Job Description

The Sr. Data Services Engineer is primarily responsible for the implementation of scalable, resilient back-end data services for mission critical applications. You will be expected to implement backend services for applications used by external and internal customers. You will design the conceptual, logical, and physical data model, data flow, and implement the data stores and related APIs. You will store data using a variety of technologies including AWS DynamoDB, AWS RDS, and AWS HealthLake (FHIR). You will implement the APIs using cloud-native AWS services including AWS API Gateway, Lambda (node.js JavaScript), AWS AppSync, AWS Elastic Map Reduce. You will integrate with other AWS services such as EventBridge, Kinesis, SQS, OpenSearch, SNS, and S3. You will instrument your services using AWS CloudWatch, AWS X-Ray, and AWS CloudTrail.

You will collaborate with team leads, other senior developers, offshore development team members, architects, business owners, project management, and other internal stakeholders. You will automate deployments by working closely with DevOps engineers. Other responsibilities include bug fixes, support onboarding of new clients, and support production support operations.

Responsibilities

• Implement complex, scalable back-end data services using NodeJS implemented atop AWS Lambda functions with data stored in DynamoDB, HealthLake, RDS, S3, etc.
• Implement API abstraction/data access layer using AWS AppSync.
• Implement and integrate with other AWS Services such as Kinesis, SQS, SNS, Event Bridge, S3, Elastic Map Reduce (EMR), OpenSearch, CloudWatch, and X-Ray.
• Collaborate with DevOps engineers to deploy services on AWS using Terraform/Terraform Cloud and the standard Cotiviti CI/CD pipeline tools (Bamboo/Octopus).
• Support the technical design of RESTful APIs that use JSON payloads.
• Collaborate with software engineering teammates. Participate in technical peer reviews. Collaborate with architects to continuously evolve the technical architecture.
• Implement services that meet functional and non-functional requirements.
• Collaborate with Product owner(s) and other team members to develop software using Agile methodologies (SAFe, Scrum, Kanban). Contribute to all phases of the development lifecycle.
• Implement net-new, cloud-native services that can operate efficiently/cost-effectively/sustainably.
• Support production operations teams to quickly triage and resolve issues.
• Join client calls as needed to provide support and answer any technical questions.

• Preferred to have familiarity with the FHIR standard’s core use and concepts. Ideally have experience with AWS HealthLake or other FHIR-based clinical data repository.
• Familiar with implementation approaches for multi-tenant APIs on AWS—for example: how do you enforce access control to ensure tenant isolation? How data can/should be partitioned/segmented/indexed to balance cost, complexity, and performance?
• Have an engineering mindset—looking for ways to continuously improve speed to market by eliminating waste, improving quality, automating routine tasks, reusing code/libraries/capabilities.
• Experience implementing and integrating with restful APIs, microservices, and event-driven apps.
• Experienced implementing database DML queries for RDBMS, DML queries for NoSQL DB, ORM, SQL Workbench.
• Unit testing, End to end testing, performance test (lambda-tester, selenium or similar).
• Experience with AWS CloudWatch and X-Ray required. Familiarity with other Observability or APM metrics and monitoring tools.
• Proficient with using CI/CD, source code management, architecture design tools. Experience with Terraform/Terraform Cloud and git required.
• Strong proficiencies in data structures, algorithms, and design patterns.
