Come join 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 Compiler Engineer. A more technical description of what we do is below!

About the role:

As a Compiler Engineer, you will work primarily on two areas of our tech stack:

1. Compilation of programs targeting a custom cryptographic processor running on an FPGA

2. Translation of an assembly language into a ZK virtual machine.

You will also work closely with the hardware and cryptography teams to define both the instruction sets and high-level program representations. Being a self-starter is essential, as there are always a variety of challenges that need to be tackled. Your work will have a direct impact on our growth and success.

Locations supported:

We’re looking for candidates who are located between the USA East Coast and Central Europe time zones. Although we’re a globally distributed company, ensuring the team works in cohesive time zones is essential to our goals. Additionally, the company plans to get together ~one week per quarter in either New York City or Europe.

Necessary Qualifications:

• Significant experience writing compilers

• Strong proficiency in Rust

• Understanding of computer architecture and configuration

• Understanding of technology tradeoffs and a pragmatic approach to problem solving

• Strong written and verbal communications skills

• Ability to think across layers of abstractions

• Ability to work in a fast-paced startup environment

Bonus Qualifications:

• Familiarity with RISC-V

• Experience with non-standard ISAs

• Experience with hardware accelerators for AI/ML

• Understanding of zero-knowledge cryptography

• Experience with performance tuning and optimization

About us (deep dive):

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 [1]. 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 [2].

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 [3] [4], 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.
