We’re the team clients hire to win, not to maintain.
GTMLab is a paid growth and strategy firm built on a contrarian bet: that data and AI, wired into every part of a marketing system, beat the legacy agency model on every axis that matters.
And we call it a Lab for a reason: winning in growth is fundamentally a question of how well you experiment. We run experiments every day, against real budgets, with real consequences. That’s the energy you’re walking into.
Why us
- We build the best. The whole team runs on a pro-athlete mentality. “Good enough” doesn’t cut it here. We train, we ship, we review, and we ship again, every day. If you genuinely enjoy solving hard problems alongside a sharp, multidisciplinary team, you’ll feel at home fast.
- You’ll learn the whole funnel, not just the ad account. Here, performance marketers work alongside strategists, creatives, funnel builders, data engineers and our own AI agents. You’ll see how a lead moves from the ad to the landing page, into WhatsApp and the CRM, and all the way to closed revenue, and you’ll learn to optimise every step of it.
- Your portfolio goes global. We run growth for clients across 6 countries, so every account is a new category, a new kind of buyer, a new problem worth solving. You won’t get bored.
- The off-sites and client meetings actually matter. Recent ones have taken us through Bali, Bangkok, Kuala Lumpur, and Singapore. You’ll be in the room where it happens, not dialing in.
The role
You’re not here to “run ads.” You’re here to bring in customers who pay.
As a Performance Marketing Manager at GTMLab, you’ll own paid acquisition for a portfolio of client accounts, turning media buying, creative and data into a steady flow of qualified leads, bookings and revenue.
Most agencies judge their ads on clicks and cost per lead. We don’t. A cheap lead that never replies is worth nothing; a pricier lead that books a consultation is worth a lot. So the job is to look past the ad platform’s report and ask the real questions: which campaigns bring buyers who actually close? Where in the funnel are we losing them: the page, the WhatsApp reply, the follow‑up? What should we test next, and where should the budget go?
You’ll work closely with strategists, creatives and our data team to find what moves the numbers, then scale the winners and cut the rest fast.
What you’ll own
- Plan, run and optimise paid campaigns across Google, Meta, TikTok and LinkedIn for lead generation clients, judged on qualified leads, bookings and closed revenue, not clicks.
- Manage budgets day to day: pacing, bids, audiences and budget shifts toward the campaigns that bring paying customers.
- Run a disciplined testing routine: one change, one question, called on enough results. Every test, won or lost, goes into the task log with what we learned.
- Work with the creative team to brief new hooks and angles, spot creative fatigue early, and keep winning ads fresh.
- Partner with our data team to keep tracking healthy so every lead is traced back to the ad that brought it.
- Look beyond the ad account. Flag leaks you see in landing pages, WhatsApp reply speed, lead quality or the offer, and work with the right team to fix them.
- Prepare clear reports and join monthly client reviews, explaining what moved, why, and what we’ll do next.
- Mentor junior specialists on your accounts as the team grows.
You’ll fit if
- You have 5+ years of hands‑on experience in performance marketing, ideally running lead generation campaigns.
- You’re strong in Google Ads and Meta Ads, and comfortable with TikTok and LinkedIn.
- You think beyond cost per lead. Cost per qualified lead, lead‑to‑sale rate, CAC, ROAS on closed revenue and LTV/CAC are numbers you reason with, not just acronyms you recognise.
- You understand that creative is where performance is won or lost now, and you can tell which ad is carrying an account and which is quietly dragging it.
- You understand tracking and attribution well enough to notice when something breaks, and to know why it matters.
- You’re organised and accountable. Fast doesn’t mean sloppy, and pressure doesn’t drop your standard.
- Fluent in English, written and spoken. You’ll use it every day with clients and stakeholders.
- Based in Jakarta and good with fully in‑person work from our office in Menteng.
Ready?
If your first question is “which of these leads actually became customers?” and not “how many clicks did we get?”, this is for you.
