About The Position

Syms Strategic Group (SSG) is seeking a talented Senior Systems Engineer (Amazon Web Services (AWS) Cloud Applications) to support and modernize healthcare transaction processing and back-end data platforms. The role involves understanding how modern applications leverage AWS-managed services and event-driven architectures to process, transform, and deliver healthcare data reliably and securely. The engineer will design, build, and maintain RESTful APIs and backend services, build and integrate cloud-native application services within an AWS-hosted environment, and design and implement event-driven and asynchronous workflows. Integration with internal platform APIs, EDI processing pipelines, and cloud-based data services is also a key aspect of the role. The position requires developing application integrations leveraging various AWS services and writing clean, testable, and well-documented code within an Agile development environment, utilizing Git/GitHub for version control.

Requirements

Experience with back-end development using languages such as .Net/C#, Go, Python, Java, or NodeJS
A demonstrated understanding of AWS-native application patterns and cloud integrations
8+ years of software development experience, specifically with back-end engineering
Experience developing cloud-native applications within AWS environments
Experience designing and consuming RESTful APIs in healthcare, enterprise, or distributed-system environments
Proven experience building back-end services that process and deliver structured healthcare or EDI data
Experience working with asynchronous messaging, event-driven systems, or distributed application workflows
Hands-on experience developing applications that interact with AWS services such as SQS, SNS, Lambda, S3, API Gateway, EventBridge, DynamoDB, ECS/EKS, and CloudWatch
Experience designing cloud-native APIs and distributed application interactions
Experience building applications that consume and transform structured data formats including JSON, XML, and EDI transactions
Experience working with healthcare EDI data formats and transaction processing workflows
An understanding of distributed-system concepts such as retries and idempotency, asynchronous processing, fault tolerance, and service resiliency
Experience with unit and integration testing frameworks (JUnit, xUnit, Jest, pytest, or equivalent)
Proficiency with Git and GitHub collaborative development practices
An ability to evaluate when AI-assisted code generation is appropriate and when manual engineering judgment, validation, security review, or deeper analysis is required
An understanding of the limitations, risks, and verification requirements associated with AI-generated code and technical outputs, particularly in regulated healthcare-related environments
Experience using AI-assisted development tools responsibly within professional engineering workflows
The ability to evaluate, validate, test, and refine AI-generated code and technical outputs using sound engineering judgment
Strong communication skills with the ability to collaborate across engineering, platform, DevSecOps, and business teams
The ability to work independently and effectively within a distributed engineering organization
Strong attention to detail, especially around healthcare data accuracy and fidelity
Experience participating in peer code reviews and providing constructive technical feedback
Experience working within Agile development methodologies (Scrum, Kanban, SAFe, or similar)
The ability to analyze and troubleshoot complex application integration and data-processing issues
