We exist to connect.

Mashwire is an integration agency based in Singapore, committed to connecting people and ideas to create meaningful relationships.

About the job:

At Mashwire, we blend strategy, creativity and data to deliver integrative marketing that drives real results. We’re looking for a sharp, data-driven Freelance Digital Media Planner & Buyer to architect, execute and optimize performance-focused digital ad campaigns across client accounts.

If you know how to turn budget into ROI and master ad managers with your eyes closed, let’s talk.

Your typical day may include:

Media Planning & Strategy

• Campaign Strategy: Design integrated paid digital media plans (paid social, programmatic, SEM, display, video) aligned with client KPIs (awareness, leads, conversions, sales).
• Audience Research: Identify target audience segments, behaviors and channel touchpoints using performance data and market insights.
• Budget Allocation: Develop detailed media flowcharts, target budget distributions and KPI projections for client pitches and campaign proposals.

Execution & Buying

• Campaign Setup: Execute end-to-end media setup across platforms including Google Ads (Search, YouTube, GDN), Meta Ads Manager, LinkedIn Campaign Manager, TikTok Ads and programmatic DSPs.
• Tagging & Tracking: Coordinate with our internal digital team or clients to verify UTM parameters, conversion pixels, Google Tag Manager (GTM) and tracking setups prior to launch.
• Negotiation: Where applicable, negotiate ad placements, rates or direct deals with local publisher networks and media vendors.

Optimization & Analytics

• A/B Testing & Optimization: Continuously monitor real-time campaign performance, running tests on creatives, ad copy, landing pages and audience targeting to boost campaign efficiency.
• Budget Management: Pacing ad spend effectively throughout campaign cycles to prevent over- or under-spend.
• Post-Campaign Reporting: Prepare concise post-campaign performance reports highlighting ROI, key metrics, observations and actionable insights for clients.

We’d love to have a chat if you have:

• 3+ years of hands-on media planning and buying experience (agency background preferred).
• Deep technical expertise in Meta Ads Manager, Google Ads, TikTok Ads, LinkedIn Ads and GA4.
• Strong grasp of the digital landscape and audience behavior.
• Analytical, detail-oriented, and comfortable managing campaign pacing independently.
• Meta/Google certifications are a big plus!

If you are a meticulous media buyer with a track record of driving real campaign performance, we’d love to connect with you!
