Here, you will find a culture guided by inclusion, talented peers, comprehensive benefits and career development opportunities. Come make an impact on the communities we serve as you help us advance health optimization on a global scale. Join us to start Caring. Connecting. Growing together.

We are looking for an experienced SG28 to join our engineering organization and help build and modernize large-scale, enterprise applications.

This is a hands-on technical leadership role for someone who enjoys solving complex engineering problems while influencing architecture, engineering standards, cloud adoption, application reliability, and the technical direction of the team.

The ideal candidate combines strong Java and full-stack engineering fundamentals with experience building applications on AWS, designing APIs and distributed systems, operating production platforms, and using modern AI-assisted engineering practices.

You will work closely with product, architecture, engineering, business, and platform teams to take solutions from requirements and technical design through implementation, production deployment, and ongoing operational ownership.

Primary Responsibilities:

• Hands-on Engineering & Technical Leadership
  • Design, develop, test, and deliver enterprise-scale applications using Java, Spring Boot, APIs, microservices, and modern web technologies
  • Remain actively involved in engineering, including solution design, coding, code reviews, troubleshooting, and technical problem solving
  • Provide technical direction for complex features and engineering initiatives
  • Review designs and pull requests and help establish strong engineering standards across the team
  • Mentor engineers and help improve the overall technical capability of the engineering organization
  • Break complex technical challenges into practical, incremental solutions
• Design and build scalable, resilient, and secure applications on AWS
• Support modernization of applications from legacy environments to modern cloud-native architectures
• Apply appropriate cloud architecture patterns for scalability, resiliency, security, observability, and cost effectiveness
• Partner with infrastructure, networking, security, and platform engineering teams to resolve complex production and cloud issues
• Contribute to architecture decisions involving APIs, microservices, databases, messaging, caching, networking, and application deployment
• Application Reliability & Operational Excellence
  • Own applications through the complete software lifecycle, including production
  • Drive improvements in availability, performance, scalability, observability, and operational readiness
  • Participate in troubleshooting and root-cause analysis for complex production incidents
  • Use logs, metrics, traces, dashboards, and application telemetry to identify and resolve system issues
  • Identify recurring operational problems and drive engineering solutions that prevent repeat incidents
  • Incorporate reliability and production-readiness considerations into solution design rather than treating them as post-production activities
• AI-Enabled Engineering
  • Apply Generative AI and AI-assisted development tools to improve engineering productivity and software delivery
  • Explore practical use cases involving LLMs, Retrieval-Augmented Generation (RAG), enterprise knowledge retrieval, and AI assistants
  • Use tools such as GitHub Copilot and related AI engineering capabilities responsibly throughout the software development lifecycle
  • Help teams adopt AI-enabled development practices while maintaining engineering quality, security, and appropriate governance
• Architecture & Engineering Quality
  • Translate business requirements into scalable technical designs
  • Evaluate solution alternatives and communicate architectural trade-offs clearly
  • Develop reusable engineering patterns and reduce unnecessary technical complexity
  • Champion secure coding practices, automated testing, code quality, and engineering standards
