Hi there!
At Flipflow, were 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 youre 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 .
