Cryptography Engineer (Research)

Irreducible

Irreducible provides fast and cost-effective computation of zero-knowledge succinct proofs.

Join us at Irreducible as we accelerate the ZK revolution by supporting web3 networks with reliable and cost-efficient proof generation. We’re a high-performance cryptography startup (with an exciting hardware twist) looking for a talented Research Engineer. A more technical description of what we do is below!

Role Overview

As a Research Engineer on the Cryptography team, you will be working on Binius, our binary field proof system, both on the core open-source library and on applications of it. The responsibilities will include improving functionality, performance, and security of the cryptography code. Your days might involve implementing new cryptographic protocols, designing and implementing more efficient algorithms, and working on system architecture improvements. You will work on a cross-functional team, collaborating with cryptographers and software engineers to adapt and apply the latest zero-knowledge cryptography research. There may be opportunities to contribute directly to Irreducible’s cryptography research publications.

2. Proficiency with Rust
3. Understanding of software engineering best practices, especially testing
4. Ability to read and understand cryptography research
5. Deep familiarity with zero-knowledge cryptography concepts
6. Experience implementing cryptographic protocols
7. Mathematical aptitude, especially in linear and abstract algebra

Bonus Qualifications

1. Competitive programming experience
2. Experience with performance tuning and optimization
3. Understanding of fundamental blockchain concepts
4. Familiarity with software design patterns
5. Experience with computer algebra systems such as SageMath
6. Published cryptographic research
7. Experience with ZK circuit programming

Locations supported:

We’re looking for candidates who are located between the USA East Coast and Central Europe time zones.

We are also in the process of opening an office in Berlin, and are excited to support relocation, on a case by case basis. Once our office is open, we plan to bring the whole company together for ~one week per quarter in Berlin.

We have a globally distributed company, and ensuring the team works in a cohesive way is our main goal.

About us:

We’re building out a high-performance, cost-efficient compute stack for advanced cryptographic proofs, specifically zk-SNARKs. Verifiable computing with zk-SNARKs is taking off as a solution to the scalability and privacy limitations that today’s blockchains suffer from. A new wave of blockchain protocols that use zk-SNARKs to prove smart contract executions, such as Polygon zkEVM, Starknet, and zkSync, are already in production. We believe there is a big market opportunity to generate proofs for these networks at scale in a cost-effective way. There are lots of interesting performance engineering challenges we need to solve to keep up with the maximum device throughput.

We take the approach of co-designing hardware and software systems to accelerate SNARK generation end-to-end. Our first-generation tech stack uses FPGA accelerators running custom digital logic tailor-made for our use case.

We also conduct cryptography research to identify computationally efficient algorithms for verifiable computing. These research efforts produced a novel cryptographic construction based on towers of binary fields called Binius, which we are currently developing into a production-grade system.

Our team has cross-domain expertise and includes hardware designers, low-level systems software engineers, cryptography engineers, and data center specialists, several of whom worked in HFT previously.

NOTE: We can not sponsor visas of any kind at this time.

We are committed to creating a diverse and inclusive workplace where talented individuals can thrive and grow. We value the different perspectives, experiences, and backgrounds that each person brings to our team. Even if you don’t fit 100% of the job’s necessary qualifications, we’d still love to hear from you.
