What you will do

About Gnosis Chain:

Gnosis Chain is the product of the merger of Gnosis and xDai. As one of Ethereum’s earliest sidechains, Gnosis Chain has quiet but significant real world usage and will embark on an aggressive technical roadmap with the objective of accelerating Ethereum. Gnosis Chain is also where Ethereum’s colorful and quirky spirit lives on, as the original home that incubated many defining projects like POAP, Burner Wallet, Dark Forest, and Perpetual Protocol. 


Gnosis Beacon Chain has over 100k validators and aims to be the third most decentralized blockchain. Gnosis Chain currently does not have a trustless bridge, which we are looking to remedy. A proposal by the 0xparc team for a zk light client based bridge passed in July and we know that other teams are working on trustless bridges as well.

Additionally, Hashi was launched earlier this year to provide a different approach to bridge security and became a core part of the Gnosis bridges roadmap. Hashi has received great support from the bridge community so far and several integrations and new features are in the works.

About the role:

  • Development of Hashi and trustless bridges, incl. smart contracts, application integrations and tooling (off-chain components & monitoring)

  • Contribute in shaping Hashi’s technical roadmap and expanding the product further

  • Work closely with third party teams on integrations

  • Own the production ready implementation and deployments of all related technical components

  • Work on the migration of the current bridges to a Hashi based infrastructure

Who you are

  • You have 5+ years of experience in full-stack development roles

  • You have 2+ years of blockchain development experience. Bridge protocol experience is a plus

  • You have extensive experience with software development best practices and methodologies

  • You have strong knowledge of software design, documentation and testing

  • You are a self-motivated individual with a can-do attitude who can lead a team project to success

  • You understand the bridge design space well

  • You understand the tradeoffs of bridge architectures and different implementations

  • You are able to communicate with different technical teams and stakeholders effectively

About us

Gnosis boasts an unparalleled track record of experimentation and building decentralized infrastructure for the Ethereum ecosystem. When Gnosis was founded in 2015, it focused on building prediction markets to enable worldwide access to accurate information. Today, as a DAO, Gnosis uses the products that it creates to transparently guide decisions on the development, support, and governance of its ecosystem. Safe, Cow Protocol, Conditional Tokens, Gnosis Auction, Zodiac, Agnostic Relay, and MEV Blocker are all products and protocols incubated by Gnosis.  


In November 2021, the xDai and GnosisDAO communities voted to combine their vibrant ecosystems to create the Gnosis Chain, an EVM compatible, community owned network that prioritizes credible neutrality. Secured by over 125k validators around the world, Gnosis Chain ensures a secure and resilient infrastructure. Users and developers on Gnosis Chain can also take advantage of familiar tooling and trust-minimized bridges to the Ethereum mainnet. Gnosis Chain employs the same execution and consensus layer clients as Ethereum, ensuring seamless integration with all future EIPs.


Most recently, we launched Gnosis Pay, the first decentralized payment network allowing web3 developers to integrate with a range of traditional payment schemes including Visa. Gnosis Pay allows users to spend their digital assets anywhere Visa is accepted with the same quick, seamless transactions they expect from a traditional debit card. 


Embrace the future of decentralized technology with Gnosis Chain, and join us as we continue to shape the next generation of web3 advancements. Together, we are building a decentralized ecosystem that empowers users and fosters global innovation.
