The company is hiring a Senior Full-Stack Engineer in Portugal who is strongly backend-leaning ( 80–85% backend) to work on high-scale backend pipelines and data-heavy systems. The ideal engineer has proven experience building production-grade ingestion and processing systems, making architecture decisions based on real data volumes, and operating reliably in Kubernetes/AWS environments. Occasional frontend work exists (small UI tasks/new pages), but the core of the job is backend systems design and implementation.
