• Product Initiative Ownership: Coordinate with Product Owners and Data Analysts to refine data requirements and break down complex epics into modular stories.
• Operational Proactivity: Lead root cause analysis for production alerts and errors, specifically regarding data quality and pipeline failures.
• Mentorship: Work closely with team members to socialize standards and increase productivity through collaborative design sessions.

Requirements

• Software Engineering Expertise: 8+ years of professional backend development experience, with a mandatory mastery of the Java ecosystem.
• Polyglot Programming: 5+ years of experience with Python.
• Data & Messaging: 5+ years working with Message Bus technologies (e.g., RabbitMQ, GCP PubSub).

• Database & Modeling: 5+ years of deep experience with both Relational (SQL) and NoSQL databases, including expertise in star/snowflake schemas and data warehousing.
• AI Tooling: Proven ability to integrate Agentic LLM tools into the daily SDLC and perform "Context Engineering" to produce idiomatic, compliant code.
• Node.js Proficiency: Experience building and maintaining services within a Node.js environment.
• Frameworks & API Design: Experience with Spring Framework/Hibernate and designing GraphQL/REST APIs.
• Cloud Tools: Proficiency with Docker and containerized ecosystems such as Argo and K8s.
