Sr. Software Engineer - Platform

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 from experimentation into production, and they need infrastructure that is secure, auditable, and runs behind their own firewall. As a Senior Engineer on Stacklok's core platform team, you will own subsystems within Stacklok Enterprise, the production distribution of ToolHive, the open-source platform for running and governing MCP servers. This is a role with real ownership. You will design and deliver whole subsystems end to end, anchor meaningful projects, and lead them from design through implementation and into production. These are the systems that let Fortune 500 and Global 2000 companies run AI agents securely at scale. You will make the design tradeoffs that determine how your subsystems evolve, and mentor the engineers building alongside you. The timing is what makes it compelling. Customers are signing on now, the platform is being hardened for their production environments, and you will solve hard infrastructure problems in an emerging category alongside a team whose founders co-created Kubernetes. 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. Became the trusted owner and go-to decision maker for one or more platform areas, with the team routing design questions your way. Took a rough or partial subsystem to production-hardened, measurably improving its reliability or scalability for customer deployments. Raised the team's bar by mentoring SWE and SWE II engineers and strengthening the code review culture. Improved how the team ships by tightening development velocity, including where AI-assisted workflows helped and where they created rework. In This Role, You Will Own the design and implementation of...
