Full job description

What is Stora?

Stora is on a mission to reinvent self-storage through technology. Our platform helps operators run their businesses more efficiently, automate the day-to-day, and unlock new revenue opportunities.

In just over five years, we’ve helped more than 450 operators process tens of millions in automated payments. We’re recognised as innovators in our space, and we’re a fast-growing, product-led team focused on making self-storage better for everyone.

Why Join Us?

We believe senior engineers should have room to lead, not just code.

At Stora you’ll:

Set the direction — help shape our product, architecture, and engineering practices.
Lead by example — deliver high-quality features while mentoring and supporting others.
Work with impact — your ideas won’t get lost in a committee; you’ll see them live in production, helping real businesses every day.
Stay hands-on — we value technical leadership that’s grounded in active coding and problem-solving.

We value honesty, humility, and responsibility — and we give everyone the trust and autonomy to own their role.

About the Role

You’ll join a small, passionate team of Rubyists, taking ownership of complex projects from concept to deployment. Alongside writing maintainable, well-tested code, you’ll help define technical direction, guide architectural decisions, and mentor engineers as we scale.

Our work spans diverse domains including billing, CRM to public APIs, reporting, integrations, and internal tooling

You’ll have the freedom to specialise or lead initiatives in the areas that interest you most. We’re pragmatic, not dogmatic — we balance moving fast with building for the long term.

Your Responsibilities

Lead the design and development of complex features from concept to deployment.
Collaborate with product and stakeholders to define scope, refine requirements, and ensure solutions meet business goals.
Make sound architectural decisions to keep our Rails app maintainable, performant, and scalable.
Dedicate time (at least 20%) to improving stability, performance, and developer experience.
Maintain a strong automated test suite so we can confidently deploy to production multiple times per day.
Proactively monitor, investigate, and resolve production issues, driving preventative improvements.
Mentor and support engineers through code reviews, pairing, and knowledge sharing.

Our Technology Stack

We take a majestic monolith approach — keeping our Rails app clean, cohesive, and aligned with Ruby community best practices.

Backend: Rails 8, PostgreSQL, Redis, Sidekiq, TimescaleDB
Frontend: Turbo 8, targeted React for richer UI, ViewComponents, Sass, BEM methodology
Testing: Minitest, Capybara, Playwright
Payments: Stripe Connect and Billing
Deployment: GitHub Actions, Heroku

What We’re Looking For

Proven track record designing, building, and scaling production Rails applications.
Strong command of Rails fundamentals — ActiveRecord, background jobs, request/response cycle — and how to apply them effectively.
Experience architecting maintainable systems that balance speed of delivery with long-term sustainability.
Comfortable working across the stack, including frontend technologies (JavaScript, CSS).
Skilled at using modern LLM-powered tools to accelerate work and explore solutions — with the judgement to know when to rely on your own expertise.
Strong testing mindset, with hands-on experience in Minitest or RSpec.
Confident debugging and resolving complex production issues.
Skilled mentor with the ability to grow and support other engineers.
Clear communicator, able to articulate technical challenges, trade-offs, and decisions.

Benefits & Compensation

Competitive annual salary – starting from £75k DoE
Remote Work Option – Can be fully remote within the UK or EU only. Candidates must be based in either the United Kingdom or the European Union
Office Access – Use of office in Belfast for those who live locally
Health & wellness – Private health insurance for you and your family
Retirement – Company pension plan
Leave – 35 days paid annual leave
Professional growth - L&D support
Share options
WFH budget
Company-wide social events

Next steps

We’re reviewing applications as they come in and will be in touch quickly if it looks like a match.
