# Jess Yuen > Staff Software Engineer at Reddit Location: Seattle, Washington, United States Profile: https://flows.cv/jessyuen I'm a infrastructure engineer that cares about all distributed system problems related to reliability, scalability, efficiency, and improving the developer experience. ## Work Experience ### Staff Software Engineer @ Reddit, Inc. Jan 2024 – Present | Greater Seattle Area Compute! ### Staff Software Engineer, Founding Team @ Moment Jan 2021 – Jan 2023 | Seattle, Washington, United States Moment (moment.dev) is a early stage startup aimed at improving the developer experience with interactive docs. As their first full-time engineer, my responsibilities were broad; some of them include: - Founded and tech lead for Atlas, an authenticating proxy for safely and securely making requests to private resources in customer networks. The Atlas server is managed by customers and runs in their cluster. Atlas never exposes secrets or credentials to a client. Atlas is used to add SSO access to internal data sources, build internal web portals, and build protected command-line tools. - Infrastructure provisioning and maintenance; setting up our dev (minikube, docker compose, kustomize), staging and production environments (AWS EKS and ECS Fargate, NLB/ALB, Envoy, etc.), automating releases using Pulumi and Github Actions, and setting up monitoring and pages in Datadog. Ensuring reliability at scale. - Working extensively across our stack including the frontend web application (React/Redux/Vercel), backend services (Go/Dynamodb/Redis), CI/CD (Pulumi/Github Actions/Docker), and compute and networking infrastructure (AWS/Kubernetes) to deliver on large projects. - Working closely with our designer and product manager and engaging directly with customers to design solutions for open-ended problems like service catalog, onboarding experience, collaborative editing and autosave, customer test kubernetes clusters, etc. - Roadmap planning, on-call rotation and responsibilities design, designing interview questions and interviewing, helping build our engineering culture, and mentoring. ### Networking - Tech Driver | Staff Engineer @ Lyft Jan 2019 – Jan 2021 | Greater Seattle Area Lyft had official Tech Driver titles. The designation was tied to my responsibilities of leading Lyft’s Networking team of ten people. During my tenure, I: - Operated our Envoy based service mesh and edge proxy on our Kubernetes and legacy infrastructure, responsible for all of Lyft’s server-side web & mobile traffic. This included migrating legacy systems to Kubernetes and operating the proxy in that environment. - Provisioned data planes, control planes, and setup of server-side streaming using Envoy’s xDS protocol. - Worked side-by-side with my manager and closely with infrastructure directors to create Roadmap and OKRs for the Networking team and influence the Roadmap of neighboring teams across infrastructure. - Designed systems to increase Networking reliability, i.e. Request percentage-weighted load balancing system for Lyft’s Network traffic. - Contributed to open source code, open source community management and maintainer in the Envoy ecosystem, and gave conference talks regarding Lyft’s engineering efforts, ex: Envoycon 2020. - Championed best practices for building scalable and reliable services. - Conducted remediation and root cause analysis on production incidents for our tier 0 services. - Mentored new hires and other engineers across teams, and conducted technical interviews ### Capacity - Senior Software Engineer @ Lyft Jan 2019 – Jan 2019 | Greater Seattle Area Infrastructure spend and budgets. ### CI/CD - Senior Software Engineer @ Lyft Jan 2018 – Jan 2019 | Greater Seattle Area Infrastructure Automation and CI/CD on Kubernetes. ### Systems Software Engineer @ Heptio Jan 2017 – Jan 2018 | Greater Seattle Area Heptio was a startup launched by the founders of the Kubernetes project while at Google, to help advance the open Kubernetes ecosystem and bring Kubernetes to enterprise. I worked in a distributed team and contributed primarily as one of the lead developers to an open source community project, ksonnet; a configuration management tool for Kubernetes. - Authored and reviewed technical design documents, as well as initiated and attended engineering product review meetings to help drive overall project direction. - Led implementation and design for key features, such as adding support for ksonnet environments; a feature that allows users to easily deploy Kubernetes configuration manifests to multiple clusters. - Wrote integration tests and configured automated test pipelines to allow for continuous delivery and continuous integration of our product revisions. - Integration of our internal infrastructure with ksonnet to deploy and manage Kubernetes resources. - Engaged with the open source community through GitHub, Slack channels, and email groups. ### Software Engineer II @ Twitter Jan 2016 – Jan 2017 | Canada While at Twitter, I worked on the Cloud Infrastructure team to design and develop tools to simplify the service lifecycle management process in creating, managing, and utilizing service resources on Twitter’s multi-tenant infrastructure. - Led the technical design and implementation for Service Identity, a key component in enabling service-to-service authentication for thousands of Twitter’s microservices. - Contributed in the design and development of Chargeback, a web service that allowed resource usage metering of physical servers and multi-tenant services (Mesos / Aurora, Hadoop, etc.) on a per-cost-center, per-team basis, with a unified pricing model and pricing methodologies similar to public clouds. It led to company-wide infrastructure efficiency and optimization programs. - Cross-team collaboration with Technical Project Managers, Software Engineers, and Product Managers in the Twitter CA (secrets and certificate authorization), Roster (team and department hierarchy), Traffic (network), and various other Infrastructure teams to drive initiatives and design in service-to-service authentication. - Technical speaker at Twitter’s Compute Event on Chargeback for Multi-tenant Infrastructure, with approximately 200 attendees, and gave various other brown bag presentations internally across organizations. - Conducting over the phone and onsite interviews for potential engineering candidates across the spectrum of seniority. ### Software Engineer @ Twitter Jan 2015 – Jan 2016 | San Francisco Bay Area Platform Engineering - Cloud Infrastructure. ### Open Source Developer @ Review Board Jan 2015 – Jan 2015 | Canada Review Board (https://github.com/reviewboard) is a widely used open source tool for code review. I worked in a distributed team across Canada and the US to create Review Board Gateway (https://github.com/reviewboard/rb-gateway), a lightweight hosting service that allows users to conveniently connect their remote SCM repositories to Review Board. I also integrated rb-gateway with Review Board through a set of RESTful APIs, allowing Review Board to efficiently perform functionalities such as file retrieval, file existence verification, and acquisition of branch and commit information on rb-gateway hosted repositories. ### Software Developer @ Nakina Systems (Acquired by Nokia) Jan 2014 – Jan 2014 | Ottawa, Canada Area Development of multi‑tiered network management systems. Created, maintained, and delivered a sizeable amount of features for our main product line primarily using Enterprise Java.
