Engineering competencies are used to inform conversations about career progression between an engineer and their line manager. This section of the site outlines the competencies for each level of engineer. Before reviewing competencies for your level, read how to use them here.
Junior Engineers are expected to work mostly independently on areas of the system that are reasonably straightforward, and to be supported by members of the team on areas that are more challenging. They participate fully in team events, express opinions, learn new skills, and act with the same integrity and respectfulness as expected of everyone. Read all of the Junior Engineer competencies
Mid level engineers should be proficient in the technical systems that they are working on. They should be aware and guided by the wider context of their work. They should take responsibility for their work and own their personal development. They should be working as part of a team to achieve the shared goals of the team.

Senior 1 (S1) engineers are expected to improve the performance of those around them. This could be through additional official responsibilities such as line managing or tech leading, or through unofficial means such as mentoring or regular pairing. S1 engineers should be able to tackle more complicated technical problems, and explain and justify their approaches to their team. We expect S1 engineers to pick up work outside of their delivery team and manage that work effectively against their delivery team’s priorities. S1 engineers require very little oversight beyond high level direction. Read all of the Senior Engineer 1 competencies
The Senior 2 (S2) engineer exhibits leadership and influence well beyond themselves. This influence could be through tech leading, line managing, mentoring, or leading projects outside of their day-to-day work. Senior 2 engineers are good at seeing ill-defined or difficult projects through to completion. They are great at spotting issues and helping their team navigate them. Senior 2 engineers have a deep understanding and willingness to help others for a particular technology or product. Read all of the Senior Engineer 2 competencies
