if you are very good, nothing is a must per-se
4-7 years in Customer Success, Technical Account Management, or Solutions roles at a developer tools, infrastructure, or API-first SaaS company
proven track record owning NRR and renewals for enterprise accounts - you have grown a book, not just maintained one

strong written communication and operating cadence: crisp recaps, useful QBRs, clean escalation notes, and no loose threads
