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 35 members spread across +14 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 Network

The 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 three core public goods that will eventually work together through circular economics:

• The DV Launchpad, a User Interface for bootstrapping and managing Distributed Validators
• Charon, a Golang based middleware client that enables validators to run in a fault-tolerant, distributed manner.
• Obol 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

Sustainable Public Goods

Obol 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.

The Role

The 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.

The 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.

Engineers who join the team in this role will be responsible for designing and implementing foundational components of the Omni stack. This involves working heavily with Golang, Tendermint, Eigenlayer, interoperability components, and off-chain services while also having responsibilities to collaborate with the wider engineering team to improve our overall architecture and code quality.

Responsibilities

• Develop our core software stack – consensus and execution layers, Eigenlayer integration, and messaging protocol – from the design stage all the way to production ready implementations. Primarily in golang.
• Build a modular interoperability standard that is highly secure while also being flexible enough to incorporate future innovations in the interoperability space
• Build a network of validators that leverages restaked $ETH to secure the Omni chain
• Design, build, test, deploy, and maintain our node software and off-chain coordinating agents to power our distributed network
• Improve the design of peer’s architecture through thoughtful, professionally communicated feedback.
• Contribute to open source projects and play a role in building out the crypto ecosystem at large.

Requirements

• 3-7+ years of experience in a backend software engineering role with Go
• 2-4+ years of experience developing a blockchain client / node that launched mainnet in production with > $50m at stake
• Experience architecting, deploying, and maintaining a production system with > $100m and/or 1m users at stake
• Extensive experience managing the software development life cycle for medium to large projects
• Experience with AWS, GCP or similar cloud providers
• Desire to keep up with modern best practices in software development and crypto, and shape our tech stack as we build out new systems and services
• Daily overlap with 9am-12pm EST

Competencies

• Autonomous — specifically seeks to take greater ownership and responsibility and thrives in their personal growth by doing so
• Action oriented — we are looking for people who take action by default, consistently driving forward progress without asking for permission
• An engineer in both thought and implementation — they must be able to design architecture and see it through to implementation
• Adaptable — thrives in ambiguity, able to quickly iterate and push forward as the business dynamically expands
• Highly intelligent — learns quickly and can participate in abstract intellectually engaging conversations
• Effective communicator — clearly articulates ideas and engages in debates in a productive manner that leads us to making better decisions

Nice to Haves

• Experience scaling out infrastructure for distributed services
• Experience building a system with a distributed consensus mechanism
• Deep understanding of the Ethereum Virtual Machine

Our benefits include competitive compensation, early stage equity allocations, team outings and unlimited PTO. In addition, you’ll join a team of high caliber team innovating at the frontier of crypto that work collaboratively to help one another accelerate their personal growth.

We are a mission driven company. We believe deeply that through software engineering we can build a self-sovereign society. In our day to day, we make decisions based upon our company values of Individual Autonomy, Long-Term Orientation and Open Access.

The future belongs to all of us, independent of our origins. Omni is an equal opportunity employer and does not discriminate on the basis of race, religion, color, sexual orientation, gender or any other status protected under federal, state or local law.
