Compensation:

We understand how to attract and retain the best talent and offer a competitive mix of salary, benefits and equity.  We also understand how important it is for you to feel challenged, to have opportunities to learn new things, to have the flexibility to balance your work and personal life and to know that your work has impact in the real world.  We have team members on four continents and we're adept at making remote workers feel like part of the team.  If you join our NYC main office be sure to bring your Nerd toys, your drones and your maker gear - we’re into that stuff, too.

Interview Process:

If you can see yourself at Selerity, send your resume and/or online profile (e.g. LinkedIn) to careers@selerityinc.com.  We’ll arrange a short introductory phone call and if it sounds like there’s a match we'll arrange for you to meet the team for a full interview.  

The interview process lasts several hours and is sometimes split across two days.  It is intended to be challenging - but the developers you meet and the topics you’ll be asked to explain (and code!) should give you a very clear sense of what it would be like to work at Selerity.  

We value different perspectives and have built a team that reflects that diversity while maintaining the highest standards of excellence.  You can rest assured that we welcome talented engineers regardless of their age, gender, sexual orientation, religion, ethnicity or national origin.
