Computer Science Co-Op

WHY JOIN CRITICAL ENVIRONMENT?

Help us make safer air available everywhere

Critical Environment Technologies (CET) is the largest independent commercial gas-detection manufacturer in North America. We design, manufacture, and service gas-detection systems that integrate with HVAC and building automation and controls systems across commercial, institutional, municipal, and industrial applications - from parking facilities and refrigeration plants to arenas, wineries, swimming pools, and water-treatment facilities.

Our products are used across every US state and Canadian province and in more than 20 countries. Continued investment in research and development keeps our equipment and our people at the leading edge of a rapidly evolving industry.

Our mission, Safer Air Everywhere, has never been more important. It guides how we develop products, serve customers, protect the environment, and work together.

We’re a growing, collaborative team where people are encouraged to take ownership, contribute ideas, and make a meaningful impact. Our culture is built around five straightforward values:

• Stay curious. 

• Give a sh*t about our work and each other. 

• Get things done. 

• Maintain a positive attitude. 

• Act with integrity.

• Contribute to front-end development using React or React Native (or similar frameworks) 

• Write clean, efficient, and maintainable code following best practices 

(ii) Testing & Documentation

• Participate in software testing, debugging, and validation 

• Document development processes, design decisions, and testing outcomes 

(iii) Collaboration

• Work closely with hardware and firmware engineers to ensure seamless integration between systems 

• Participate in sprint reviews and team meetings, providing input and ideas for improvement 

REQUIRED EXPERIENCE:

• Self-starter who enjoys learning new technologies and working with AI-driven workflows 

• Currently enrolled in a Computer Engineering, Computer Science, Software Engineering, or related co-op program 

• Hands-on experience using AI-assisted software development tools (e.g. Lovable, or similar) 

• Familiarity with React, React Native, or similar front-end frameworks 

• Understanding of modern web development (HTML, CSS, JavaScript/TypeScript) 

• Exposure to modern cloud platforms and AI-enabled tooling (Cursor, Supabase, Vercel, etc.) 

• Experience integrating AI into development workflows, such as code generation, refactoring, debugging, testing, or documentation 

• Solid problem-solving and analytical skills 

• Strong communication and collaboration abilities 

WHAT WE OFFER:

• An attractive hourly wage of $21 per hour 
• An opportunity to make an outsized contribution along with a great team and company culture
