Backed by CRV.
About the role
We're hiring as the API surface scales for new product launches and a growing developer ecosystem. You'll be one of the engineers shaping what that surface looks like for the next several years. We’re always looking for humble, sharp, and creative folks to join the Fastly team. If you think you might be a fit please apply! A fully completed application and resume or CV are required when applying.
What they're looking for
- 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've written a deprecation notice that actually went out
- You drive projects, not just tasks. You've owned a multi-week effort end-to-end: design doc through post-launch
- Good judgement on RESTful API design: resource modeling, versioning, idempotency, error semantics, pagination, OpenAPI. You've made one of these calls wrong in production and remember what it cost to clean up
- Testing and observability as subtraction, not addition. You can name a metric you added that paid off — and one you'd delete now
