Hi there!

At Flipflow , we’re looking for a Senior Backend Engineer to join our core engineering team and help us build and scale one of the most ambitious Retail Intelligence platforms in the market.

This is a deep technical role , for people who genuinely enjoy building software , thinking about architecture, and getting involved not only in code but also in product and business decisions .

If you’re excited about complex backend systems, massive-scale data processing, crawling infrastructure and making data flow reliably from collection to client — this role is for you.

About Flipflow & Our Mission

Flipflow is a Retail Market Intelligence & Digital Shelf Analytics SaaS platform , currently scaling internationally after strong growth in Spain and Latin America.

Since our launch in 2021, our mission has been clear:

To give brands, manufacturers and retailers a real-time, actionable and reliable cockpit and AI copilot to understand their products, competitors and markets — enabling better business decisions.

Retail is facing one of the biggest transformations in its history:

markets are global, competition is intense, and margins depend on data quality, speed and intelligence .

At Flipflow, we believe real-time competitive intelligence is no longer optional — it’s essential.

Your Challenge & Impact

At Flipflow, every new backend feature is an adventure and a project on its own — most of them genuinely fun if you like hard problems.

We crawl over a billion datapoints per week , process and normalize massive volumes of messy retail data, and turn that into structured intelligence used by global brands.

As a Senior Backend Engineer , your mission is to design, build and evolve the systems that:

• Collect and process massive volumes of raw data with our own crawling infrastructure
• Normalize, relate and enrich millions of products across markets with complex data pipelines
• Power our proprietary BI suite, analytics and AI-driven insights using LLMs and Agents
• Scale reliably as customers, use cases and data volumes grow

You will have a direct impact on product quality, system scalability, data intelligence and Flipflow’s long-term technical foundation .
