At Space and Time, we are solving Web3’s toughest data analytics challenges at planetary scale with decentralized, peer-to-peer technology. Apps built on top of Space and Time become blockchain interoperable, crunching SQL + machine learning for enterprises and any decentralized applications that need verifiable tamperproofing, blockchain-security, or enterprise scale. We turn any major blockchain into a next-gen database by connecting off-chain storage with on-chain analytic insights. Our team is growing fast, backed by some of the top blockchain orgs and VCs.

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 decentralized supercomputer!

As a Sr. Software Engineer on our Cryptographic Protocol Engineering team you will be joining highly skilled engineers, cryptographers, and mathematicians 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 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. We also expect willingness to learn and research novel algorithms and techniques.

Responsibilities

Writing C++/ Rust (or other similar languages) code and math-focused algorithms to build a bigger, better, faster, more optimized SQL Proofing mechanism
Building strategies, tools, platforms and database integrations to rapidly test and iterate on various cryptographic techniques / commitment schemes / database designs / algorithms for outsourced Proofs of SQL
Codifying best practices for future reuse in the form of accessible, reusable patterns, templates, and code bases to facilitate meta data capturing and management
Cryptography/SNARK engineering research
Working with engineering leadership to define, prioritize, and ensure smooth deployments with other operational components

Skills & Qualifications

Bachelor’s degree in math, computer science, computer engineering, or related technical field. Masters or PhD is a plus.
3+ years software engineering experience (or academic research) around applied math programming
Fluency with the mathematics surrounding basic cryptographic primitives

Nice to Have

Understanding of elliptic curves and various cryptographic protocols. (Diffie–Hellman key exchange, commitment schemes, hashing, etc.)
Knowledge and experience with SNARKs is a huge plus. (Bulletproofs, Spartan, KZG protocol, sum-check protocol, FRI commitments, etc.)
Experience writing/developing novel algorithms (such as sorts, searches, divide-and-conquer, etc.)
Ability to clearly communicate developed algorithms (e.g. by using pseudo-code)
Ability to read and interpret research papers
Familiarity with a variety of languages (Rust, C++, Scala is a plus)
Familiarity with SQL/database design is a bonus
Passionate about Web3, blockchain, decentralization, and a base understanding of how SNARKs and arguments play into this
