About Submer

Submer designs and delivers end-to-end AI datacenter infrastructure built around industry-leading liquid cooling.

We help organizations scale AI beyond the limits of traditional datacenters by enabling higher density, greater efficiency and lower environmental impact – accelerating time-to-AI from first deployment to full production.

What impact you will have

We are seeking a CSA Engineer to lead and deliver all Civil, Structural, and Architectural scopes for a next-generation data center featuring high-density AI/HPC workloads and DLC cooling systems. The role ensures structural integrity, constructability, code compliance, architectural coordination, and seamless integration of CSA works with MEP, IT/OT, equipment installation, and commissioning activities. 

What you’ll do

1. Civil, Structural & Architectural Design

• Design and review foundations, slabs, steel structures, equipment pads, and building systems.

• Perform key structural calculations (gravity, seismic, wind, dynamic loads).

• Define architectural layouts, fire separations, building envelope, and space optimization.

2. Multidisciplinary Design Coordination

• Coordinate CSA scope with Mechanical and Electrical teams (penetrations, supports, clearances).

• Participate in design reviews, clash detection, and constructability assessments.

• Support value engineering while maintaining performance and reliability.

3. Code Compliance & Permitting

• Ensure compliance with applicable building codes (IBC, NFPA, ASCE) and AHJ requirements.

• Support permitting submissions and inspections.

4. Construction & Field Engineering Support

• Provide onsite support for CSA works (foundations, steel, envelope, architectural finishes).

• Review shop drawings, RFIs, and material submittals.

• Inspect concrete, steel, waterproofing, firestopping, and architectural systems.

5. Commissioning, Handover & Quality

• Support CSA commissioning readiness and punch-list completion.

• Verify anchorage, fire barriers, egress routes, and as-built documentation.

• Contribute to QA/QC, risk mitigation, and safety compliance.
  

What you’ll need

• Bachelor’s or Master’s degree in Civil Engineering, Structural Engineering, Architecture, or related field. 

• 4+ years of CSA experience in mission-critical, industrial, or data center environments. 

• Strong knowledge of IBC, ASCE, ACI, AISC, NFPA, ADA, and related standards. 

• Experience coordinating CSA works with MEP disciplines. 

• Ability to support fast-track construction environments and resolve field issues efficiently. 

Nice to have:

• Experience with high-density or AI/HPC data center projects. 

• Familiarity with DLC system structural/architectural considerations. 

• Familiarity with Tier standards such as Uptime Institute or TIA-942. 

• Experience working in overlapping design–construction delivery models. 

What we offer

• Attractive compensation package reflecting your expertise and experience.

• Restaurant Pass.

• Private Health Insurance.

• Languages classes (English).

• A healthy work environment with fresh fruits to energise and an on-site gym for active breaks.

• A great work environment characterized by friendliness, international diversity, flexibility, and a hybrid-friendly approach.

• You'll be part of a fast-growing scale-up with a mission to make a positive impact, offering an exciting career evolution.
