Senior Product Software Engineer – Merchant Experience

• Experience with Ruby on Rails and/or React.

• Strong full-stack experience.

• Experience building platforms or capabilities used by other teams.

• Experience with product discovery, experimentation or success metrics.

• Spanish fluency.

We're looking for a Senior Product Builder who wants to own product problems, not just engineering tasks.

You'll work across the full lifecycle of B2B initiatives:

seQura provides innovative, flexible and easy-to-use payment technologies that help merchants acquire, convert and retain more customers.

We make a difference in sales performance by tailoring our solutions to different sectors, to address their unique pain points and deliver superior results in Retail, Education, Eyewear, Repairs and Travel.

We also empower smart shopping to consumers who seek more value, convenience, and flexibility in their shopping, with new payment experiences that allow them to save, access interest-free credit, or pay in small, comfortable installments of up to 24 months.

Born in Barcelona, seQura is a privately-owned fintech, currently expanding throughout southern Europe and Latin America, growing above 50% CAGR.
Over 6000 businesses, almost 3 million shoppers, and almost 400 employees continue to rate us as one of the most loved and trusted fintechs out there, with an NPS of 87%, a Trustpilot rating of 4.7/5, and a Glassdoor rating of 4.1/5.

This is not a frontend or backend-specific role. Our main stack is Ruby on Rails and React, but we care more about strong engineering fundamentals, product judgment and the ability to work across the stack when needed.

You won't receive a perfectly specified backlog. You'll be expected to help create the work: understand merchants and the business, challenge assumptions, work through ambiguity and decide with the team what is worth building.

• Own product initiatives end-to-end, from problem understanding to outcome validation.

• Act as Champion for initiatives: gather context, define hypotheses and success criteria, shape the work and drive it forward.

• Work directly with merchants, business stakeholders, Product Design and other engineering teams when needed.

• Build and operate production software across backend and frontend.

• Make pragmatic product and technical decisions with incomplete information.

• Use data, feedback and experiments to decide whether to iterate, change direction or stop.

• Contribute to evolving Merchant Portal into a platform other B2B teams can build on.

• Use AI throughout your workflow, including exploration, implementation, testing, debugging and learning unfamiliar systems.

Learn the B2B domain, Merchant Portal, codebase and current initiatives. Shadow a Champion, meet key stakeholders and start contributing.

Own a small initiative with support from the team, from understanding the problem to shipping it.

Act as Champion for an initiative: frame the problem, define the hypothesis and success criteria, ship a solution and check the outcome.

• 7+ years of experience building production software.

• Strong software engineering fundamentals.

• Experience owning work beyond implementation.

• Comfortable working across backend and frontend when needed.

• Comfortable working with ambiguity and incomplete information.

• Strong product and customer curiosity.

• High autonomy, ownership and accountability.

• Comfortable working directly with stakeholders and other teams.

• Experience using AI meaningfully in your software development workflow.

• Strong written and verbal communication skills in English.
