Software Engineer

At Mailprotector, our Software Engineers design and build product features and improvements for our suite of email security products. We work in small, independent teams, typically on a 6-week cycle. Your day to day will be spent writing and shipping code to shape a new feature, improvement, or fix. You’ll work with our Ruby on Rails applications as well as other layers of the stack written in Python and NodeJS. Occasionally, you may even jump into the UI and work with front-end JavaScript.

You might have a computer science degree. You might not. That’s not what we’re looking for. We care about what you can do and how you do it, not about how you got here.

If you’re not in the Greenville, SC area, no problem. Our product team is distributed across the country. Remote work is embraced at Mailprotector.

This might be a good fit if you:

  • Have designed, developed, and maintained large-scale Ruby on Rails production web apps.
  • Are familiar with encryption algorithms.
  • Have experience with email protocols and systems such as SMTP, POP3, IMAP, DMARC, DKIM, Microsoft Exchange, Postfix, and Dovecot.
  • Craft solutions with a “security-first” mentality.
  • Have experience with high performance event-driven network applications.
  • Embrace a creative approach to problem-solving.
  • Have a knowledge of database systems like MySQL, Aurora, Redis, and DynamoDB.
  • Are comfortable digging in until you figure it out but know when it’s time to ask for help.
  • Enjoy the additional freedoms and responsibilities of small company culture.
  • Regularly have ideas about making things better that you can persuasively communicate.
  • Desire to improve, learn more, and make things better.

Who we are and what we do:

The Mailprotector team provides messaging security, encryption, and compliance to companies, non-profits, and governments around the world. We do this exclusively through a network of channel partners who rely on us for this mission critical application. We operate primarily from our headquarters in the historic Ivey’s building on Main Street in Greenville, SC and remote locations around the country.

Other things you should know:

  • There are multiple openings for this position and we will consider remote work for the right candidate
  • Our interview process is more involved and thorough than you think it will be. This helps us make sure we find you the right seat on the bus.
  • We’re going to pay much more attention to your cover letter than your resume.
  • We’re first and foremost a team; but that doesn’t mean this is a place to blend in. We are looking for creative, intelligent, opinionated, hard-working teammates who want their efforts and input to matter.

If you think you might be a fit for this role and for our team then we’d love to talk. Please submit your resume and bespoke cover letter. We’ll be back in touch if we think there might be a reason to talk further.
