The posting

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

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.
