We’re looking for a Senior Software Engineer who takes end-to-end ownership, thrives in ambiguity, and wants to build systems that matter. This role is central to modernizing our platform so we can better detect fraud, assess risk, and move faster as a business. You’ll help shape architecture, influence technical direction, and own what you build—from design to production. The software you’ll build directly influences financial trust, fraud prevention, and risk decisions across Canada’s automotive ecosystem. Your work will have real impact at scale—and you’ll have the autonomy and responsibility to shape how it’s done.

If you’re motivated by ownership, technical challenges, and building systems that truly matter, you’ll feel at home here.

What You’ll Do:

Build & Evolve Critical Systems

- Improve and extend a large, production-grade codebase with a strong bias for clean code, testing, and long-term maintainability.

- Design and implement scalable, resilient solutions using modern architecture principles (modularity, clear boundaries, observability).

- Modernize legacy components to unlock new capabilities in fraud detection and risk analysis.

Own Architecture & Technical Decisions

- Drive architectural discussions and decisions, balancing pragmatism with technical excellence.

- Set and enforce high quality bars for new services and modules, with a focus on testability, performance, and reliability.

- Identify and reduce technical debt in ways that measurably improve developer velocity and system robustness.

Build With an Ownership Mindset

- Work across the full software lifecycle: design, build, deploy, operate, and iterate.

- Embrace a “you build it, you run it” DevOps mindset alongside your team.

- Make thoughtful trade-offs between effort, quality, and user value—always with accountability for outcomes.

Collaborate & Lead

- Work closely with product managers, designers, and other engineers in an agile, cross-functional team.

- Contribute ideas, challenge assumptions, and continuously improve how we build software.

- Mentor and support other engineers through code reviews, design discussions, and technical leadership.
