Application Developer
About this role
Anticipated Contract End Date/Length: 6 months contract Work Setup: Hybrid (3 days per week in office, mandatory) Our client in the Information Technology and Services industry is looking for a highly skilled Application Developer with strong expertise in identity API development, data ingestion and transformation, and event-driven (Pub/Sub) architectures. The role focuses on building secure, scalable identity and access workflows across Google Cloud Platform, integrating identity services with custom APIs, Pub/Sub pipelines, and cloud-native applications.
Collaborate closely with Tech Leads, Cloud Security, DevOps, and Application Engineering teams to design and implement robust IAM automation, identity lifecycle workflows, and secure service integrations supporting enterprise-level cloud and Identity operations. What you will do: Design and implement identity flows for provisioning, de-provisioning, and orchestration of identity lifecycle events. Integrate Cloud Identity Services, ServiceNow, and internal services to streamline and orchestrate identity provisioning and lifecycle management.
Build policy-based orchestration workflows for adaptive authentication and context-aware access using industry standards such as OPA. Design, build, and secure RESTful APIs and backend services supporting identity, provisioning, and governance workflows. Integrate APIs with authentication services for token validation, user sessions, and application-level authorization. Build and document internal SDKs, middleware, and shared libraries to maintain consistent IAM logic across services.
Ensure API security, performance, reliability, resilience, and observability. Develop API-to-Pub/Sub pipelines for asynchronous workflows, including automated identity lifecycle tasks, access review event triggers, logging and audit forwarding, and security anomaly detection. Build Cloud Functions, Cloud Run microservices, or containerized services to process Pub/Sub messages. Implement robust event-processing patterns, including retries, idempotency, dead-letter queues (DLQs), and structured logging.
Build and maintain Terraform modules for IAM, API services, Pub/Sub topics, workloads, and permissions. Automate deployment and validation of identity and access configurations through CI/CD pipelines. Implement automated testing for IAM policies and API behaviour. Troubleshoot identity, access, and API workflow issues across distributed systems. Provide technical guidance to engineering teams on secure API design, IAM best practices, and identity workflows.
