Senior Backend Software

Engineer (APIs), Security Products Some of the largest sites on the internet trust Fastly to keep them safe.

The Security Products

Console team owns the public-facing interface they use to do it - configuring Next-Gen WAF, DDoS protection, Bot Management, and the products we’re building next. Customers deploy them during active attacks, automate them through Terraform and CI/CD, and build entire security workflows on top of them. When the threat landscape moves, our APIs are how customers move with it.

Design, ship, and own public-facing APIs and backend services in Go -from technical proposal & design docs through implementation, testing, and production rollout and on-call support. Use AI coding agents as part of your daily workflow. Partner with frontend engineers, product managers, and security researchers to ship the customer experience end-to-end.

Take ambiguous or broadly-scoped problems and turn them into well-defined technical plans that the team can execute on. Author design and architectural documents and use them to drive alignment across engineering and product teams Consider stability, performance,



and scalability in your designs and in the guidance you provide to the team Mentor and grow other engineers on the team through code review, pairing, and technical leadership Participate in an on-call rotation Hands-on experience designing and building reliable, large-scale backend systems - most Senior Engineers at Fastly have at least 5 years of relevant experience ~5+ years shipping production Go as your primary language. ~3+ years on public APIs with external consumers. You’ve shipped a breaking change to customers who’d already integrated against your API.

You drive projects, not just tasks. You’ve made one of these calls wrong in production and remember what it cost to clean up. ~ The customer hitting your endpoint at 3am, the support engineer debugging their escalation, the frontend teammate integrating against your contract. Testing and observability as subtraction, not addition.

Coding agents as a daily driver, not reluctantly. We’ll be super impressed if you have experience in any of these: This position will require you to be available during core business hours (Pacific Time) and occasional nights and weekends as required for on call support Work Location(s) & Travel Requirements: This position is open to the following preferred office locations: Fastly currently embraces a largely hybrid model for most roles which allows employees flexibility to split their time between the office and home.
