ROLE AND RESPONSIBILITIES

Senior Engineering Manager, Platform Security

The Platform Security function at Fastly plays a critical role in maintaining and evolving the platform that powers a significant portion of internet traffic worldwide. This function delivers tooling and PKI solutions across a global network that spans six continents and boasts over 353 terabits per second of connected capacity.

As the Senior Engineering Manager of the Platform Security team, you will oversee and scale the technical leadership across multiple engineering projects responsible for foundational infrastructure services. You will be responsible for defining the multi-year technical vision and ensuring strategic alignment with executive leadership. You will foster a culture of technical rigor, operational excellence, and innovation across the entire platform domain, moving beyond single-team execution to driving cross-organizational advancements.

This is not a traditional "keep the lights on" operational role. Reliability is critical, but the real focus here is on innovation—driving strategic improvements, building foundational infrastructure for the future, and shaping how secure orchestration and trust services evolve at Fastly and beyond.

What You'll Do:

• Define the long-term strategic vision and multi-year technical roadmap for the Platform Security domain, ensuring these investments align with Fastly’s overall business and security objectives.
• Oversee and develop a high-performing team that includes engineers and principal-level individual contributors, focusing on organizational structure, talent development, and scaling team capabilities to meet future demand.
• Collaborate with cross-functional stakeholders using a product-owner mindset to define clear roadmaps and priorities.
• Drive organizational-wide adoption of best practices for operational excellence, reliability, and security, establishing metrics and accountability across all platform services.
• Clearly communicate the function’s strategy, progress, and risk profile to executive leadership and technical stakeholders across the company.
• While you will not be expected to write code, you will need to leverage deep, related technical experience to succeed in this role.

BASIC QUALIFICATIONS

What We're Looking For:

• 4+ years of experience managing Platform or Site Reliability Engineering teams.
• 10+ years of related technical experience with distributed systems and infrastructure as code.
• Demonstrated ability to drive a durable technical roadmap and facilitate effective collaboration in cross-functional teams.
• Experience with secrets and workload identity management, including using tools like SPIFFE, SPIRE, HashiCorp Vault, etc.
• Experience building and automating large scale production infrastructure in public cloud and on-prem environments. Using TFE or similar technologies.
• Extensive hands-on experience working in a Linux environment with a solid understanding of system internals and performance optimization.

PREFERRED QUALIFICATIONS

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

• Experience with Kubernetes, PKI, and configuration management tools like Chef.
• Proficiency in Python or Go.
• Migrating physical or cloud-based workloads to new hosting platforms.
• Experience collaborating with compliance/security teams.

Work Hours:

This position will require you to be available during core business hours. It may also require occasional nights and weekends as necessary to support any on-call coverage.

Work Location(s) & Travel Requirements:

This position is open to Hybrid And Remote Work Locations.

The preferred locations for this position are:

• San Francisco, CA
• New York, NY

Fastly currently embraces a largely hybrid model for most roles which allows employees flexibility to split their time between the office and home.

There is a strong preference for Hybrid near a local office. However, we may be willing to consider exceptionally qualified remote candidates within the US.

This position may require travel as required by your role or requested by your manager.
