• Lead moderately complex initiatives and deliverables within technical domain environments
• Contribute to large scale planning of strategies
• Design, code, test, debug, and document for projects and programs associated with technology domain, including upgrades and deployments
• Review moderately complex technical challenges that require an in-depth evaluation of technologies and procedures
• Resolve moderately complex issues and lead a team to meet existing client needs or potential new clients needs while leveraging solid understanding of the function, policies, procedures, or compliance requirements
• Collaborate and consult with peers, colleagues, and mid-level managers to resolve technical challenges and achieve goals
• Lead projects and act as an escalation point, provide guidance and direction to less experienced staff

Required Qualifications:

• 4+ years of Software Engineering experience, or equivalent demonstrated through one or a combination of the following: work experience, training, military experience, education

Job Expectation:

• Performance Engineering Expertise
• LoadRunner expert: HTTP/HTML, Web Services, Java Vuser.
• Advanced scripting: correlation, parameterization, think-time modeling, error handling, custom logic, and data-driven frameworks.
• Deep understanding of Java performance tuning, GC behavior, JVM internals, thread/heap analysis.
• Deep understanding of.NET performance tuning, CLR internals, thread pool behavior, async/await performance characteristics, memory/GC modes (Server/Workstation), and heap analysis.

• Cloud-Native & Container Platforms
• Hands-on with Kubernetes/OpenShift for performance testing microservices.
• Analyzes pod-level CPU/memory, HPA responsiveness, and autoscaling dynamics.
• Evaluates container limits/requests, node saturation, and cluster-level constraints impacting performance.
