Full-Stack Engineer

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Full-Stack Engineer based in Canada . Join a globally distributed engineering team building advanced software solutions that power delivery logistics and real-time orchestration for businesses worldwide. In this role, you will contribute across the full technology stack, developing new features, improving existing architecture, and strengthening APIs and integrations. You will work primarily with Node. js and React, using JavaScript or TypeScript, while also engaging with newer technologies such as Rust. The environment combines greenfield development with the continuous improvement of established systems, placing strong emphasis on software quality, automated testing, and maintainability. AI-assisted development is central to the engineering workflow, offering an opportunity to shape advanced agentic practices and tools. You will have end-to-end ownership of features while collaborating with cross-functional teams in a quality-driven, international environment. Accountabilities - Build, refine, and maintain agentic development workflows, contributing to the team's use of AI throughout the software lifecycle, from requirements and technical specifications to implementation and testing. - Design, develop, test, and deliver scalable, high-quality full-stack software across new and existing systems. - Drive software quality through thorough verification, automated testing, and both AI-assisted and human code reviews. - Review AI-generated code and architectural recommendations critically, ensuring solutions meet engineering standards before they are merged or deployed. - Take ownership of features from research and planning through design, implementation, validation, deployment, and production monitoring. - Improve legacy systems through refactoring, simplification, better test coverage, and clearer boundaries between components. - Develop and enhance APIs, webhooks, and integration capabilities across the platform.

- Build and maintain automated unit, integration, and end-to-end tests as part of the development process. - Contribute actively to Agile/Scrum practices through reliable estimates, clear communication, and consistent delivery. - Troubleshoot complex technical issues, support production reliability, and participate in on-call rotations. - Collaborate with product managers and cross-functional partners to prioritize features and fixes. - Support team development through pairing, constructive code reviews, knowledge sharing, and technical documentation. Requirements: - At least 4 years of professional software engineering experience building, deploying, and operating reliable production systems. - At least 3 years of hands-on professional experience with Node. js and React, using JavaScript or TypeScript. - Experience delivering full-stack features across both frontend and backend, from initial concept through production use. - Strong computer science fundamentals, including data structures, database concepts, API design, software testing, and clean coding practices. - Bachelor's degree in computer science or a related field, or equivalent professional experience. - Practical experience with automated testing at unit, integration, and end-to-end levels, including browser testing frameworks such as Playwright or Selenium. - Experience using structured AI-assisted or agentic software development workflows, from prompt-based instructions to more comprehensive development orchestration. - A critical, questioning mindset, with the ability to evaluate code and architectural proposals rather than accepting generated or independently written output at face value. - Strong communication skills and the ability to explain complex technical concepts, contribute to code reviews, and produce clear documentation.
