Participate in on-call rotation, one week in every six, remunerated.

First month: full induction. You'll understand the company culture, the product, the codebase and your team. You'll have all the tools you need, including your AI tooling set up the way you like it, and we'll aim to have you making your first meaningful contribution to production infrastructure inside two weeks.

By 3 months: you've added your own stamp to the infrastructure. You're making real improvements to our infrastructure and security posture, working with less oversight and building trust with the team and wider stakeholders.

By 6 months: you're delivering a significant piece of work from scoping through to production, spotting problems before they bite and bringing solutions to the team. You've found at least one thing an agent should be doing for us that isn't yet, and made it happen.
