Hybrid Building Automation / HVAC Controls Design Engineer

About the role

The Design Engineer supports the design, documentation, and implementation of building automation and control systems for commercial, industrial, and mission-critical facilities. This role focuses on developing accurate and well-coordinated control system designs under the guidance of senior engineering staff and project managers.

Key Responsibilities

• Develop HVAC and building automation control system designs, including control schematics, network/riser diagrams, panel layouts, and point-to-point wiring details.
• Interpret mechanical and electrical drawings, specifications, and sequences of operation to produce complete and coordinated control designs.
• Absorb assistance with the preparation of control submittals, bills of materials (BOMs), and device schedules for procurement and fabrication.
• Apply established engineering standards, codes, and best practices (e.g., NEC, NFPA, ASHRAE, UL) with guidance from senior engineers.
• Participate in QA/QC reviews by responding to comments and revising drawings, submittals, and as-built documentation.
• Support commissioning and startup activities by coordinating with software and field teams and assisting with troubleshooting controls or networking issues.
• Draft sequences of operation, control narratives, and basic logic diagrams for HVAC and integrated building systems.
• Assist in the design of system architectures utilizing BACnet, Modbus, and IP-based communication networks.
• Support control panel design efforts, including layout development and review of panel shop drawings.
• Help evaluate control hardware, sensors, and system configurations to support performance and energy efficiency goals.
• Collaborate with cross-functional teams to resolve design issues and maintain project schedules.
• Follow internal CAD standards, documentation guidelines, and engineering workflows.

Qualifications

• 2–5 years of experience in building automation systems (BAS), controls engineering or industrial controls.
• Working knowledge of AutoCAD or AutoCAD Electrical and experience producing control drawings and documentation.
• Familiarity with building automation communication protocols such as BACnet, Modbus, or LonWorks.
• Understanding of DDC system components, field controllers, point mapping, and HVAC control concepts.
• Basic knowledge of sequences of operation, mechanical system integration, and electrical fundamentals.
• Awareness of applicable codes and standards including NEC, NFPA, UL, and ASHRAE.
• Strong attention to detail, organizational skills, and written and verbal communication abilities.
• Ability to learn from senior engineers and apply feedback effectively.
