Junior Full-Stack Developer TypeScript / Next.js / PostgreSQL

Required:

• Working knowledge of JavaScript and TypeScript, and comfort building interfaces with React, from a job, an internship, coursework or your own projects. We do not mind which, but we will ask you to talk through something you built.
• Enough SQL to be dangerous: joins, aggregates, and the ability to read a query and say what it returns. Relational modelling fundamentals, keys, constraints, and why normalisation exists.
• Git, and the ability to explain a change in writing.
• Familiarity with the HTTP request/response cycle, JSON APIs, and browser fundamentals.
• Care about correctness. You run the thing. You look at the output. You are suspicious of a result that arrives too conveniently.
• Next.js or another server-rendered React framework particularly any grasp of the server/client boundary.
• An ORM or query builder (Drizzle, Prisma, TypeORM, Kysely, SQLAlchemy), and having written a database migration.

Preferred:

• Docker, or any exposure to containers and CI/CD.
• Any cloud platform — Azure preferred, though AWS or GCP experience transfers cleanly. Microsoft Certified: Azure Developer Associate is a plus, not an expectation.
• Tailwind, design tokens, or previous work against a design system.
• Testing, accessibility, or performance work of any kind.

Nice To Have, AI And Retrieval:

Some of our work involves LLM features built directly against the model APIs rather than through a framework. None of this is required and we will teach it, but experience is welcome:

• Azure OpenAI, or the OpenAI API used directly, chat completions and streaming.
  Tool / function calling: giving a model a set of functions and running the loop that executes them.
• Embeddings and vector search pgvector, cosine distance, chunking strategies, and the awkward fact that keyword and vector scores share no scale.
• Retrieval-augmented generation, and any experience evaluating whether a retrieval pipeline actually got better rather than just different.
• Prompt-injection awareness, or any thinking about what an LLM should not be permitted to do.

Explicitly not required:

• A computer science degree.
• Prior professional experience with our exact stack.
• Any prior AI or machine-learning experience.
