Senior Full-Stack Engineer

About this role

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 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.
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
