Senior Software Developer

The Senior Software Developer will be focused on our flagship product, Hashtag Executive, a reporting and revenue management platform for creative professionals. You will be joining a team of three other developers to extend the core features of our existing platform to meet the needs of our publisher clients. The software works and we are currently in a closed beta. You will be helping us reach the public release and beyond. Development is primarily in PHP using Laravel 5, but we expect you to be comfortable working across the stack, whether that means tweaking CSS, tuning MySQL, or configuring a server.

Hashtag Labs sits at the center of the complex ecosystem known as ad tech. We are building a data aggregation platform, and this position is great for someone who enjoys working with numbers. If you love the free and open internet, and you’re interested in helping publishers make money, then this position is for you.


  • Modern PHP (OOP/Patterns)
  • Modern Javascript (ideally React)
  • Strong MySQL skills
  • Experience with Laravel 5.x
  • Experience with AWS (especially EC2, SQS, S3)
  • Able to collaborate well and contribute to a team

Knowledge of ad tech is a definite plus.

Hashtag Labs is a profitable company that is four years old. We are an entrepreneurial organization that focuses on making digital advertising simple and profitable for our publisher clients. We are proud to own the company and have not taken any outside investment.

We will consider Full-time (W2) and Independent Contractor (1099) candidates for this position.

Remote work is possible. Our offices are located in lower Manhattan, so if you want to come into the office, that’s great too.
