This role blends deep backend technical expertise with architectural leadership. You will contribute to the long‑term technical vision for fraud prevention, identity verification and responsible gaming enforcement ensuring our systems are secure, reliable and adaptive to evolving threats and regulations. You’ll collaborate closely with Risk, Compliance and Product partners to build a platform that balances safety, user trust and operational efficiency.

This is a fully remote role with offices located in Dublin.

Responsibilities

• Own and evolve the backend architecture that powers fraud detection and responsible gaming features.
• Design and implement distributed systems in Java and Spring Boot, building scalable services and APIs for real‑time risk evaluation, transaction monitoring and behavioural analysis.
• Collaborate with Data Science, Risk and Compliance teams to integrate fraud prevention models, transaction scoring engines and responsible gaming rulesets into core backend flows.
• Architect event‑driven systems leveraging technologies like Kafka to capture and analyse transactional and behavioural signals in real time.
• Lead large‑scale technical initiatives such as modernization of fraud detection services, identity platform evolution or real‑time customer protection pipelines.
• Establish backend and API best practices, emphasizing security, observability, reliability and compliance.
• Mentor and develop engineers, fostering a culture of technical excellence, accountability and continuous learning.
• Partner with cross‑functional teams including frontend, mobile, product and analytics to ensure seamless and secure end‑to‑end user experiences.
• Champion responsible gaming and anti‑fraud principles, helping define system patterns that promote fairness and regulatory alignment.
• Lead architectural reviews, incident post‑mortems and design sessions ensuring consistent improvement and knowledge sharing.
• Stay ahead of emerging fraud, identity and responsible gaming technologies and advocate for pragmatic adoption that strengthens our platform.
• Be open to occasional travel to Fanatics offices or industry events for planning, collaboration and team development.

Required Qualifications

• 3+ years of professional software engineering experience, with deep expertise in Java and Spring Boot.
• Proven ability to design and evolve secure, high‑scale, low‑latency distributed systems.
• Strong understanding of authentication, authorisation, payment systems or fraud prevention patterns.
• Experience designing APIs and backend systems that integrate with risk, compliance or regulatory services.
• Skilled at balancing performance, scalability and compliance in high‑traffic systems.
• Demonstrated success driving technical alignment and architectural strategy across multiple teams.
• Strong communicator who can clearly articulate complex technical solutions to engineering, product and leadership audiences.
• Passion for customer protection, data integrity and operational excellence.
• Comfortable operating in a fast‑paced, highly regulated environment with evolving priorities.

Preferred Qualifications

• Experience with AWS, Kubernetes and observability tooling (Datadog, Grafana, CloudWatch).
• Familiarity with event‑driven architectures, message streaming systems (Kafka) and real‑time data pipelines.
• Exposure to machine learning integration for fraud detection or responsible gaming scoring.
• Experience building or modernising identity, payments or compliance platforms.
