Our product includes intuitive smartphone apps for drivers, a powerful modern web application and dashboard for logistics teams, and automatic notifications and real-time tracking for recipients. Onfleet powers millions of deliveries every week for thousands of businesses around the world across a range of industries, from grocery and prepared meals to pharmacy, flowers, and furniture.\nAbout the role\nOnfleet 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.\nThe 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.\nEveryone 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.\nIf 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.\nHow we work\nOur 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.\nWe 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.\nWe 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.\nWhat you'll do\nBuild 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.\nDrive 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.\nApply your agentic workflow in both greenfield and legacy code, meeting the different challenges each presents.\nDesign and implement high-quality, scalable software in parallel with the tests that validate it.\nDrive and show ownership of features end to end: research/planning, design, implementation, validation, deployment and monitoring in production.\nContinuously refactor and simplify code to improve clarity, maintainability, and long-term system health, including making hard-to-reach code testable.\nDevelop and refine our APIs, webhooks, and other integration surfaces.\nWork in a healthy Agile/Scrum cadence: reliable estimates, proactive and clear communication, and follow-through on commitments.\nTroubleshoot and resolve complex technical issues, including participation in the on-call rotation.\nCollaborate 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.\nWhat you'll bring (required)\nA scrutinizing, questioning mindset: you don't accept output, your own or an agent's, at face value, and you surface problems early. You’re open and honest when you see a problem, and seek opportunities to help all of us improve.\nBachelor's degree in Computer Science or a related field, or equivalent professional experience, and strong CS fundamentals: data structures, database fundamentals, API design, testing, and an instinct for clean, maintainable code.\nFront-end and back-end experience, having shipped multiple features that cross the full application stack from ideation to production use by real customers.\nAutomated testing experience across unit, integration, and end-to-end layers, including hands-on experience with a browser or end-to-end framework such as Playwright or Selenium. \n4 or more years of hands-on professional software engineering experience building, shipping, and operating production-quality, reliable systems.\nAt least 3 years of professional experience in our core stack: Node.js and React, in TypeScript or JavaScript. \nExperience with creating software using disciplined agentic flows, from prompt-instructing to complete development orchestrations.\nExcellent written and spoken English. You can work entirely in English on a distributed team, explain complex technical ideas clearly, and write docs and code reviews your teammates rely on. This is roughly equivalent to a C1 level of English.\nNice to have\nEspecially valuable for this seat. We don't require these, but candidates who bring them will stand out from the crowd.\nPrior experience building comprehensive automated test suites, going beyond testing your own tickets to building coverage a team relied on. Bonus points for having worked as a Software Developer in Test (SDET).\nHands-on CI ownership: you have created, configured, fine-tuned, or troubleshot a CI pipeline (GitHub Actions or equivalent), not just consumed one that someone else built.\nTest-Driven Development (TDD) experience.\nExperience with test data and environment management: getting a realistic system into a known state quickly and repeatably.\nExperience with a statically typed, compiled language other than TypeScript, for example Rust, Go, Java, C#, or C++.\nDeeper front-end specialization in React, for example design systems, accessibility, or performance work.\nFamiliarity with cloud service design patterns and modern software architecture.\nFamiliarity with AWS and cloud-native services; microservices and containerization.\nProficiency with NoSQL and other modern data-storage technologies.\nExperience working remotely as part of an international team whose common working language is English, collaborating day-to-day with teammates in other countries.\nLocation and Benefits\nThis is a remote role, open only to candidates based in Latin America or Canada.\nOnfleet offers flexible work arrangements; you can work from home or anywhere with a reliable internet connection.\nThe team works on US Pacific Time. You'll need to reliably work a schedule that frequently matches US Pacific business hours (9am-5pm PT).\nFlexible PTO\nLaptop and work-from-home setup stipend\nMonthly technology stipends (internet and AI tooling)\nOnfleet is an Equal Opportunity Employer\nOnfleet's culture is one that strongly values diversity in its workplace and we are committed to working with potential team members who can bring diverse perspectives and experience to our company and culture.\nWe do not make hiring or employment decisions on the basis of race, color, religion, creed, gender, national origin, age, disability, veteran status, marital status, pregnancy, sex, gender expression or identity, sexual orientation, citizenship, or any other basis protected by applicable local, state or federal law.\nWe highly encourage members of underrepresented groups to apply and we will consider qualified applicants with arrest and conviction records.\nCompensation\nThe base salary range for this role is $60K USD to $80K USD per year, depending on experience, skills, and background. Where an offer lands within that range reflects the engineering level and the depth of experience a candidate brings to the role.\nHow we hire\nYou need an identity-verified LinkedIn profile to apply. That's the free \"Verified\" badge, the shield icon next to your name. We check for it, and applications without it don't move forward.\nBefore any offer, we verify your identity and work history. That includes a live video ID check and reference calls. We use AI, automated systems, and a person to review applications: every application that meets the requirements is also read by an engineering leader or a recruiter. If you misrepresent your identity or experience, the process ends.","description_format":"text","description_chars":9632,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Flexible schedule"],"hiring_locations":[{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Delivery","Supply Chain & Logistics Software"],"lifecycle":[{"event":"open","at":"2026-11-10T02:16:13Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":3,"expected_fill_days":30,"reasons":["conf:0","win:early"],"computed_at":"2026-11-10T03:09:11Z"},"pay":null,"html_url":"https://alion.io/job/onfleet-full-stack-engineer","json_url":"https://alion.io/job/onfleet-full-stack-engineer.json","meta":{"generated_at":"2026-11-10T03:09:11Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":7318,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":171880},"rest":"https://alion.io/mcp/rest/get_company?id=171880"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fonfleet-full-stack-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fonfleet-full-stack-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fonfleet-full-stack-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/onfleet-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fonfleet-full-stack-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3998254}},{"tool":"search_jobs","arguments":{"company":"onfleet.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3998254},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
