Senior Software Engineer (Product)

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 highquality 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 handson — we value technical leadership that’s grounded in active coding and problemsolving.

• 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, welltested 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.
