Growth Marketing Analyst (Part Time)

Only accepting applications from people currently based in Indonesia.
Role vision
We're looking for a part-time Growth Intelligence Analyst to become the source of truth for how our brands actually grow. Experience in the Gaming or Media industry is strongly desired.
You will sit as the marketing analytics lead in a new growth team, working across a portfolio of games (mobile free-to-play and premium PC titles on Steam) alongside a small number of external client brands. Your job is to turn low-budget, mostly organic, marketing activity into a system that learns, by measuring what happens, diagnosing why, forming hypotheses, and designing the experiments that test them.
This is a deliberately focused role. We have kept the scope narrow so that roughly 16 hours a week is genuinely enough to do it well. You measure, diagnose and design experiments. Others own brand, content, creative and delivery.
We are engaging this role on a fractional or contract basis, and it is the first analytics hire in a growing team. As our portfolio grows there is real scope for the role to expand.
What makes this role unusual
Part-time by design. Roughly 16 hours a week, worked as 2 full days rather than scattered hours. We would rather have two focused days of good thinking than five fragmented ones. You will set your days with us and keep them consistent.
Smaller paid budgets. Be disciplined with spending to learn what converts across paid ads, KOL/influencer marketing, promoted community posts, and similar. We are not asking you to buy growth; we are asking you to find out what we should buy when we can.
Building analytics from ground zero. There is no existing measurement stack. You will build attribution, analytics and insight reporting from scratch, pragmatically and cheaply, with support from our technical team.
You will work across 2–3 brands at once, each with different growth goals and different definitions of success.
High-level responsibilities
Measurement and infrastructure
Map every attribution source across our brands: which channels exist, what data each one exposes, and how to collate it.
Build the systems that collate that data into something the team can read on a regular cadence, especially for the organic channels where attribution is difficult (Instagram/TikTok).
Own performance tracking and insights reporting across the portfolio.
Diagnosis and experimentation
Diagnose failures in growth activity: what went wrong, what the plausible causes are, and how we would tell which cause is real.
Turn findings into clearly written hypotheses, and design the experiments that test them.
Maintain a prioritised experiment backlog that the wider team converts into content briefs, campaigns and product changes.
Distinguish rigorously between a real signal and a coincidence, and say when the evidence is not yet there.
Paid acquisition as a learning instrument
Plan, run and optimise small-budget conversion campaigns across Meta, Google, TikTok and app store channels.
Identify which creatives, audiences and messages produce the highest conversion rates and lowest cost per acquisition, for later scaling when budget arrives.
Use paid delivery as a controlled testing environment for creative concepts that will later run organically, or vice versa.
Commercial and revenue
Contribute towards reporting on the commercial picture for our games, measuring things such as ARPDAU and payer conversion.
Connect acquisition work to actual revenue rather than vanity metrics.
Skills and experience required
1+ years in growth marketing, performance marketing, marketing analytics or a closely related role, or fewer years with demonstrably exceptional output.
Working proficiency in English, both verbal and written. Much of your output is written.
Fluency with growth tracking and management systems - analytics platforms, spreadsheets, dashboards, UTM and event taxonomy discipline. We would like you to bring your own recommendations for tools; we imagine tools like GA4, Meta, TikTok, app store consoles and Mixpanel would be helpful.
Experience growing brands organically, particularly through social media - and confidence that you can measure them.
Some experience running paid campaigns on Meta Ads, Google Ads, TikTok Ads or similar.
Desired but not essential - experience in the gaming industry, with mobile free-to-play economics, Steam, or app store optimisation.
How we will work together
You choose 2 fixed working days each week and keep them consistent, so the rest of the team knows when you are reachable.
One of those days overlaps with our weekly growth meeting, where hypotheses and experiments are agreed.
Everything else runs asynchronously and in writing. Clear written output matters more here than it would in a full-time role.
You are not expected to be available outside your working days.
Who you'll work with
You will work closely with our Growth Manager, who owns brand expression, social strategy and creator partnerships; with our designer, who produces all visual output. Positioning is decided collectively - you are the one who brings evidence to the argument.
