About The Position

Syms Strategic Group (SSG) is seeking a talented Senior Systems Engineer with expertise in Amazon Web Services (AWS) Cloud Applications to support and modernize healthcare transaction processing and back-end data platforms. This full-time, remote position involves building cloud-native application services, APIs, integrations, and distributed workflows within an AWS-hosted ecosystem. The role requires leveraging AWS-managed services and event-driven architectures for reliable and secure healthcare data processing, transformation, and delivery. The engineer will design, build, and maintain RESTful APIs and back-end services, integrate with internal platform APIs and cloud-based data services, and develop application integrations using various AWS services. A strong emphasis is placed on writing clean, testable code, participating in peer reviews, performing unit and integration testing, and applying modern software engineering best practices within an Agile development environment. Proficiency with Git and GitHub for version control is essential. The role also requires an understanding of AI-assisted code generation, its responsible use, limitations, risks, and validation requirements, particularly in regulated healthcare environments. Strong communication and collaboration skills are necessary to work effectively with cross-functional teams, and the ability to work independently within a distributed organization is key. Attention to detail, especially regarding healthcare data accuracy, is critical.

Requirements

Experience with backend development languages such as .Net/C#, Go, Python, Java, or NodeJS
Demonstrated understanding of AWS-native application patterns and cloud integrations
8+ years of software development experience with significant back-end engineering experience
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
Strong back-end development experience using one or more modern programming languages such as .Net/C#, Go, Python, Java, and/or NodeJS
Strong understanding of AWS application integration patterns including asynchronous messaging, event-driven workflows, API integrations, and managed service interactions
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 integrations
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 or healthcare-related environments
Experience with AI-assisted development tools responsibly within professional engineering workflows
An 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
An 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)
An ability to analyze and troubleshoot complex application integration and data-processing issues
