Customer Support Engineer
The Fastly Edge Cloud Platform powers the best of the internet, and our Customer Support Engineering (CSE) — a key function within our broader Customer Experience organization — ensures customer experiences are a success through a transparent and timely support management system. This opening is for a Customer Support Engineer, Tier I, an entry-level position within our three-tiered team (Tier I, Tier II, and Tier III) that offers multiple opportunities for future career development within Fastly.
Fastly is seeking a technical expert for customers using our delivery and compute platforms. This role requires a strong understanding of internet protocols and the ability to advise on code updates that modify traffic at the network edge.

What You'll Do:
Programmable edge troubleshooting: Review our customer configurations and debug VCL logic and Compute (Wasm) applications, optimizing cache hit ratios, and manipulating HTTP headers.

Omnichannel customer support: Resolve technical inquiries across email, chat (powered by Slack), and portal engagements, including live triage sessions over video or telephone conferences, with a target first response time (FRT) Service Level Agreement (SLA).
Collaborative escalation: Recognize when to ask for help. You will learn to properly escalate support cases to higher-tier teams to advocate for a timely resolution for our customers.
Live event monitoring and on-call coverage: Monitor metrics during large network events and proactively report degradation to our customers. This role includes an on-call rotation managed by PagerDuty, covering weekends, select after-hours, and corporate holidays (which includes additional holiday pay).
What We're Looking For:
Experience: 2-4 years in a technical support, sysadmin, or network-focused role.
Protocol proficiency: Demonstrated understanding of HTTP/s, TCP/IP, TLS, and DNS (must explain delivering a webpage in under 200 milliseconds).
Program Language Proficiency: Recent coding bootcamp graduates with a focus in VCL, Python, Ruby/Go, JavaScript, Rust, etc. with a demonstrated entry to moderate level of efficiency.
UI and API literacy: Proficiency navigating modern SaaS control panels and RESTful APIs via CLI.
Customer-facing business acumen: Strong written communication skills and analytical skills with experience supporting customers via email, chat, ticketing system or phone
Triage proficiency: Demonstrated understanding of network related telemetry and diagnostic tools
Industry exposure: Demonstrated understanding of networking, including, BGP, internet routing, and the difference between transit and peering
