Senior Account Manager - Trivium Group

Remote | Full-Time | E-Commerce Growth Agency

Trivium Group is an Inc. 5000-ranked, Clutch Award-winning e-commerce growth agency. We manage the growth of brands doing over $700 million in annual Amazon revenue, and we help them scale profitably on the world's most competitive marketplaces. Our Senior Account Managers don't manage accounts — they own outcomes.

We're hiring a Senior Account Manager to manage a portfolio of e-commerce clients. E-commerce client management experience is required; Amazon experience is a bonus, not a requirement. You'll need real performance-marketing instincts, speed, attention to detail, and the ability to treat every client like your own business.

You won't be doing it alone. You'll sit on top of a very capable team — PPC and Amazon strategists, creative, listing and data specialists, plus our internal AI ops agent (Viktor) — so your job is to own the relationship and the outcome, not to personally execute every task.

What You’ll Actually Do

Own a portfolio of 20–40 e-commerce brands 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.

Own onboarding like it decides the account — because it does

• The first 30 days determine whether a client renews. We treat onboarding as strategy, not paperwork.
• You set expectations, goals and the measurement plan before anyone touches a campaign.

Drive results, not reports

• Analyze brand 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, research, campaign architecture, optimization cycles)
• Log every change. Document every decision. Nothing slips through the cracks.
• Coordinate with your 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 — no exceptions. If it can't be fixed the same day, it's escalated by EOD with a plan.
• This is a high-volume Slack environment. You will need a real triage system — unread is 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 client-facing Client/Customer Success or Account Management experience at a digital, e-commerce or performance-marketing agency — or at a platform serving external paying clients. Managing e-commerce clients is required. Amazon agency experience is a bonus, not a requirement. Internal, single-brand account management does not count.
• You’ve personally owned 20+ client accounts at the same time and didn’t drop the ball.
• Hands-on experience running or managing growth for e-commerce brands selling physical products — Shopify, Meta Ads, Google Ads, TikTok Ads or Amazon.
• You're analytical: you think in efficiency and margin — ROAS, CPA, conversion rate, contribution profit — whichever platform you learned it on.
• You’re fast — you hate bottlenecks, you move things forward.
• You’re detailed — your reports don’t have typos, your data is always current, your processes are documented.
• You communicate with clarity and confidence — clients trust you because you know what you’re talking about.
• You take ownership — you don’t say “that’s not my job”.
• Fluent English (written and spoken — advanced level required).

Who This Is NOT For

• You prefer a predictable, low-pressure environment.
• You need to be told what to do every day.
• You think “good enough” is good enough.
• You avoid difficult conversations with clients.
• You’re not comfortable making decisions with imperfect data.
• Your e-commerce experience is logistics, fulfillment or operations rather than marketing and advertising.
• You've only managed one brand in-house, or a small number of enterprise accounts — we need an external, multi-client book.

Compensation & Benefits

• $4,000–$7,000/month (based on experience)
• 100% Remote
• 25 PTO days + 9 paid holidays
• Professional development + direct mentorship from leadership
• Join an 80+ person agency ranked Inc. 5000 #170, managing brands generating over $700 million in Amazon revenue

The Tools You’ll Use

Slack, Amazon Seller Central, Amazon Advertising Console, Helium 10, Jungle Scout, DataDive, My Real Profit, Adlabs, ClickUp, and Viktor (our proprietary AI ops agent).

How to Stand Out

In your interview, tell us about a time you saved a client who was about to churn. What did you see? What did you do? What happened? We want specifics, not buzzwords.
