General Manager (Windsor)

About ATMIS Canada

ATMIS is an Indigenous-owned advanced manufacturer and engineering solutions company working in highly regulated, high-performance industries including nuclear, defence, medical, and space systems. Our work supports mission-critical equipment where precision, safety, quality, and innovation are essential.

Position Overview

We are seeking a General Manager to lead and run our Canadian operations, with a focus on aligning sales, engineering, and production into a disciplined, high-performing operating system.

This role is responsible for controlling work intake, enforcing execution discipline, and ensuring the business operates in a structured, predictable, and profitable manner. The successful candidate will act as the central decision-maker across day-to-day operations, ensuring the right work is taken on and delivered effectively.

This is a hands-on leadership role for a builder-operator who can impose structure, drive accountability, and lead execution in a complex, project-based manufacturing environment.

Key Responsibilities

• Own day-to-day business performance, including delivery, throughput, and profitability
• Control and align work intake with production capacity to ensure achievable commitments
• Drive execution of complex, high-reliability projects from quote through delivery with strong governance and accountability
• Oversee and enforce project management frameworks, including scope, schedule, cost, risk, and quality management
• Ensure all work is delivered on time and within budget, with clear ownership of schedule adherence and cost performance
• Establish and monitor financial controls, including budgeting, forecasting, cost tracking, and variance analysis in coordination with the CFO
• Implement and maintain performance metrics and reporting systems to track delivery, financial performance, resource utilization, and quality outcomes
• Ensure robust quality management systems are maintained and continuously improved in alignment with industry standards (e.g., ISO, nuclear QA programs, aerospace quality standards)
• Oversee shop floor operations, including workforce planning, labour utilization, and productivity optimization
• Ensure equipment, tooling, and infrastructure support safe, efficient, and high-quality production
• Enforce alignment between sales, engineering, and production teams, resolving conflicts and setting priorities
• Establish and lead a structured operating rhythm, including regular production and project reviews focused on decisions and performance
• Drive accountability across all functional leaders (sales, engineering, production) for delivery and results
• Identify and eliminate bottlenecks to improve flow of work across the business
• Develop and implement operational strategies aligned with sustainable growth and execution capability
• Build and maintain relationships with key clients, partners, and stakeholders

Qualifications

• Bachelor’s degree in Engineering (Mechanical, Electrical, Nuclear, Aerospace, or related), or a degree in related field; MBA considered an asset
• 10+ years of leadership experience in manufacturing, operations, or project-based environments
• Demonstrated success managing complex, custom, or project-driven operations
• Strong background in program or project management methodologies
• Proven experience with financial management, including budgeting, forecasting, and cost control
• Experience overseeing shop floor operations or technical production environments
• Working knowledge of quality management systems and standards (e.g., ISO 9001, CSA N299, AS9100 or equivalent)
• Experience in custom manufacturing, automation, defence, nuclear, or similar industries preferred
• Proven track record of delivering work on time, within scope, and on budget
• Professional Engineer (P.Eng.) designation or PMP certification considered an asset

Key Competencies

• Strong operational leadership and decision-making capability
• Program and project execution discipline
• Financial oversight and cost control
• Cross-functional leadership and alignment
• Accountability and performance management
• Systems thinking and process implementation
• Ability to operate effectively in fast-paced, evolving environments
• Confidence to make decisions and push back when required to protect business performance

What This Role Is Not

• This is not a purely technical engineering leadership role
• This is not a sales leadership role
• This is not a passive coordination position

This role is responsible for running the business on a day-to-day basis and ensuring execution across all functions.

What We Offer

• Competitive executive compensation package
• Comprehensive health and benefits plan
• Opportunities to work on complex, high-impact projects across multiple advanced industries
• A collaborative setting focused on accountability, execution, and continuous improvement
