Your first 90 days

• Weeks 1-2: your local setup is running, your first pull requests are merged, and you work through a release alongside the Lead Engineer
• Weeks 3-6: you run a release with the Lead Engineer reviewing, and you own a feature end-to-end
• Weeks 7-12: you're running merges, deploys and production support on your own

How will we know you're right

Have a quick answer to these:

• "How do you keep a release branch and a development branch in sync when fixes land on both?"
• "A deploy fails its health checks halfway through the rollout. What do you check first?"
• "A very large AI-written pull request lands on Friday afternoon. How do you review it?"
• "How do you change a busy database table without any downtime?"
