Senior Software Engineer, Ruby on Rails

We’re looking for a Senior Software Engineer to join our insurance technology team! This is a hands-on leadership-by-example role for an engineer who cares about building software that makes a real difference. You’ll lead the build and enhancements for the invoicing capabilities of an insurance platform that supports enrollment, commissions, and billing across insurance products. You'll architect systems that simplify benefits access while aggressively modernizing how our team builds software.

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 and AWS, while helping the team identify 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
• Stay current with emerging technologies and industry trends, recommend improvements, and help ensure solutions remain secure, scalable, maintainable, and aligned with regulatory requirements

Operating at the intersection of financial services and technology, Principal builds financial tools that help our customers live better lives. We take pride in being a purpose-led firm, motivated by our mission to make financial security accessible to all. Our mission, integrity, and customer focus have made us a trusted leader for more than 140 years.

As Principal continues to modernize its systems, this role will offer you an exciting opportunity to build solutions that will directly impact our long-term strategy and tech stack, all while ensuring that our products are robust, scalable, and secure!

• Associate's or bachelor's degree (preference in a computer science, technology, engineering or math-related field) or equivalent experience
• 6+ years of enterprise level engineering experience, designing, developing, testing, and supporting software applications
• Experience working with AWS cloud-based technology
• Experience with AI, generative AI, or agentic AI technologies and their practical application within software products
• Experience creating solution architectures and building applications using Ruby on Rails
• Ability to break down complex problems, reduce ambiguity, and drive solutions forward
• Strong collaboration skills and experience working across product, engineering, and business teams
• Committed to continuous learning and enjoy helping other engineers grow through coaching, mentoring, and knowledge sharing
• Strong communication skills, with the ability to translate technical concepts clearly to business stakeholders and translate business objectives into actionable technical solutions

Skills That Will Help You Stand Out

• Experience with Python, automated testing, peer code reviews, and CI/CD practices
• Experience within insurance, financial services, or another regulated industry
• Passion for mentoring others and contributing to a strong engineering culture
