About the Role
We are looking for a hands-on Performance Tester.
This role goes beyond running load tests. We are looking for someone who can be given an unexplained performance issue and independently determine where to investigate—application, Kubernetes/AWS infrastructure, JVM, logs, or PostgreSQL—and drive the problem through to root cause.
You will work on Tecsys Elite, our enterprise supply chain platform supporting warehouse, healthcare, hospital, and pharmacy operations.
What You’ll Do
• Design and execute performance, load, stress, scalability, and endurance tests.
• Build realistic workload models and performance test plans.
• Investigate performance issues across Kubernetes, AWS, Java/JVM, application logs, and PostgreSQL.
• Build and maintain performance tests using JMeter and critical UI validations using Playwright.
• Analyze pod/node metrics, resource limits, autoscaling, JVM behavior, slow queries, execution plans, locks, and indexing.
• Use monitoring and APM tools such as Datadog to identify regressions and validate improvements.
• Create and troubleshoot test environments and large-scale test datasets.
• Work directly with developers to identify issues and verify fixes.
• Use Python for scripting, automation, and analysis.
Requirements
Qualifications:
• 5+ years of hands-on performance or scalability engineering experience.
• Recent experience testing applications in cloud and Kubernetes environments.
• Strong hands-on experience with JMeter.
• Experience with Playwright and APM/monitoring tools such as Datadog.
• Practical knowledge of AWS, Kubernetes, JVM performance, and PostgreSQL troubleshooting.
• Experience reviewing database execution plans and investigating slow queries.
• Comfortable with Linux, Git, Python, and modern IDEs.
• Able to independently configure and troubleshoot test environments and data.
• Must be legally eligible to work in Canada.
• Experience with WMS, supply chain, healthcare, pharmacy, SRE, platform engineering, or backend development is an asset.
Benefits
Why You’ll Love It Here
• Remote-first flexibility and the trust to manage your own time
• Benefits and vacation from day one
• Pension plan with competitive employer contribution
• Employee events and community initiatives
