Founding Engineer - Software

You're building the software that makes traditional engineering workflows obsolete.

Aran is automating the design and engineering of data centers and industrial megaprojects. Our engineers are building parametric engines that turn physical constraints into complete engineering deliverables. Your job is to make these engines work together as one coherent platform.

You'll work directly with engineers who understand the physics and help translate their knowledge into reliable, scalable software. You'll own everything from computational engines and AI agents to the interfaces our engineers and customers use.

This isn't a role where you build dashboards around an LLM. You're building software that designs things that actually get constructed.

What you’ll achieve

• Build the core engineering platform connecting civil, structural, mechanical, electrical, and architectural design.
• Develop parametric models, computational geometry systems, dependency graphs, and automated engineering workflows.
• Build AI agents that can reason across engineering documents, drawings, calculations, specifications, and design constraints.
• Create workflows that transform project requirements into coordinated 3D models, engineering calculations, and construction documentation.
• Build robust interfaces and infrastructure that make complex engineering accessible, auditable, and repeatable.
• Ship production software continuously, working directly with domain engineers and customers.

Requirements

• You must
• Be an exceptional software engineer who has built and shipped real products end-to-end.
• Understand systems deeply — data structures, algorithms, architecture, and how to make complex software reliable.
• Be comfortable working across the stack, from backend systems and computational engines to user-facing products.
• Be highly proficient with AI coding agents and capable of moving dramatically faster because of them.
• Have the curiosity to learn engineering fundamentals, physical constraints, and how the built world works.
• Take full ownership of problems. You don't wait for detailed specifications before building.
• You do not need to Have a background in civil, mechanical, electrical, or structural engineering.
• Have worked in construction or data centers.
• Have a specific degree or pedigree.
• Know every framework or programming language.
• Experience with computational geometry, CAD/BIM, simulation, physics engines, developer tools, or complex technical software is particularly interesting.
