We are looking for a Principal Software Engineer to focus on our Joist product.

Joist, an EverCommerce solution group and member of the EverPro suite of products, is an end to end vertical software platform for small & medium-sized trades contractors. We have a simple mission: Make Contractors Heroes. Joist provides web and mobile applications for small business contractors to estimate, invoice, record, and process payments, and manage projects from anywhere. From humble beginnings, we're now helping over 1 million contractors across North America, the UK, and Australia, making us one of the largest trades platforms in the world and we have major growth planned!


You will contribute to solutions from inception to deployment, and everything in between. The solutions you and your team build must not only work for Joist today, but also support rapid iteration and innovation as we grow. Your work is going to be nothing less than redefining the home renovation industry, and your tool belt is full of a multitude of technologies, frameworks, and software design strategies. The key aspects of this role include:

Architecture You have a strong understanding of the building blocks of a robust and scalable system. You are able to dissect business problems into well designed systems. You have the experience to know what to build and the discipline to know what not to.

Server Side Technologies You are well versed in server side architectures such as monolithic or microservices. And are not only able to take advantage of modern frameworks; but also dive deep into the specifics when needed in order to build robust RESTful APIs.

Code Quality You write effective, scalable, and highly readable code. You have lots of experience in reviewing the code of your peers and know effective ways of communicating code quality standards with the broader team.

Delivery Focused Code on a laptop doesn’t solve problems. You know that a project is only done once it's delivered and validated. Residential construction is a large problem to tackle. You are driven to complete a project because you know that 5 more problems are waiting to be tackled, and you do it all without sacrificing quality.

Teamwork Many of the problems we encounter require insight from many parts of the business. Your ability to coordinate and communicate across teams is essential to our success.

Passion Hard problems are not solved overnight. It takes a special kind of attitude and hunger to disrupt an entrenched industry. Your passion is what you share with every teammate at Joist. Passion for technology, passion for change, and passion for building an industry revolutionizing product.

  • 10+ years of professional industry experience delivering scalable software solutions using Ruby on Rails

  • Experience building complex server-side systems using distributed architectures

  • Experience in working with Docker for local development and deployment

  • A proven ability to mentor and grow the engineering skills in your teammates

  • Experience in performing detailed root cause analysis up and down the software stack using a variety of debugging tools
