An Average Day for a Principal Engineer

• 10:00-10:15 Quick team stand-up, one of your team members seem to be working on a problem you worked on before, and offer to pair with them after the stand-up to support
• 10:30-14:00 Pairing with one of your team members to work on a complex scalability issue together and grabbing a quick bite to re-fuel those pesky braincells in-between coding sessions!
• 14:00-15:00 Doing a design session with the Product Manager and UX designer for a large upcoming feature that the team should pick up next week. You ask a lot of questions to drill down to the problem we are trying to solve, and suggest some easier solutions that require less effort for the team.
• 15:00-16:00 The design session triggered some thoughts about other areas of the system that will be affected. You’re doing a quick dive in the affected areas of the code and find some technical debt that might affect the system’s scalability or reliability. You create a brief Jira ticket and tag the Product Manager to help get it prioritised and to ensure it is not forgotten. You also ping the ticket to one of the other domains' tech leads, as you recall them mentioning a similar problem existing in another domain team.
• 16:00-16:30 Quick catch-up with the Engineering Manager on the teams delivery reliability and how you can help keep Work in Progress (WIP) and Pull Request (PR) review time to a minimum
• 16:30-18:00 Talking about PR’s, there are actually still a few open. You take the last part of the day to review your teams PRs. There are some great solutions offered, but one of the junior engineers introduced some code that is difficult to maintain and is lacking unit tests. You jump on a quick call with them to explain the issues and why it matters.
