We believe that the way people interact with their finances will drastically improve in the next few years. We’re dedicated to empowering this transformation by building the tools and experiences that thousands of developers use to create their own products. Plaid powers the tools millions of people rely on to live a healthier financial life. We work with thousands of companies like Venmo, SoFi, several of the Fortune 500, and many of the largest banks to make it easy for people to connect their financial accounts to the apps and services they want to use. Plaid’s network covers 12,000 financial institutions across the US, Canada, UK and Europe. Founded in 2013, the company is headquartered in San Francisco with offices in New York, Seattle, Washington D.C., Raleigh, London, and Amsterdam.
As an Infrastructure Engineer on Network Infrastructure, you'll own large parts of the network that every Plaid product depends on. You'll plan and lead changes that touch the whole company, like upgrading our service mesh or modernizing older parts of our cloud network, and deliver them safely without disrupting customers. You'll build tools that let product engineers move faster on their own, help strengthen the security and compliance boundaries in our network, and dig into hard problems when something goes wrong. The team is small and new, so you'll have a real voice in its technical direction, with a clear path toward Staff-level scope.
Responsibilities
Lead company-wide network changes, such as service mesh upgrades and gateway migrations, using staged rollouts so customers see no disruption.
Simplify and modernize our cloud network, reducing risk and making it easier to operate.
Build self-serve tools in Go and Terraform that let product engineers expose, route and secure their services independently.
Help set stronger security and compliance boundaries in our network without slowing developers down.
Debug complex network issues and turn what you learn into better alerts, dashboards and guardrails.
Take part in on-call, lead incident response for network issues, and drive the follow-up fixes.
Qualifications
Experience running production infrastructure at scale, in infrastructure, SRE or network engineering
A solid understanding of networking fundamentals: TCP/IP, DNS, TLS, HTTP and load balancing
Hands-on experience with Kubernetes networking, such as a CNI, a service mesh or ingress
Experience with cloud networking, ideally on AWS
Ability to write code in Go or Python
A track record of making large production changes safely, with a plan for rollback
Nice-to-Have:
Production experience with Istio, Envoy or Cilium
