• Strong engineering fundamentals in TypeScript/Node.js, Java, Python, or similar backend/product engineering stacks
• Experience with distributed systems, APIs, async workflows, caching, observability, and production debugging
• Comfort working with AI safety patterns such as guardrails, HITL confirmation, deterministic tool boundaries, hallucination prevention, and PII-sensitive workflows
• Product mindset and ability to translate ambiguous user needs into robust, user-facing experiences
• Strong ownership mentality, with the ability to ship, measure, iterate, and support features after release
• Experience with travel, loyalty programs, personalization, fintech, or consumer data products is a strong plus
• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field, or equivalent hands-on experience
