• 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.
• Create awareness, drive activation, and foster engagement among the developer community to grow and maintain a thriving Midnight ecosystem.
• Investigate emerging needs of DApp developers that point to improvements for Midnight and associated tooling, ensuring excellent usability, continuous improvement, and ongoing responsiveness to our community.

Duties

• Coding: Spend significant time designing, coding, and maintaining example DApps that demonstrate Midnight's capabilities. These examples will span diverse use cases, showcasing data protection and zero-knowledge proof integrations. Additionally, contribute to relevant open-source projects and internal tooling to support the Midnight ecosystem.
• Developer Advocacy: Use the example applications you've built as core material to engage with the community. Speak at conferences, host live coding sessions, create video tutorials, and write blog posts to show developers how to build and innovate with Midnight.
