Backend/API Engineer - Microservices Architecture

Job Description

Role Summary

The Backend/API Engineer is responsible for designing, developing and supporting secure, scalable, and high-performance APIs for the Compliance Store Data Delivery.

This role focuses on building Fast API-based data access services, integrating with enterprise authentication and transport systems, and enabling both batch and real-time data delivery.

The engineer will work closely with Data Engineers, Solution Architects, and QA teams to ensure compliant, reliable, and auditable data access.

Key Responsibilities

• Design and develop RESTful APIs using Python and Fast API for Data Access (Async, Online, and Pipeline APIs).
• Implement asynchronous batch extraction APIs with job submission, status tracking, and result retrieval.
• Develop synchronous APIs for targeted data lookups and metadata queries.
• Integrate APIs with Enterprise API Gateway and Sentinel authentication and authorization mechanisms.
• Implement API-level security, rate limiting, and access controls in compliance with HIPAA requirements.
• Integrate ECG transport for secure batch data delivery to external consumers.
• Collaborate with Data Engineers to wire APIs with Snowflake and S3-based extraction logic.
• Build and maintain Skills Registry and supporting platform services.
• Support SDK development and API client wrappers for internal developer consumption.
• Ensure comprehensive audit logging of all API requests and responses to Data Operations Metadata (DOM).
• Handle error management, retries, and observability for API workflows.
• Participate in design reviews, code reviews, and security reviews.
• Support SIT, UAT, and production deployment activities.

Required Skills and Experience

• 5 to 8 years of experience in backend or API development.
• Strong proficiency in Python and Fast API (or equivalent Python API frameworks).
• Experience designing and implementing RESTful APIs, including async workflows.
• Hands-on experience with authentication and authorization (OAuth, RBAC, token-based security).
• Familiarity with API Gateway integration and enterprise security patterns.
• Experience integrating backend services with data platforms such as Snowflake and S3.
• Knowledge of batch data delivery mechanisms and file-based integrations (SFTP, ECG or equivalent).
• Understanding of microservices architecture and containerized deployments.
• Strong debugging, performance tuning, and problem-solving skills.
• Experience in regulated or enterprise environments preferred

Qualifications

• Experience with healthcare or compliance-focused platforms.
• Exposure to audit logging and metadata-driven systems.
• Experience working with Snowflake Iceberg or external table integrations.
• Familiarity with CI/CD pipelines and Git-based workflows.
• Experience supporting developer tooling, SDKs, or platform enablement

Key Interfaces

• Solution Architect for API design and architecture alignment.
• Senior and Data Engineers for extraction logic and pipeline integration.
• Security and Platform Teams for authentication, authorization, and gateway integration.
• QA / Test Engineers for API validation and UAT support.
• Client and Business Stakeholders during UAT and acceptance phases.
