Auto Repossession & Remarketing

We’relooking 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 rethinking and rebuilding our auto repossession and remarketing platform , a system that directly influences how vehicles are recovered, processed, and remarketed across Canada’s automotive ecosystem. This is an AI-first engineering role —not in name, but in practice.You’llcontinuously evaluate where AI (including LLMs and agentic tools) can meaningfully improve engineering velocity, system quality, and operational efficiency , while applying strong judgment about where it should not be used.

You’llhelp shape architecture, influence technical direction, and own what you build—from design to production. The impact is real, the scale is national, and the responsibility is genuine.

What You’ll Do:

Build & Evolve Critical Systems

• Rethink and reshape core workflows based on a deep understanding of auto repossession and remarketing processes .
• Design and implement scalable, resilient systems using modern architectural principles: clear service boundaries, modularity, and observability.
• Incorporate LLMs and AI-driven components to improve data validation, document processing, and operational decision-making.
• Use AI-assisted and agentic coding tools to accelerate development—whilemaintaininghigh standardsfor correctness, security, and maintainability.

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.
• 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.

What We’re Looking For:

• A senior engineer who owns results , not just implementations.
• Someone who enjoys complex problem-solving andisn’tafraid of legacy systems—or changing them.
• Strong engineering fundamentals: clean code, testing discipline, system design, and performance awareness.
• Strong experience with TypeScript and modern React / Next.js
• Strong experience building production systems with .NET (Core / modern .NET preferred).
• Comfort operating in production environments and learning from real-world feedback.
• A builder’s mindset: If you canthinkit, you can build it. If you build it, you own it.
• Experience leveraging AI, Generative AI (GenAI) toenhanceengineeringproductivity,automaterepetitivetasks, andoptimizeworkflows.YoushoulddemonstratetheabilitytointegrateAI-drivensolutionsintoyourdailywork— suchascodegeneration,debugging,reviews,documentation, anddecisionsupport—toimproveefficiencyforyourselfandyourteams.
