Who Are We?
DV Labs is a remote 30+ member research and software development team with a vision to establish a credibly neutral, trust-minimised infrastructure layer for web3. Previously known as Obol Labs, our work on distributed validators (DVs) boosts the security, resilience, and decentralisation of the Ethereum network.
Our values & Culture
We live by our values - we are: reliable, secure, synergistic, and innovative. These values aren't just a set of ideals, they're the foundation of our culture and the key to our success.
At DV Labs, productivity meets work-life balance in perfect harmony - we promote flexibility, trust, and transparency. We believe in connection beyond screens. Our team stays ahead by attending conferences and gathers annually for an offsite event full of collaboration, teamwork, and fun!
The Products
DV Labs develops and maintains three core products:
Charon, a Golang based middleware client enabling multiple nodes or parties to run validators together, in a fault-tolerant manner.
Obol Splits, a set of solidity contracts assisting with the formation of Distributed Validators, by allowing the ETH bond and validator rewards to be split across multiple parties.
Supporting the Obol Collective
DV Labs supports the Obol Collective: a community dedicated to scaling Ethereum by strengthening the security, resiliency, and decentralisation of the consensus layer through the development and deployment of distributed validators.
As a Full Stack Engineer at DVLabs, this position focuses on the Obol SDK, Obol API and the DV launchpad.
The Launchpad is the primary interface for interacting with the Obol Network, and the infrastructure to back this interface will need to mature and scale as Obol grows into its public mainnet phase. The launchpad is a typescript stack, consisting of React + Next.js on the front end and Nest.js + MongoDB on the back end. At DV Labs, we are constantly seeking to improve our technology stack. Joining in this role you will have a unique opportunity to have a high impact in the technical direction and decisions of the product into the future.
You will be joining a highly agile team, with the ability to take ownership of deliverables and drive quality across the organization. You should be able to work cross functionally and have a desire to get involved across different parts of the technology stack.
This role aims to grow the DV Labs API and Launchpad into the most reliable and rich set of tools for creating, monitoring and analyzing Distributed Validators.
