Who Are We?Obol 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 14 members spread across 8 countries.The 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.The NetworkThe 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.Obol 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.Similar 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.The Obol Network develops and maintains four core public goods that will eventually work together through circular economics:The DV Launchpad, a User Interface for bootstrapping and managing Distributed ValidatorsCharon, a middleware Golang client that enables validators to run in a fault-tolerant, distributed mannerObol Managers, a set of solidity libraries for the formation of Distributed Validators tailored to different use cases such as DeFi, Liquid Staking, and Fractionalized Deposits Obol Testnets, a set of ongoing public incentivized testnets that enable any sized operator to test their deployment before serving for the Ethereum Main netSustainable Public GoodsObol 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.The 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.Obol is looking for a Finance Associate to help support the founder's office scaling the financial planning and reporting of the Obol Labs team.

About Art BlocksArt Blocks is a first of its kind platform focused on genuinely programmable on demand generative content that is stored immutably on the Ethereum Blockchain. Our team is a group of passionate builders focused on creating the best ecosystem for on-chain generative content. We are moving rapidly to create the platform for all kinds of generative design projects. To learn more about what we are building, please visit artblocks.io/learn, follow us on Twitter (twitter.com/artblocks_io), or come hang out in our community Discord (discord.gg/artblocks).Art Blocks has openings for curious and collaborative people who are excited about digital ownership and generative art. We are looking for candidates who are team-oriented and treat each other with kindness and respect. We are looking to fill roles for engineers with varying prior experience levels–your exact level of experience is less important to us than your general aptitude to tackle hard problems, your desire to learn, your ability to work within a fast-paced environment, and your willingness to collaborate as a team player.

We are hiring 1-2 engineers as we build Voluntas, a hybrid health tech / crypto company pioneering a new model for patients to interact with clinical research. We’ve secured a few contracts and built a basic MVP already, but these will be our first full time members of the team to focus purely on the technology build.

For the right person with a senior level of experience and drive, we’d bring you on to lead our technology build out and give you a co-founder level of equity / token warrants. We have a strong plan for our product roadmap – involving a simple front-end for patients to register, infrastructure / UI to earn and interact with our token, and so on – and would love for this person to work with us and take ownership over the technical build.

While we could list a tech stack we anticipate you’d likely use, the truth is that we will likely scrap most of our current MVP for the new product you build with us – so you’d be able to guide the stack we utilize. We do anticipate deploying our token on an EVM-compatible chain, so experience with web3 tooling and solidity code is expected. You would work with us across the full scope of our product and have the capability to bring on people to help fill engineering roles as we grow.

If you’re an entry-to-mid level engineer (with experience building crypto apps / coding in solidity), we’d be excited to bring you on to help us build out the product. You’d still get a significant amount of equity / token warrants and the ability to help guide our technology, grow the team, and develop into a leadership role within the company. 

Regardless of your experience level, we expect the right person to be execution-oriented, flexible, and excited to work across a range of product areas.

This is a remote position and we’re excited to work with the right people from anywhere. We’re located on the US East Coast, but your schedule is flexible and doesn’t need to match our hours. While we sometimes meet up in person, the company operates remotely. No travel required other than coming to team offsites (likely in the US) around twice a year.

Your total compensation package (cash + equity / token warrants) will depend on the experience you bring and your own preferences.

We expect this to be a full-time commitment (with vacation / time off allowances). This doesn’t mean you can’t be involved in other things, but the expectation is that this is your primary focus. With that said, we do anticipate bringing on limited-term and part-time technical help as well, so if you’re a good fit but only on a short term or part-time basis, please feel free to apply (but let us know that when you contact us).
