You'll lead the development and enhancement of capabilities for an insurance platform that supports enrollment and onboarding across insurance products. You'll help architect systems that simplify access to benefits while modernizing how our team builds software. You'll initially support a platform built using Ruby on Rails and AWS, with the expectation that our technologies will continue to evolve.We're looking for someone who brings strong software engineering fundamentals and is comfortable learning, adapting, and working with new technologies as the needs of the platform and business change. You'll have the opportunity to: * Own the design and development of scalable software solutions, contributing across the full development lifecycle from requirements and solution architecture through testing and production * Build and enhance applications using Ruby on Rails or similar modern application frameworks and AWS, while remaining adaptable as our technology stack evolves and identifying meaningful opportunities to incorporate AI and agentic AI capabilities. * Partner closely with product managers, designers, engineers, and other stakeholders to refine requirements, evaluate technical and product trade-offs, and deliver prioritized roadmap initiatives * Provide senior level technical leadership by establishing development approaches, influencing architectural decisions, reviewing code, mentoring engineers, and helping the team solve complex technical problems * Own software quality through automated testing, peer code reviews, performance planning, secure coding practices, and reliable CI/CD pipelines * Deliver software predictably by developing accurate estimates, communicating progress and risks, and taking accountability for moving projects from requirements through production, This role offers in-office, hybrid (blending at least three office days in a typical workweek), and remote work arrangements (only if residing more than 30 miles from Des Moines, IA, or Charlotte, NC).
