Company Description: Fit Collective - Albion-backed AI fashion startup fixing the $300B returns problem

Job Description: Join the team tackling fashion’s massive waste problem by building AI-powered co-pilots for production teams. You will develop customer-facing web apps, e-commerce integrations, and self-service onboarding platforms using TypeScript and Python. This role is perfect for a product-minded engineer who wants to build high-impact tools that directly reduce global carbon emissions and textile waste.

Location: London, UK

• Join a high-growth startup that recently closed the UK’s largest female-founded pre‑seed ($4M) led by top-tier investors Albion and SuperSeed.
• Work in a high‑ownership environment with a modern stack (FastAPI, React, Snowflake) where your code directly influences product direction and sustainability goals.

What you will do:

• Develop the AI pre-production co-pilot interface that guides designers through the creation process to prevent fit issues before manufacturing.
• Build and maintain robust e-commerce integrations and plugins that deliver real-time, personalized size recommendations to shoppers on platforms like Shopify.
• Architect and scale the customer onboarding platform, enabling fashion brands to seamlessly connect PLM and returns data via self‑service flows.

The ideal candidate:

• Has 3+ years of professional experience with TypeScript and Python, building and maintaining production-grade systems in cloud-native environments like AWS.
• Possesses strong frontend expertise in React with the ability to create polished, responsive interfaces that simplify complex data for end-users.
• Exhibits a startup-ready mindset with a track record of shipping pragmatic solutions quickly and taking full ownership of features from ideation to deployment.
