Senior Software Engineer, Platform Security

About the Role

Fastly is seeking a Senior Engineer to represent our Platform Security team, with a specialized focus on Trust and Identity infrastructure. This is a high-impact individual contributor role for a technically exceptional engineer with deep experience in secure platform services at scale.

You will drive the execution of initiatives foundational to Fastly’s internal authentication, identity, and access control systems, helping shape Fastly’s internal trust architecture for years to come.

What You'll Do

• Work alongside peers to define the long-term vision for trust and identity infrastructure and translate it into tangible execution plans aligned with business goals.
• Design and implement scalable internal trust solutions such as secrets management, PKI, and authentication services.
• Tackle ambiguous, technically demanding initiatives with multiple stakeholders and organization-wide impact.
• Partner deeply with Product, Security, Compliance, and other Engineering teams.
• Proactively identify potential situations that could negatively affect the business or customers and develop strategies to mitigate these risks before they escalate.
• Establish and evangelize technical standards, code quality, reliability, and operational maturity.
• Participate in on-call coverage (occasional nights and weekends as necessary).

What We're Looking For

• 5+ years of experience in a technical capacity as an individual contributor in areas such as Privileged Access Management (PAM), workload identity management, LDAP, secrets management, or trust systems.
• Strong systems engineering background with deep experience in Linux, networking, and distributed systems.
• Demonstrated expertise in modern programming languages (e.g., Go, Python, Rust) and infrastructure tooling (e.g., Terraform, Vault, Consul, Chef).
• Passionate about demos and feedback-driven work.
• Excellent written and verbal communication skills, with the ability to clearly articulate complex technical concepts and produce comprehensive documentation.
• A collaborative mindset with experience working across cross-functional teams.

Bonus Qualifications

• Experience implementing zero-trust architectures or identity-aware access proxies.
• Experience designing scalable secrets lifecycle management workflows.
• Working with PKI and certificate automation at scale.
• Contributing to open source identity or security tooling.
• Experience with cutting-edge technologies (e.g., SPIFFE/SPIRE, modern PAM tooling).
