Technical Lead

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. 

• 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. 

• 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 

• 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 

• 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 

• 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 

• 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 

• 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
