Airswift is seeking a Mechanical Engineer to support the data center industry in an initial 6-month contract.
We are seeking a Senior Mechanical Engineer to lead the design and delivery of critical mechanical systems for high-density data centers, including both conventional air-cooled facilities and direct liquid cooling (DLC) environments. This role ensures the safe, efficient, and resilient operation of cooling and mechanical infrastructure. From chillers to fan wall, CRAC/CRAH units, CDU loops and rack-level liquid cooling; enabling next-generation compute platforms and mission-critical operations. The ideal candidate brings a proven track record in mechanical design for data centers and thrives in collaborative, fast-paced, multidisciplinary projects.
Responsibilities:
- Mechanical System Design & Engineering
- Develop detailed designs for mechanical and cooling systems (chillers, cooling towers, CRAC/CRAH units, pumps, piping, valves, CDUs, FW, RDHx, and DLC loops).
- Define control strategies for primary and secondary cooling loops, supporting both air and DLC environments.
- Produce design documentation including schematics, layouts, hydraulic diagrams, specifications, and equipment schedules.
- Evaluate and select equipment suppliers, ensuring compliance with project performance requirements and client standards.
- Thermal Performance & Analysis
- Perform load calculations, hydraulic modeling, and energy efficiency analysis.
- Optimize chilled water, glycol, and DLC systems to meet PUE and WUE targets.
- Assess redundancy schemes (N, N+1, 2N) and their impact on system performance and resilience.
- Integrate mechanical design with electrical and IT infrastructure, ensuring alignment across disciplines.
- Commissioning & Delivery
- Support procurement processes, technical reviews, and submittal evaluations.
- Oversee factory acceptance tests (FATs), site acceptance tests (SATs), commissioning, and system validation
- Lead troubleshooting and root cause analysis for thermal or mechanical issues, implementing corrective actions.
- Compliance & Documentation
- Ensure designs comply with international standards, local building codes, ASHRAE, and Uptime Institute best practices.
- Develop and maintain documentation including test protocols, O&M manuals, and method statements.
- Contribute to risk assessments and ensure safety compliance for fluid handling systems.
- Collaboration & Expertise
- Partner with clients, architects, electrical engineers, and IT teams to deliver integrated solutions.
- Provide subject matter expertise on highdensity and DLC cooling strategies.
- Mentor junior engineers and contribute to knowledge sharing within the organization.
Skills & Competencies:
- Bachelor’s or Master’s degree in Mechanical Engineering (or related field).
- Minimum 7 years of experience in mission-critical mechanical design, with demonstrable data center project delivery.
- Strong knowledge of HVAC, chilled water, and liquid cooling systems (DLC, CDU, RDHx, etc.).
- Proficiency in mechanical design and analysis tools (e.g., Revit, AutoCAD MEP, HAP, Pipe-Flo, CFD).
- Familiarity with Tier certification requirements, ASHRAE guidelines, and international standards.
- Proven analytical, problem-solving, and troubleshooting skills.
- Strong communication and collaboration skills in cross-disciplinary teams.
- Ability to manage complex projects under tight deadlines in client-facing environments.
