• Contributing to architecture and technical design with the team

What you must know already and be excited to grow further

• Proven experience in backend systems (5+ years) with exposure to large-scale, complex applications and cross-functional teams
• Fluency in Java, with a deep understanding of modern software engineering principles, including:

• Working knowledge of modern CI/CD pipelines, containerisation (Docker), and automated deployment workflows
• Strong security mindset, with practical knowledge of secure software design and common vulnerabilities (e.g., OWASP)
• Comfortable with remote team collaboration, i.e. tools and practices for asynchronous communication

Bonus points for familiarity with:

• Graph technologies: Cypher, Neo4j, knowledge graph
• Event-driven architectures, Kafka, or distributed systems
• Cloud-native development, observability, and performance tuning
• Experience working with LLMs or integrating AI/ML into production systems
• Knowledge of TypeScript or full-stack experience is welcome
