As AI agents move from simple chatbots to autonomous workloads with access to sensitive enterprise data, the industry lacks a standard for Identity, Authentication, and Governance. This role focuses on the runtime software that protects and governs how AI-agent systems communicate in production. You will work close to application traffic, secure service communication, policy enforcement, and runtime integrations across cloud-native and external environments. The work sits at the intersection of networking, security, and distributed systems. It is a strong fit for someone with deep Go and networking experience who wants to build the software that makes AI-agent execution safer, more controllable, and more production-ready.</span></p> <p>&nbsp;</p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"><strong>What you will do</strong></span></p> <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div id="page-2" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-1">Build runtime software that handles secure communication, traffic control, policy enforcement, and service protection for AI-agent systems.</div> </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div id="page-2" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-1">Work on network-facing components such as application proxies, traffic inspection layers, secure communication libraries, and runtime security services.</div> </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div id="page-2" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-1">Implement and improve HTTP, TLS, certificate handling, request inspection, authorization integration, and performance-sensitive runtime logic.</div> <div id="page-3" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-2"></div> </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div id="page-3" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-2">Partner with identity and platform engineers to connect runtime systems with authentication, authorization, audit, and cloud deployment workflows.</div> </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div id="page-3" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-2">Improve runtime reliability, observability, performance, and operability in production environments.</div> </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div id="page-3" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-2">Help define how secure runtime controls should work for modern AI-agent systems across internal and external execution environments.</div> </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div id="page-3" class="_kqswh2mm _bfhku67f _18u01wug _2hwx1wug" data-testid="page-2">Support production incidents and continuously improve the safety and supportability of runtime systems.</div> </li> </ul> <p>&nbsp;</p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"><strong>What you will have</strong></span></p> <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt;">8+ years of software engineering experience. </span></li> <li style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt;">Strong hands-on experience in Go.
