Python data platform engineer

Senior Python Data Platform Engineer to join our integration engineering team powering our core Data Platform Service. Built on a tightly integrated modern stack consisting of AWS, Confluent Cloud, Kubernetes, and Snowflake, this platform serves as an operational data mesh. It delivers source- and consumer-aligned data products exposed via event streams, serverless REST APIs, and high-performance data stores to drive mission-critical, real-time transactional and operational workloads. In addition to hands-on software development, you will serve as a technical pillar within the team—guiding technical standards, conducting rigorous code reviews, and acting as the primary backup to the lead developer.

• Build, optimize, and maintain Python-based containerized event-processing services deployed as headless AWS ECS Fargate tasks consuming from Kafka.
• Design, implement, and maintain scalable AWS Lambda functions exposing clean REST APIs for data product consumption, implementing robust API versioning and alias routing strategies.
• Connect high-throughput event pipelines using Confluent Cloud (Kafka) to feed operational data stores and analytical engines like Snowflake.
• Partner closely with the lead developer as their primary backup, contributing to architectural decisions and enforcing high standards through active code reviews.
• Maintain reliable deployment pipelines using advanced Git workflows, automated testing, and continuous integration practices.

• 5+ years of relevant work experience
• Mastery of advanced object-oriented Python, classes, and metaprogramming.
• Deep experience with data classes, type validation, and algorithmic design patterns.
• Proven track record building REST APIs, AWS Lambda handlers, transformation services, and automation scripts.
• Strong expertise with Git workflows, merge requests, conventional commits, and CI/CD pipelines.
• Solid practical experience with database operations (both relational and non-relational), database design, and advanced SQL.
• Extensive experience handling semi-structured data structures (JSON, XML).
• English C1
• Mandatory to be located in Portugal
• Будет плюсом: Working experience with core AWS services, including EC2, S3, RDS, VPC, IAM, and CloudWatch; Familiarity with Confluent Cloud / Apache Kafka concepts (topics, partition handling, producer/consumer design); Hands-on exposure to AWS ECS / Fargate container orchestration, AWS Lambda runtime configuration, or Kubernetes; Familiarity with Snowflake or distributed data mesh principles is a plus

• Hybrid – 1 day per week on-site in Lisbon.
