Role Overview

The selected candidate will be responsible for leading the backend engineering strategy for the Fundmaster Modernization program. The role involves transforming complex legacy capabilities into modern, scalable, resilient, and supportable Java services.

The candidate will be expected to work hands-on across architecture, design, development, testing, deployment, troubleshooting, and production support, while also providing technical direction and mentoring to the engineering team.

Key Responsibilities

Lead the architecture, design, development, testing, deployment, and production support of enterprise-grade Java backend services.

Define and enforce engineering standards around API design, service boundaries, coding practices, secure development, automated testing, logging, exception handling, and operational readiness.

Design and implement appropriate synchronous, asynchronous, and reactive processing patterns based on business requirements.

Conduct and lead architecture reviews and code reviews.

Ensure non-functional requirements related to performance, scalability, reliability, resilience, security, and observability are addressed.

Troubleshoot complex production and application performance issues, including:

Memory leaks

Thread contention

Connection-pool exhaustion

High CPU utilization

API latency

Slow SQL queries

JVM and service scalability issues

Analyze heap dumps, thread dumps, GC logs, JVM metrics, database execution plans, and connection-pool behaviour.

Lead root-cause analysis (RCA) for critical incidents and drive sustainable corrective and preventive actions.

Mentor engineers and provide technical guidance across development and delivery.

Communicate delivery status, technical risks, dependencies, impact, mitigation plans, and key decisions to stakeholders and management.
