Job Description

We are a team of ex-NATO, Amazon, Nvidia, etc. and funded by world-class investors such as Atomico, Protocol Labs, Jaynti Kanani (Co-Founder of Polygon), Jutta Steiner (Co-Founder of Polkadot), Balaji Srinivasan (ex CTO of Coinbase), Jaan Tallinn (Co-Founder of Skype, early investor of DeepMind), Taavet Hinrikus & Sten Tamkivi (Co-Founders of Wise & Skype).

Job Responsibilities

Your main focus will be on designing, building and scaling our NFT infrastructure backend which handles writing/minting NFTs at scale across different chains. This means designing, developing and shipping end to end new and exciting smart contract features which other developers can use with REST APIs, scaling nonce handling to thousands of transactions per second, ensuring reliability even when a single chain goes down, etc. We are still relatively small team (but growing fast) meaning there's a wide variety of really hard technical challenges you can solve - from writing smart contracts end to end to scaling our real-time and low-latency NFT infrastructure which will span all the L1 top blockchains such as Ethereum, Polygon, Solana, Flow and layers 2's.
