  • Helping ensure engineering efforts are aligned with business priorities and product goals
    • 8+ years of hands-on Java development experience
    • Strong software architecture and system design skills
    • Experience with distributed systems and messaging technologies (RabbitMQ, Kafka, or similar)
    • Strong understanding of scalability, reliability, and performance optimization
    • Solid SQL and database design experience
    • Experience using AI agents and AI-assisted development tools in the coding process (e.g. Claude Code, GitHub Copilot, ChatGPT, Gemini)
    • Ability to work independently and make strategic technical decisions
    • Experience conducting code reviews and mentoring engineers
    • Excellent communication and stakeholder management skills
    • Strong spoken and written English
Nice to Have
