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
