About the role

Onfleet is hiring a Full-Stack Engineer based in Latin America or Canada to join one of our cross-functional teams as we build out our Orchestration capabilities. You'll be a core contributor across new feature development, architectural improvements, and system integrations. Your work will span our core platforms, APIs, webhooks, and other integration surfaces, evolving courier and orchestration functionality, and improving internal tooling and developer experience.

The majority of backend work is in Node.js, with a growing Rust codebase in our newer projects. Front-end work is in React, with a mix of JavaScript and TypeScript. You'll work across a blend of greenfield development and continual, thoughtful development and refinement of existing systems: creating high-quality, well-tested code, contributing to a healthy Scrum cadence, and helping tame legacy complexity by putting code under test, isolating change boundaries, and simplifying tangled implementations.

Everyone on the team owns quality. Automated tests are part of our Definition of Done, and nothing goes to production without being well reviewed by humans and AI agents. If you bring deeper testing or automation experience, that is a real advantage in this seat and we will put it to work, but it is not a prerequisite.

If you have strong Computer Science fundamentals, care deeply about quality and craft, and bring a scrutinizing, questioning mindset, we'd love to hear from you.

How we work

Our engineers combine Computer Science fundamentals with a principled approach to software development that sets a high bar for quality. We're pragmatic, quality-driven, and deliberate about the tools and practices we adopt.

We code using agents, and nearly 100% of our code is written this way. Success here takes a scrutinizing, questioning mindset: the engineers who thrive are the ones who avoid slop, catch the wrong call before it ships, and drive quality and the right engineering choices forward. Generating code is the easy part; knowing what good looks like, and holding the bar, is the job. To be successful in this role you will need enough expertise in the languages we use to challenge both the code an agent writes and the architecture it proposes.

We also expect every engineer to be an active contributor to how we work, not just a consumer of existing workflows. Improving our agentic workflows, orchestration, and tooling is a core part of the role; we're always looking for ways to raise the team's quality and efficiency, and that's expected from everyone. Desire and excitement for the application of AI to software development are critical to this role. We are seeking candidates who want to work in and maintain leading-edge agentic workflows, and stay there as the models and tools evolve.

What you'll do

• Build and continually improve your own agentic development workflow, and help raise the team's. This goes far beyond prompting for code: we use AI across the whole path, from PRDs to technical specs, epics, and tickets, into development plans, and finally into high-quality code with thorough unit and integration tests.
• Drive quality through disciplined verification and both agentic and human code review, on your own code and your teammates'. Extend our agentic review tooling as you go, and hold the bar on what gets merged.
• Apply your agentic workflow in both greenfield and legacy code, meeting the different challenges each presents.
• Design and implement high-quality, scalable software in parallel with the tests that validate it.
• Drive and show ownership of features end to end: research/planning, design, implementation, validation, deployment and monitoring in production.
• Continuously refactor and simplify code to improve clarity, maintainability, and long-term system health, including making hard-to-reach code testable.
• Develop and refine our APIs, webhooks, and other integration surfaces.
• Work in a healthy Agile/Scrum cadence: reliable estimates, proactive and clear communication, and follow-through on commitments.
• Troubleshoot and resolve complex technical issues, including participation in the on-call rotation.
• Collaborate with product and cross-functional partners to prioritize features and bug fixes, and lift the people around you through pairing, thorough reviews, and writing things down.
