About the role
Your Mission
This is a company built for growth, not comfort.
When you join exmox, you’re stepping onto a global, highly competitive playing field - solving real problems in environments that push you beyond your comfort zone.
We build high-performing consumer products across multiple brands in one of the most competitive industries there is: mobile gaming. You will be part of a company that is on a path of hyper-growth, spearheading one of the largest innovations in the mobile gaming industry - a rewarded user engagement and user acquisition platform. We help mobile game publishers not only acquire new users, but also keep players engaged through rewarding experiences.
At exmox, engagement isn't an afterthought - it's one of our most important growth levers. Our reward apps (Testerup, Empfohlen, Testerheld) reach hundreds of thousands of active users, and increasing retention and customer lifetime value remains a major opportunity.
As our first Senior CRM Manager (m/f/x), you will build this function from the ground up. You'll define the strategy, select and implement the CRM platform, design lifecycle journeys, and establish a culture of experimentation and optimization. Working closely with Product, Data, Engineering, and User Acquisition, you'll transform user insights into personalized experiences that drive activation, retention, re-engagement, and long-term value.
If you're excited by building from zero, combining strategic thinking with hands-on execution, and owning a growth function with direct business impact, this role offers the autonomy, visibility, and ownership to make a difference from day one, we want to hear from you.
What You’ll Own:
Own the CRM platform end-to-end, including selection, implementation, and integration of user data across Testerup, Empfohlen, and Testerheld.
Define and execute the CRM strategy and channel roadmap across push, in-app, and email, translating business goals into measurable lifecycle initiatives.
Design, launch, and optimize lifecycle journeys across onboarding, retention, reactivation, and long-term value growth.
Build behavioral segmentation, personalization, and experimentation frameworks to deliver the right message to the right user at the right time.
Own CRM performance metrics (activation, retention, reactivation, ARPU, and LTV), using A/B testing and user insights to drive continuous improvement.
Partner closely with Product, Engineering, Data, and UA teams to ensure CRM is deeply integrated into the product experience and aligned with acquisition efforts.
Scale the CRM function from single-app engagement to cross-app lifecycle orchestration, leveraging advanced segmentation and predictive capabilities as the business grows.
What Success Looks Like:
Lifecycle journeys launch quickly: Onboarding, retention, and win-back programs are live within your first months, delivering personalized experiences across push, in-app, and email.
Retention and LTV measurably improve: Your lifecycle strategy drives meaningful gains in activation, retention, reactivation, ARPU, and LTV within your first two quarters.
CRM decisions are driven by data: Segmentation, experimentation, and performance reporting provide clear insights that guide lifecycle priorities and investment decisions.
Cross-functional teams are aligned around the user lifecycle: You partner closely with Product, Engineering, Data, and UA teams to create a seamless user journey and shared ownership of lifecycle KPIs.
You turn ambiguity into scalable systems: Through automation, testing, and process building, you establish CRM as a repeatable and scalable growth lever for the business.
What You Bring
Experienced: 5+ years of CRM experience, ideally within mobile apps, gaming, reward platforms, subscriptions, or app-first consumer businesses.
Expert: Hands-on experience implementing and managing CRM platforms, with expertise in audience segmentation, journey orchestration, personalization, and campaign automation. Experience with platforms such as Braze or OneSignal is a plus.
Data-Driven: Strong analytical mindset with experience measuring activation, retention, reactivation, ARPU, and LTV. Comfortable using data to identify opportunities, prioritize initiatives, and evaluate performance.
Experimentation-Focused: Proven track record designing and scaling lifecycle programs through A/B testing, user segmentation, and continuous optimization across push, in-app, and email channels.
Collaborative: Able to work effectively with Product, Engineering, Data, Design, and Marketing teams, translating user insights into impactful lifecycle strategies.
Work Approach: You thrive in an international, fast-paced environment and comfortable working with minimal direction in ambiguous situations.
What You Can Expect
Ambitious people, real ownership. You’ll work with driven, entrepreneurial people who care deeply about what they deliver, challenge each other openly, and own outcomes together.
We’re playing at the top, but we’re not done. Our apps rank in the top 5 of their categories. We’re determined to push further, compete harder, and earn the number one spot.
You own your own growth. Growth doesn’t happen by accident. At exmox, learning is built into the work - through responsibility, feedback, and real challenges.
Perks that help you focus on what matters. Transport subsidy, learning budget, wellness and gym, workation, bi-weekly team lunches, and more. The perks are great - but the real reason people join and stay is the challenge, the people, and the drive to win together.
Please note: this is not a remote only position, we offer you a flexible hybrid model here in Hamburg, Germany - working from home on Mondays & Fridays, coming to the office on Tuesday, Wednesday & Thursday!
