At Space and Time, we are addressing Web3's most complex data analytics challenges at a planetary scale using decentralized, peer-to-peer technology. We are building the data foundation of Web3—a fully decentralized and community-operated data warehouse, leveraging innovative cryptography to connect tamperproof query results directly to smart contracts. This enables the seamless integration of trustless on-chain and off-chain data within a unified platform, empowering Web3 developers to rapidly create new use cases. Our team is rapidly expanding, backed by top L1 blockchains and VCs, and we have prominent enterprise partners such as Microsoft and Samsung NEXT.

A career at Space and Time is dynamic, creative, and rewarding. We value you and your ideas, offering an array of perks, including flexible workweeks, flexible vacation, attendance at exciting events, and the option to work remotely. We're headquartered in San Clemente, but we embrace remote work. Most importantly, we provide cutting-edge analytics technology to the largest dApps, DAOs, DeFi/DEXs, GameFi, NFT platforms, and enterprises. We are committed to growing a diverse and welcoming team in a safe space to be yourself and learn from the most innovative minds in blockchain and data warehousing. Help us invent the first truly decentralized data platform!

As a Senior Software Engineer on our SQL Proof Engineering team you will be joining highly skilled engineers, cryptographers, mathematicians, and tech leads responsible for developing high-performance in-database mechanisms to verify that the SQL results returned to a client are tamperproof and cryptographically guaranteed. You will be at the forefront of developing a novel Proof of SQL mechanism, akin to a specialized zero-knowledge proof/SNARK, that enables the secure loading of outsourced SQL job results into smart contracts via a decentralized oracle network, while minimizing potential attack surfaces. This role requires a strong background in applied cryptography or related mathematical fields, as well as a willingness to learn and research novel algorithms and techniques

The US salary range for this full-time position is $125,500 - $172,200. In addition to your base salary, your total compensation package includes a targeted annual bonus, RSU, and benefits.

Individual base pay depends on various factors, such as the complexity and responsibility of the role, job duties/requirements, and relevant experience and skills. Base pay ranges are reviewed and typically updated each year. Offers are made within the base pay range applicable at the time.


  • Collaborate with a highly skilled team to design and develop a Proof of SQL mechanism based on zero-knowledge proof principles and SNARKS
  • Architect and implement high-performance in-database mechanisms to ensure tamperproof and cryptographically guaranteed SQL results
  • Research and explore innovative cryptographic algorithms and techniques to enhance the security of efficiency of the Proof of SQL mechanism
  • Ensure the reliability, scalability, and efficiency of the developed mechanisms through thorough testing and optimization
  • Codifying the reliability, scalability, and efficiency of the developed mechanisms through thorough testing and optimization
  • Working with engineering leadership to define, prioritize, and ensure smooth deployments with other operational components

Skills and Qualifications:

  • Bachelor’s degree in math, computer science, computer engineering, or related technical field. Masters or PhD is a plus
  • Minimum 6+ years software engineering experience. Experience with applied cryptography is a bonus
