Software Engineer Distributed Systems (Service Mesh and Load Balancing)

Salesforce

Dublin, Ireland

Join a team building the Service Mesh and Ingress Gateway load balancing and proxy platform.

The Microservices Platform Service Mesh team is building a highly scalable and distributed load balancing and gateway service to front all customer traffic coming into Salesforce. We provide simple declarative interfaces for L4/L7 load balancing, TLS termination, end-to-end encryption, along with support for richer traffic policies such as blue/green deployments, access control, etc. We are looking for people who can drive the design and implementation of the next generation Ingress Gateway control plane and data plane. We intend to transform our current software stack to adopt more cloud native primitives to build a more reliable, scalable, and feature-rich service mesh. Our software stack is based on leading edge open source software like Envoy, Nginx for dataplane and Istio, Consul, etc. for control plane. The opportunities to enhance the capabilities of the OSS software and contribute back to the community are immense. The team had already made active upstream contributions to the Envoy project. We intend to transform the way our north-south traffic is secured, load balanced and proxied before entering our core service mesh. We are looking to add experienced distributed systems engineers who are passionate, hungry for new challenges, can step up and own big chunks of that vision.
