About The Role
Most agencies bolted AI on as a side tool and kept the same org chart. We changed the org chart.
A traditional agency gives one account manager 6 to 8 clients, then hires another AM when the book grows. We think that model is finished. We have spent 12+ months building the workflows, prompts and automations that take repetitive execution off a person's desk, and we are hiring the operator who runs 20 to 25 accounts on top of that system.
You are the strategic brain and the quality gate. AI produces the volume. You decide what is good enough to reach a client, and you are the person the client actually talks to.
If you have been quietly using Codex, Cursor or Claude to outwork the people sitting next to you, and wondering when someone would build a job around that, this is it.
Two things before you read further. Both are hard gates and both come up in the first fifteen minutes.
One. You have personally run live campaigns with real client money. Held the login, made the changes, carried the number. If you have supported someone who did that, this is not your role yet.
Two. You have actually used agentic AI, not just chat AI. There is a line between typing into ChatGPT and running a tool that goes off and does the work for you. You need to already be on the far side of it. That means you have installed and used at least one agentic tool, Claude Code, Cursor, Composer or a genuine equivalent, and produced something real with it.
You do not need to be good at it yet. You need to have started. We are not going to spend your first month teaching you how to install Claude Code.
What You'll Do
- Own a portfolio of 20 to 25 client accounts. Own means the client calls you, not someone above you.
- Run Meta Ads, Google Ads and SEO end to end for that portfolio. You are inside the accounts, not briefing somebody else who is.
- Use AI to produce the volume: ad copy, blog content, email campaigns, social posts, creative briefs. At a pace that is not reachable by hand.
- QA every single thing AI produces before a client sees it. This is the actual job. AI has no taste and no shame. You supply both.
- Turn the monthly numbers into something a business owner can act on, using AI-assisted analysis to get there faster.
- Take the client calls. Present the strategy. Handle the bad month as directly as the good one.
- Build and refine the prompts and workflows so quality holds across 25 accounts instead of 2. Every fix you make once should hold for everyone.
- Spot the upsell, because you are the one who can see what the campaign data is asking for.
- Keep your clients. Retention is the number you live and die on.
What We're Looking For
- 2 to 4 years in digital marketing, agency side preferred.
- You have personally held the login on live Meta and Google Ads accounts, and you can tell us the monthly spend and the cost per lead before and after you touched it.
- Hands-on with at least three of: Meta Ads, Google Ads, SEO, Klaviyo or similar email marketing, content marketing.
- You already use AI daily and can show what came out of it, not what you read about it.
- Hands-on time with at least one agentic AI tool. Claude Code, Cursor, Composer, or an agent you have actually built and run in n8n, Make or similar. Not a demo you watched. Something you set up yourself, pointed at a real task, and then had to fix when it went sideways. Beginner level is fine. Zero is not.
- You can explain a strategy to a business owner without hiding behind jargon, and you do not go quiet when a month goes badly.
- You can hold twenty plates without dropping one, and you know which systems keep you honest.
- Data-literate. You read a dashboard, see the trend, and say what to do about it.
- Based in Singapore. Your clients are here, and some of the time you will be sitting in front of them.
What You Don't Need
- A computer science degree.
- Any interest in building or fine-tuning AI models.
- To be a software engineer. You will not be shipping production code, and nobody is going to ask you to.
What you do need: to be exceptionally good at getting real marketing work out of AI, and to have already got your hands on the agentic tools. That is the whole bet.
Why This Role Exists
A traditional account manager spends most of the week on execution. Writing, formatting, pulling data, building decks. That is now largely machine work.
What is left is the part that was always the actual job: judgment, client trust, and knowing what to do next. So this role carries a bigger book, earns commission on a bigger book, and spends its time on strategy and clients instead of copy and paste.
We will not pretend the trade is free. Twenty-plus accounts is a serious load and it only works if you use the system instead of fighting it. You will ramp to that number over your first 90 days, not start at it. Perhaps 8 accounts in month 1, 10 in month 2, and so on and so forth.
Compensation
- Base: S$4,500 to S$5,000 a month.
- Commission on your portfolio revenue. 5% for all revenue collected and renewed by you. If you renew an entire portfolio of $50,000, that's already an additional $2,500 a month.
- Performance bonuses. Which are offered if you hit your own individual target and company targets.
- 80% remote. The other 20% is in person in Singapore, with your clients (in-person meetings, video shoots, etc).
- 14 days paid time off, monthly team bonding, annual company trips (upon hitting targets), paid retreats.
- A direct line to the founder. No middle layer, no politics, no three-week wait for a decision.

Here is the whole process, so you know what you are signing up for:
- The application form. 15 to 25 minutes. We read every one and we check what you write.
- A 15-minute AI screening interview. Link arrives the moment you submit. Voice conversation, taken whenever suits you, including 11pm on a Sunday. No scheduling back and forth. Have your campaign numbers handy, it will ask.
- A 45-minute call with Jim, the founder. No panel, no HR round.
- We agree the next step on that call, and you hear back either way within 5 working days.
Yes, an AI screen is unusual. We run AI in this business every day, so it would be strange to hire for it and not use it.
Best Marketing Agency Pte Ltd hires on ability and evidence. We do not ask about, or make decisions based on, age, race, religion, gender, marital status or family plans.
