Performance Test Engineer

Capco; Bengaluru; Hybrid; INR 2,500,000 - 4,000,000; Full time

Job summary

Capco invites an experienced Performance Test Engineer to join our Bengaluru delivery team. You will own performance testing strategies for distributed systems, shaping baselines, load tests and end-to-end performance criteria to ensure quality releases.

Requirements include hands-on LoadRunner/JMeter expertise, strong observability skills, and proficiency in Java or similar languages. You will collaborate with cross-functional teams, integrate tests into CI/CD, and mentor juniors while driving

Qualifications

• Strong hands-on experience delivering performance testing for distributed systems.

Responsibilities

• Define the performance test strategy aligned to NFRs, SLAs/SLOs, and production usage patterns.
• Establish performance baselines and capacity thresholds; create a repeatable approach for load, stress, endurance/soak, spike, and scalability testing.
• Shape performance acceptance criteria early in the SDLC (shift-left), influencing architecture and design decisions; test design, scripting & execution.
• Analyse requirements, production telemetry, and user journeys to model realistic workloads (mix models, concurrency, pacing, think time).
• Build and maintain performance test scripts and frameworks using tools such as LoadRunner / Performance Center and JMeter
• Configure and run tests across environments, coordinating dependencies (test data, stubs/mocks, third parties, schedules). Monitoring, analysis & optimisation.
• Instrument and monitor application and infrastructure during tests (APM/logs/metrics) to capture response times, throughput, errors, CPU/memory/GC, DB performance, network, and queue behaviour.
• Perform root-cause analysis and produce actionable recommendations (SQL tuning, caching, thread pools, connection pools, API/HTTP tuning, JVM/.NET settings, cloud scaling).
• Validate fixes with re-tests and provide performance sign-off for releases. Automation & CI/CD
• Integrate performance tests into CI/CD pipelines for smoke/baseline performance checks and trend analysis.
• Implement performance regression detection and reporting dashboards; maintain reusable libraries and standards.
• Communicate results clearly to technical and non-technical stakeholders, including risks and release readiness.
• Mentor junior engineers and promote best practices (coding standards for scripts, review processes, environment readiness checklists).
• Contribute to performance governance: NFR reviews, capacity planning input, and incident post-mortems (where performance-related).

Required Skills and experience

• Strong hands-on experience delivering performance testing for distributed systems (microservices/API-driven, event-based, or legacy n-tier).
• Proven expertise in at least one performance tool: Loadrunner / performance center and JMeter
• Solid understanding of performance metrics and analysis: latency percentiles (p95/p99), throughput, saturation points, error budgets.
• Strong technical foundation in:
• HTTP/REST, messaging/queues, caching, load balancing
• Database performance (SQL profiling, indexing concepts, connection pooling)
• OS/process basics, networking fundamentals, and capacity/scaling concepts
• Experience with monitoring/observability tools such as Dynatrace, AppDynamics, New Relic, Splunk, ELK, Prometheus/Grafana (any mix).
• Scripting/programming proficiency (one or more): React, Java, JavaScript, Python

Good to have

• Performance engineering in cloud-native environments (autoscaling, managed databases, service meshes).
• Chaos/resilience testing awareness (timeouts, retries, circuit breakers) and non-functional testing beyond performance (stability, reliability).
• Experience with SRE practices, SLOs, and production performance tuning.
