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

- Kafka or similar streaming platforms
