Junior Performance Marketing Specialist; Acquisition & Growth

We are looking for a Junior Performance Marketing Specialist (Paid Acquisition & Growth) to join the Growth team of a fast-growing international consumer AI technology company. This is a hands-on performance marketing opportunity focused on launching, managing and optimising paid acquisition campaigns across mainstream digital advertising platforms, including Meta, Tik Tok, Google, Instagram and Reddit.

You will be responsible for managing campaigns directly, testing new audiences and creatives, analysing performance data and implementing improvements that drive customer acquisition and commercial growth. Working closely with the CMO & Co-founder and the wider Growth team, you will gain exposure to consumer marketing at scale while developing towards independently managing larger advertising budgets.

The ideal candidate already has practical experience running paid campaigns, understands key performance metrics such as CAC, ROAS and conversion rates, and can demonstrate measurable improvements resulting from their own actions. This is an execution-focused position rather than a purely analytical or reporting role. We are looking for someone who enjoys working directly within advertising platforms, experimenting with campaign strategies and continuously improving results.

• Design and execute structured tests across audiences, targeting strategies, advertising creatives and campaign configurations.

• Evaluate test results and implement data-driven changes to improve campaign outcomes.

• Identify underperforming campaigns and take proactive steps to optimise results.

• Track individual campaign contributions and communicate actions, decisions and measurable improvements.

• Collaborate with the Growth team on acquisition strategies, creative testing and performance initiatives.

• Research emerging consumer acquisition opportunities and advertising platform developments.

• Support continuous experimentation to improve conversion, customer acquisition and marketing efficiency.

• Develop the skills and experience required to independently manage larger advertising budgets.

• Work closely with the CMO & Co-founder to support the company's consumer growth objectives.

• Hands-on professional experience in performance marketing, paid acquisition or media buying.

• Proven experience personally launching, managing and optimising paid advertising campaigns.

• Practical experience with at least one major consumer acquisition platform, such as Meta Ads, Tik Tok Ads, Google Ads, Instagram Ads or Reddit Ads.

• Strong understanding of CAC, ROAS, conversion rates and commercial campaign performance.

• Ability to demonstrate individual campaign ownership and clearly explain specific actions taken to improve results.

• Experience testing advertising creatives, audiences, targeting strategies or campaign structures.

• Ability to interpret campaign performance data and translate insights into practical optimisation decisions.

• Strong analytical thinking and a results-oriented approach.

• Comfortable working directly within advertising platforms and taking responsibility for campaign execution.

• Ability to communicate measurable campaign results and distinguish personal contributions from broader team achievements.

• Strong experimentation mindset and willingness to continuously test and refine acquisition strategies.

• Excellent organisational skills and attention to detail.

• Ability to work independently and collaborate effectively with an international remote team.
