Software Development Engineer - API Services

The API Services team owns critical services to ensure the performance and reliability of Fastly's Control Plane. As a Software Development Engineer, you will implement features and improvements to these high-throughput, globally distributed systems, working closely with more senior engineers and other internal Fastly teams to support critical components of our infrastructure.

What You'll Do

• Implement projects and features that require interaction with neighboring systems, working across groups to solve issues and implement changes
• Contribute to and facilitate team discussions, respecting and incorporating differing opinions
• Provide useful design and code review feedback to your teammates
• Contribute to the core infrastructure and platform needs of the team by working with tools and frameworks like Terraform, Jenkins, Kubernetes, and Chef
• Help evolve manual tasks into more reliable, automated systems
• Communicate effectively with both technical and non-technical teammates
• Help onboard and support new team members
• Take the lead in solving problems of diverse scope, with guidance from senior teammates as needed
• Participate in an on-call rotation

What We're Looking For

• You have 1-3 years of related development experience
• Working knowledge of GoLang, with a desire to build deeper hands-on expertise
• Exposure to cloud providers (AWS, GCP), containerization (Docker, Kubernetes), and infrastructure as code (Terraform)
• Good understanding of core engineering concepts within your functional area
• Able to execute on features that require interaction with neighboring applications or services
• Growing understanding of distributed systems and microservices architecture
• Comfortable taking on well-scoped projects with support from senior teammates
• Good written and verbal communication skills
• A great teammate: communicative, collaborative, empathetic
• Eager to learn new domains, grow your skills, and take on more scope over time
• Open to working with teams distributed across different time zones

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

• Envoy
• API Gateways
• Varnish, VCL

Work Hours:

This position will require you to be available during core business hours (Mountain/Pacific Time) and occasional nights and weekends as required for on-call support.

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
• Denver, CO

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 remote candidates within the US.

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

Salary: 

The estimated salary range for this position is $155,370 to $186,444. 

Starting salary may vary based on permissible, non-discriminatory factors such as experience, skills, qualifications, and location.

This role may be eligible to participate in Fastly's equity and discretionary bonus programs.

Benefits: 

We care about you. Fastly works hard to create a positive environment for our employees, and we think your life outside of work is important too. We support our teams with great benefits that start on the first day of your employment with Fastly. Curious about our offerings?
