Full-Stack Ruby on Rails Engineer (Waste Start)

About Us 

WasteStart is building a modern ERP platform for the waste industry. We've recently completed a successful seed funding round and are growing our team. 

Our mission is to help waste and recycling companies run more efficiently through better software — and support them on their journey to leverage AI and data more effectively in day-to-day operations. 

We work hybrid-first, with a Glasgow HQ available for team collaboration. 

What You’ll Do 

You’ll join a small, experienced team working directly with customers to design, build, and improve the core WasteStart platform. You’ll have ownership from top to bottom — UI to database — and be involved in product thinking, not just implementation. 

Expect to: 

• Build and ship new features in our Rails 8 app using Hotwire, Stimulus, and Turbo Native 
• Work closely with customers and the team to understand workflows and design solutions 
• Own the features you build — from design and testing through to deployment and feedback 
• Help us improve our architecture, developer experience, and internal tooling as we grow 

Our Stack

• Ruby on Rails 8 
• Hotwire (Turbo, Stimulus, Turbo Native) 
• PostgreSQL 
• TailwindCSS 
• ViewComponent 
• Minitest 
• GitHub, CI/CD pipelines, and modern dev workflows 

Who We’re Looking For 

You don’t need to tick every box, but you might be a good fit if you: 

• Have solid experience with Ruby on Rails and enjoy working across the full stack 
• Are comfortable building modern UIs with Hotwire and Stimulus (or excited to learn) 
• Care about building great user experiences and value customer feedback 
• Take ownership and pride in what you build — from the database to the button click 
• Prefer working in a small, fast-moving, product-focused team 
• An interest in developing solutions that allow our customers to leverage AI in a meaningful and useful way 
• Are curious about how AI can support your development work — and are excited to use it to augment your skills, not replace them 

Nice to Haves 

• Experience with mobile apps (especially Turbo Native) 
• Background in B2B or ERP-style products 
• Interest in the environmental or waste sectors 

Why Join WasteStart? 

• Be part of a purpose-driven company modernising a neglected industry 
• Shape a product early in its lifecycle 
• Work closely with customers, not just specs 
• Use modern dev tools and AI-assisted workflows 
• Hybrid work environment with an office in Glasgow 
• Competitive salary and flexibility 

Interested? 
We’d love to hear from you.
