Overview

Stora is hiring a Senior Software Engineer (Product) in Belfast, Northern Ireland, United Kingdom. You will join a small, passionate team of Rubyists, taking ownership of complex projects from concept to deployment.

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 will be visible in production and help real businesses every day.
• Stay hands-on — technical leadership 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 domains including billing, CRM, 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 — balancing speed with long-term sustainability.

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.

• Backend: Rails 7.1, PostgreSQL, Redis, Sidekiq, TimescaleDB
• Frontend: Turbo 8, targeted React, ViewComponents, Sass, BEM
• Testing: Minitest, Capybara, Selenium
• Payments: Stripe Connect and Billing

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.

• Office Access – Use of office in Belfast for those who live locally.
• Health & wellness – Private health insurance for you and your family.
