busier.

Apply security judgment to AI-assisted development, including permissions, secrets handling, untrusted content, and the limits of what an agent should be trusted to do.

Proficiency in Go, writing clean, testable code that accounts for edge cases and error handling, plus clear design docs and thoughtful code reviews.

Demonstrated ability to deliver features independently across a backend or platform codebase, from implementation through testing and into a release.

A personal AI-assisted development workflow you can walk through, with a clear sense of where it helps, where it breaks, and its risks,



such as prompt injection and excessive agent permissions.

Prior experience building on or contributing to an AI platform or open source project is a plus.

Ideally, a product engineering mindset: curious about users and their problems, comfortable questioning requirements, and motivated by shipping something people use.

AI-first mindset: builds AI into the development workflow to accelerate delivery, improve the quality of what ships, and rethink how problems get solved.

Communication: excellent written and verbal communication, able to explain complex technical ideas clearly to technical and non-technical audiences.

In addition to base salary, this role offers equity and a comprehensive benefits package.

#LI-Remote

We are AI maximalists, confident in AI’s potential and committed to building technology people can trust. We use AI in our own work and experiment openly.

You’ll build alongside people with deep experience in open source, cloud-native technologies, security, and developer tools. We stay close to customers, use our own products, and share what we learn to keep improving. We offer competitive compensation and equity, comprehensive medical, dental, and vision coverage, and a flexible hybrid or remote work environment. Our benefits include flexible PTO, paid holidays, and paid parental leave, along with team offsites to collaborate and connect in person.

If you’re excited about what we’re building and want to work with people who care about their craft, community, and each other, we’d love to hear from you.
