About the Job

Requirements

Understand heat transfer, fluid dynamics, thermodynamics, and cooling-system trade-offs deeply.
Have hands-on experience building real physical systems, ideally first-of-a-kind products.
Be able to ship code using AI tools, even without a traditional software background.
Be capable of taking a difficult engineering problem from first principles to a working solution.

Responsibilities

Deliver complete mechanical and HVAC packages, including cooling-load calculations, airflow and computational fluid dynamics analysis, chilled-water and liquid-cooling architectures, equipment sizing, piping and instrumentation diagrams, 3D models, and construction sets.
Build a parametric thermal and HVAC engine that generates deliverables from one parameter template for any data center site.
Automate system sizing, equipment selection, thermal calculations, and design optimization.
Connect mechanical designs with electrical and structural systems so changes automatically propagate across disciplines.
Use AI coding agents such as Claude Code to build workflows and ship code.

Desired Qualifications

A professional engineer license is helpful but not required.
Prior software experience, a computer science degree, direct data-center experience, construction experience, or architecture, engineering, and construction experience is not required.

Founding Member of Technical Staff - Thermal / HVAC / Mechanical Engineer

Aran Industries · United States (Remote) · Full-time · Posted 2026-10-15

Salary: USD 150,000–250,000

Workplace: remote

Department: Mechanical

Description

You own end-to-end thermal and HVAC design automation for data center and industrial projects — from air-cooled halls to liquid cooling.

You'll deliver real mechanical engineering on live projects while building the parametric engine that generates those designs for every future site.

You don't need prior software experience. Our engineers who've never shipped software products are writing code with AI every day. What matters is that you understand the physics, the constraints, and the trade-offs — and that you build.

What you’ll achieve

Deliver complete mechanical/HVAC packages: cooling load calculations, airflow and CFD analysis, chilled-water and liquid-cooling architectures (direct-to-chip, immersion, rear-door, CDUs), equipment sizing, P&IDs, 3D models, and construction sets.
Build a parametric thermal/HVAC engine that generates these deliverables from a single parameter template for any data center site.
Automate system sizing, equipment selection, thermal calculations, and design optimization.
Connect mechanical designs with electrical and structural systems so changes automatically propagate across disciplines.
Use AI coding agents (Claude Code and similar) to build these workflows. You will ship code.

Requirements

You must

Understand the physics deeply — heat transfer, fluid dynamics, thermodynamics, and cooling-system trade-offs.
Have built real physical systems hands-on, ideally first-of-a-kind products at companies like Tesla, SpaceX, Joby, Anduril, Rivian, or similar environments.
Be able to ship code with AI tools today, even without a traditional software background.
Be capable of taking a difficult engineering problem from first principles to a working solution.
Be someone your current employer would be upset to lose.

You do not need to

Hold a PE license (helpful, not required).
Have a CS degree or identify as a software engineer.
Have direct experience in data centers, construction, or AEC.
Believe that AI should replace engineering judgment. We don't.

Benefits

Full-time | Remote (US or Canada, excluding Quebec) | US$150k–$250k or CA$215k–CA$355k base + founding-team equity

Fully compensated health plans with 100% dependent coverage.

We hire across the experience spectrum. Proof that you build beats years on a resume.

About the Company

Aran Industries

Global bag-in-box liquid packaging manufacturer

Aran Industries makes Bag-in-Box liquid packaging for the liquid food, industrial, and institutional markets. It produces aseptic and non-aseptic flexible bags from multi-layer films (some with oxygen barriers) for liquids from 1 to 1,500 liters. The bags fit inside a rigid outer carton and use thermo-lamination to improve recyclability, while the system cuts plastic use by up to 80% and lowers transportation costs, helping extend shelf life. With facilities in Israel, Spain, and the USA, it serves 45+ countries and differentiates itself through a global footprint, sustainability efforts, and a broad product range for many liquids, aiming to provide cost-effective, scalable packaging that protects quality and reduces material and logistics costs for customers.
