Job Description

Data Platform Engineer and Full Stack Developer
Location: Remote

About Vivid Reports

Vivid Reports builds Excel-native financial reporting and analytics software for CFOs and financial planning and analysis teams. We not only build web applications, we build metrics engines similar to a BI semantic layer that powers Excel reporting.

We believe Chief Financial Officers want Excel as their front end, but it must be powered by a governed, high-performance metrics engine behind it. We build reporting engines powered by a semantic layer that allows organizations to define KPIs once, govern them centrally, and reuse them across every Excel report the company builds, securely and at speed.
We are not building dashboards. We are building the engine behind trusted financial reporting.

You are the type of engineer that wants to be challenged and work with complex query engines, OLAP systems, semantic layers, BI tooling, financial reporting systems and ETL pipelines. All work is conducted in English. Applicants must have advanced written and verbal English communication skills.

The Role

We are hiring a Data Platform Engineer and Full Stack Developer with leadership and architecture skills that can visualize an outcome, break it to pieces, and deliver successfully.

This role is hands-on. You must understand system and data architecture and have experience designing and building business intelligence or data-driven platforms.

You enjoy building clean, high-performance backend systems as much as refining a UI to make it intuitive and visually polished.

Experience using AI-assisted development tools is highly valued. We are looking for engineers who are open-minded and practical about leveraging AI, knowing where it accelerates development, improves quality, and enhances productivity, and where sound engineering judgment still matters most.
