Web Backend Engineer

About the Role

Capsule8 is building the industry’s first container-aware, real-time threat protection platform for server infrastructure. We’ve seen first-hand how the growth of big data, cloud, and containerized microservices architectures have caused server infrastructure to change faster than traditional security approaches have been able to keep up with, resulting in reduced visibility, a lack of protection, almost non-existent forensic capabilities, and large-scale breaches having gone unnoticed for years.

As a web backend engineer you’ll help us build the systems we’re designing to help secure some of the largest and most critical production environments in the world. We’re designing experiences must be clear, intuitive, and highly functional, allowing customers to be alerted of attacks, view real-time data about their networks as well as investigate previous attacks by searching, manipulating and finding commonalities in large data sets. Our ideal new team member understands the quality and stability requirements of shipped software and can design systems that are straightforward to maintain and administer.

We are looking for candidates who are adaptable and comfortable with early stage projects, and who love a collaborative team environment. If it’s an excellent fit to your interests and skills, we encourage the opportunity to grow your responsibilities as our company grows. We are looking primarily for local candidates to join us in our Brooklyn office.
