About The Applicant

Early in their career but already able to contribute meaningfully to a production codebase. Cares about how things look and feel as much as how they work, and keen to learn more about cybersecurity, secure development, and building software for a hardware product.

They should be comfortable asking questions, but also able to take ownership of their work, break down problems, and move tasks forward without needing constant direction.

Must-haves

Around 1–2 years of experience in software development (commercial, internship, or substantial personal projects).
Strong JavaScript/TypeScript skills and confidence working with modern front-end codebases.
Hands-on experience with React and Next.js or Vite (building and maintaining components, pages, and basic data flows).
Some experience with Node.js on the backend and consuming or building REST APIs.
A good eye for design: attention to layout, spacing, typography, and interaction details.
Ability to translate designs (e.g. from Figma or similar tools) into clean, responsive UIs.
Comfortable using Git (feature branches, merge requests, resolving simple conflicts).
Familiarity with writing basic tests (unit or integration) and an interest in improving test coverage over time.
Clear written and verbal communication: able to explain what they’re doing and why.
Interest in cybersecurity and building systems that are robust and secure by design.
Nice-to-haves

Experience with LoopBack 4 or similar Node.js backend frameworks (NestJS is the proposed future implementation).
Previous experience working in an Agile environment (sprints, stand-ups, retrospectives).
Exposure to GitLab CI/CD or other CI/CD systems.
Experience with Docker or containerised environments.
Design skills using tools like Figma, Sketch, Illustrator, InDesign, or similar.
Experience building documentation dashboards, status dashboards, or admin-style interfaces.
Understanding of basic secure coding practices or awareness of concepts like the OWASP Top 10.
Experience working on products that interact with hardware, embedded systems, or IoT devices.
Comfort using AI coding tools to speed up development while still reviewing and owning the final code — not simply accepting changes without fully understanding what the code does.
Prior experience in a startup or small team environment.
