Data Engineer

Quartr is a software company serving the world of finance. Every day, leading companies and financial institutions worldwide use our products to research faster and understand deeper. For too long, markets have been obsessed with numbers. Everyone has access to the same quantitative data, while qualitative insights – the words, the signals, the nuance – have remained mostly in the shadows. We make those insights accessible, searchable, and actionable. Our products are used daily by some of the most sophisticated teams in finance and tech, including major hedge funds and Magnificent 7 companies, and over a million finance professionals have downloaded our mobile app. We're backed by some of the smartest minds in our industry and growing fast at a global scale, and we're still at the very beginning of what we expect to be a multi-decade journey.

Architect and maintain real-time sync pipelines between primary databases and secondary query stores (e.g., search, vector, graph, analytics). Own schema versioning and distribution. Packaging, publishing, and evolving database and event schemas across teams. Evaluate and integrate secondary indexing technologies as the needs of our AI-powered products change. Collaborate with product, data, and infrastructure teams to ensure data is accurate, consistent, and accessible in near real time. Who you are A deep generalist on the data infrastructure side with genuine expertise in how databases behave under real production conditions.
