Senior Back-End Engineer (Kotlin or NodeJS), Wallet Services Full Time

Blockchain.com is the world’s leading software platform for digital assets. Offering the largest production blockchain platform in the world, we share the passion to code, create, and ultimately build an open, accessible and fair financial future, one piece of software at a time.

We are looking for either Kotlin or NodeJS developers (we’ll teach you the other one) who have experience working directly with blockchain protocols such as Ethereum RPC.  As a backend engineer on the Web3 Scaling team, you will be working on APIs that power our non-custodial wallet experience.  This includes building unified balances and transactions APIs that gather data from a multitude of blockchain networks and allow our clients to dynamically add new networks without releasing new code.  Additionally, you will be responsible for integrating with 3rd party vendors that provide data for crypto tokens, DApps and DAOs, as well as efforts to further centralize logic that currently exists on our wallet clients, into backend services.

As a Senior Back-End Engineer you should lead by example – driving the technical discussions, influencing the approach and making a positive impact on the team’s development by advocating the best engineering practices.
