Job summary

Michael Page is partnering with a Mumbai-based financial services tech firm to hire a Backend Engineer for Platform Engineering. You will own core platform services and drive API gateway and service mesh implementations to support a twelve-squad landscape.

You will work on AI-native tooling, observability, and contract testing while mentoring junior engineers in a fast‑growing environment.

Qualifications

• Strong experience in backend engineering with Java/Spring Boot and microservices.
• Experience designing REST APIs with OpenAPI and event-driven architectures.
• Skilled in SDK design, distributed systems patterns and scalable platform services.
• Familiarity with IAM, OAuth2, RBAC and feature flag systems.
• Experience with API gateways and service meshes (Istio/Linkerd).
• Knowledge of OpenTelemetry, tracing, and contract testing (Pact).
• Experience with messaging (SQS, Kafka) and resilient systems.

Responsibilities

• Build and maintain shared backend platform services (IAM/RBAC SDK, AI SDK wrapper, notification service, event bus, feature flags).
• Own IAM/RBAC SDK implementation translating design into production-ready code.
• Build AI SDK integration layer for LLM APIs with rate limits, cost tracking, and PII redaction.
• Design and implement shared event bus patterns across services using SQS or Kafka.
• Write platform SDK docs and onboarding guides for squads.

Job description

• Embrace a high-growth, high-impact environment
• Tackle real-world challenges

About Our Client

The hiring company is a small-sized organization within the financial services and fund management industries. They are dedicated to delivering innovative solutions and leveraging technology to drive business growth and operational efficiency.

Job Description

Platform Service Development

• Build and maintain the shared backend platform services - the IAM/RBAC SDK, the AI SDK wrapper, the notification service, the event bus, and the feature flag system that every squad consumes
• Own the IAM/RBAC SDK implementation - translating the Cloud-Native Platform Architect's design into a production-ready SDK that twelve squads can integrate with confidence
• Build the AI SDK integration layer - the secure, consistent interface for squads to call LLM APIs with rate limiting, cost tracking, PII redaction, and fallback handling built in
• Design and implement the shared event bus patterns - how domain events are published, subscribed to, and replayed across services using SQS or Kafka
• Write the platform SDK documentation and integration guides that product squad engineers use to onboard themselves without requiring Phoenix involvement

API Gateway & Service Mesh

• Own the API gateway implementation - routing configuration, authentication enforcement, rate limiting rules, and the observability instrumentation that feeds into the platform monitoring stack
• Implement service mesh configuration for inter-service communication - mTLS, circuit breakers, retry policies, and traffic management for the twelve-service landscape
• Define and enforce API standards in collaboration with the Cloud-Native Platform Architect - contract-first development, OpenAPI spec, versioning, and backward compatibility discipline
• Build the API testing infrastructure - consumer-driven contract tests that catch breaking changes before deployment and give squads confidence in the API gateway configuration

AI-Native Platform Engineering

• Use Cursor and Claude as primary development tools - the Phoenix engineering standard is AI-augmented development; all code, tests, and documentation are AI-assisted
• Build the n8n and AppSmith integration hooks - the platform-level API endpoints and webhooks that allow Rangers' automations to interact safely with platform services
• Implement observability instrumentation across platform services - distributed tracing (OpenTelemetry), structured logging, and metrics that give the organisation visibility into platform health

Quality, Reliability & Mentoring

• Set and maintain code quality standards within Phoenix - code review, refactoring discipline, test coverage, and the mentoring of Intermediate and Associate engineers
• Own platform service reliability - SLO monitoring, incident response, and the postmortem process when platform services affect product squad delivery
• Contribute to the Platform Guild - share platform engineering knowledge, present implementation decisions, and participate in cross-squad technical discussions
