About the role

First Quality Engineer on the Risk Platform team responsible for defining quality standards, building automation, tooling, and release verification for risk-critical systems across onboarding, transaction scoring, screening, and other risk decisioning flows.

Responsibilities

  • Own the automation and regression coverage that helps risk decisioning flows remain reliable across onboarding, transaction scoring, screening, and related systems.
  • Build stable test data and isolated environments that make automated testing deterministic and trustworthy.
  • Establish contract testing and integration coverage that catches service breakages before they reach release.
  • Improve confidence in jurisdiction-specific behaviour by validating regional rules, thresholds, and regulatory requirements.
  • Define release-quality gates and post-release verification that confirm risk systems behave correctly in production.
  • Partner with Engineering and Product to set acceptance criteria, support major client-facing projects, and raise the quality bar across the team.

Qualifications

  • Experience as an SDET or Software Engineer in Test, with strong programming skills and a track record of building test frameworks rather than only writing test cases.
  • Experience testing large-scale distributed backend systems, including REST APIs, message-driven flows, and service-to-service integrations.
  • Hands-on experience with API and end-to-end automation and CI/CD.
  • A strong understanding of reliable testing practices, including deterministic test data, isolated environments, and fast feedback.
  • Experience using AI to accelerate testing, such as LLM-assisted test generation, coverage analysis, or failure triage, and an interest in testing ML models and LLM agents through evaluation, regression testing, and guardrails.
  • Comfort working in a self-directed Agile team, with excellent written and verbal communication.
