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. Our platform does not stop at application code. It also creates and manages the secure cloud infrastructure in which AI-agent systems are deployed and operated. That makes infrastructure design a core product capability, not a supporting function. </span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt;">This role will lead the design and implementation of the multi-cloud platform that supports customer environments, secure deployment patterns, cloud networking, and production guardrails. It is a hands-on principal engineering role for someone who wants to build the underlying infrastructure that makes secure AI-agent deployment possible at scale.&nbsp;</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"> <ul> <li>Design and build backend services and APIs for onboarding, policy management, audit, environment inventory, and platform operations.</li> <li>Develop reliable and well-structured REST and gRPC APIs that power the management layer of a secure AI-agent platform.</li> <li>Own data models, service contracts, validation logic, and service-to-service interactions for core platform workflows.</li> <li>Work on integrations with cloud services, identity systems, and platform components that support secure runtime environments.</li> <li>Improve observability, error handling, test coverage, deployment safety, and production support for backend services.</li> <li>Collaborate with frontend, security, and infrastructure engineers to turn complex platform requirements into clear, maintainable backend implementations.</li> <li>Build services that will directly shape how customers manage AI agents in production, and support those services in production yourself.</li> </ul> </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;"> <ul> <li>8-12 years of backend engineering experience.</li> <li>Strong hands-on experience in TypeScript/Node.js, Go, Java, or Python — ability to work across languages as the stack evolves.</li> <li>Strong experience designing and building REST and gRPC APIs, service integrations, and backend systems for production use.</li> <li>Good understanding of distributed systems concerns such as retries, idempotency, failure handling, observability, and release safety.</li> <li>Strong experience with relational databases (PostgreSQL, MySQL) and backend data modeling.
