Senior Software Engineer (Product)

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.

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.

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.
