Technical Lead

Overview:

Technical Lead – Performance Engineering & Testing

Location: Bangalore | Department: Engineering | Employment Type: Full-Time

About the Role

We are looking for a seasoned Technical Lead in Performance Engineering to drive the performance, scalability and efficiency of our Java-based enterprise applications. In this role, you will own the end-to-end performance lifecycle – from design reviews and test strategy through production monitoring – ensuring our platforms meet the highest standards of throughput, latency and resilience.

Key Responsibilities

Performance Engineering & Testing

Lead performance engineering initiatives across Java-based applications, defining test strategies, frameworks and tooling standards

Design, build and execute load, stress, soak and scalability tests using tools such as JMeter, Gatling or Locust

Analyze JVM internals – heap profiling, garbage collection tuning, thread contention – to identify and resolve bottlenecks

Collaborate with development teams during design and code reviews to embed performance best practices early in the SDLC

Establish performance baselines, SLOs and alerting thresholds; track regressions across releases

Champion shift-left performance testing by integrating automated performance gates into CI/CD pipelines, such as Jenkins.

Oracle Database Performance Tuning

Analyze and tune complex SQL queries, PL/SQL procedures and execution plans using Oracle tools (AWR, ASH, ADDM, Explain Plan)

Work with the DBAs in optimize indexing strategies, partitioning schemes and table statistics for high-volume transactional workloads

Identify and resolve contention issues such as locking, latching and I/O bottlenecks in Oracle environments

Partner with DBAs to govern schema changes and monitor long-running query patterns in production

Unix / Linux Systems

Perform OS-level diagnostics using tools such as vmstat, iostat, sar, perf and strace to identify system-level bottlenecks

Hand on experience working in the linux based environments.

Develop and maintain shell scripts for automated performance data collection, log parsing and alert management

AWS Cloud Performance

Lead performance assessment of cloud-native and cloud-hosted workloads on AWS – including EC2, RDS, ECS, EKS and Lambda

Conduct right-sizing exercises and cost-performance trade-off analyses across compute, storage and networking tiers

Leverage AWS-native monitoring and observability tools (CloudWatch, X-Ray, Trusted Advisor) alongside third-party APM platforms

Define auto-scaling policies and capacity planning models to ensure consistent performance under variable load

Technical Leadership

Mentor and guide junior and mid-level engineers in performance testing methodologies and tooling

Present findings, root cause analyses and remediation plans clearly to engineering and product leadership

Maintain documentation of performance benchmarks, runbooks and architectural recommendations

Drive cross-team alignment on performance standards and engineering best practices

Required Qualifications

8+ years of overall software engineering experience with at least 4 years focused on performance engineering and testing

Deep expertise in Java application performance – JVM tuning, profiling tools (JProfiler, VisualVM, YourKit, etc.), memory and thread analysis

Hands-on Oracle performance tuning experience – SQL optimization, AWR/ASH analysis, execution plan interpretation

Strong command of Unix/Linux OS internals and system-level diagnostics

Proven experience designing and executing performance tests using industry-standard frameworks (JMeter, Gatling or equivalent)

Working knowledge of AWS services and cloud performance patterns

Experience integrating performance testing into CI/CD pipelines (Jenkins, GitHub Actions or equivalent)

Excellent written and verbal communication skills with a track record of influencing technical decisions

Preferred Qualifications

Experience with distributed tracing and APM tools (AppDynamics, etc.)

Familiarity with microservices and containerized workloads (Docker, Kubernetes)

Exposure to Chaos Engineering principles and fault-injection testing

AWS certifications (Solutions Architect, DevOps Engineer or equivalent)

Background in healthcare technology or regulated SaaS environments

What We Offer

Opportunity to lead high-impact performance initiatives on mission-critical enterprise platforms

A collaborative, engineering-first culture that values depth of expertise and continuous learning
