Senior API Magician (Go)

Bee team

Swarm is a system of peer-to-peer networked nodes that create a decentralised storage and communication service. The system is economically self-sustaining due to a built-in incentive system enforced through smart contracts on the Ethereum blockchain.

Swarm aspires to shape the future towards a self-sovereign global society and permissionless open markets. On Swarm, applications can run autonomously yet securely in a planetary-scale deployment and execution environment.

Bee is a Swarm client implemented in Go. It’s the basic building block for Swarm Network. Bee provides low-level constructs for file storage, feeds, key-value stores and untraceable communication.

The Swarm Bee team strives to keep things clear and simple, making reasoning and discussions efficient. In a broader sense, this applies to everything we do.

Solid, well-tested code is delivered in an agile manner.

Key technologies are Go, libp2p, protobuf, leveldb, and go-ethereum, as well as various cryptographic libraries.

For the development of our client-facing APIs (HTTP and CLI), we’re looking for a strong candidate with experience designing and shaping APIs. Ideally, you should be fluent with API design principles, have experience with full-stack web development and are aware of the friction points of integrating application frameworks in browsers. You’ll get extra points if you understand web3 concepts and how they affect browser security models.
