Senior Software Engineer
About The Position
The Senior Software Engineer is responsible for designing, developing, and evolving scalable software systems across Orion’s platform. This role operates across the full stack, leveraging React/Next.js and Ruby on Rails, and is expected to make high-quality technical decisions that balance long-term maintainability, performance, and business impact. About this Opportunity: As a Senior Software Engineer, you will own the design and delivery of complex features and systems that span multiple services and product areas. You will contribute to architectural direction, improve engineering standards, and mentor other engineers while driving high-quality execution. You are expected to operate with a high degree of autonomy, anticipate challenges before they arise, and influence both technical direction and team effectiveness. In this role, you’ll get to: Design and implement scalable, maintainable systems across frontend, backend, and data layers Build and evolve applications using React, Next.js, and Ruby on Rails Design robust APIs and service boundaries (REST/GraphQL) Evaluate tradeoffs and make long-term technical decisions aligned with system evolution Ensure consistent error handling, resiliency, and system reliability Lead efforts to improve code quality, standards, and engineering practices Troubleshoot and resolve complex, cross-system issues Contribute to architecture and technical roadmap discussions Mentor engineers and raise the overall technical bar of the team Collaborate across teams to deliver solutions that span multiple systems and domains Proactively identify bottlenecks and drive improvements in performance and scalability Leverage AI-assisted development tools to improve engineering velocity while maintaining correctness and quality
