Description
Your new role
From day one, as a Junior Full-Stack Software Engineer (all genders) you'll use AI as your primary development tool to build, debug, and ship real features that impact users. Working alongside experienced engineers, you'll gain hands-on experience with technologies such as iOS/Swift, backend APIs, and the NIA SDK while developing a broad understanding of modern AI-driven software engineering. Through collaboration, pair programming, and AI-assisted workflows, you'll learn how to design, build, and maintain high-quality software - not by memorising syntax, but by thinking clearly, asking the right questions, and critically evaluating the output.
We value intelligence, curiosity, and critical thinking more than a specific educational background or previous professional experience. We're hiring for potential, not perfection. This is an opportunity to grow into a well-rounded software engineer who leverages AI to deliver real value across multiple areas of development.

Strong logical thinking and problem-solving ability - you can break complex problems into clear steps Basic understanding of programming fundamentals (data structures, functions, control flow) - enough to evaluate whether code is correct Experience using AI tools (ChatGPT, Copilot, or similar) to build, learn, or solve problems Critical thinking - you don't blindly trust AI output; you verify, question, and improve it Curiosity and enthusiasm for learning new technologies and approaches Ability to communicate clearly and work collaboratively within a team Interest in understanding software systems across frontend, backend, and integrations
