The linked matrices below explain the requirements for all engineering specialities and levels at Teleport.
For Levels 1-3 engineers must meet the requirements for all specialities. Starting from Level 4 engineers will typically focus on one specialty.
Not all skills go to Level 6. This is determined by the focus of Teleport.
For example, security skills are more relevant, as we are a security oriented company, and we are interested in R&D Level 6 engineers, however OS/tooling is not the primary focus, so basic levels are satisfactory.
As the level advances past 4, the focus shifts from technical skills to bringing products to market, as it's more relevant to Teleport as a for-profit startup.
Skills are a mix of technical and communication abilities. Some references to security are based on the coding challenge.
