Principal Software Engineer - Network Telemetry 

Fastly has a globally distributed platform with a well connected network to peers and transits. Our servers generate a massive amount of telemetry which is enriched by ingress and egress traffic flow information. With this volume of data comes some interesting challenges around noise, multiple interpretation of signals and being able to tell cause and effect apart. 

We are always interested in generating clean signals from our network telemetry so they are always  actionable. And we look for ways we can create closed feedback loops to build self-healing systems.  

We are looking for a technical leader with experience in designing, building and operating distributed systems that are scalable, fault tolerant and easy to manage. The pipelines you will work with are near realtime telemetry and some of them are extremely  latency sensitive as they are part of traffic engineering controller inputs. You will also be responsible for running complex troubleshooting that requires new telemetry to be introduced or when the issue spans multiple parts of the stack.

This role will be in our network systems group. You can expect complex but fun challenges in near-real-time analysis and distributed systems while working closely with network engineers and kernel engineers.

What You’ll Do

• Lead multi-functional initiatives, collaborate and gather requirements from cross functional teams and translate them into software features that can increase automation capabilities 
• Design, implement and operate distributed control systems that collect and aggregate large amounts of data to manage network services and configuration
• Be the point person to run complex troubleshooting when the problem spans multiple complex sub systems
• Consider scalability, security, performance and reliability in the design of the applications you support
• Build relationships with other teams and act as technical lead in conversations inside and outside the team
• Help identify new areas of opportunity in existing products, and draft solutions to support those efforts
• Mentor junior engineers and give them opportunities to grow inside your projects

What We’re Looking For

• You have a minimum of 8 years of experience building or operating networking/distributed/cloud systems
• You have at least 8 years of hands on experience with design and development of software components on Unix/Linux platforms
• Experience with projects related to low-latency data collection and analysis
• You have at least 5 years of experience in writing elegant and maintainable Rust, Python and/or Go code

We value a variety of voices, so this is not a laundry list. It would be an added bonus if you have experience in ANY of these:

• Experience with GCP (Google Cloud Platform) or AWS infrastructure
• Implementation skills with network data structures such as graphs, tries, etc.
• Experience with Machine Learning & Analytical tools
• Experience with infrastructure as code systems like terraform and Kubernetes
• Familiarity with network protocols such as DNS and TCP
