Systems/Application Developer

Mississauga, Ontario

$65,000 - $100,000 + ERP Training + Hybrid Work + Career Growth + Excellent Benefits

Excellent opportunity for a Developer to take on a key internal role with a growing electronics manufacturer. This is a high-impact position focused on ERP customization, internal tool development, and digital transformation initiatives.

On offer is a technically varied role where you'll develop custom applications, collaborate closely with internal departments, and contribute to modernizing critical systems within a fast-paced manufacturing environment.

You'll join a tight-knit IT team as their third hire, supporting a business that designs and manufactures control systems used in challenging environments including oil & gas, marine, mining, power generation, and industrial automation. With new investment into digital systems, there's a clear path for long-term growth and specialization.

In this position, you'll be responsible for developing and supporting internal web-hosted tools, integrating them with ERP systems, and working directly with stakeholders to streamline workflows. You'll gain hands-on experience across the full stack, and benefit from ERP training as the business transitions from legacy systems.

This role would suit a detail-oriented and proactive developer with 2+ years of experience (or a strong intern-level candidate) who is eager to grow into a business systems specialist or internal ERP consultant.

The Role:

  • Full stack development of internal business applications
  • Customizing ERP-integrated tools hosted on-prem
  • Collaborating with operations, finance, and production to optimize digital workflows
  • Supporting the migration from legacy systems with testing and implementation
  • $65,000 - $100,000 + ERP Training + Career Progression + Excellent Benefits


The Person:

  • Experience building custom applications (intern to mid-level considered)
  • Proficient in Java, Python, or C#
  • Solid understanding of front-end and back-end development
  • Analytical, detail-oriented, and proactive in identifying system improvements
  • Keen to learn ERP systems and support digital transformation in a manufacturing environment
  • Comfortable working independently and engaging with cross-functional teams
