Hyfen

Why developers love Hyfen:

• Fast-paced start-up environment 

• Cutting edge technologies

• Ability to have a huge impact on product and company whilst it grows

HYFEN builds ecosystem infrastructure that enables up-to-date data and streamlined processes, while greatly reducing operating costs and maintaining the privacy of individual ecosystem partners. They do this by staying at the forefront of technology, compliance and security. They have developed an approach to solution design where end-user experience, compliance, governance and technology are solved in iterative steps. Working together with all the parties in an ecosystem is a key success factor in this approach.

CTO of HYFEN is Karim Grini, who has been with the company since 2012 and a few months ago, helped replace HYFEN’s long-running blockchain solution with a more conventional setup. The solution now runs on an almighty relational database and a shiny set of backend services in cloud-native Java & JavaScript frameworks.

As a developer, you’ll be responsible for designing, building, and maintaining HYFEN’s state-of-the-art software services. You will work in one of our project teams to write reusable, testable, and efficient code and to implement high-availability applications. You’ll be responsible for ensuring the proper respect of security practices and data protection. You’ll be expected to discover, plan, develop, document, and maintain new and existing integrations and endpoints. You will have a key responsibility in our 24/7 operations, and be one of the drivers for the software architecture, tooling, and integration strategy choices made by HYFEN.

Fun fact: Did you know that HYFEN is named after an impressive natural phenomenon? A hypha (which translates as hyfe in Dutch) is a long, branching filamentous structure of a fungus, extending underground, that plays a crucial role in ecosystems across the globe.
