Job description

Staff Level Software Developer

US East Office (Jacksonville, FL) - Hybrid weekly schedule
We exist to transform our customers and change lives

Who We're Looking For:

RF-SMART is currently seeking a staff level software developer with web application architecture experience to work with an agile development team located in Jacksonville, FL. This integral member of our Products team will be responsible for being a technical resource for design, development and delivery of software as a service products.

May participate in activities to include, but not limited to:

  • Working with Product Owners to define and refine product requirements
  • Serve as a technical resource for other senior developers from an architectural perspective
  • Designs, modifies, develops, writes and implements software programming applications
  • Contribute in discussions regarding the direction of existing and future product offerings

What You'll Do

  • Design, build, and maintain full-stack features using C# / .NET on the backend and React on the frontend, writing production-quality code every day
  • Lead the architecture and technical design of complex, cross-functional features — from initial scoping through delivery and beyond
  • Own hard problems: you're the person the team brings their toughest bugs and most ambiguous challenges to
  • Conduct thorough, constructive code reviews that raise the quality bar and help engineers grow, not just ship
  • Mentor and coach junior and mid-level engineers through pairing, design discussions, and direct feedback — investing in people as much as the product
  • Collaborate closely with Product and Design to shape requirements, push back when needed, and ensure the right thing gets built the right way
  • Debug and diagnose complex issues across the full stack — performance bottlenecks, race conditions, memory leaks, integration failures — and drive them to resolution
  • Champion engineering best practices: testing strategies, CI/CD hygiene, observability, and documentation
  • Identify gaps in tooling, process, or technical approach and lead the effort to close them — you don't wait to be asked
  • Serve as a technical point of contact across teams, representing your domain with clarity and confidence

What You Bring

  • Expert-level proficiency in C# and .NET (6/7/8+), including async patterns, performance optimization, and API design
  • Strong hands-on experience with React, including hooks, component architecture, state management, and modern frontend tooling
  • A sharp eye for UI/UX — you care about how things look and feel, not just whether they work
  • Proven ability to debug deep, systemic issues across backend services, APIs, and frontend applications
  • Experience mentoring engineers and elevating team capability through example, feedback, and knowledge sharing
  • Comfortable leading technical discussions and driving decisions in a collaborative, consensus-building way
  • Strong written communication — your design docs and code comments are as clear as your code
  • A track record of owning large, complex features end-to-end in a fast-moving environment

Why You'll Love It Here: Working at RF-SMART means joining a culture that values growth, collaboration, and innovation. As a Staff Level Developer, you'll work alongside a passionate team dedicated to making a difference—both for our customers and our employees.
