As the Canadian arm of Europe’s largest online car marketplace, Trader Corporation plays a vital role in transforming how people buy, sell, and finance vehicles. With well-known brands like AutoTrader.ca, AutoSync, and Dealertrack Canada, Trader Corporation is driving digital innovation in the automotive industry — now reaching over 25 million Canadians every month.   This role will be within the Dealertrack Canada team, the country’s leading automotive financing portal, processing over 6.5 million credit applications annually.   ---  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.  What We’re Looking For: * A senior engineer who takes responsibility for results, not just implementations. * Someone who enjoys complex problem-solving and isn’t afraid 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 can think it, you can build it. If you build it, you own it. * Experience leveraging AI, Generative AI (GenAI) to enhance engineering productivity, automate repetitive tasks, and optimize workflows. You should demonstrate the ability to integrate AI-driven solutions into your daily work — such as code generation, debugging, reviews, documentation, and decision support—to improve efficiency for yourself and your teams. A proactive approach to exploring and implementing AI tools that drive innovation and streamline development processes is highly valued.  What's In It For You? We understand that there is life at work and life outside of work. Here are a few benefits we all benefit from that support us to be our creative best.   Benefits from Day 1  * Gym discounts * Employee and Family Assistance program * Virtual wellness events * Conferences & training budget * Regular internal training programs  Financial planning  * Let us help you invest in your future with 3% matching towards your pension and multiple forms of income protection.   Competitive salary  * Annual bonus structure * 3% CPP matching  --- The base salary range for this position is CAD 140,000 – CAD 190,000.
