Intelletec has partned with a vibrant and exciting new social platform that’s often been called “Minecraft for Messaging”!  You’ll be part of an ambitious team, merging the best new technologies with modern design, building an immersive new experience, that fundamentally changes the way we socialize online.

They are an agile team, backed by investors in San Francisco, CA.

This is a remote or on-site role.  As a member of their team, the Principal Engineer will be responsible for and lead all phases of their backend software development including ideation, prototyping, design, and implementation. This role is 95% hands-on development, as well as a mix of lead/architecture work and strategic planning.

Helping steer the right technology choices, standards and supporting the growth of our engineering team, the Principal Engineer will be an integral part of the company for many years to come.

This involves a solid understanding of abstract programming patterns and data structures, clear and structured thinking around code design, identifying and simplifying code complexity, and the ability to adapt to ever-changing requirements.
  • Measuring "connectedness" between two nodes in a graph.  their social network is modeled as a graph.
