At Space and Time, we are solving Web3’s toughest data analytics challenges at planetary scale with decentralized, peer-to-peer technology. We are building the data foundation of Web3: a fully decentralized and community-operated data warehouse, using novel cryptography to connect tamperproof query results directly to smart contracts. This enables joining trustless on-chain and off-chain data in a single platform, allowing Web3 developers to build new use cases quickly. Our team is growing fast, backed by the top L1 blockchains and VCs, as well as enterprise partners such as Microsoft and Samsung NEXT.

A career at Space and Time is lucrative, fast-paced, and very creative. We value you (and all your ideas) like family and we bring an endless supply of perks. This includes flexible workweeks + flexible vacation, add-on bonuses for hard work, we attend exciting events/conferences/parties, we’re headquartered on the beach near LA (but don’t mind you working remote), and most importantly- we provide analytics technology to the largest dApps, DAOs, DeFi/DEXs, GameFi, NFT platforms, enterprises, etc. 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. Your team will be architecting and developing a novel Proof of SQL mechanism (effectively a specialized zk-style proof/SNARK) which ensures that results of outsourced SQL jobs can be loaded into smart contracts via a decentralized oracle network, while also minimizing attack surfaces. This is an extremely math/cryptography-heavy role, and thus we expect competency (and a professional or academic background) in applied cryptography or related mathematical fields. Experience with high-performance distributed computing is a plus. We also expect willingness to learn and research novel algorithms and techniques.

The US salary range for this full-time position is $145,000 to $185,000. 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.
