📋 Description

🎯 Requirements

• At least ten years of experience in backend, data platform, or distributed systems, including ownership across multiple services or teams. • Expertise in Python, API design, service boundaries, async and concurrent systems, SQL, and modern testing practices. • Proficiency with Databricks, PySpark, Lakehouse patterns, and medallion-style data architecture, or equivalent large-scale data pipeline experience. • Strong AWS serverless experience, including Lambda, API Gateway, S3, DynamoDB, IAM, and CloudFormation/SAM or equivalent infrastructure-as-code tooling. • Deep understanding of multi-tenant SaaS design, authentication and authorization, tenant-scoped data access, secrets management, and operational security. • Experience designing stable data contracts, CLI/API/MCP contracts, schema evolution patterns, and consumer-facing data models. • Proficiency with SQL and NoSQL databases such as PostgreSQL, DynamoDB, Redis, or MongoDB. • Strong CI/CD experience and deep knowledge of observability practices including logs, metrics, and traces. • Proven technical leadership through mentoring, architecture decisions, code reviews, trade-off communication, and engineering standards, without relying on direct authority. • Fluent in English, both verbal and written.
