Offchain Labs Tech Stack

Ethereum scaling infrastructure and consensus client developer

Software Development New York, New York 51–200 employees Founded 2018 Privately Held

Offchain Labs develops Arbitrum, a Layer 2 scaling solution for Ethereum, alongside Prysm, a consensus client for the base layer. The tech stack is polyglot (TypeScript, Go, Rust, C++) and infrastructure-heavy (Kubernetes, ArgoCD, AWS/GCP/Azure), reflecting the complexity of distributed systems at scale. Hiring velocity is accelerating across engineering and finance, with a seniority skew toward senior and manager roles—typical of a scaling infrastructure company moving from research into production operations.

About Offchain Labs

Offchain Labs is a Princeton-founded blockchain infrastructure company building scaling and consensus solutions for Ethereum. The core product is Arbitrum, a Layer 2 network that processes transactions off-chain to reduce gas costs and latency on Ethereum mainnet. In 2022, the company acquired Prysmatic Labs to deepen its footprint in Ethereum's consensus layer. The team is actively shipping Arbitrum Orbit (customizable L2s), Stylus (smart contract language interop), and Arbitrum Nitro (the underlying sequencer). Current work spans core chain infrastructure, developer tooling, wallet UX, and internal scaling challenges tied to rapid growth.
