• Strong understanding of scalable architectures and distributed systems trade-offs
• Experience designing robust APIs and service boundaries
• Solid experience with databases, asynchronous processing, and event-driven systems
• Strong ownership mindset across implementation, testing, rollout, monitoring, and production outcomes
• Comfortable in a fast-moving environment where engineers own quality and delivery

Preferred:

• Experience with Java or readiness to ramp up quickly
• Experience with event-driven systems such as Kafka or similar technologies
• Experience with relational databases, caching layers, and cloud infrastructure
• Experience in high-scale consumer products, live-streaming, video, AI, moderation, fintech, or communication platforms
• Experience using AI tools in engineering workflows
