About The Position

This is a hands-on senior media buying role focused on live campaigns, requiring daily decisions based on performance data and accountability for profitable execution. A unique aspect of this role involves using campaign judgment to evaluate and improve AI agents that support media buying decisions. The successful candidate will turn real campaign situations into reliable ground truth, review AI agent recommendations against outcomes, and determine when the system can gain more autonomy. While an ML engineering background is not required, strong buying judgment, data fluency, curiosity about AI, and the ability to articulate campaign decisions are essential.

Requirements

• At least 5 years hands-on performance marketing, user acquisition or affiliate media buying.
• Strong practical experience with paid social, particularly Meta and TikTok.
• Strong understanding of CPA, CPL, CPI and CPS campaign economics.
• A record of making good decisions with imperfect data and explaining the reasoning clearly.
• Strong data fluency. You can read distributions, investigate anomalies and separate signal from noise.
• SQL familiarity is highly valued.
• Comfortable working directly with engineers and turning operational problems into clear rules and acceptance criteria.
• Fluent professional English.
• Based in Europe, with reliable daily working overlap with the team.
• Hands-on operating discipline. This role is for someone who wants to stay close to campaigns, not manage them through reports only.

Nice To Haves

• Affiliate networks, tracking platforms, MMPs, fraud signals or offer level optimization.
• Quality assurance, experimentation, structured evaluation or annotation processes.
• Exposure to LLM evaluation, golden sets, judge models, prompt testing or human in the loop systems.
• Experience hiring or managing media buyers, analysts or a small quality team.

Responsibilities

• Launch, monitor and own internal paid media campaigns end to end.
• Make hands-on scale, hold, optimize and stop decisions across live campaigns.
• Track spend, conversion rate, CPA, CPL, CPI, CPS, revenue and absolute profit.
• Work across performance and affiliate economics, with attention to offer, geo, audience, creative and platform differences.
• Document clear rationales for important decisions so they become useful learning signals.
• Review AI agent recommendations against real outcomes and identify errors, blind spots and unsafe actions.
• Maintain realistic evaluation scenarios, golden sets and ground truth labels.
• Work daily with the engineering team to translate business reality into measurable requirements.

Benefits

• Keep doing the media buying work you know while building a rare skill set at the intersection of performance marketing, data and AI.
• Direct access to the founder and the AI engineering team, with real influence over how the system operates.
