About the Role

This startup is building a cutting‑edge platform to transform how engineers design physical products. Instead of creating one solution at a time, this system enables users to generate, visualise, and explore thousands of design alternatives – faster and more intelligently than ever before.

This company is a spin‑out from one of the UK’s most successful startups, built by top‑tier engineers and developers from industry‑leading teams. We’re looking for a software engineer who enjoys writing clean, functional code and is genuinely passionate about real‑world engineering, not just building software but helping change how things are designed and built.

Tech Stack within the engineering environment:

• Paradigms: event‑driven architecture

Responsibilities

• Build and maintain backend services using FastAPI and Python for geometry, simulation, and data workflows
• Work closely with domain experts (engineers, designers) to translate complex physical problems into usable software features
• Follow functional programming practices to write testable, composable code
• Own features from idea to implementation to deployment
• Contribute to architectural decisions in a fast‑moving, early‑stage product

Requirements

• Bachelor’s degree in Computer Science, Engineering, Physics, Mathematics, or a related technical field
• 2+ years of experience building web applications in a production environment
• Strong experience with Python and API frameworks (FastAPI, Flask, etc.)
• Comfort or interest in functional programming principles and clean code architecture
• A genuine interest in engineering and the physical world
• Ability to thrive in a startup or agile environment with autonomy and ownership
