Introduction

Ion Protocol is a price-agnostic lending platform that leverages provable validator-backed data to mint $allETH—an ETH denominated stablecoin.Ion Protocol’s mission is to create new and innovative methods to financialize validator-staked liquidity in the Ethereum DeFi ecosystem by building trustless infrastructure to assess validator credit risk. We are beginning our journey by building a price-agnostic CDP-supported lending market to support various types of staked asset-backed collateral ranging from the familiar LSTs (stETH, rETH, sfrxETH, etc.) to EigenLayer re-staking positions. As we accelerate the growth of the staking ecosystem, we work and collaborate with providers such as Diva Labs, Swell, Puffer Finance, prominent infrastructure providers (Obol, EigenLabs, etc.), and trustless infrastructure providers (Modulus Labs, etc.) to develop across a wide technical stack. 

Who we're looking for

As a backend engineer at Ion, you will collaborate closely with the engineering team to store and analyze data related to validator activities. Our lending market is powered by off-chain data analysis of the Ethereum consensus layer—that is brought on chain via ZK state proofs and zkML. We will create ZK state proof and zkML systems that will efficiently compute and verify consensus-layer information on Ethereum smart contracts.

This database will be used to supply critical off chain data to on-chain oracle contracts and also to analyze risk profiles of unique validators under different liquid staking providers and node operators. We are looking for developers with a deep understanding in infrastructure systems to reliably support billions of dollars of liquidity.

We are looking for a motivated developer that can aptly research and deploy extensive knowledge across DeFi, ZKPs, security, and contract architecture to create mission critical software.

Responsibilities

• Developing and maintaining infrastructure to store validator activities at the beacon chain level.
• Syncing Ethereum full nodes with off-chain databases to store validator related data such as attestations and slashings.
• Interfacing with on-chain oracle contracts to supply accurate consensus layer data to facilitate DeFi mechanisms such as liquidations.
• Researching and implementing zero knowledge state proofs, zkML provers and verifiers with other ZK developers who are creating state of the art zkML libraries.

Qualifications

• We're interested in candidates with one or more of the following qualifications:
• Experience in databases and languages such as MongoDB, Postgres, SQL, and GoLang.
• Experience with containerized DevOps tools and cloud services such as Docker, AWS ECR, Kubernetes, etc.
• Experience or familiarity with zero knowledge merkle inclusion proofs, or ZKML-based zk provers and verifier systems either in a theoretical or a practical scope.

Other nice-to-haves

• Experience working with Ethereum execution clients such as Geth, Nethermind, Besu, Erigon, etc.
• Experience working with Ethereum consensus clients such as Prysm, Teku, Nimbus, etc.
• Familiarity or interest in blockchain smart contract development and decentralized finance.

What you’ll like about us

• Working with team members with extensive experience in both blockchain engineering and crypto venture investing.
• Working with leading experts who are actively developing efficient libraries specialized for building decision tree based zkML provers.
• A fast paced team shipping product and researching novel mechanisms in decentralized finance.
• A focus on advancing employees’ personal career, network, and knowledge in the crypto ecosystem.
• Extensive network and partnerships with blue chip DeFi and blockchain infrastructure companies.
• A transparent, flat culture between teams.
• Remote work with an option to travel and work in-person with the team at crypto conferences and off-sites (fully comped).
• Both part-time and full-time roles are available.

Once we receive your application, we'll be in touch if we are interested.
