This is a remote position.

The company provides a security framework embedded at the blockchain base layer that is designed for dApp developers, and enforces verifiable, on-chain security assertions to prevent hacks and vulnerabilities. Their system provides proof of provenance mechanisms for preemptive exploit validation, and an Assertion Registry for managing and monetizing security rules. Their infrastructure provides a transparent, decentralized approach to blockchain security, allowing developers to define and enforce security protocols with resilience and ease.

They’re looking for a Senior Rust SEngineer to join their team and work on bleeding-edge infrastructure that safeguards the crypto industry. By joining the team, You will play a crucial role in shipping cutting-edge features that extend the EVM to enable security rules to be checked after every state transition, right at the heart of the company’s infrastructure, as well as contribute to core open-source crypto infrastructure and the ability to solve novel and complex problems.

MISSIONS

• Design, drive and own complex features throughout the whole lifecycle with strong focus on performance and benchmarking. Particularly in extending the EVM with security-focussed precompiles or improving its performance with parallel processing optimizations.
• Collaborate & communicate effectively across teams.
• Emphasis on fast iteration cycles driven by performance benchmarking and robust testing practices.
• Ability to context-switch between delivering features, supporting bug fixing, and reviewing work
• Share innovative ideas to contribute to the team roadmap and consistently raise the bar for others with impactful contributions.

The ideal candidate has a T-shaped skillset, a wide range of technical breadth, and deep knowledge in a specific area across the stack (EVM, performance, database, optimization, debugging). You are able to support the team with shipping robust and performant code,fast.

Requirements :

• Proven track record of shipping & maintaining complex and performant Rust code to production.
• A deep understanding of the Rust language and ecosystem. Rust being your primary language
• Deep understanding of the Ethereum ecosystem, particularly EVM and the Execution layer, and real life experience with Ethereum infrastructure
• Engineers with a strong sense of ownership, a passion to improve existing systems, and the ability to work autonomously and solve problems independently.
• A collaborative and self-driven individual with excellent communication skills and the ability to work collaboratively across teams.
• Strong background in low-level system programming and relevant optimizations, such as parallel computing architectures, profiling, and memory management

Nice to have :

• Experience in either of these: MEV infrastructure (e.g, Block Builders), HFT systems, Real-time data processing, database design, Ethereum client development (preferably Reth/Revm).
• Knowledge of Blockchain architectures (particularly Ethereum Rollups, Ethereum Mainnet) and their various components (consensus, networking, etc.).
• Familiarity with System Reliability Engineering (SRE) practices and observability tools for debugging or optimizing the systems you develop.
• Familiarity with Database optimizations, lock-free algorithms, concurrent data structures, and SIMD or other CPU-level optimizations., Maintain backend services in Rust, integrate and maintain the company’s React web presence, build metaverse infrastructure and netcode in .NET within Unity, and develop blockchain integrations for customer transactions. The role requires broad programming knowledge, Linux proficiency, rapid learning, interest in crypto and blockchain development, and the ability to complete complex projects. GCP and Kubernetes experience is advantageous, while netcode, metaverse, game development, and backend service experience are pluses.
