How You'll Make an Impact:
As a Lead TLS & PKI Engineer on the Solutions Enablement team, you will establish deep technical leadership for Epsilon's public and private PKI, TLS, and certificate lifecycle capabilities—bringing protocol-level expertise the team needs to move from reactive certificate operations toward automated, observable,



and standards driven trust services.
You understand the shapes and forms TLS takes in enterprise environments—server authentication, client authentication (mTLS), private PKI, public CA–issued certificates, and cloud-managed trust—and when each pattern applies. You partner with Security on trust policy, with Network on edge and load-balancer consumption, and with Cloud, Platform, and Application teams on how certificates are issued, renewed, inventoried, and deployed across AWS, Azure, and GCP.
You will drive incremental maturity in certificate inventory, renewal automation, trust-chain management, TLS monitoring, and industry-aligned practices (including shorter public certificate lifetimes and reduced reliance on manual dispensing). You mentor engineers on TLS fundamentals, unblock complex handshake and chain-validation issues, and translate technical depth into momentum—documented patterns, automation, and opera
