The posting

Our client is an innovative Layer 1 blockchain company building high-performance infrastructure for the next generation of decentralised applications. Their ecosystem spans blockchain infrastructure, decentralised finance (DeFi), cross-chain technologies, and Real-World Asset (RWA) solutions. They are looking for experienced backend engineers to build highly scalable, low-latency distributed systems that power mission-critical blockchain services.

Responsibilities

  • Design, develop, and optimise high-concurrency, highly available microservices and distributed backend systems.
  • Build distributed platforms capable of supporting millions of QPS with low latency, high throughput, and 99.99%+ availability.
  • Drive microservices architecture, including service decomposition, API design, service governance, distributed tracing, circuit breaking, and graceful degradation.
  • Perform performance tuning, capacity planning, incident troubleshooting, disaster recovery, and middleware integration/customisation.
  • Develop high-quality, scalable code while promoting engineering best practices and technical standards.

Requirements

  • Bachelor's degree in Computer Science or a related field
  • 5+ years of experience building large-scale internet or high-concurrency backend systems.
  • Strong blockchain experience with EVM, Sui, and Solana, including on-chain data querying, smart contract interaction, latest block monitoring, and historical blockchain analysis.
  • Deep understanding of microservices, distributed systems, service governance, distributed transactions, idempotency, and traffic control.
  • Proven experience designing and optimising high-concurrency, highly available systems, including rate limiting, circuit breaking, disaster recovery, degradation strategies, and multi-active deployments.
  • Strong Java expertise with JVM internals (memory model, GC, lock optimisation) and proficiency in Spring Boot and Spring Cloud.
  • Hands-on experience with Kafka/RocketMQ, Redis Cluster, MySQL (sharding/partitioning), database optimisation, and deploying and maintaining cloud-based middleware infrastructure.
  • Excellent cross-functional communication and collaboration skills with the ability to drive technical solutions from design to production.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
