Role Summary
We are looking for a highly skilled Application Developer with strong expertise in identity API development, data ingestion and transformation, and event-driven (Pub/Sub) architectures. This 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. You will 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 that support enterprise-level cloud and Identity operations.
Key Responsibilities
Identity Orchestration
- Design and implement identity flows for provisioning, de-provisioning and orchestration of identity lifecycle events.
- Integrate with Cloud Identity Services, ServiceNow, and internal services to streamline / orchestrate identity provisioning and identity lifecycle management.
- Build policy-based orchestration workflows for adaptive authentication and context-aware access using industry standards (like OPA).

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
API Development
- Design, build, and secure RESTful APIs and backend services supporting identity, provisioning, and governance workflows.
- Integrate APIs with our new authentication service for token validation, user sessions, and application-level authorization.
- Build and document internal SDKs, middleware, and shared libraries for consistent IAM logic across services.
- Ensure API security, performance, reliability, resilience, and observability.
API-to-Pub/Sub Event Processing
- Develop pipelines where API events publish to Pub/Sub for asynchronous workflows such as:
- automated identity lifecycle tasks
- access review event triggers
- logging and audit forwarding
- 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, DLQs, and structured logging.
Automation & Infrastructure as Code
- Build and maintain Terraform modules for IAM, API services, Pub/Sub topics, workloads, and permissions.
- Automate deployment and validation of identity and access configurations via CI/CD pipelines.
- Implement automated testing for IAM policies and API behaviour.
