Software Engineer

Key Responsibilities

• Design, develop, and execute performance testing strategies for digital banking applications, mobile banking, internet banking, APIs, and microservices.
• Define and validate Non-Functional Requirements (NFRs) including response time, throughput, scalability, concurrency, availability, and resilience.
• Develop performance test scripts and workloads using JMeter, LoadRunner, NeoLoad, or equivalent tools.
• Execute load, stress, spike, endurance, failover, and capacity testing across applications and APIs.
• Analyze application performance bottlenecks across UI, API Gateway, microservices, middleware, databases, and infrastructure layers.
• Monitor applications using observability and APM tools to identify root causes of performance degradation.
• Collaborate with development, architecture, DevOps, SRE, infrastructure, and database teams to optimise platform performance.
• Validate performance of mobile banking, internet banking, onboarding journeys, payments, and corporate banking services under peak load conditions.
• Produce detailed performance reports, recommendations, and executive summaries for release approvals and production readiness reviews.
• Support capacity planning, volumetric modelling, and performance benchmarking activities.
