• Improve scalability, reliability, observability, throughput, latency, and operational cost.
• Use AI-assisted development tools while independently reviewing their output for correctness, security, and maintainability.

Required Competence and Skills:

• Typically 10+ years of experience building and maintaining production systems, including substantial hands-on work with distributed, high-throughput data platforms.
• Typically 5+ years of professional Java experience, with a strong grasp of concurrency, memory management, and JVM performance tuning.
• Typically 3+ years of production Kafka experience, including partitioning, consumer groups, schemas, delivery guarantees, fault tolerance, and throughput tuning.
• Typically 2+ years of production Apache Flink experience, including stateful processing, windowing, checkpointing, backpressure, fault recovery, and pipeline optimization.
• Experience building and operating systems that process millions of events per minute, with direct ownership of scaling or production performance decisions.
• Strong data-modeling and database optimization skills, including work with time-series data, high-volume ingestion, analytical workloads, and PostgreSQL or another relational database.
• Experience with Protobuf, schema evolution, and compatibility in distributed systems; familiarity with gRPC and service-to-service communication.
• Hands-on experience monitoring, troubleshooting, and improving distributed production workloads, including incident resolution and resource management.
• Practical use of AI-assisted or agentic coding tools, paired with critical review of generated code before production use.
• Ability to own complex components independently, assess technical tradeoffs, and deliver maintainable solutions.

Nice to Have:

• Experience with ClickHouse or a comparable large-scale analytical database.

What if you could build an entire CRM function exactly the way you believe it should be done, rather than just manage one?

We are launching a new iGaming product in Brazil, Argentina, Colombia and Peru, and we are looking for a Head of CRM & Retention to join at the most exciting stage: when you can shape the product, make key decisions and build the system from the ground up.

This role is not about maintaining what already works. It is about building CRM & Retention according to your own vision, testing your hypotheses and seeing the direct impact of your decisions on real business results.

About the project
We are a startup within a well-established iGaming holding. We have our own platform, the resources to launch, strong in-house expertise and ambitious plans for LATAM. Above all, we keep bureaucracy to a minimum, make decisions quickly and give you real influence over what you create.

What you will own

• Building the CRM & Retention function from scratch, from strategy to first results
• Developing a CRM strategy for four LATAM markets
• Contributing to the development of CRM functionality on our proprietary platform
• Launching segmentation, triggers and automated flows: onboarding, deposits, retention, churn prevention and reactivation
• Designing bonus mechanics, loyalty programs, VIP and gamification
• Creating the promo calendar and communication strategy
• Analytics, A/B testing and driving Retention, LTV and NGR
• Building your own team as the project scales

What we are looking for

• Hands-on experience in CRM / Retention in iGaming or online casino
• Understanding of the LATAM market and practical experience with at least one of our GEOs
• Experience launching CRM from scratch or taking part in a new product launch
• Ability not only to build strategy but also to set up segments, triggers and CRM flows yourself
• Strong command of analytics, bonus economics and player behavior
• Fluent English
• Spanish or Portuguese is a strong advantage

Why this role

• Freedom to build: no need to adapt to someone else’s CRM strategy; you create your own.
• Early-stage product: you join before launch and help shape the product’s foundation.
• Direct impact: you work directly with the CEO, Product Lead and holding leadership.
• Fast decisions: fewer approvals, more action, experiments and results.
• LATAM focus: four high-potential markets from day one, with room to scale your solutions.
• Competitive compensation: discussed individually, based on your experience and expertise.
• Your team: the opportunity to build and grow the function your way.

Who we are really looking for
Not just a Head of CRM with an impressive CV, but someone who enjoys building, experimenting, taking ownership and seeing the results of their own decisions. If you have long wanted to build CRM & Retention your way instead of working within ready-made processes, this may be exactly the project for you.
