Job description

Back End Engineer

Location: London, UK (Hybrid)

Type: Full-time

Level: Mid to Senior

Company: Tiro Partners Limited

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 start‑ups, 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: 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.
