AI Software Engineer

• Design, prototype, develop and maintain full-stack applications, primarily using TypeScript, Node.js and React. Choose the tools and languages that best fit the problem, and adapt quickly as requirements evolve.
• Work closely with the Chief AI Officer, internal users, product managers, designers and engineers to identify practical problems, test ideas and deliver useful tools in short iterations.
• Use AI coding tools and agent workflows extensively to accelerate implementation, debugging and testing, while taking ownership of code quality, correctness and maintainability.
• Integrate and maintain robust connections with third-party APIs and services.
• Participate in code reviews, architectural decisions, and continuous improvement initiatives.
• Move successful prototypes into dependable everyday use, with appropriate testing, performance, security and error handling.
• You know good UX, visual and good technical design when you see it and how to ensure quality is embedded in the software development process. 

• At least 2 years of proven experience as a Software Engineer.
• Hands-on experience using AI coding assistants and agents as a core part of your development workflow, including defining tasks, providing context, coordinating local or cloud-based coding workflows, and reviewing and validating generated code.
• Practical familiarity with integrating LLM APIs and AI services into applications, and the ability to learn orchestration and evaluation tools as needed. We value sound engineering judgment over expertise in a particular AI framework.
• Strong experience in back-end development with Node.js or a similar JavaScript runtime.
• Experience building frontend applications with React or a comparable framework, and the flexibility to work across backend languages and tools when the problem calls for it.
• Solid understanding of RESTful API design, OAuth, and integrating third-party APIs.
• Strong problem-solving and communication skills, comfort with ambiguous requirements, and a practical approach to experimentation: build a small working version, get feedback and iterate.

• Experience with TDD/BDD and writing test suites (e.g., using Jest, Cypress).
• Familiarity with agile methodologies and DevOps best practices.
• CI/CD pipeline experience (we use Gitlab CI/CD).
• Familiarity with cloud platforms like (especially AWS).
