Braintrust ( is a user-controlled talent network, where you keep 100% of what you earn and actually get to own the platform. We've been onboarding some big clients and specifically need a Tech Lead/Full-stack Developer for our client.  



Our client has built an immersive mobile app, to discover all things ethical and sustainable. It leverages a powerful curation platform they’ve designed based on decades of experience building and growing content companies.

They are a funded early stage startup seeking a stellar Full Stack Developer who loves to code iOS apps + supported infrastructure and is ready to build something for good.

Imagine a world where everyone can be a good human. A safe and secure community where conscious consumers can connect with others on the same mission and use their spending power to make a positive impact in the world. That’s the world they’re building. And they’re looking for people with integrity who are motivated by the idea of building a community with great positive impact.



If you are a Full Stack developer with front-end and back-end experience, who is passionate about building something that can have a positive impact on others and the world, they need you.

Core Responsibilities:

  • Work closely with CTO/CPO
  • Define, design, develop, and implement high quality software solutions in all layers of the application stack, from infrastructure to front-end
  • Design protocols, algorithms and APIs between system components including server/client interactions and APIs
  • Support and enhance a consumer-facing MOBILE app (iOS and Android)
  • Manage external developer team for special project


  • Attention to detail
  • Experience with at least one backend framework (e.g. React, Vue, Angular, Laravel)
  • Experience developing iOS and Android apps

The top traits they look for in candidates are voracious curiosity, positive attitude and a sense of mission. They love people who attempt to do things that their resume says they're unqualified to do and things that would scare normal people in their position.

This isn't their first time as startup founders. They've set out to create a very intentional, high-performance and mission-driven culture. They work long hours, but they try to practice good self-care, and encourage all team members to do the same.


Qualified candidates will be invited to do a screening interview with the Braintrust staff. We will answer your questions about the project, and our platform.  If we determine it is the right fit for both parties, we'll invite you to join the platform and create a profile to apply directly for this project.  

C2C Candidates: This role is not available to C2C candidates working with an agency. If you are a professional contractor who has created an LLC/corp around their consulting practice, this is well aligned with Braintrust and we’d welcome your application.  

Braintrust values the multitude of talents and perspectives that a diverse workforce brings.
