Senior Rust Engineer

Senior Rust Engineer - On-Chain Security Infrastructure

Location: Remote - Europe

Compensation: $165K - $200K

We are building a Credible Layer—a step-level improvement for on-chain security designed to safeguard the crypto industry and restore credibility after billions were lost to hacks. We are creating an on-chain protocol and off-chain infrastructure that enables protocols to enforce security rules for every transaction. Backed by world-class investors, we are seeking a Senior Rust Engineer to work on bleeding-edge infrastructure at the heart of our mission.

You will play a crucial role in shipping cutting-edge features that extend the EVM (Ethereum Virtual Machine) to enable security rules to be checked after every state transition. This is a high-impact, deeply technical role requiring expertise in performance optimization and low-level systems programming within a collaborative, fast-iteration environment.

Key Responsibilities:

• Feature Ownership: Design, drive, and own complex features throughout the whole lifecycle with a strong focus on performance and benchmarking.
• EVM Extension: Focus particularly on extending the EVM with security-focused precompiles or improving its performance with parallel processing optimizations.
• Engineering Excellence: Drive fast iteration cycles, maintain robust testing practices, and consistently raise the bar for others with high-impact, well-documented contributions.
• Collaboration: Collaborate effectively across teams, context-switching efficiently between delivering features, bug fixing, and reviewing work.
• Roadmap Contribution: Share innovative ideas to contribute actively to the team roadmap and overall product direction.

Requirements

• Core Expertise: Proven track record of shipping and maintaining complex and performant Rust code to production.
• Language Depth: A deep understanding of the Rust language and ecosystem.
• EVM Knowledge: Deep understanding of the Ethereum ecosystem, particularly the EVM and the Execution layer.
• Systems Programming: Strong background in low-level system programming and relevant optimizations, such as parallel computing architectures, profiling, and memory management.
• Mindset: Strong sense of ownership, a passion to improve existing systems, and the ability to work autonomously and solve problems independently.
• Communication: A collaborative and self-driven individual with excellent communication skills.

Preferred Experience (Nice-to-Haves):

• Experience in MEV infrastructure (e.g., Block Builders), HFT systems, Real-time data processing, or Ethereum client development (preferably Reth/Revm).
• Knowledge of Blockchain architectures (Ethereum Rollups, Mainnet) and their components (consensus, networking, etc.).
• Familiarity with SRE practices, observability tools, database optimizations, lock-free algorithms, and concurrent data structures.

Benefits

• Impact: Deeply impactful work for the entire industry, solving one of the most challenging topics in Web3 (proactive hack prevention).
• Ownership: Be part of the founding team, serving as the owner of your projects and building them from the ground up.
• Flexibility: Remote-first work environment, with a hub available in NYC.
• Time Off: Flexible PTO.
• Equipment & Events: Provided with a New MacBook and coverage for major industry conferences and events.
• Culture: Join a team that cares deeply about the space and embraces a fun, passionate work environment.
