About Submer
At Submer, we are redefining how data centers are built, integrated, and operated, with sustainability, efficiency, and innovation at the core. Our technology is designed to reduce environmental impact while improving performance and efficiency. We are a purpose-driven company with a passion for innovation and a growing global presence.
What impact you will have
You will lead the design, analysis, and optimization of mechanical building systems for mission-critical facilities, including data centers, technical spaces, and high-performance infrastructure projects. You will be responsible for HVAC, hydronic systems, ventilation, piping, and mechanical utilities, ensuring designs meet performance, efficiency, safety, and code requirements.
This role reports to the Director of Engineering and supports both new construction and retrofit projects, from conceptual design through commissioning.
What you'll do

• Lead MEP mechanical system design for HVAC, chilled water systems, air distribution, ventilation, and other mechanical building systems for mission-critical facilities.
• Develop technical specifications, load calculations, mechanical layouts, 3D models, and construction drawings in accordance with project requirements and industry standards.
• Perform thermal load calculations, fluid flow analysis, and equipment sizing (chillers, pumps, CRAHs/CRACs, heat exchangers, piping networks, etc.).
• Ensure designs comply with relevant codes and standards (ASHRAE, IMC, IPC, NFPA, local building codes).
• Collaborate closely with electrical, structural, controls, and architectural teams to integrate mechanical systems into coordinated facility designs.
• Review and support submittals, shop drawings, procurement packages, and equipment selections.
• Oversee field investigations, site surveys, construction support, and commissioning for mechanical systems.
• Troubleshoot and optimize mechanical systems during start-up, testing, and operational phases.
• Mentor junior mechanical engineers, conducting technical reviews and providing guidance on best practices.
• Support continuous improvement of internal design standards, QA/QC procedures, and documentation.
• Assess and evaluate emerging HVAC and mechanical technologies to improve efficiency, sustainability, and resiliency in facility designs.

What you'll need

• Bachelor's degree in Mechanical Engineering or a related field.
• 8+ years of MEP mechanical engineering experience, preferably in data centers, industrial facilities, commercial buildings, or other mission-critical environments.
• Strong knowledge of HVAC design, hydronic systems, air distribution, and mechanical utilities.
• Proficiency in MEP design tools and CAD platforms (AutoCAD, Revit, SolidWorks, or similar) and engineering analysis software (e.g., Trace, HAP, CFD tools).
• Solid understanding of ASHRAE standards, mechanical codes, and MEP best practices.
• Experience with construction administration, field inspections, and commissioning.
• Strong analytical, problem-solving, and communication skills.
• Experience leading small teams or mentoring junior engineers.

What we offer

• Attractive compensation package refleting your expertise and experience.
• A great work environment characterised by friendliness, international diversity, flexibility, and a hybrid-friendly approach.
• Youll be part of a fast-growing scale-up with a mission to make a positive impact, offering an exciting career evolution.
