Object Capability Engineer - MetaMask

Our mission is to unlock the collaborative power of communities by making Web3 universally easy to use access and build on.

Working with Consensys puts you at the forefront of an evolving paradigm transforming our society for the better. We fundamentally believe blockchain is the next generation of technology that can lay the foundation for a more just and equitable society.

Blockchain tech is just over 10 years old. Ethereum itself is still a toddler and we’re far from reaching our full potential. You’ll get to work on the tools infrastructure and apps that scale these platforms to billions of users.

You’ll be constantly exposed to new concepts ideas and frameworks from your peers and as you work on different projects — challenging you to stay at the top of your game . You’ll join a network of entrepreneurs and technologists that reaches the edge of our ecosystem . Consensys alumni have moved on to become tech entrepreneurs CEOs and team leads at tech companies.

What you’ll do

As an Object Capability Engineer your task is to implement an “ocap kernel” inside of MetaMask with which we intend to create APIs and user experiences that would otherwise be infeasible. This pioneering effort aims to enable mutually suspicious programs to interoperate in the same user interface without the possibility of interference or privilege escalation. Our ambition is to spread this paradigm provisionally named “secure composability” throughout and beyond web3.

You'll be working in a collaborative environment at the cutting edge of the Web JavaScript and web3. Technologies used in your day-to-day include the endo project and Hardened JavaScript (SES) developed by Agoric and MetaMask Snaps . Your work will be instrumental in improving the composability and developer experience of Snaps making it easier for them to introduce runtime dependencies on one another.

Would be great if you brought this to the role

• Use your knowledge of security-minded application development to build MetaMask’s ocap kernel and enhance our plugin system Snaps.

• Leverage your proficiency in API design to create delightful experiences for internal and external developer audiences.

• Use your well-honed learning abilities to quickly onboard to a complex domain and codebase.

• Apply your multiple years of experience in software development to help your team write beautiful software.
