Job Overview We are seeking a Senior Backend Data Platform Engineer (10+ years experience) to design, build, and maintain our EMFI Data Application Platform, a high-throughput financial analytics application.

Note: This is primarily a Backend Platform Engineering (Python) role with strong data development capabilities—not a traditional heavy Data Pipeline/ETL role. Candidates will be evaluated on core backend architecture, Python, and microservices proficiency first.

- Database Optimization: Write and optimize complex SQL queries against Snowflake and PostgreSQL for reporting, aggregation, and analytical engines.
- End-to-End Ownership: Own end-to-end feature delivery—from initial requirements gathering and API contract definition to implementation,



automated testing, and cloud deployment.
- Security & Architecture: Implement microservices patterns (service discovery, distributed tracing, async processing) and ensure platform security aligned with OWASP Top 10, role-based access control (RBAC), and OAuth2/JWT.

Requirements & Technical Qualifications

- Experience: 10+ years of professional backend platform development experience delivering production-grade applications.
- Core Backend: Mastery of Python , async FastAPI patterns, microservices architecture, and Pydantic-based data validation.

- DevOps & Cloud: Hands-on with Docker/Docker Compose, Git workflows, CI/CD pipelines, and general cloud platform environments (AWS/Azure/GCP).
- Education: Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field.
- Industry Experience: Prior experience in Payments, Fintech, or Financial Services is a robust asset.
