Job Description
Job DescriptionCareer Renew is recruiting for one of its clients a Senior/Staff Rust Engineer - Crypto - this is a fully remote role for US-based candidates.
We’re building the future of rollup infrastructure with a bold vision: synchronous cross chain composability.
Today, rollups are siloed. Developers are forced to choose between scalability and interoperability. We think that’s a false choice.
We are creating a modular rollup framework that allows chains to remain sovereign while achieving cross chain synchronous composability—no trusted bridges, no brittle async calls.
We’re pioneering a new architecture where:
-
App-specific L3s can interoperate as smoothly as contracts on Ethereum.
-
Shared sequencing, preconfirmations, and unified execution environments unlock atomic, cross-chain interactions.
-
Developers no longer need to choose between performance and composability.
“Imagine every rollup could synchronously compose with every other. No bridges, no delay, no fragmentation. Just fast, seamless cross-chain UX. That’s the future we’re building.”
We’re early-stage, ambitious, and backed by some of the best minds in Ethereum. Come help us build the L3 Based Appchain Stack—an open, composable future for rollups.
What You’ll Be Doing
-
Architect and implement key components of the Based Appchain Stack in Rust
-
Design low-level systems and interfaces for VMs, preconfirmations, and cross-rollup communication
-
Contribute to the design of shared sequencing and data availability integrations
-
Collaborate closely with Solidity engineers, researchers, and protocol designers
-
Engage with the Ethereum and rollup communities through events, conferences, and podcasts
About You
-
5+ years of software engineering experience, with strong focus on production grade Rust
-
Deep understanding of systems programming, concurrency, memory safety, and performance optimisation
-
Experience with Ethereum or other blockchain systems (client implementations, zk tooling, rollups, etc.)
-
Familiarity with L2 architectures like optimistic rollups, zk-rollups, modular stacks
-
Bonus: contributions to open-source Rust or crypto projects, familiarity with Cairo, zkVMs, Layer Zero, Succinct etc.
Why Join Us?
-
Be part of a team that’s reshaping Ethereum scalability and rollup design
-
Work alongside top researchers and engineers in the crypto space
-
Enjoy a fully remote setup with flexible hours and regular international team off-sites
-
Unlimited vacation policy and top-tier health, dental, and vision coverage for U.S. employees
