Job summary

Aran Industries seeks a leader to drive thermal and HVAC design delivery for data center and industrial projects, including air‑cooled and liquid‑cooling systems. You will develop a parametric engine to generate designs and documentation and ship code using AI tools.

You will deliver mechanical packages, automate sizing and thermal calculations, and coordinate with electrical and structural teams to ensure coherent, cross‑disciplinary designs.

Qualifications

• Deep understanding of heat transfer, fluid dynamics, thermodynamics and cooling-system trade-offs.
• Hands-on experience taking engineering problems from first principles to working solutions.
• Ability to write and ship code with AI tools; traditional software background not required.
• Strong engineering judgement balancing physical constraints with design requirements.

Responsibilities

• Produce mechanical and HVAC packages including cooling loads, airflow and CFD analyses, chilled-water and liquid-coooling systems, equipment sizing, P&IDs, 3D models and construction sets.
• Build a parametric engine that generates design deliverables from project parameters.
• Automate equipment selection, system sizing, thermal calculations and design optimization.
• Coordinate mechanical designs with electrical and structural systems to propagate changes across disciplines.
• Use AI coding agents to build and ship engineering automation workflows.

Job description

Role overview

Lead thermal and HVAC design delivery and automation for data center and industrial projects, spanning air‑cooled environments and liquid‑cooling systems. You’ll deliver mechanical engineering for active projects while building a parametric engine to generate designs and documentation for future sites. The role combines hands‑on engineering judgment with developing and shipping code using AI tools.

Responsibilities

• Produce mechanical and HVAC packages covering cooling loads, airflow and CFD analysis, chilled‑water and liquid‑cooling systems, equipment sizing, P&IDs, 3D models, and construction sets.
• Build a parametric engine that generates design deliverables from a shared set of project parameters.
• Automate equipment selection, system sizing, thermal calculations, and design optimization.
• Connect mechanical designs with electrical and structural systems so changes can propagate across disciplines.
• Use AI coding agents to build and ship engineering automation workflows.

Requirements

• Deep understanding of heat transfer, fluid dynamics, thermodynamics, and cooling‑system trade‑offs.
• Hands‑on experience building real physical systems and taking engineering problems from first principles to working solutions.
• Ability to write and ship code with AI tools; a traditional software background is not required.
• Strong engineering judgment and an ability to balance physical constraints with design requirements.

Nice to have

Experience developing first‑of‑a‑kind physical products or systems. A PE license is helpful but not required. Prior data center, construction, or architecture, engineering, and construction experience is not required.

Benefits and work setup

Full‑time, remote work from the US or Canada, excluding Quebec. The role includes founding‑team equity, fully covered health plans with dependent coverage, and a base salary range of US$150,000–$250,000 or CA$215,000–$355,000.
