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.
