\nWho Are We?\n\n\nObol Labs is a remote-first research and software development team focused on Proof of Stake infrastructure for public blockchain networks. Specific topics of focus are Internet Bonds, Distributed Validator Technology, and Multi-Operator Validation. The core team includes 35 members spread across +14 countries.\n\n\nThe core team is building the Obol Network, a protocol to foster trust-minimized staking through multi-operator validation. This will enable low-trust access to Ethereum staking yield, which can be used as a core building block in various Web3 products.\n\n\nThe Network\n\n\nThe network can be best visualized as a work layer that sits directly on top of the base layer consensus. This work layer is designed to provide the base layer with more resiliency and decentralization as it scales. In this chapter of Ethereum, we will move on to the next great scaling challenge, which is stake centralization. Layers like Obol are critical to the long-term viability and resiliency of public networks, especially networks like Ethereum.\n\n\nObol as a layer is focused on scaling main chain staking by providing permissionless access to Distributed Validators. The network utilizes a middleware implementation of Distributed Validator Technology (DVT), to enable the operation of distributed validator clusters that can preserve validators' current client and remote signing configurations.\n\n\nSimilar to how roll-up technology laid the foundation for L2 scaling implementations, we believe DVT will do the same for scaling the consensus layer while preserving decentralization. Staking infrastructure is entering its protocol phase of evolution, which must include trust-minimized staking networks that can be plugged into at scale. We believe DVT will evolve into a widely used primitive and will ensure the security, resiliency, and decentralization of public networks.\n\n\nThe Obol Network develops and maintains three core public goods that will eventually work together through circular economics:\n\n\nThe DV Launchpad, a User Interface for bootstrapping and managing Distributed Validators\n\n\nCharon, a Golang based middleware client that enables validators to run in a fault-tolerant, distributed manner.\n\n\nObol Splits, a set of solidity contracts for the formation of Distributed Validators tailored to different use cases such as DeFi, Liquid Staking, and Fractionalized Deposits \n\n\n\n\nSustainable Public Goods\n\n\nObol is inspired by previous work on Ethereum public goods and experimenting with circular economics. We believe that to unlock innovation in staking use cases, a credibly neutral layer must exist for innovation to flow and evolve vertically. Without this layer, highly available uptime will continue to be a moat.\n\n\nThe Obol Network will become an open, community-governed, self-sustaining project over the coming months and years. Together we will incentivize, build, and maintain distributed validator technology that makes public networks a more secure and resilient foundation to build on top of.\n\n\nThe Role \n\n\nThe focus of this role is on developing and enhancing React-based web applications for interacting with the Ethereum blockchain to create Distributed Validators. This includes creating user-friendly interfaces, integrating with wallets, and ensuring the applications are absolutely secure and reliable.\n\n\nThe goal of this role is to enable the proliferation of Distributed Validators in the Ethereum Staking Ecosystem, by making them easy to create, view, understand, and interact with. This role requires working with agency and autonomy. It requires collaboration with cross-functional internal teams as well as dealing with external stakeholders. Obol’s Distributed Validator Launchpad, Obol’s static website, Obol’s typescript packages, and other applications will be under this role’s remit. \n\n\n\nResponsibilities\n* Develop and implement new features for our web applications using React, showcasing your expertise in creating user-centric solutions.\n* Collaborate with cross-functional teams, including product owners, designers, and QA engineers, to ensure seamless delivery of high-quality products.\n* Contribute to Obol’s coding standards, design patterns, and development methodologies.\n* Drive innovation by researching and adopting the latest trends and technologies in the React ecosystem, ensuring our applications remain secure, competitive, and cutting-edge.\n* Act as a technical mentor for junior developers, providing guidance and support to help them grow and excel in their roles.\n* Collaborate with external partners integrating Obol technology into their dapps using the Obol SDK.\n* Take responsibility for maintaining and enhancing our current products, including our component library (obol-ui) and DApp (dv-launchpad).\n* Improve the accessibility of our interfaces to all types of internet users.\n* Harden the security of our React software and its supply chain.  \n\n\n\nRequirements\n* Professional experience in React-based Ethereum Application Development (examples below).\n* What we use for React Development: Typescript, Next.js, React Hook Form, SWR, Zustand, @headlessui/react, stitches.dev, tailwindCSS and others. \n* What we use for Ethereum Development: Foundry, Hardhat, Ethers.js, web3-react, @obolnetwork/obol-sdk, @metamask/eth-sig-util, @0xsplits/splits-sdk(-react), @gnosis.pm/safe-core-sdk, @synthetixio/synpress, @chainsafe/(bls/discv5/ssz) and others. \n* Previous delivery of react websites that enable non-custodial, wallet-based interaction with mainnet Ethereum or a similar EVM network with more than $100k in value handled. \n* Knowledge of JS/TS security and testing best practices.\n* Knowledge of JS/TS CI/CD best practices.\n* Experience working with Agile Software Development methodologies.\n* Web3 professional experience.\n* Proven ability to maintain and contribute to Open Source repos \n* Timezone between UTC-2 to UTC+3 \n\n\n\nNice to have\n* Ethereum staking experience.\n* Node.js or other backend development experience.\n* Solidity development experience.\n* Familiarity with docker and/or running servers.\n* SQL/NoSQL experience.\n* Experience working in a distributed remote team.\n\n\n\nBenefits\n* Fully Remote Working and flexible hours.\n* Meet the team at our Annual Offsites.\n* Chance to attend crypto and staking conferences.\n* Working with the purpose of decentralising Ethereum.\n* Generous paid time off.\n* Budget for equipment.\n* Budget for training or education.\n\n\n\n\n\nThank you for your interest.
