• Design and document mechanical systems for mission critical facilities and data centers, including HVAC, cooling systems, plumbing, and building automation/control systems.
• Support the development of resilient and energy-efficient infrastructure for high-performance facilities with a focus on uptime, redundancy, and operational continuity.
• Produce drawings, specifications, diagrams, 3D models, sequences of operation, and technical reports aligned with project goals and client expectations.
• Perform engineering calculations including cooling load analysis, energy modeling, airflow analysis, equipment sizing, and system redundancy evaluations.
• Coordinate closely with electrical engineers, technology consultants, and architects to integrate cooling and infrastructure systems into mission critical environments.
• Apply building codes, ASHRAE standards, energy codes, and industry best practices to deliver compliant and functional solutions.
• Participate in client meetings, technical design reviews, and multidisciplinary coordination efforts.
• Collaborate with internal teams, consultants, contractors, and owners to deliver integrated project outcomes.
• Support QA/QC efforts and construction administration activities, including submittal reviews, RFIs, commissioning coordination, and site observations.
• Lead project documentation efforts, mentor junior staff, and oversee project deliverables (mid- and senior-level roles).

Soft Skills

• Strong communication and collaboration skills across disciplines and with clients.
• Critical thinking and creativity in solving complex infrastructure and design challenges.
• Adaptability and organization in a fast-paced, technically demanding environment.
• Mentorship mindset with a willingness to guide and support junior engineers.
• Strong written and verbal communication skills with attention to technical clarity and detail.
• Initiative in identifying innovative solutions and improving design and workflow efficiencies.
• Interest in emerging technologies, sustainability, and mission critical engineering trends.
