We're excited to continue the momentum by building a world-class app that delivers on its promise. With all systems fully architected, we're currently in the design phase and looking for experienced senior software developers to join our technical team and help build the app.

The Role We’re looking for a Senior Backend Developer to power our infrastructure, from scalable APIs to reliable cloud services. This role is perfect for someone who wants flexibility and future equity growth, and who thrives on building robust systems that scale.

What You’ll do

Build REST Services using C# and .NET Core.
Maintaining and developing server-side network components.
Maintaining the optimal performance of our central database and ensuring responsiveness to any front-end requests.
Collaborating with front-end application developers on element integration.
Writing efficient, reusable, and testable code used in high-performance applications.
Work as part of a cross-functional team to determine optimal API contracts, code reviews, internal infrastructure, and process enhancement.
Full-stack development capabilities are a plus.

What You’ll Bring

Strong experience with programming languages like C# / .NET, Python or Java.
Experience building services using REST or GraphQL.
Good understanding of the entire product development lifecycle.
Minimum 4 years developing web/mobile applications
Minimum 4 years’ experience working with relational and document databases.
4-5 years using C# / .Net Core in a professional capacity.
In-depth knowledge of JavaScript, frameworks, libraries, and web stacks
Experience with cloud native technologies such as Kubernetes, containerisation, microservices and Software-defined Infrastructure.
Great problem-solving skills and a team player.
Excellent analytical skills and good at time management.

💸 Compensation This is an equity-only opportunity, with no current salary. You will receive vested equity in Luupli based on your contributions. This role is flexible and part-time, with the expectation of transitioning to a paid full-time position following funding and launch.
