Senior Full Stack Engineer - DApp Development

Who Are We?

Dv 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 +30 members spread across +15 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

Dv labs 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.
