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. The Design Engineer works closely with mechanical, electrical, software, and commissioning teams to translate system requirements and sequences of operation into clear, buildable designs that meet project specifications, industry standards, and performance goals.

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.
• Assist 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.
