Engineering Full-Stack Developer in Toronto

MaintainX is a leading mobile-first work execution platform for industrial and frontline teams. More than 13,000 customers, including Duracell, McDonald's, Shell, DHL and Volvo, use MaintainX to cut unplanned downtime and run better operations, across 13.9 million managed assets and 79.5 million completed work orders.

About the Team: Core is the heart of the MaintainX CMMS: the work orders, planning and scheduling, inventory and parts, reporting, and asset hierarchy that frontline teams touch every day. It is also where some of our newest investment is happening, including two newly formed teams building a Work Execution Platform and a rebuilt Technician Experience from scratch.

Teams You Might Join:

• Planners: Planner and scheduler workflows, plus Operating Hours.
• Inventory Management / Parts: Spare parts, purchase orders, forecasting and vendors.
• Home / Reporting: The Overview screen, plus shared and scheduled reports.
• Work Execution Platform: The work order primitives the product runs on: recurrence, assignment, calendar, procedures, automations and permits.
• Technician Experience: GPS check-in, field UX and offline state for technicians in the field.
• Enterprise Data Management: Global, multi-site platform capabilities, templates, asset hierarchy and location, and dynamic asset forms.

What You'll Work On: Build and improve the workflows customers use every day, from scheduling and parts management to reporting. Solve hard product problems: dense, data-heavy interfaces, large datasets, offline behaviour and multi-site scale. On our newly formed teams, shape architecture and engineering practices from the ground up. Make complex workflows feel simple on desktop and mobile.

The Role: Ship features end to end, from planning through production. Partner directly with Product Managers and Designers to shape your team's roadmap, not just execute against it. Own a feature area or system's long-term health: reliability, performance, and the parts of the codebase nobody notices until they break. Review code and mentor other developers on your team. Raise the bar on tooling, testing, and delivery practices. Our core stack is TypeScript, React, Node.js, and MySQL. Some teams use C# or Python. You don't need to already know every piece of it to apply. You'll land on a team of 5 to 10 people and take on-call rotation as part of the role. Within your first 6 months, you'll own a feature area or system outright.

Where We Work: We don't have a minimum in-office mandate, but we prefer our teams to be located around our office hubs. In Canada this includes: Montreal and Toronto.

Qualifications:

• 5+ years of professional experience building full-stack web or mobile products.
• Deep hands-on experience with TypeScript, React, and Node.js.
• Experience with mobile-first, responsive, iterative development.
• A track record of writing maintainable, testable code you're comfortable handing off to someone else.
• Strong written and verbal communication: you can explain a technical tradeoff to a designer or a support lead as easily as to another developer.
• Comfort making progress on a problem before the spec is fully settled, adjusting as you learn more.
• Day-to-day use of AI tools in your development workflow, not just occasional experimentation.

Nice to have:

• GraphQL, React Native, or SQL database experience.
• Experience with scheduling or calendar UIs, data-heavy front ends, offline-first or sync architectures, multi-tenant or enterprise platforms, workflow engines, or inventory and transactional systems.

Our mission is to keep the physical world running. Factories, fleets, hospitals and campuses stay up because the people who maintain them have tools worth using. That is what we build.

Compensation and benefits: Base pay is one part of the package. Depending on the role, compensation may also include commission, an annual bonus and equity. Benefits differ by country.

Belonging: We take pride in a culture where everyone can thrive.

Competitive pay, meaningful equity, performance bonuses, and rewards for outsized impact. Flexibility that fuels speed: Hybrid work, unlimited time off, and the autonomy to move fast and own your results. Growth at startup velocity: L&D budget, real ownership, stretch opportunities, and recognition for bold thinking and innovation. Health & wellness that keeps you at your best: Comprehensive benefits, wellness programs, parental support, and access to the tools you need to perform. A culture built for builders: Catered lunches, off-sites, hackathons, energetic teams, and a community that celebrates big wins and resilience.
