About Celestia Labs
Celestia is the first modular blockchain network. By decoupling consensus from execution, Celestia enables anyone to easily deploy their own blockchain, without the overhead of bootstrapping a new consensus network. Blockchains on Celestia are free from constraints, making them scalable, sovereign, and secure.
About the Team
Celestia Labs is a remote-first, globally distributed team with English as our primary language for communication. We thrive in a fast-paced startup environment and are seeking self-starters who are motivated to tackle complex challenges. While we don’t require team members to reside in specific time zones, many of us operate within European time zones (CET). Team and company events are typically scheduled between 1 PM and 6 PM CET, and team members are expected to be available for these when needed.
About You
As a Senior Engineer, you are expected to lead technical efforts, including coding, reviewing PRs, writing specifications, and facilitating technical discussions. You’ll also play a significant role in projects you’re not leading, critically evaluating how low-level technical details influence the broader goals and solutions. You bring prior experience in a similar role, demonstrating your ability to think strategically while working hands-on to solve complex problems. Our current tech stack primarily uses Golang, and while experience with Golang is preferred, we plan to incorporate more Rust in the future. Rust experience is not strictly required but is a bonus.

Responsibilities
- System Design: Design and implement complex features or entire systems, ensuring robust and scalable solutions.
- Architectural Leadership: Drive key architectural decisions, balancing trade-offs in scalability, performance, and security.
- Mentorship: Guide junior and mid-level engineers by providing constructive feedback on code, development practices, and growth opportunities.

- Cross-Functional Collaboration: Work closely with product managers, designers, and stakeholders to align on goals and priorities.
- Problem Solving: Debug and resolve complex technical challenges, taking ownership of critical issues as they arise.
Who You Are
- Highly Autonomous: You excel at working independently and have a deep understanding of system design and software architecture.
- 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.
- Networking Expertise: 3–5 years of hands-on experience with low-level networking technologies (e.g., p2p, distributed systems, blockchain). Experience exclusively with smart contracts is insufficient.
While experience in the blockchain space is preferred – having general excitement about web3 and modular blockchain technology is a must!
