Job description

PLATO is Canada’s only Indigenous‑led, Indigenous‑staffed software testing services firm. We insist on working with quality people who share our passion for quality testing and have built a team of people who also believe quality is the most important deliverable. Our team of software testing specialists believes that better software leads to a better world.

We are committed to building strong communities – PLATO trains and employs members of First Nations, Metis and Inuit communities across the country and strives to build a network of 1,000 Indigenous software testers across Canada. PLATO has offices on or near Indigenous communities across Canada in Fredericton, Sault Ste Marie, Ottawa/Gatineau, Regina, Prince Albert, Calgary and Vancouver.

We are looking for Senior Test Engineer providing immediate technical relief and capability building for a government software company scaling across multiple provincial implementations. You’ll tackle critical backend testing gaps while upskilling a junior team and partnering with an external automation vendor to establish sustainable testing practices.

What you’ll do

Responsibilities

• Design and implement API contract testing for a Ruby on Rails application with a PostgreSQL backend
• Build mock services and test harnesses for system integrations
• Provide hands‑on testing support for critical client deployment milestones
• Work alongside intermediate and junior QA team members to relieve backlog pressure
• Establish integration testing infrastructure the current team can maintain
• Transfer knowledge and upskill junior testers in API testing practices
• Partner with an external automation vendor to ensure the technical foundation supports their work
• Document testing approaches for repeatability across other products

What Success Looks Like

• Deployment milestones hit on schedule with confidence
• Current QA team reports meaningful workload relief and demonstrates new API testing capabilities
• Mock services deployed for critical integrations enabling independent testing
• Automation partner integration happens smoothly with clear technical handoffs
• Test infrastructure is documented and maintainable beyond your engagement

What you’ll need

Qualifications

• 7 years software testing with deep API/integration expertise
• Strong hands‑on experience: REST API contract testing, service virtualization/mocking, integration test frameworks
• Technical proficiency: Ruby on Rails, PostgreSQL, Azure cloud infrastructure
• Experience designing and implementing test infrastructure, not just writing tests
• Government software or regulated industry testing experience
• Comfortable mentoring junior testers while delivering hands‑on work
• Track record working effectively alongside external automation consultants
• Can translate technical testing concepts for non‑technical stakeholders

Working Structure

You’ll work as part of a two‑person consulting team alongside a Quality Transformation Lead who handles organizational process improvement and leadership communication. Your focus is technical execution and capability building. This structure allows you to do deep technical work without the organizational strategy and change management responsibilities.

Ideal Candidate

You’re a senior technical specialist who gets energy from solving hard technical problems and seeing others grow. You’re comfortable being the technical expert on a team while someone else handles strategic conversations with leadership. You’ve worked on high‑stakes projects where integration failures have real consequences and you know how to build testing infrastructure that outlasts your engagement.
