Sr. Software Engineer - Stacklok Enterprise

Stacklok is led by CEO Craig McLuckie and CTO Joe Beda, two of the creators of Kubernetes. As AI reshapes how software is built and used, we're building the foundation enterprises need to adopt it with confidence.

We're building the control plane for enterprise AI agents, enabling organizations to run, govern, and secure them on the infrastructure they already trust. Through Model Context Protocol (MCP) servers running across Kubernetes and private cloud environments, AI agents can securely connect to internal data and systems while meeting the security, compliance, and operational requirements of highly regulated and security-conscious organizations. We've also extended this foundation to the model layer with an enterprise AI gateway.

The Stacklok Enterprise Platform is built on ToolHive, our open source MCP platform, and is already being adopted by leading technology companies and organizations in regulated industries. We also help maintain the official MCP registry and contribute openly to the community shaping the future of enterprise AI.

Location

This is a remote role based in North America, with a strong preference for candidates located in the U.S. Eastern Time Zone.

The Opportunity

Enterprises are moving AI agents into production, and they want to run them the way they run everything else: on their own Kubernetes clusters, behind their firewall, and connected to the identity systems they already use. Stacklok Enterprise, our commercial platform for running and governing AI agents, is built for that, by a team whose founders co-created Kubernetes.

As a Senior Engineer on the core platform team, you will design and build major parts of the platform and own them from design through production. That work runs in customers' Kubernetes environments, so your design tradeoffs shape how the product holds up in the field. The areas you own will shift as the product grows, and you will mentor the engineers building alongside you.

Customers are onboarding now. As one of the key engineers helping them reach production, you will also work with some as design partners on our newest features and products. It is a high-ownership role in an emerging category, with a short path from customer feedback to what ships.

What Success Looks Like: First 6-12 Months

- Designed and shipped a complete subsystem end to end that is now running in production for enterprise customers.

- Helped take one or more customers from proof-of-concept to production on their own Kubernetes, and turned their feedback into a platform feature.

- Raised the team's bar by mentoring engineers and strengthening the product engineering culture.

- Improved how the team ships changes to customers, including where AI-assisted workflows helped and where they created rework.

- Became the owner and go-to decision maker for one or more platform areas, with the team routing design questions your way.

In This Role, You Will

- Own the design and implementation of platform subsystems in Stacklok Enterprise end to end, from technical design through production and ongoing improvement.

- Write production Go code for commercial software that runs reliably in customer Kubernetes environments, with observability, testing, and error handling built in.

- Make the design tradeoffs for the areas you own with product and engineering leadership, and mentor the engineers building alongside you.

- Work with customers to successfully operationalize the Enterprise Platform and turn their feedback into product improvements.

- Contribute to the open-source ToolHive codebase and collaborate with community contributors on shared work.

- Apply AI-assisted workflows and strengthen reusable tooling and playbooks so each engagement moves faster for the team.
