Senior Site Reliability Engineer

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion in signed contracts across commercial and US government customers, we're mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.

The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today's and tomorrow's massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.

With multiple launches in 2027 and plans to scale to 100 satellites a year, we're Building Bigger — helping develop the solar system and build toward a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a high-growth Series D-funded company, we'd love for you to apply.

The Role

You will be responsible for the core infrastructure and tooling used by the software team and larger Engineering org as we build and fly some of the largest spacecraft that have ever been flown.

In your first six months, you will directly shape the software solutions of our first Mega class satellite.

• Reduce operational toil through automation, tooling, and self-service platforms
• Partner with other technical teams to design controls, uphold security standards, and proactively mitigate vulnerabilities
• Lead high-impact reliability, security, and resiliency efforts that influence platform strategy, elevate engineering excellence, and enable critical business outcomes.

Qualifications

• Bachelor's degree in computer science, Information Technology or a STEM discipline or 5+ years of professional experience in Software Engineering, Site Reliability Engineering or DevOps
• Deep experience with cloud platforms (AWS, GCP, or Azure)
• 3+ years of Infrastructure-as-code deployment processes
• Production experience with Kubernetes and container orchestration
• Solid understanding of networking & Linux internals

Nice to Have

• Experience managing application deployment workflows
• Experience managing core infrastructure with high availability requirements
• Experience with high-volume manufacturing, aerospace, or other adjacent environments
• Experience writing Terraform, Ansible, or other common Infrastructure-as-Code and owning the full lifecycle of infrastructure deployments
• Experience working with mission-critical and sensitive systems
• Strong programming skills in at least one language (Go, Python, or similar)
• Track record of driving technical strategy and influencing across teams

Compensation and Benefits

• Base salary range for this role is $140,000 - $180,000 + equity in the company
• Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
• Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks

If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!
