Senior Software Engineer - Platform

Role Description

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.
• Make design tradeoffs that determine how your subsystems evolve.
• Mentor the engineers building alongside you.

The timing is compelling as 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.
• Took a rough or partial subsystem to production-hardened, 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.

Qualifications

• Deep proficiency in Go, with a proven track record building production-grade backend or platform systems.
• Knowledge of Kubernetes and container technologies, including operators, isolation, and networking in production environments.
• Proven track record designing and shipping complete systems end to end, from architecture through production and iteration.
• Demonstrated experience as a tech lead: mentoring engineers, driving code review, and raising the quality of a team's work.
• Experience designing for reliability and observability, building systems with monitoring, testing, and evaluation in mind.
• Proven track record building or operating platform services such as gateways, registries, runtimes, or deployment tooling.
• AI-first mindset: integrates AI tools into development and helps improve how the team ships.
• Excellent written and verbal communication skills.
• Startup mentality and intrinsic motivation: self-directed and hands-on.

Requirements

• Experience with production-grade backend or platform systems.
• Familiarity with MCP is a plus.

Benefits

• Competitive compensation and equity.
• Comprehensive medical, dental, and vision coverage.
• Flexible PTO and paid holidays.
• Paid parental leave.
• Flexible, hybrid-or-remote work environment.
• Team offsites in unique destinations to collaborate and connect in person.
