About the Role
We are seeking an experienced and motivated Senior Cloud Engineer to join our team and play a pivotal role in a mission-critical project. You will be a key developer in building the next generation of our healthcare data platform to achieve compliance with new federal interoperability regulations (CMS-0057-F).

You will be responsible for designing, developing, and deploying the central security and orchestration hub of our new architecture, a Proxy FHIR Service, as well as a suite of critical, asynchronous background jobs that power our data exchange capabilities. This is a unique opportunity to work with modern cloud technologies on a project that will directly impact how patient data is shared and managed across the healthcare ecosystem.

What You'll Do
Develop the Core Proxy Service: You will build and own the central Proxy FHIR Service, a C# serverless function that acts as the secure gateway for all our interoperability APIs.
Implement Robust Security: You'll engineer the security core of the service, responsible for validating external Okta JWTs, enforcing OAuth 2.0 scope-based authorization, and managing a secure internal token exchange to protect backend systems.
Build Complex Workflows: You will design and implement intelligent routing logic to handle the multi-stage workflows required by the Prior Authorization API, differentiating between CRD, DTR, and PAS requests.
Engineer Resilient Background Jobs: You will develop a series of robust, scheduled, and event-driven background processes, including:
o A job to synchronize member consent choices (opt-in/opt-out) from Salesforce to a central repository.
o A complex, long-running job to orchestrate the Payer-to-Payer data consumption process, which includes calling external APIs, parsing FHIR bundles, and transforming data for our claims system.
o A job to establish provider-patient attribution by processing historical claims data.
Ensure Data Conformance and Quality: You'll work closely with data teams to ensure all processes align with the HL7 FHIR US Core Implementation Guide (v7.0.0) standards mandated by the project.
Collaborate and Innovate: You will work with solution architects, business analysts, and QA engineers to translate detailed functional requirements into elegant, scalable, and production-ready code.

What We're Looking For
Required Skills & Experience:
5+ years of professional software development experience in C# and the .NET Framework.
Strong, hands-on experience building solutions on major cloud platforms (Azure, AWS, or similar), particularly with serverless computing technologies (e.g., Azure Functions, AWS Lambda).
Deep understanding of RESTful API design, security principles, and standards like OAuth 2.0 and JWT.
Proven ability to design and build reliable, scalable, and maintainable backend services and asynchronous processes.
Experience reading and interpreting detailed technical specifications and functional requirements documents.

Preferred Qualifications (Bonus Points):
Experience in the healthcare technology domain, especially with interoperability standards like HL7 FHIR.
Familiarity with the Da Vinci Implementation Guides (CRD, DTR, PAS) for prior authorization is a significant plus.
Practical experience integrating applications with identity providers like Okta.
Experience working with data from Salesforce, particularly via its APIs.
Knowledge of cloud API Gateway technologies and patterns for securing and managing API traffic at scale.
Experience with cloud-native healthcare data solutions (e.g., AWS Health Lake, Azure Health Data Services).
