About Midnight:

IOG's Midnight Tribe is a business technology provider and core contributor to the Midnight Network, a blockchain platform for developing decentralized applications that safeguard personal and commercial data. The Midnight Network is the first blockchain to offer programmable data isolation by leveraging zero-knowledge (ZK) proofs to enable selective disclosure of what information is visible on-chain and is designed to help developers implement necessary business policies, such as meeting regulatory requirements.

What the role involves:

As a Senior Developer Relations Engineer, your primary focus will be building and maintaining example applications that demonstrate the versatility of Midnight's unique data protection and ZK-proof capabilities. These applications will highlight diverse use cases, providing developers with tangible examples of what's possible. You will complement this work by creating educational content to guide developers in building similar applications, empowering them to leverage Midnight's ecosystem to its full potential.

You will level up developers through education and enablement; we’re here to get developers excited about Midnight and to support them and their communities in achieving their goals. We build in front of the world; we're creative, and we embrace that energy to produce and share ambitious, inspirational projects with deep technical roots. By sharing authentic, engaging content with our communities, we're able to join in the conversations that matter to them and bring their stories home to help Midnight build better products. Those same discussions give us a chance to use our product expertise to make developer's lives better by helping them understand the value of zero-knowledge technology and how they can effectively apply it in their own projects.

We're developers, and we love to code. We code so we can speak from practical experience and join the global conversation. You'll be happiest on this team if you've lived the pain of pager duty and know the joy that comes from a beautiful green test suite. We're storytellers. We excite, engage, and empower developers. We're active members of our communities. We coordinate meetups, attend conferences, and help developers realize their collective strength. Collaborative personalities can expect to thrive here.

We value unique perspectives, and we absolutely encourage applications from candidates with backgrounds and identities that add to our spectrum of experience.

Given the nature of the work, this is a remote position. We're a results-oriented team, so our hours offer some flexibility.

Main Goals

• Design, develop, and maintain high-quality example Decentralized Applications (DApps) that showcase innovative and practical Midnight use cases, serving as a learning and inspiration resource for the developer community.
• Create educational materials, tutorials, and documentation that walk developers through the process of building DApps similar to the example projects, helping them understand Midnight's technology and its practical applications.
• Engage and build relationships with developers in the Midnight community to help them understand and build the DApps you’ve created.
• Respond to and support the developer ecosystem via various channels.
