About Fermah Fermah is the universal proof generation layer. It functions as a marketplace, where the supply side comprises GPUs and FPGAs. On the demand side, Fermah can generate proofs for any instance in which ZK is used. Fermah is bringing moon math to the masses. Fermah was founded by Dr. Vanishree Rao . She has been designing and building ZK for over 15 years and has a PhD in cryptography from UCLA. Our seed round was co-led by the a16z CSX fund and Lemniscap .  We are building a world-class team that values delivering results with excellence and empathy. Job Description  We are seeking a passionate Cryptography Engineer to work on cutting-edge cryptography protocols that we believe is the missing piece for ZK adoption. The engineering team at Fermah proudly operates in an environment of shared accountability and without hierarchy. As an early team member, you will help shape not only the protocol, but also who we are as...

As a Senior Infrastructure Engineer at Irreducible, you will develop systems for deploying software and firmware images to our bare metal server cluster and help manage our software development environments. Our production infrastructure includes connected FPGA-based high-performance compute servers, monitoring and logging services, blockchain network nodes, and API gateways, spanning both a bare-metal deployment and public cloud environments like AWS and GCP.  Infrastructure team members work closely with the hardware engineers and systems software engineers to specify the production requirements and build tools to empower the team to ship code to production securely, efficiently, and with full confidence and transparency.
