Senior Software Engineer

Job Profile Summary

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.

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/Graph
  
  QL)
• 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

• Design systems that span multiple services, platforms, or product areas
• Applies appropriate data structures, algorithms, and abstractions with long-term maintainability in mind
• Establishes and enforces coding standards, error handling patterns, and best practices
• Writes clean, readable, well-structured code that is intuitive to navigate and extend
• Demonstrates strong understanding of full-stack architecture (UI, API, database, infrastructure)
• Evaluates and introduces new technologies thoughtfully, based on tradeoffs and business value
• Considers scalability, observability, fault tolerance, and performance in system design
• Understands and optimizes database performance, indexing, and data modeling
• Operates independently and anticipates problems before they occur
• Takes ownership of features from design through production and beyond
• Leads by example, promotes high engineering standards, and influences team direction through technical insight

5+ years of experience in software engineering

• Strong experience with React / Next.js or Ruby on Rails API design (REST and/or Graph
  
  QL)
• Relational databases (MySQL or similar)

• Experience with Type Script and modern frontend architecture
• Experience with Next.js SSR, ISR, and server components
• Experience with background processing (Sidekiq) and caching (Redis)
• Experience with cloud platforms (AWS), CI/CD, and containerization
• Experience with observability tooling (Datadog, Open Telemetry)
• Experience with feature flags and progressive delivery
• Experience leveraging AI-assisted / agentic development tools such as Cursor
• Familiarity with LLM evaluation workflows such as Promptfoo

Bachelor’s degree in computer science, MIS, or related field, or equivalent experience.

• Designs solutions that scale across teams and systems
• Improves engineering standards and codebase quality
• Acts as a technical leader without formal authority
• Anticipates and resolves problems before they impact delivery
• Contributes meaningfully to architecture and technical strategy
• Elevates the performance of the entire team, not just individual output

• Salary Range: $ - $ (may vary by location, experience, and other factors)
• Health, dental, vision, and disability coverage on day one
