About the role

BAS Controls Engineer
Position Overview: We are seeking a skilled BAS Controls Engineer to design, commission, and maintain building automation systems that optimize HVAC performance, energy efficiency, and occupant comfort. The role involves collaborating with mechanical and electrical teams, programming and troubleshooting controllers and field devices, and ensuring systems meet performance and regulatory requirements.
Key Responsibilities: Design, program, and configure Building Automation Systems (BAS) including controllers, field devices, and supervisory software. Commission, test, and troubleshoot HVAC controls and BAS installations to verify functionality and performance. Develop control sequences, logic diagrams, and point schedules to meet project specifications and energy optimization goals. Perform site visits to inspect equipment, collect data, and verify sensor/calibration accuracy. Collaborate with project engineers, contractors, and facility managers to integrate BAS with mechanical, electrical, and IT systems. Create and maintain system documentation including loop diagrams, wiring schematics, as-built drawings, and operation manuals. Provide training and technical support to commissioning teams, facility staff, and end users. Analyze system data and implement fault detection and diagnostics (FDD) and optimization strategies to improve system efficiency and reduce operating costs. Ensure compliance with applicable codes, standards, and cybersecurity best practices for building automation. Participate in pre-construction meetings, design reviews, and project handover activities to ensure seamless implementation.
Qualifications: Bachelors degree in Mechanical Engineering, Electrical Engineering, Controls Engineering, Building Systems, or related field, or equivalent experience.3+ years of experience designing, commissioning, or maintaining Building Automation Systems (BAS) and HVAC controls.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
