Responsibilities

• - Design, build, and maintain backend services and RESTful APIs powering compliance and analytics products
• - Own features end to end, from technical design through deployment and monitoring
• - Build data pipelines that ingest, normalise, and index on-chain activity across multiple blockchains
• - Contribute to the architecture of new compliance capabilities — you'll be in the room where the approach gets decided, not handed the outcome
• - Model data and optimise queries against relational and NoSQL stores at scale
• - Work directly with compliance and product specialists to translate regulatory requirements into technical design
• - Improve reliability, observability, and performance of services already in production
• - Use AI-assisted development tooling as part of your normal workflow to raise output quality and speed

Requirements:

• - 3+ years building production backend systems in Java
• - Strong command of Spring Boot, JVM fundamentals, concurrency, and memory behaviour
• - Solid SQL and data modelling; practical experience diagnosing slow queries
• - Experience designing and operating web-facing services at scale — request handling, caching, rate limiting, idempotency
• - Working proficiency in both Chinese and English, spoken and written
• - Fluent, daily use of AI coding agents such as Claude Code or Codex, with a clear view of where they help and where they need supervision
• - Comfortable owning code you did not write, and reading unfamiliar codebases quickly
• - Genuine interest in the problem space — compliance products reward engineers who care why a rule exists, not only what it says

Preferred:

• - A self-starting, exploratory mindset — you investigate problems before being asked to, and you go looking for the answer rather than waiting for a ticket
• - A willingness to contribute to how the industry develops, and to speak up with constructive proposals when you see a better way — we want engineers who challenge the design, not only implement it
• - AWS in production: ECS/EKS, RDS, S3, SQS, IAM, CloudWatch
• - Blockchain or crypto exposure — node RPC integration, on-chain data indexing, wallet or transaction infrastructure
