Job Overview

Team Context:

The Prime Services horizontal team is a critical component of our engineering organization, focusing on delivering robust and high-performance solutions tailored to the unique demands of Prime Services applications. Within this structure, the Non-functional team acts as a horizontal gating function, ensuring the scalability, robustness, and overall resilience of our applications through rigorous and effective testing methodologies. We are committed to upholding the highest standards of application quality, performance, and stability across Prime, Futures, and Clearing applications.

Your Role as Engineer:

As a Non-Functional Testing Engineer (AVP), you will be a hands-on technical expert focused on the execution and delivery of non-functional testing initiatives for Prime, Futures, and Clearing applications. You will apply your strong technical expertise in performance engineering, observability, and systems profiling to ensure applications meet stringent performance, scalability, reliability, and security requirements. Your primary focus will be on:

• Execution & Delivery: Designing, developing, and executing comprehensive non-functional testing strategies and plans, ensuring high-quality delivery.
• Technical Deep Dive: Applying deep technical knowledge to conduct hands-on testing, detailed analysis, and tuning, directly contributing to the optimization of application performance.
• Tooling & Automation: Developing and maintaining advanced testing frameworks, tools, and simulations that mimic real-world operational scenarios, including performance test scripts and automation.
• Collaboration & Integration: Working closely with development, architecture, DevOps, Production Support, and UAT teams to integrate non-functional testing into CI/CD pipelines and embed requirements early in the development lifecycle.
• Problem Solving: Identifying and analyzing performance bottlenecks, failure points, and risks within application architectures, and providing actionable insights for resolution and optimization.

Where You Fit In:

You will be at the intersection of engineering excellence and critical business operations within the Prime, Futures, and Clearing spaces. Your direct, hands-on contribution will significantly impact on the reliability and performance of our applications, which are fundamental to our clients' success and our market position. You will be instrumental in ensuring that our technology not only functions but excels under pressure, providing a stable and scalable platform for complex financial operations. This role offers the opportunity for significant technical contribution, driving innovation, and making a tangible impact on high-visibility projects within a dynamic and intellectually stimulating environment.

Key Responsibilities:

• Non-Functional Testing (NFT) Execution: Design, develop, and execute comprehensive Non-Functional Testing (NFT) strategies including performance, load, stress, endurance, and resiliency testing for Prime, Futures, and Clearing applications.
• CI/CD Integration & Collaboration: Work closely with application development, DevOps, and Production Support teams to integrate non-functional testing into CI/CD pipelines, ensuring seamless and continuous quality assurance.
• Performance Scripting & Workload Modeling: Develop and maintain robust performance test scripts, scenarios, and realistic workloads based on detailed business and technical requirements.
• Application Profiling & Tuning: Perform in-depth application profiling and tuning, including heap and thread dump analysis, Splunk and other log profiling, SQL profiling, and AWR analysis to precisely identify performance bottlenecks at the code, configuration, and architectural layers.
• Bottleneck Identification & Optimization: Actively identify performance bottlenecks and architectural limitations, analyzing test results to provide actionable insights and recommendations for improving application throughput, latency, scalability, and overall capacity.
• Capacity Planning Support: Support capacity planning initiatives by identifying infrastructure headroom requirements and proactively addressing gaps between production and performance environments.
• Observability & Monitoring Contribution: Contribute to building and improving observability and monitoring capabilities using industry-standard tools and practices.
• Defect Triage & Root Cause Analysis: Participate in performance defect triage and conduct thorough root cause analysis with cross-functional teams to resolve complex performance issues.
• Resiliency & Chaos Engineering: Support resiliency and reliability initiatives, including participation in controlled failure testing and chaos engineering exercises (where applicable), to validate system robustness.
• Process Adherence & Documentation: Ensure strict adherence to Non-Functional Testing standards, processes, and best practices throughout the SDLC. Document test approaches, results, metrics, and recommendations using Confluence or similar knowledge repositories.

Experience:

• 5-7 years of hands-on experience working with Performance Testing and Performance Engineering, with a proven track record in optimizing complex financial applications.
• 2-3 years of practical experience specifically in Chaos Engineering, designing and executing experiments to validate system resilience and fault tolerance.
• Excellent knowledge of performance engineering principles, observability techniques (including tools like Splunk, Grafana), resiliency patterns, and Site Reliability Engineering (SRE) practices.
• Proficient in identifying bottlenecks and recommending optimization strategies to improve applications' throughput and capacity.

Technical Skills:

• Software Development Lifecycle & Methodologies: In-depth knowledge of software development and testing lifecycle methodologies, with extensive experience in Agile practices, project management, and issue tracking using Jira.
• Performance Engineering Tools: Proficient with leading performance testing tools including LoadRunner, LoadRunner Enterprise, and JMeter, along with custom scripting for test automation.
• Observability & Monitoring Platforms: Well-versed in observability and monitoring solutions such as AppDynamics, Splunk, Grafana, and the ELK (Elasticsearch, Logstash, Kibana) stack.
• Cloud Native & Distributed Technologies: Experience with containerization and orchestration technologies like OpenShift and Kubernetes, and distributed messaging systems like Kafka.
• Programming & Database Expertise: Hands-on experience with programming languages (e.g., Python, Java) and database technologies (e.g., Oracle DB, PostgreSQL, SQL).
• Documentation & Collaboration: Working knowledge of Confluence for comprehensive documentation and knowledge management.

Communication & Collaboration:

• Strong analytical and problem-solving skills with the ability to explain complex performance issues clearly and concisely.
• Effective verbal and written communication skills for interacting with technical and business stakeholders.
• Proven ability to collaborate effectively with distributed, cross-functional technology teams.
• Willingness to mentor junior engineers on non-functional testing concepts and tools.

Education Qualification:

• Bachelor's/University degree, or equivalent practical experience, preferably in Computer Science or Information Systems.
