Junior Full-Stack Engineer

Hybrid (Glasgow HQ) | Full-time

About Us

We’re building a modern ERP platform for the waste industry. Following a successful seed funding round, we’re expanding our engineering team and looking for a junior to early-career engineer who wants to deepen their skills while working on a real, customer-facing product.

Our mission is to help waste and recycling companies run more efficiently through smarter software — and to support them in leveraging AI and data in everyday operations.

We’re a hybrid team with a central Glasgow HQ for collaboration, learning, and shared problem-solving.

What You’ll Do

You’ll join a small, experienced engineering team and contribute to production features across the full stack. You’ll work with support and mentorship, while being trusted to own parts of features and gradually take on more responsibility.

Your role will include:

Building and improving features in our Rails 8 application using Hotwire, Stimulus, and Turbo Native

Working with teammates and customers to understand workflows and turn requirements into solutions

Owning smaller features or components end to end, from implementation through testing and release

Contributing to code quality, testing, and maintainability as the product evolves

Learning and applying modern development practices, including CI/CD and AI-assisted workflows

Our Stack

Ruby on Rails 8

Hotwire (Turbo, Stimulus, Turbo Native)

PostgreSQL

TailwindCSS

ViewComponent

GitHub with CI/CD pipelines

Who We’re Looking For

This role is suited to engineers with around 1–3 years of professional experience who are ready to grow. You might be a great fit if you:

Have commercial experience working with Ruby on Rails

Are comfortable working across backend and frontend code, or keen to build that confidence

Have some experience with testing, version control, and team-based development

Care about building reliable, user-friendly software and learning from feedback

Enjoy working in a small, product-focused team where your contributions are visible

Are curious about how AI can support software development and customer workflows

Nice to Haves

Experience with Hotwire, Stimulus, or similar frontend patterns

Exposure to B2B, SaaS, or ERP-style products

Experience working directly with non-technical stakeholders or customers

An interest in sustainability, environmental tech, or the waste sector

Why Join?

Clear progression from junior to mid-level as the product and team grow

Meaningful ownership without being thrown in at the deep end

Modern Rails stack with room to learn and influence technical direction

Close collaboration with customers and experienced engineers

Hybrid working with a Glasgow office for team time and support
