role: performance test scripting

location: mexico-remote

duration: long term contract

job description:

8+ years over all experience with 5+ years of experience in performance testing

1. Performance test scripting

- strong experience with jmeter scripting.

- ability to write/debug custom scripts using groovy and/or javascript.

- experience with correlation, parameterization, assertions, timers, controllers, reusable functions, and custom logic.

- ability to troubleshoot script failures, dynamic values, authentication, cookies, headers, and session handling.

2. Workload modeling and test design

- ability to analyze business flows and design realistic workload models.

- experience designing load, stress, endurance, spike, and scalability tests.

- ability to calculate user load, tps/tpm, pacing, think time, ramp-up, and transaction mix based on production usage.

- experience validating test data readiness and environment readiness.

3. Production log and traffic analysis

- ability to analyze production logs and traffic patterns to identify peak usage, transaction volume,

error trends, and response-time behavior.

- experience using production metrics to create accurate performance test scenarios.

- ability to compare production behavior with test environment results.

4. Monitoring and observability

- hands-on experience with datadog, appdynamics, and kibana.

- ability to monitor application, api, jvm/.net, iis, database, container, and infrastructure metrics.

- experience identifying bottlenecks related to cpu, memory, gc, thread pools, connection pools,

database queries, downstream services, cache, and network latency.

- ability to correlate jmeter results with monitoring tool metrics.

5. Aws / cloud / container monitoring





- experience monitoring applications hosted on aws cloud platforms.

- understanding of containers, kubernetes/ecs/eks, pods, services, nodes, cpu/memory limits,

autoscaling, and cloud infrastructure behavior.

- ability to analyze container-level performance issues and work with devops teams.

6. Distributed testing setup

- experience setting up and executing distributed performance tests.

- good understanding of load generators, controller-agent setup, firewall/port issues, data file distribution,

result collection, and capacity planning.

- ability to debug common distributed testing challenges such as connectivity issues, file path issues,

permission issues, resource saturation, and inconsistent results.

7. Performance analysis and reporting

- ability to analyze response times, throughput, error percentage, percentiles, saturation points, and bottlenecks.

- strong skills in preparing clear observations and recommendations.

- ability to explain performance findings to technical and non-technical stakeholders.

- experience working with development, infrastructure, database, devops, and application teams for root cause analysis.

8. Leadership and communication

- should be able to lead performance testing activities independently.

- should have strong communication skills and the ability to coordinate with multiple teams.

- should be proactive in identifying risks, blockers, environment issues, and test data gaps.

- should be able to mentor junior performance testers if needed.
