Because our services are central to how every product and feature reaches the edge, this role offers a unique opportunity to partner with internal teams across the organization to shape, scale, and secure the core Fastly experience that our customers rely on every day. As a Staff Software Engineer, you will join a talented group of engineers who solve complex problems in high-availability systems within a supportive environment where teammates genuinely enjoy working together. If you are a motivated engineer who thrives on solving interesting problems at scale while fostering a culture of high trust, mutual respect, and shared ownership, you’ll find a rewarding home here.

What You'll Do

• Support, deploy, and share responsibility for large scale Perl production systems that store and ship configuration changes to thousands of nodes globally.
• Drive architectural and operational improvements by evolving complex legacy systems into maintainable, performant Go microservices.
• Provide technical leadership of engineering projects, coordinate with project stakeholders, and motivate progress.
• Collaborate across engineering teams to ensure our configuration systems meet the requirements for new features and capabilities.
• Mentor and support other engineers, cultivating an environment of knowledge sharing, innovation, and teamwork within the engineering organization.
• Participate in an on-call rotation.

What We're Looking For

• Significant domain-relevant engineering experience building highly reliable distributed systems. Most Staff Engineers at Fastly have at least 7 years of related experience
• A solid understanding of the Go programming language.
• A pragmatic approach to legacy systems, including experience in or a willingness to learn Perl to support, troubleshoot, and enhance our core infrastructure.
• The ability to drive and deliver complex projects that span multiple teams and require cross-organizational influence.
• A communicative and empathetic teammate who works effectively in a remote environment and is comfortable with asynchronous workflows.
• An adaptable problem-solver who learns from mistakes, navigates ambiguity with ease, and balances short-term delivery with long-term quality through thoughtful tradeoffs.

We’ll be super impressed if you have experience in any of these:

• A background writing production-level code using the Perl programming language.
• Familiarity with containerization systems and platforms such as Kubernetes and Docker.
• Exposure to monitoring solutions such as Prometheus and Grafana.
