We’re working with an early-stage startup on a mission to make public web data more accessible for AI development.

The project is ideal for individuals who are curious, self-driven, and excited about decentralised infrastructure and data accessibility. The team is lean, highly motivated, and structured for autonomy - engineers are empowered to make decisions and take ownership from day one.

The Role

You are a Full Stack Engineer who excels in building robust, scalable applications and brings significant experience across both frontend and backend technologies. You'll join a small, high-performing team focused on delivering a seamless and impactful user experience.

  • Solid experience with backend development using contemporary server-side technologies
  • Familiarity with both relational and non-relational database systems
  • Deep understanding of full-stack application architecture, performance tuning, and scalability principles
  • Effective collaboration with cross-functional teams, including product, design, and engineering
  • Proven ability to write clean, maintainable code and deliver complete end-to-end features

What You'll Be Doing.

  • Develop and maintain both frontend and backend components of the platform
  • Collaborate closely with product and design teams to bring ideas from concept to production
  • Ensure application reliability, performance, and security across the stack
  • Participate in technical planning, code reviews, and ongoing architecture discussions
  • Continuously improve development workflows, tooling, and best practices
