ppbAt Flipflow /b, we're looking for a bSenior Backend Engineer /b to join our core engineering team and help us build and scale one of the most ambitious Retail Intelligence platforms in the market. /ppThis is a bdeep technical role /b, for people who genuinely enjoy bbuilding software /b, thinking about architecture, and getting involved not only in code but also in bproduct and business decisions /b. /ppIf 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. /ppFlipflow is a bRetail Market Intelligence Digital Shelf Analytics SaaS platform /b, currently scaling internationally after strong growth in Spain and Latin America. /ppSince our launch in 2021, our mission has been clear: /ppTo 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. /ppRetail is facing one of the biggest transformations in its history: /ppmarkets are global, competition is intense, and margins depend on bdata quality, speed and intelligence /b. /ppAt Flipflow, we believe breal-time competitive intelligence is no longer optional /b — it’s essential. /ppAt Flipflow, every new backend feature is an badventure and a project on its own /b — most of them genuinely fun if you like hard problems. /ppWe crawl bover a billion datapoints per week /b, process and normalize massive volumes of messy retail data, and turn that into structured intelligence used by global brands. /ppAs a bSenior Backend Engineer /b, your mission is to design, build and evolve the systems that: /pulliCollect and process massive volumes of raw data with our own crawling infrastructure /liliNormalize, relate and enrich millions of products across markets with complex data pipelines /liliPower our proprietary BI suite, analytics and AI-driven insights using LLMs and Agents /liliScale reliably as customers, use cases and data volumes grow /li /ulpYou will have a bdirect impact on product quality, system scalability, data intelligence and Flipflow’s long-term technical foundation /b. /ppWhat will you do? /pulliDesign, build and maintain bcore backend services and APIs /b — PHP/Laravel as the main framework, with TypeScript, Python and Go across different services. /liliBuild and operate blarge-scale data pipelines /b — ingest data from hundreds of crawled sources, transform and normalize it, and deliver it reliably to our OLAP engine so clients see fresh, accurate data every day. /liliWork on bevent-driven and streaming systems /b — message queues, async processing, real-time data flows. You’ll ensure data moves efficiently from collection to delivery at scale. /lilibJump between codebases, languages and layers /b as needed — from Terraform to TypeScript to PHP to Go. If something is broken or needs building, you own it regardless of where it lives. /lilib12+ years of experience /b in Backend or Full-stack roles. /lilibData pipeline engineering /b — you've built systems that ingest, transform and deliver large volumes of data reliably. Not analytics or dashboards — the plumbing that makes data flow from source to client. /lilibEvent-driven architecture /b — message queues (Pub/Sub, SQS, Kafka), async job processing, streaming. You've built systems where millions of events flow through multiple stages without losing data. /lilibComfortable across the full stack /b — you don't need permission to jump into a new codebase, language or layer. If it's broken, you fix it. If it needs building, you build it. /lilibStream processing /b (Apache Flink, Kafka Streams) — building and operating real-time data flows, not just consuming them. /lilibKubernetes + IaC /b (Terraform/OpenTofu) — you can own the deployment, not just the code. Helm, ArgoCD, GCP/AWS. /lilibOLAP / time-series databases /b — ingestion, partitioning, performance tuning for analytical workloads. /lilibEnglish proficiency /b: fluent communication in professional environments, with at least a B2 level. /lilibCompensation: /b Competitive senior-level salary aligned with experience and impact /lilibReal ownership: /b You will shape core systems, not just implement tickets /lilibHard technical problems: /b Massive data, AI in production and complex distributed systems /lilibFlipflow culture: /b High standards, autonomy, trust and frequent feedback /lilibLocation: /b Offices in La Marina, Valencia, with wonderful views of the sea /li /ulpAt Flipflow, senior engineers are bbuilders and decision-makers /b, not just executors. /ppWe offer: /pulliOwnership over meaningful technical problems /liliSpace to design, refactor and improve core systems /liliReal-world AI and data challenges /liliA strong, ambitious team building something that genuinely matters /liliIf you want to bbuild the systems that move data at scale /b, and be part of a company aiming to define a new standard in Retail Intelligence, we'd love to meet you. /li /ul /p #J-18808-Ljbffr
