Title: Senior Full Stack Developer (Backend Focus)

Salary Range: $85,000 to $92,000 per year (CAD)

Employment Type: Full Time, Permanent

Location: Windsor, Ontario (in person)

Reports To: Technical Lead

Company

Hearn Industrial Services (HIS) keeps automotive supply chains moving. We run warehousing and distribution operations for major automotive manufacturers, including Ford and Stellantis, across sites in Canada and the United States. Our systems move real parts to real assembly lines every day, so the software you build shows up on the warehouse floor almost immediately.

The Team

You will join a small, collaborative in house development team led by the Technical Lead, within an IT function HIS is actively building and investing in. The team supports our warehouse management, ERP, integration, scanning, and reporting systems, works side by side on site, and uses AI tools in everyday development.

Growth Opportunities

• Shape a growing function. Help set the standards and practices of a team still being built.
• Broaden your expertise. Work across the whole business, including direct OEM integrations.
• Lead on emerging technology. Evaluate and introduce new tools, including AI.
• Grow as a technical leader. Mentor developers and take on more as the team expands.

Why You Will Love This Role

• Transparent, competitive pay. $85,000 to $92,000 per year, posted up front.
• Work that matters. Your code reaches production fast and supports major automotive brands.
• Low red tape. Decisions are made by the people doing the work, with a short path to approval.
• Benefits. A benefits package that begins after a 90 day probationary period.
• Work life balance. Regular weekday hours with no on call or after hours requirements.

Summary Description

Reporting to the Technical Lead, you will design, build, and maintain the backend platforms, APIs, and integrations that keep warehousing operations running for our automotive OEM customers. The emphasis is on backend engineering and software architecture: sound application design, reliable services, well designed databases, and dependable integrations with partner and customer systems.

Responsibilities

• Design, build, and maintain backend services and APIs that power warehouse, inventory, and shipping applications.
• Model, optimize, and maintain relational databases that support high volume transactional workloads.
• Develop and own integrations between internal systems and partner platforms.
• Shape application architecture, including service boundaries, domain models, and integration patterns, and document key design decisions.
• Guide technical direction by reviewing designs, recommending improvements to existing systems, and planning the modernization of legacy applications.
• Implement background jobs, scheduled processes, and queue-based workflows.
• Build internal web interfaces such as dashboards, operator tools, and admin panels on top of backend services.
• Write automated tests, participate in code reviews, and contribute to CI/CD pipelines.
• Support and troubleshoot production systems during regular business hours.
• Explore and introduce emerging technologies, including AI tools, to improve how we work.

Position Characteristics

This role focuses on problems where reliability matters. A delayed integration or a slow query can affect a shipment to an assembly plant, so the work calls for careful analysis and sound design. You will balance long term maintainability with current needs, modernizing existing applications while applying clean, testable architecture to new work.

You will have real influence over design, tooling, and testing decisions, in partnership with the Technical Lead.

• Strong relational database skills, including schema design and query optimization, using SQL Server, Oracle, or PostgreSQL.
• Working knowledge of Blazor (preferred) or another modern frontend framework such as React, Angular, or Vue, sufficient to build internal tools and dashboards.

Assets

• Experience designing and maintaining REST APIs in production (ASP.NET Core Minimal APIs is a plus).
• Exposure to warehousing, logistics, or the automotive industry, ideally supporting Ford, Stellantis, or Tier 1 suppliers.
