Pluto is an applied cryptography organization that develops cutting-edge, developer and user-friendly tools for adding advanced cryptography to applications. We focus on leveraging zero knowledge protocols to expand the capabilities of what developers can do on-chain today. We are a hands-on, product-focused organization. We believe that cryptography holds the key to protecting the openness of the internet, and that's why we are dedicated to making cryptography as accessible as possible for developers everywhere.
We are a small team of builders. Our engineers previously worked at Uber, Stripe, Lockheed Martin and YC funded startups. Together with our investors Geometry and Variant, we are building at the frontier of Zero Knowledge Protocols. Our fully remote team is based in NYC and California.
We are hiring for a skilled Zero Knowledge (ZK) Circuit Engineer who will play a pivotal role in developing our advanced proving system. As part of our dynamic team, you'll be tasked with implementing and optimizing state-of-the-art cryptographic code, focusing on zero-knowledge circuits for private computation and proof generation. Your expertise in modern zero-knowledge proving systems, coupled with your systems programming experience and knowledge of cryptographic frameworks, will be crucial in innovating and advancing our cutting-edge products.
Your contributions will shape the product & technical strategy and present an opportunity to participate in building a new product from the ground up. We are looking for you if you have positive energy, an optimistic outlook about the future, and you are determined to get there. You embrace learning about new things and can pivot on the fly.
What you’ll be doing:
Implement and optimize open-source cutting-edge cryptography and complex zero knowledge circuits for proof generation and private computation, focusing on circuit construction and optimization.
Research and implement cryptographic academic papers, exploring novel techniques and ideas.
Development of open-source zero knowledge developer tools.
Work with systems engineers to integrate your circuits.
What we look for in you:
Strong math and cryptography background.
Deep understanding of modern zero knowledge proving systems and cryptographic primitives like zk-SNARKs (e.g., PLONK) and frameworks like halo2, r1cs, plonky2.
Strong knowledge of algorithms or optimizations.
Experience with Rust.
A high degree of ownership, taking responsibility for projects from inception to completion.
Nice to haves:
Experience in advanced cryptographic techniques like multi-party computation (MPC).
Experience building with trusted enclaves like Intel Software Guard Extensions (SGX) or other Trusted Execution Environments (TEEs).
Understanding of the internals of the Ethereum Virtual Machine (EVM) or other Virtual Machine architectures.
Experience with Solidity and smart contract development.
Experience building open-source developer tools.
