Advises immediate management on project-level issues Guides junior engineers Operates with little day-to-day supervision, making technical decisions based on knowledge of internal conventions and industry best practices Applies knowledge of technical best practices in making decisions Design, build, and operate cloud network and routing infrastructure across our AWS environment, including VPCs, transit gateways, load balancers, and service mesh Build, tune, and operate our cloud CDN and edge delivery using AWS CloudFront to improve performance, availability, and global reach Configure and maintain WAF rules and other edge security controls to protect services from DDoS, bot, and application-layer attacks Operate and extend Envoy- and Contour-based ingress and service mesh for both north-south and east-west traffic Configure and maintain nginx-based reverse proxy and load-balancing services Partner with SRE, security, and product engineering teams across the Cloud Platform & Infrastructure org on shared networking and edge initiatives Troubleshoot network incidents such as latency, packet loss, routing failures, and TLS/certificate issues; identify root cause and implement fixes and preventive measures Develop and improve infrastructure-as-code (Terraform) to manage networking and routing configuration Participate in an on-call rotation supporting network, routing, and edge services Document designs, runbooks, and operational best practices 8+ years relevant experience and a Bachelor's degree OR Any equivalent combination of education and experience. 3+ years relevant experience and a Bachelor's degree OR Any equivalent combination of education and experience. Engineering in Cloud Platform & Infrastructure Our Cloud Platform & Infrastructure organization builds and operates the foundational services that power Venmo's platform: compute, networking, routing, observability, and developer platform capabilities used by every product team at Venmo. We believe great infrastructure should be invisible to the teams who rely on it; fast, secure, and reliable by default. We partner closely with SRE, security, and product engineering teams to build automated, self-service systems at scale, and we hold ourselves to a high bar for engineering rigor and operational excellence. Cloud Network & Routing Engineer Our Cloud Network & Routing team owns the network & routing layers that connect Venmo's applications to the internet and to each other: CDN, proxy, web application firewall and security, ingress and routing, and internal traffic management across our AWS environment. We work hand-in-hand with the rest of the Cloud Platform & Infrastructure org, including compute, storage, SRE, and security teams, to make sure traffic is fast, secure, and reliable at every hop. As a Senior Software Engineer, you will deliver complete solutions spanning all phases of the SDLC for our network and routing systems. You are a hands-on contributor who mentors other engineers and product owners, drives best practices, and operates with a high degree of independence while being accountable for results.
