Software Engineer II - 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.

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. 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 Software Engineer II on Stacklok's core platform team, you will help build and harden the systems behind Stacklok Enterprise, the production distribution of ToolHive, the open source platform for running and governing MCP servers. This is a hands-on role with real independence.

You will deliver features and fix issues across the systems that let Fortune 500 and Global 2000 companies run AI agents securely at scale, from the runtime that isolates MCP servers and the Kubernetes operator that manages them to the gateway, registry, and identity layers. You will go deep in one area while building a system-wide understanding of how the whole platform fits together. The timing is what makes it compelling.

Customers are signing on now, the platform is being hardened for their production environments, and you will build alongside engineers, managers, and product partners defining this category as it emerges. What Success Looks Like: First 6-12 Months Ramped quickly on the platform codebase and began contributing independently, self-organizing on tasks without needing close guidance. Shipped your first features and fixes into an enterprise release within the first few months, then delivered core platform work consistently thereafter.

Resolved assigned production issues within SLA, keeping enterprise customers unblocked and their deployments stable. Supported users in the open-source ToolHive community, helping them resolve issues and get more value from the platform. Strengthened the team by reviewing pull requests thoughtfully and building strong working relationships across engineering and product.

In This Role, You Will Build and deliver features across the platform services that make up Stacklok Enterprise, including the runtime, Kubernetes operator, gateway, and registry. Fix bugs and harden platform systems for enterprise production use, improving stability across customer deployments. Write testable, readable code that accounts for edge cases and error handling, and produce clear design docs for the work you take on.

Review pull requests and contribute to design discussions, working alongside technical leads, product, and fellow engineers on shared platform efforts. Plan and sequence your own tasks and small epics independently, knowing when to pull in a teammate or escalate a design question. Contribute to the open-source ToolHive codebase and collaborate with community contributors on shared work.
