Remote | Full-Time | Amazon Growth Agency
Trivium Group is an Inc. 5000-ranked, Clutch Award-winning Amazon growth agency. We manage millions in ad spend and help brands scale profitably on the world’s most competitive marketplace. Our CSMs don’t manage accounts — they own outcomes.
We're hiring a Client Success Manager with real e-commerce and marketplace advertising experience who moves fast thinks in data, sweats the details, and treats every client like their own business.
What You’ll Actually Do
Own 40 client accounts end-to-end
You are the single point of accountability for client results and retention
Run onboarding, set strategy, deliver results, retain the account — the full lifecycle
2-hour response time during business hours, no exception
Drive results, not reports
Analyze brands' performance and profitability weekly
Diagnose problems before the client notices them
Translate numbers into clear, confident client communication
Execute with precision
Build and follow structured processes for every account (audits, keyword research, campaign architecture, optimization cycles)




Log every change. Document every decision. Nothing slips through the cracks.
Coordinate with PPC/Amazon strategists daily — you own the relationship, they own execution, and both of you own the result
Flag and escalate within hours, not days
Operate at Trivium’s pace
We don’t do slow. Scaling decisions get 2–3 weeks to play out, then we adjust. Every week has a purpose.
When something breaks, you fix it the same day or escalate by EOD
You’ll manage 1,000+ Slack messages a day with structure and discipline — unread = your to-do list
If performance is flat for 3 weeks, you’re already pitching the strategic pivot
Who This Is For
3+ years of CSM or account management experience at a digital/e-commerce agency (Amazon agency experience is a major plus)
You’ve managed 20+ client accounts simultaneously and didn’t drop the ball
You’re analytical — you think in ACOS, TACOS, sessions, conversion r
