Digital S/W Eng Sr Analyst - C12 - PUNE

The Digital S/W Engineer Sr Analyst Shape, build, and govern high-impact API solutions as a Senior Systems Engineer, sitting at the intersection of hands-on Apigee development and API design leadership within Citi's Digital Engineering organization. In this hybrid technical role, you will both develop and configure production API solutions on Google Apigee and lead the design and specification of API interfaces and integration patterns — owning mid-size features end-to-end from architecture through deployment, while contributing to larger platform initiatives. You will be equally comfortable configuring Apigee proxies and policies as you are producing API design artefacts, leading design reviews, and governing integration standards. This role sits within Citi's Wealth Digital engineering team, where your contributions will directly shape API quality, security posture, and delivery outcomes at scale. Responsibilities Apigee ● Design and configure API proxies on Google Apigee, including proxy configurations, flow definitions, route rules, and target endpoint setup. ● Define and maintain Apigee policies — including traffic management (quota, spike arrest, rate limiting), mediation (JSON-to-XML, message transformation), and security (OAuth, API key validation, JWT verification) policies. ● Implement OAuth 2.0 and OpenID Connect (OIDC) authorization flows natively within Apigee, including authorization code, client credentials, and token introspection patterns. ● Configure and manage Apigee environments, API products, developer portals, and monetization configurations in line with platform governance standards. ● Integrate Apigee with backend services, identity providers, and downstream systems through secure, performant target configurations. API Design & Governance ● Lead the design and specification of RESTful APIs, producing OpenAPI/Swagger documentation, API contracts, and integration specifications that engineering teams implement against. ● Apply Financial-grade API (FAPI) security profiles in both API design specifications and Apigee proxy configurations to protect sensitive financial data exchanges. ● Apply knowledge of Open Banking regulations (e.g., PSD2, CDR, Section 1033) to design and build compliant, interoperable API interfaces on the Apigee platform. ● Define and enforce API design standards and governance guidelines, governing APIGEE Products and Proxies ,including naming conventions, versioning strategies, error response schemas, and pagination patterns. ● Facilitate and lead API design reviews and architecture walkthroughs, providing well-reasoned recommendations that guide engineering implementation decisions. ● Produce technical diagrams — sequence diagrams, flow diagrams, and system context maps — to document API behavior, data flows, Apigee policy execution, and integration touchpoints.
