Ingénieur(e) de données principal(e) | Senior Data Engineer

Valsoft Corporation; Sint-Laureins; On-site; EUR 69,000 - 87,000; Full time

Job summary

Valpay is seeking a Senior Data Engineer to design, build, and operate the data platform that underpins analytics, reporting and product decisions. You will ensure the data is reliable, accessible, and trusted as it flows through payments data and AI features.

This on-site Montreal-based team collaborates across Engineering, Product, Finance and Growth Pods to tackle complex data problems with scalable pipelines and a robust semantic layer in Snowflake.

Responsibilities

• Design, build and maintain scalable data pipelines and ELT/ETL processes across both batch and streaming workloads.
• Model and optimize Snowflake warehouse with dimensional models, dbt transformations, and the semantic layer that analytics and product teams build on.
• Build the data foundations for payments reporting: transaction lifecycle, settlement and reconciliation, merchant performance and partner revenue.
• Own data quality, integrity, lineage and observability. You'll define what "trustworthy" means here and build the tooling that proves it.
• Improve the performance, reliability and cost efficiency of the platform as transaction volumes grow.
• Prepare and serve data for AI and LLM use cases — clean, well-documented, well-governed datasets that internal AI tools and customer-facing features can depend on.
• Partner with stakeholders across the business to turn open-ended questions into well-scoped data solutions.
• Work with software teams to deliver data capabilities.

Job description

ABOUT VALPAY

At Valpay, we're building the next generation of embedded payments. We help SaaS companies turn payments from a utility into a new line of revenue — our PayFac-as-a-Service model delivers the benefits of integrated payments while we absorb the complexity.

More than 3,000 merchants across 12 verticals in North America, Europe and Australia run on our platform. Our Growth Pods operate like small business units: each one owns the software partners it acquires, the merchants it activates, and the revenue it grows.

THE ROLE

As a Senior Data Engineer, you'll design, build and operate the data platform behind Valpay's analytics, reporting, product development and day-to-day operational decisions. Payments data is our core asset — every transaction, settlement and merchant interaction flows through systems you'll help shape.

You'll work alongside Engineering, Product, Finance, Operations and the Growth Pods to make data reliable, accessible and trusted across the company, and increasingly to make it usable by the AI-powered tools and features we're building on top of it.

This is an on-site role at our Montreal office. We build in person: our data, engineering and Growth Pod teams sit together, and the quickest way to untangle a payments data problem is at a whiteboard with the people who own the system.

WHAT YOU'LL DO

• Design, build and maintain scalable data pipelines and ELT/ETL processes across both batch and streaming workloads.
• Model and optimize our Snowflake warehouse — dimensional models, dbt transformations, and the semantic layer that analytics and product teams build on.
• Build the data foundations for payments reporting: transaction lifecycle, settlement and reconciliation, merchant performance and partner revenue.
• Own data quality, integrity, lineage and observability. You'll define what "trustworthy" means here and build the tooling that proves it.
• Improve the performance, reliability and cost efficiency of the platform as transaction volumes grow.
• Prepare and serve data for AI and LLM use cases — clean, well-documented, well-governed datasets that internal AI tools and customer-facing features can depend on.
• Partner with stakeholders across the business to turn open-ended questions into well-scoped data solutions.
• Work with software
