React Js Java Developer Jobs in Utah (NOW HIRING)

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.

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

We're looking for talent who:

Technical Excellence:

• Designs 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)

• System & Architectural Thinking

• 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

• Ownership & Independence

• Operates independently and anticipates problems before they occur

• Takes ownership of features from design through production and beyond

• Make decisions that optimize for long-term system health, not just short-term delivery

• Leadership & Influence

• Mentor's engineers and contributes to their growth

• Leads by example and promotes high engineering standards

• Influences team direction through technical insight and strong reasoning

• Challenges assumptions and proposes better solutions when appropriate

• Collaboration & Communication

• Communicates complex technical ideas clearly across engineering and non-technical stakeholders

• Collaborates effectively across teams and systems

• Drives alignment on solutions that have broad organizational impact

Required Experience:

5+ years of experience in software engineering

Strong experience with:

• React / Next.js or Ruby on Rails

• API design (REST and/or GraphQL)

• Relational databases (MySQL or similar)

Preferred Qualifications:

• Experience with TypeScript 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, OpenTelemetry)

• 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

Education:

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

What Success Looks Like (Senior Level):

• 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

Why Join Orion:

• Opportunity to shape architecture and engineering practices at scale

• Strong focus on developer efficiency, automation, and quality

• Adoption of modern tooling, including AI-assisted development

• Collaborative environment with high ownership and impact
