Application Developer (Identity & Cloud APIs)

Location: Remote

Contract: Initial contract until end of year (with potential extension)

Sector: Financial Services (Consultancy Client)

Role Overview

We are seeking a highly skilled Application Developer with strong expertise in identity API development, data ingestion and transformation, and event-driven architectures. This role will focus on building secure, scalable identity and access workflows within Google Cloud Platform (GCP), integrating identity services with custom APIs, Pub/Sub pipelines, and cloud-native applications.

You will work closely with technical leads, Cloud Security, DevOps, and Engineering teams to deliver robust IAM automation, identity lifecycle management, and secure service integrations supporting enterprise-scale cloud environments.

Key Responsibilities

Identity Orchestration

• Design and implement identity lifecycle flows (provisioning, de-provisioning, and orchestration)
• Integrate with Cloud Identity services, ServiceNow, and internal systems
• Build policy-based workflows for adaptive authentication and context-aware access (e.g. OPA)

API Development

• Design, develop, and secure RESTful APIs and backend services
• Integrate APIs with authentication services (token validation, session management, authorization)
• Develop internal SDKs, middleware, and shared libraries
• Ensure high standards of API security, performance, resilience, and observability

Event-Driven Architecture (Pub/Sub)

• Build API-to-Pub/Sub pipelines for asynchronous processing, including:
• Identity lifecycle automation
• Access review triggers
• Audit logging and event forwarding
• Security anomaly detection
• Develop Cloud Functions, Cloud Run services, or containerised workloads
• Implement robust event-processing patterns (retries, idempotency, DLQs, structured logging)

Automation & Infrastructure as Code

• Develop and maintain Terraform modules for IAM, APIs, Pub/Sub, and cloud resources
• Automate deployments via CI/CD pipelines
• Implement automated testing for IAM policies and API functionality

Support & Collaboration

• Troubleshoot identity, access, and API-related issues across distributed systems
• Provide guidance on secure API design and IAM best practices
• Support security audits, compliance activities, and incident investigations

Required Skills & Experience

Technical Skills

• Experience with identity orchestration platforms (e.g. Auth0 Actions, Okta Workflows, WorkOS, SlashID)
• Strong programming skills in Python, Go, or Node.js
• Experience building and deploying cloud-native APIs (Cloud Run, Cloud Functions, Kubernetes/GKE)
• Solid understanding of event-driven architectures and Pub/Sub systems
• Strong knowledge of OAuth2, OIDC, JWT, SAML, and identity federation
• Hands-on experience with Terraform or similar IaC tools
• Familiarity with API gateways, reverse proxies, or service mesh technologies

Soft Skills

• Strong analytical and problem-solving abilities
• Excellent communication and collaboration skills
• Proactive, ownership-driven mindset with a focus on security and quality
• Comfortable working in agile, fast-paced environments

Nice to Have

• Full-stack development experience (React)
• GCP certifications (Cloud Security Engineer or Cloud Architect)
• Experience with additional identity providers (Okta, Azure AD, Ping Identity)
• Familiarity with Kubernetes (RBAC, Workload Identity)
• Experience with secrets management tools (e.g. Secret Manager, Vault)
• Knowledge of compliance frameworks (SOC2, ISO 27001, PCI, HIPAA)

Why Apply?

• Work on cutting-edge identity and cloud security solutions
• Fully remote role with a high-impact financial services project
• Opportunity to shape scalable, enterprise-grade IAM and API architectures

If you’re an experienced developer with a passion for identity, security, and cloud-native engineering, we’d love to hear from you.
