As an engineer focused on backend systems at Alchemy, you'll be working with one of the most sophisticated and high-throughput distributed systems in the blockchain world. You'll focus on architecting and building new systems as well as improving existing ones for a platform that supports millions of users globally. You'll have the autonomy to shape technical solutions, influence architectural decisions, and own services throughout their lifecycle.

WHAT YOU'LL DO

  • Design, build, and maintain backend infrastructure, APIs, and services at scale.
  • Own the architecture and implementation of distributed systems behind high-volume, low-latency APIs.
  • Solve hard scalability, latency, and performance problems in live production systems.
  • Lead system design discussions and shape the direction of our backend architecture.
  • Set the best practices for backend development—throughput, reliability, and latency.
  • Validate performance through automated testing, benchmarking, and production-driven improvements.
  • Trace production issues across services and the full stack, and ship fixes that durably improve reliability.

WHAT WE'RE LOOKING FOR

  • 5+ years of relevant industry experience.
  • BS/BA degree in Computer Science or equivalent practical experience.
  • Experience designing, building, scaling, and maintaining core backend components
  • Ability to solve complex design, scalability, latency, or performance problems in high-throughput, low-latency production systems.
  • Production experience with Java, Rust
  • Experience in cloud-native environments, particularly AWS.
  • Experience with managed Kubernetes platforms such as Amazon EKS is a plus.
  • Comfortable working across the stack, with a willingness to dive into infrastructure and platform challenges when the problem calls for it.
  • Experience building highly available and scalable distributed systems.
  • You're a self-starter who takes ownership, moves fast, and knows when to obsess over the details—and when it's time to ship.
  • Curiosity about emerging technologies and a desire to continuously learn and explore new ideas.
  • Web3 experience, a plus
  • Founded a company or built side projects, a plus
  • Experience in startups, a plus
