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.

autoscaling, HA, performance, resilience, failure modes
Strong knowledge of event-driven systems:
Kafka-based ingestion/streaming,



producers/consumers, pipelines, batching concepts
PostgreSQL / SQL proficiency (deep skills required: schema modeling, query optimization)
Kafka (hands-on experience strongly preferred)
Redis (working knowledge)
Experience working in AWS + Kubernetes environments (production familiarity expected)
Practical experience with logs, metrics, tracing to monitor and debug production systems.
Nice-to-Have

Security domain familiarity (application security / runtime protection / vulnerability management) — advantage, not mandatory
Prior work in data-intensive security platforms or similar high-scale systems
