LehiRemoteFull TimemidQuick Summary
RainFocus, one of the most innovative software companies in the heart of Utah's Silicon Slopes, is in search of an exceptional Full Stack Developer.
RainFocus is looking for a seasoned Full Stack Developer to help us build the next generation of tools that power some of the largest events in the world. You’ll be joining a fast-moving, cross-functional team focused on delivering smarter, AI-powered experiences for our internal teams and event organizers.
As a Senior Full Stack Developer, you will architect and develop enterprise-grade web applications using Java and React. You’ll also take an active role in leading by example, and helping shape the future of our technical direction.
We need collaborative, energetic team members who are capable of becoming experts in RainFocus products, industry best practices and who work well within small, focused teams.
This role sits at the heart of some of our most ambitious work: blending AI with intuitive product design to streamline complex configuration tasks and enable more personalized experiences. You’ll work closely across-functions to turn AI ideas into working solutions.
We’re looking for someone who’s collaborative, curious, and ready to build things that don’t exist yet.
Develop and maintain our core product set with a focus on usability, security, and scalability
Contribute to the design and implementation of our AI agent platform, including LLM integrations and supporting infrastructure
Collaborate closely with Product Management and UX to build thoughtful, client-facing experiences
Build and iterate on advanced prototypes that integrate LLMs, APIs, and retrieval pipelines
Implement full-stack features—from database schema and backend services to frontend components and real-time user interactions
Have a strong technical background, including 5+ years of experience working on full stack code bases and doing anything it takes to solve problems and delight users.
Experience with Claude Code, Cursor, GitHub Copilot or other AI-Assisted Engineering tools used to develop software products
Experience working with LLMs, AI agents, or RAG architectures
Experience architecting complex solutions, then projecting your vision and thought process to other developers
Experience peer reviewing code while providing feedback and improvements
Very strong written and verbal communication skills
Experience with Agile Software Development methodologies
Experience in Object-Oriented design and programming.
Experience in RDBMS (MySQL, Oracle, MSSQL, etc.) including database design and advanced SQL
Experience with front-end development using a modern JavaScript framework such as React, Angular, or Vue.
Strong interest in development platforms, Data Engineering, MLOps, AI, CI/CD, infrastructure or making products for technical teams
Able to make effective trade-offs in regards to both engineering and product requirements, while balancing short term and long term needs
Strong expertise with backend systems in service-oriented architectures
Familiarity with LangChain or other AI Agentic frameworks
Experience driving zero-to-one development of key technical capabilities
Strong problem-solver who can untangle complex systems, find the root cause, and fix issues without duct tape solutions.
Creative thinker who spots opportunities for smarter solutions and isn’t afraid to pitch bold ideas that actually move the needle.
Comfort working with vector databases (e.g., Pinecone, Weaviate, FAISS)
Experience with Struts2 MVC, Spring Framework
Experience integrating with 3rd party systems via APIs
The best candidates for this position will thrive at RainFocus not just because of their technical skills, but because of how they show up. They’re energized by solving hard problems, working with smart teammates, and figuring things out without a step-by-step manual.
They’ll need to be comfortable in a fast-paced, evolving environment where priorities shift and curiosity is rewarded.
We’re looking for someone who is:
A strong communicator who keeps others in the loop and asks great questions
Self-motivated, with a bias toward action and ownership
A collaborative team player who helps others level up
Naturally curious—driven to understand how things work and how to make them better
Comfortable with ambiguity and unafraid to make decisions when things are messy
Open to feedback, quick to learn, and always improving
