Job Description

Career 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

Compensation & Package

Salary + Heavy Equity shares.
