About Employee Navigator

Have you used a web site to sign up for your annual benefits? That's what we build. There's a good chance you've even used our software since 70,000+ companies nationwide use it.

We are a SaaS business concentrating on letting employees enroll in benefits online. Our service provides web applications for employees to enroll in benefits and administrative portals for HR, insurance brokers, and insurance companies to configure benefits. We build APIs to handle B2B transactions with our insurance carrier and payroll partners — hundreds of thousands of transmissions per day between us and the largest carriers and payroll companies.

You'll be exposed to advanced database querying on a large database (hundreds of millions of records), web applications used by millions of employees nationwide, and a large code base providing challenge and variety.

We’ve been recognized as one of The Washington Post’s Top Workplaces for eight consecutive years — and in 2025, we proudly earned our first Top Workplace award in Salt Lake City in our very first year of eligibility. Join us to help carry on our award-winning culture and be part of building something new and meaningful here!

About the Role

Our day-to-day work is in C# on .NET Core with MVC and Vue.js at the front-end. We develop software as simple as forms for data capture to Roslyn-based C# class -> ReST API generators to custom patterns handling our enrollment engine. We believe the best part of development is planning out code and discussing it with peers before writing it. Micro-ORM, dynamic SQL, or stored procedures are all used depending on the best option. We like generics and functional techniques and really like code this is easy to read.

Our mid-level engineers concentrate on handling loosely defined features and devising the proper implementation. Our senior engineers solve problems, define the features, and help coordinate implementation with other engineers. We use a Kanban process so that pace is driven by the task definition rather than an arbitrary time frame. So, we are looking for engineers who can make good decisions and find creative solutions. We work closely with our product owners -- and even executives -- to make sure features are understood and the right problems are being solved.

You'll work within a Team to handle features within a product area. The team will help with planning out features and system designs. Those will be reviewed and discussed with the Team so that the right software is written, and engineers can learn from each other. No one likes to throw out code, so you'll get the best design up front before too much coding.

Our products have assorted requirements and challenges. Some are more user-experience focused. Others require more message handling. Some are data intensive. Each Team has a variety of challenges that usually require interesting code, good planning, and good discussion.

Here's What You'll Do Day-to-day

• Plan out code and design features
• Help your teammates with reviews of their code
• Build and maintain products with real-world usage
• Rapidly iterate and roll out new code -- we ship as soon as features are complete
• Build scale into code and design
• Work with DevOps Engineers to improve tooling and pipelines
• Work with Front-End Engineers to further UI widgets
• Senior engineers will help coach coding and design techniques

Minimum Qualifications

• 8+ years of professional experience preferably in a full-stack development role
• Proven in-depth knowledge of C#
• Strong attention to detail
