Senior Javascript Developer
at HLA Data Systems

What we’re looking for:

A leader and teammate with superstar level development skills. We’re a small team, so we need someone who is a cultural fit, and who wants to help build our company through the next phase of growth. This would involve jumping into the domain knowledge with abandon, integrating into our existing projects, and slowly taking ownership of the codebase of our newer products. We have developers and advisors, but we need a tactical leader who can help lead us in the correct technology direction

The ideal candidate is a Node.js/JavaScript Developer with strong MSSQL history, experience with the Electron framework, and an understanding of lab work. You’ll be expected to do the following quickly: learn our database, critique our existing product codebase, deploy technology improvements, assist the deployment of new legacy product customers, ensure new products play nicely with older ones, and finally, build the product portfolio. You will also be responsible for integrating the front-end elements built by your co-workers into the application. Therefore, a basic understanding of front-end technologies is necessary as well.

  • Write reusable, testable, and efficient code

  • Document everything you build

  • Find achievable technology improvements for our company

  • Create http server programs that expose data stored in a MSSQL DB and that can broadcast and process webhook requests

  • Design and implement low-latency, high-availability, and performant applications

  • Implement security and data protection

  • Integrate data storage solutions including MSSQL (No-SQL like experience a plus)

  • Assist our team and customers with respect to SQL and Crystal Reports

  • Troubleshoot and resolve some issues raised in the customer portal

  • Some travel to client locations

  • Troubleshoot some stored procedures when needed

  • Evaluation of existing VB6 code and translation into javascript logic.
