If an agent can write the code, being the fastest coder in the room isn't much of a career plan any more. What sets engineers apart now is how much better they make the people and systems around them. This comes straight from the trenches: migrating a UK bank's app from React Native to native Android without turning the lights off on releases. There, the hard part moved from producing code to owning outcomes: getting the problem right, making the trade-offs and checking what actually shipped. Let's chat through the different paths and archetypes past senior, and how to start working that way before the title turns up. We'll look at the team as a system, and at the attack and defence strategies we used during the migration to ship faster while keeping mistakes away from customers. You'll walk away with a clearer picture of the paths beyond senior, plus a checklist to take into your next big project that keeps you and your team focused on the right outcomes.
