Role Overview

This is a full-time remote role at Primetag. The Backend and Systems Engineer will be responsible for infrastructure, core services, data pipelines, and the observability platform on a day-to-day basis, producing production-grade code with high standards of performance and cost-efficiency, including documentation, testing, and APM metrics.

Who are we looking for?

We’re looking for a Back-End Engineer who’s ready to contribute at the execution level, with a sharp eye for design, a strong grasp of complex systems, and a proven track record of applying these skills to intensive production systems. But we’re also looking for a well-rounded team member, curious and proactive, who doesn’t take anything for granted, raises concerns constructively, and collaborates effectively with peers.

Responsibilities

• Design, implement, and maintain backend services and APIs (primarily Python/FastAPI and microservices);

• Maintain and evolve core microservices, databases, and supporting platform components;

• Build, maintain, and improve data ingestion and crawling pipelines;

• Help keep the platform scalable, reliable, and maintainable as load and complexity grow;

• Contribute to shared platform building blocks, including infrastructure components, internal libraries, and engineering guidelines;

• Continuously improve existing systems through refactoring, technical debt reduction, and improved observability;

• Debug production issues and contribute to incident resolution when required.

Requirements

• 3+ years of experience in Software Engineering, with a strong focus on backend development using Python;

• Experience building with any API frameworks like Django DRF, Flask, or FastAPI, among others;

• Solid understanding of REST API design principles, software design patterns, and clean architecture concepts;

• Knowledge and interest in System Design and Software Architecture;

• Valuable additional experience:

  • Experience with any of the major cloud platforms like Azure, AWS or GCP;

  • Experience working in cloud-based, containerized environments, ideally with Kubernetes in production;

  • Experience operating or contributing to data-intensive systems (ingestion, processing, storage, or search);

  • Understanding of observability practices (metrics, logs, tracing) and experience applying them to operate and debug production systems. Familiarity with tools such as Prometheus, Grafana, or Datadog is a plus;

  • Working knowledge of relational and non-relational databases, with an understanding of performance and scalability trade-offs;

  • Comfortable with event-oriented architectures and technologies like RabbitMQ or Kafka.

• Must be a fiscal resident of Portugal (regardless of nationality)
