Senior Software Engineer - Marketing Platform

Job Description

Wise is a global technology company, building the best way to move and manage the world’s money. Min fees. Max ease. Full speed. Whether people and businesses are sending money to another country, spending abroad, or making and receiving international payments, Wise is on a mission to make their lives easier and save them money. As part of our team, you will be helping us create an entirely new network for the world's money. For everyone, everywhere. More about our mission and what we offer. About the role: We're looking for a Senior Backend Engineer to build and scale Wise's price comparison platform. Comparison is about transparency—helping customers understand the real cost of sending money and why Wise is the better choice. You'll own the systems that collect pricing data from competitors and make it accessible across Wise, powering comparison tools and enabling data-driven decisions. This means building robust scrapers, reliable data pipelines, and APIs that teams depend on. Accuracy and trust are non-negotiable. You'll join the Marketing-Platform team in the Onboarding & Scalable Growth squad. We build the systems that unlock and optimise digital marketing and CRM, enabling £30+ million in marketing investment with proven ROI. What you’ll do: - Build the backbone: backend systems and APIs that power Wise’s comparison experiences. - Make scrapers feel “magical”: help define the roadmap for using LLMs and proven techniques to make data collection more stable, faster to evolve, and easier to scale. - Turn competitive pricing into a real-time advantage: expand and strengthen our competitive intelligence system across 100+ competitors in money transfer. - Obsess over data quality: build ingestion and validation pipelines with strong monitoring, accuracy checks, and rapid detection when the world changes. - Make data trustworthy by default: improve reliability, transparency and usability of marketing data so internal teams can move faster with confidence. - Design for scale: operate distributed, event-driven systems that stay reliable as volume and coverage grow. - Work like a small team building something big: collaborate daily with product, engineering, analytics and data partners to ship the right thing. - Own the whole experience: from shaping the solution to implementing, testing, releasing and watching it succeed in production. - Raise the bar: through great testing, thoughtful reviews, and feedback that makes the whole team better. Additional Information: For everyone, everywhere. We're people building money without borders — without judgement or prejudice, too. We believe teams are strongest when they are diverse, equitable and inclusive. We're proud to have a truly international team, and we celebrate our differences. Inclusive teams help us live our values and make sure every Wiser feels respected, empowered to contribute towards our mission and able to progress in their careers.
