Job description

Performance Engineer

Experience - 6+ years

Location - Pune (Hybrid)

About the role -

As a Senior Performance Engineer, you will be responsible for designing and executing performance workloads (baseline, peak, burst/stress, endurance/soak, dependency-latency, event-backlog, and batch-volume tests) across Widget/token initialization, Benefit Eligibility, Airports API, Lounge/Fast Track fulfillment, and critical vendor adapters. You will build a reusable performance-testing suite, capture throughput, latency percentiles (p50/p90/p95/p99), error/retry rates, and resource/telemetry metrics, and establish approved performance baselines using production evidence or SLOs.

Working within an Agile environment, you will collaborate with the QE Platform/Test Lead, Product Management, Engineering, and Quality Engineering teams to integrate performance gates into the release process. In addition, you will take ownership of the team's performance strategy, analyze saturation points and recovery behavior, mentor engineers on performance practices, and continuously improve efficiency and engineering standards.

Skills/Requirements

• Strong hands-on experience in Java, J2EE, Spring, and Spring Boot
• Experience building and consuming REST APIs and Web Services
• Hands-on experience with performance-testing tools (e.g., JMeter, Gatling, k6) and API Automation
• Experience designing performance workloads, baselines, and automation strategies
• Strong understanding of software engineering principles, design patterns, and SDLC
• Experience with CI/CD, Git, code reviews, and Agile/Scrum methodologies
• Ability to take ownership, drive initiatives independently, and deliver results
• Experience troubleshooting production issues, root-cause analysis, and production support
• Hands-on experience developing solutions and building AI-powered agents using tools such as GitHub Copilot, Microsoft 365 Copilot, Claude, and similar AI platforms to accelerate software development, testing, troubleshooting, automation, and technical documentation.
• Strong communication, collaboration, and mentoring skills
• High degree of initiative, self-motivation, and continuous learning mindset

In addition, the following is also highly desirable:

• Performance and security testing
• Continuous Integration and Continuous Delivery
• Microservices and cloud-native application architecture
• Event-driven and batch-processing performance analysis (Kafka/Axon, BPS Batch)
• Payments, Benefits, or FinTech domain experience

Education

Bachelor's degree in Information Technology, Computer Science, Information Systems, Engineering, or an equivalent combination of relevant education and experience.
