Senior Backend Engineer

Senior Backend Engineer

Role Summary

As a Senior Backend Engineer, you will architect, design and deliver high-performance, reactive backend systems powering customer-facing retirement platforms. You will own critical services spanning authentication, orchestration, and API development while mentoring engineers and driving technical excellence. This role demands deep expertise in reactive programming, modern Java frameworks, Node.js middleware, and workflow orchestration in a regulated financial environment.

Key Responsibilities

• Architect, design, and implement reactive, non-blocking APIs using Java with Spring Boot (WebFlux), Quarkus, Micronaut, or Spark Java for high-throughput retirement account operations, in a TDD (Test Driven Development) iterative methodology
• Lead development of Node.js-based authentication, orchestration, and data aggregation layers handling complex multi-system integrations.
• Design and deliver production-grade BFF (Backend for Frontend) architectures in Node.js optimizing data delivery for Angular / React clients and mobile applications.
• Own Apache Camel integration implementations including enterprise integration patterns, Saga orchestration, and lightweight BPMN workflows for distributed retirement transactions.
• Architect and implement distributed transaction patterns using Saga compensating transactions across contribution, withdrawal, rollover, and compliance workflows.
• Drive GraphQL API design including schema evolution, query optimization, batching strategies, and resolver performance tuning for complex domain aggregations.
• Lead ORM strategy and implementation using Hibernate, JPA, or TypeORM with focus on performance optimization, caching strategies, and database query tuning.
• Establish reactive programming patterns using Project Reactor, RxJava, or reactive streams for high-concurrency, low-latency financial operations.
• Design resilient system architectures incorporating circuit breakers, bulkheads, rate limiting, and fallback mechanisms for third-party integrations.
• Collaborate with architects and product leaders to define technical roadmaps, API contracts, and domain boundaries for retirement platform evolution.
• Mentor junior and mid-level engineers through code reviews, architecture discussions, and technical guidance on best practices.
• Drive quality through comprehensive testing strategies including unit, integration, contract testing, and chaos engineering principles.
• Lead incident response, root cause analysis, and implement preventive measures for production systems.
• Champion engineering excellence through establishing coding standards, architectural patterns, and observability practices.
