Media Buyer

Hexcore Labs is a cybersecurity and AI company in Singapore. We run training programmes for young people, adults and companies, and our AI wing, Autobricks AI, builds AI platforms for businesses. Our creative team makes ad images and videos with AI every day, so there is always new creative to test.

We are looking for a Media Buyer to own our paid ads: where the budget goes, what we test, and what each lead and sign-up costs. You will tell the creative team what to make next, and tell us plainly what is working and what is not.

This role suits someone who has run real ad budgets with their own hands, reads the numbers without being asked, and wants to work remotely with a small team.

Responsibilities

• Plan, launch and manage paid campaigns on Meta (Facebook and Instagram), TikTok, Google and LinkedIn
• Set up audiences, budgets, bids and placements for each programme and product
• Brief the creative team on the ads to make, and test hooks, formats and offers against each other
• Track leads, sign-ups and cost per result, and move budget to what works
• Set up and maintain tracking: pixels, conversion events, UTM links and lead forms
• Keep our ad accounts within platform policies, including the rules for ads that reach parents and young people
• Send a weekly report: spend, results, what you tested and what you will change next
• Watch competitors and new ad formats, and write down what is worth trying

Requirements

• Hands-on experience running paid campaigns in Meta Ads Manager, and in TikTok Ads Manager or Google Ads
• Results you can show: campaigns you ran, what they spent and what they returned
• Comfortable with numbers and spreadsheets: CPM, CTR, CPL, CPA and ROAS mean something to you
• Experience setting up pixels, conversion events and UTM tracking
• Clear written English
• Able to work full-time on Singapore hours
• Your own laptop and a stable internet connection
• You keep people updated without being chased

Preferred qualifications

• Lead generation for education, training, events or B2B services
• LinkedIn Ads for B2B audiences
• Google Analytics 4 and Looker Studio, or similar reporting tools
• Testing AI-made creative, or using AI tools to make ad variations
• Meta or Google Ads certifications
• Advertising in Singapore or Southeast Asia

About us

Hexcore Labs is a Singapore-based cybersecurity and AI company. We train the people who want the skills, and we build the systems for the businesses that want the outcome. The same practitioners do both, which is why we teach the way we work: hands on, against real systems.

Autobricks is our agentic AI wing. It designs, builds and runs the agent workforces that go into a client’s own finance, sales, operations and creative systems, and every case we teach from is one of them.
