The Mission
While most teams are still talking about AI-first engineering. We're doing it.
We're growing, and we're hiring two experienced Full-Stack Software Engineers to join our Experiences and B2B Platform teams. Wherever you land, you won't be a small cog in a big machine. You'll take features from idea to production and see your work make a real difference.
About the role
At Scalapay, AI-first is how we work every day, not a slide in a strategy deck. You'll write sharp specs and technical designs, AI coding agents like Claude Code take on the heavy lifting, and you direct, review and test what they produce. You spend less time on boilerplate and more on what great engineers do best: architecture, tricky problems, and making things fast, robust and scalable.
This role will be integral in designing, developing, and maintaining scalable and efficient applications leveraging AI.
What You'll Do
- AI Spec-Driven Development: Write clear specifications and technical design documents that AI coding agents implement from, then direct, review and test what the agents produce.
- Application Development: Design, develop, and maintain high-quality web applications using Node.js, TypeScript, and React.js.
- Database Management: Work with both relational (e.g MySQL) and non-relational (e.g., Dynamodb, Redis) databases, ensuring efficient data storage and retrieval.
- Testing: Write unit and integration tests to ensure code quality and robustness. Experience with frameworks such as Jest, or similar.
- Framework Utilisation: Leverage modern frameworks like NestJS and Next.js to build scalable and maintainable backend and frontend architectures.
