About Celestia Labs

Celestia is the modular blockchain powering unstoppable applications. We are pushing new paradigms for enabling a thriving ecosystem of applications which are performant, interoperable, secure and fully customizable.

About the Team

Celestia Labs is remote first and highly distributed, with English as our primary language for communication. We are looking for self-starters that are excited about working in a fast paced startup environment.

About You

You're a seasoned engineer passionate about distributed systems, cryptographic protocols, and interoperability in blockchain networks. You thrive on solving foundational technical problems and understand the balance between shipping and safeguarding critical infrastructure. You bring both Rust and Golang experience and are comfortable navigating different parts of a codebase. Knowledge of ZK systems is highly desirable. You are collaborative, proactive, and able to work independently in a remote-first environment.

Perks

• Flexible and remote work environment with multiple onsites each year
• Competitive salary and meaningful long-term compensation package
• Stipends for home office, coworking space, professional and personal growth
• 4 weeks annual vacation
• Being part of a collaborative, supportive team with opportunities for mentorship and professional growth
• 401k and healthcare coverage for US team members

Responsibilities

• Protocol Engineering: Design and implement secure and efficient bridging protocols based on zero knowledge primitives.
• Architectural Leadership: Drive key architectural decisions, balancing trade-offs in scalability, performance, and security.
• Security-First Design: Proactively identify and mitigate security vulnerabilities in cross-chain interactions.
• Mentorship & Collaboration: Provide technical guidance to junior engineers, and work closely with the broader engineering, research, and product teams.
• Lead by Example: Set high standards for code quality, testing, documentation, and effective communication.

Who You Are

• Experienced Engineer: 5+ years of backend or systems-level programming experience working in both Rust and Golang. Understanding of solidity is a bonus.
• Knowledgeable on Bridging: You’re familiar with current interoperability protocols in web3, specifically Hyperlane and are opinionated about what designs have the best properties for what users want.
• Knowledgeable on Zero Knowledge: Familiarity with designing and hands-on coding experience at implementing circuits, specifically using sp1 and risc0. You should be aware of tradeoffs in performance and efficiency between different designs and algorithms.
• Security-Conscious: Deep understanding of secure systems design, particularly around adversarial environments.
• Self-Directed: You’re highly autonomous and able to identify and own high-impact work.
• Problem-Solver: Skilled at identifying and addressing performance bottlenecks and security gaps with effective solutions.
• Technical Leader: Known for setting technical direction, mentoring team members, and driving projects to success.

While experience in the blockchain space is preferred – having general excitement about web3 and modular blockchain technology is a must!
