QA Lead

Providius•Hamilton, ON

About The Position

We’re looking for a QA lead to own quality across our engineering work, from defining test strategy to building the tooling and processes that keep our systems reliable. You’ll work across the stack and partner closely with engineering to catch issues early and raise the bar on quality. This role is ideal for someone who is comfortable operating with autonomy, can work through ambiguity, and takes ownership of quality end to end. You’ll set the direction for testing and validation as the team grows.

5+ years in software quality, test engineering, or a closely related role, including lead or senior responsibility
Hands-on experience designing automated test suites across unit, integration, end-to-end, and regression testing
Experience with performance, load, and stress testing of data-intensive or real-time systems
Experience with API and contract testing across distributed services
Ability to take ambiguous requirements and turn them into clear test plans
Strong programming ability for test automation and tooling
Strong debugging and problem-solving skills
Effective communication and collaboration in a team environment

Experience validating data pipelines or machine learning systems
Familiarity with simulation, synthetic data, or scenario-based testing
Experience with chaos, fault-injection, or resilience testing
Experience with security testing and test data management
Familiarity with networking concepts (a strong plus in our domain)

Responsibilities

Define and own the overall test and quality strategy across engineering
Build and maintain automated test suites across unit, integration, end-to-end, and regression testing
Establish performance, load, stress, and soak testing for high-throughput, real-time systems
Lead API and contract testing across services and integration boundaries
Develop test tooling, fixtures, mocks, and simulation environments, including synthetic and scenario-based data
Stand up data validation and ML model validation approaches where ground truth is limited
Build and maintain CI/CD test gates, smoke tests, and release-readiness checks
Drive non-functional testing including security, resilience, and chaos or fault-injection testing
Debug and investigate issues across the system, including production environments when needed
