Job description

// About Providius

Providius has been at the forefront of innovation in the Media & Entertainment industry for over a decade, delivering solutions to complex challenges in IP media and IT infrastructure within mission-critical environments.

Headquartered in Hamilton, Ontario, Canada, we are a privately held company focused on building practical, reliable systems that solve real-world problems.

// Position Overview

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.

// Duties and 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
  • Set quality standards and mentor others on testing practices as the team grows

Requirements

// Tech Stack
  • Languages: Python, Java, TypeScript
  • Test frameworks: pytest, JUnit, Playwright or Cypress
  • API and load testing: Postman, k6 or JMeter
  • CI/CD: automated pipelines, test gates, coverage reporting
  • Data: PostgreSQL, TimescaleDB
  • Infrastructure: Linux (Ubuntu), Docker
  • Tools: JIRA, Bitbucket
// Required Skills / Experience
  • 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
// Nice to haves
  • 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)
// Why join Providius
  • Own quality across systems that operate in real-time, high-stakes environments
  • Small team with high ownership and direct impact
  • Opportunity to shape testing practices and grow technical leadership
