At Jolocom you will:

  • lead API design efforts for the Jolocom-SDK

  • you will get the chance to work across a number of Rust and Typescript repositories / projects:
    1. primarily Jolocom-SDK, where you will be involved in developing new features, as well as iterating on / improving existing ones
    2. additional repositories integrated with the Jolocom-SDK (e.g. Jolocom Agent, DID Method implementations)

  • design and implement new features / APIs on the Jolocom SDK. Help with iterating on / improving existing APIs based on feedback from project partners, SmartWallet dev efforts, and personal assessment

  • coordinate documentation and testing

You may be a fit for this role if…

  • you are passionate and interested in software architecture and interoperability

  • you gravitate toward idiomatic, well-structured, readable, and testable code

  • you have persistent drive to make improvements and innovate, desire to have an impact by effectively managing conflicts and priorities, and by thinking creatively and solution-oriented

  • you are proficient in Rust and Typescript

  • you are fluent in English (German is a plus).

Extra points for:

What to expect from us:

  • a flat (horizontal) organization — we avoid top-down management

  • multi-product environment

  • realistic project estimation times

  • opportunities to come up with your own solutions for technical challenges around data flow, reactiveness and performance

  • an exciting cryptography-based product with incredible potential.

What it’s like to work at Jolocom?

At Jolocom we are on a mission to put people, organizations, and machines in control of their data using decentralized identity management technology.

We create software systems that resolve significant challenges in digital identity & access management while delivering person-first user experience.

We maintain a calculated balance between pragmatism (shipping code), deeply informed protocol design, and strict application of robust engineering principles.

Crucially, we believe in a collaborative approach to creation: at Jolocom we share a definitive appreciation for the transformative power of open source.

All of this happens in the heart of Berlin.

If you already have a smile on your face, it may be time to pursue your passion at Jolocom.
