Plexus are partnered with a recently funded start up looking to improve UX by utilising account abstraction. They are looking for Rust engineers to help architect and develop the offchain architecture of the protocol.

Responsibilities

• Architect and design off-chain services in Rust, enabling feature growth and adapting to the dynamic demands of a startup environment.
• Primarily focus on developing concurrent backend systems, with occasional interaction with smart contracts written in Solidity.
• Collaborate closely with the team to launch new products and craft solutions for complex technical challenges.
• Ensure the delivery of high-quality code throughout the development lifecycle, from concept to production.
• Engage with and review code from other team members, offering constructive feedback and contributing beyond your primary responsibilities.

Relevant Experience

• 3+ years of experience in blockchain technology, particularly within the EVM ecosystem.
• 2+ years of hands-on experience writing Rust server code in a production setting (e.g., using ethers.rs and/or alloy).
• Familiarity with crypto wallets (especially smart accounts), bridging technologies, blockchain nodes, relayers, or intent-based systems, and an understanding of Layer 2 solutions and their integration with the application layer.
• Ability to balance the need for quick delivery with the creation of a stable infrastructure.
• A self-starter who can identify root causes, break down complex problems, and systematically work toward a stable and scalable solution.
• Possess a hustler mentality, with experience in founding a company, working in startups (pre-series A), or building side projects (open-source contributions are a plus).
• Capable of being a thought leader and highly collaborative, driving toward impactful outcomes.
