Platform Architect - Banking

Job description

About us EggAI is a fast-growing AI consulting and development startup. We build agentic AI solutions for enterprise clients. We are growing in several European markets. The role You will own the design of a shared AI platform for our clients. The platform has two parts. An AI Control Plane governs what agents may do, through identity and delegated permissions, policy enforcement, approvals, budgets and durable audit records. A managed AI Runtime is where the agents run. Both integrate with the client's identity, security, delivery and audit services. You will set the architecture, define how services and controls fit together, and make sure what the team builds is sound, assured and ready for production. The role reaches across engineering, security, audit, risk and the client's architecture function.

Decide where each security and policy control is enforced: in the gateway, the control plane, the runtime or the client's own services. - Keep the design record. Write architecture decision records (ADRs) and record every deviation from the client's standards or our reference designs for a client decision. - Take designs through the client's architecture and risk forums. Secure approvals in time for dependent work, so that design precedes implementation. - Lead design and quality review across all platform services. Review engineers' changes, cross-service tests and fault exercises with the CTO. - Define how the architecture will be proven. Agree acceptance criteria with engineers and client control owners for each interface, control and infrastructure contract, including behaviour when a dependency fails, and review the test evidence showing they are met. - Hold…
