Description:

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 adecuado 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.

Requirements:

Requirements:

- TypeScript + Node.js (production experience)
- NestJS (strong preference, used as the main backend framework)
- Strong experience designing backend systems at high scale:
- 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
