* Design and build APIs, UIs, and services using a modern stack including Next.js, React, Node.js, and PostgreSQL or similar.
* Collaborate to build intelligent features and decision-making workflows into user-facing products. Design and implement automated tests to validate and protect the quality and stability of the systems you work on.
* Lead by example, promoting high-quality coding practices, automated testing, peer reviews, and continuous delivery.
* Participate in team activities such as planning, retrospectives and reviews.
* Help lead technical discussions that drive better decision-making and outcomes.
* Mentor junior and mid-level developers, fostering a learning culture and helping others navigate complex technical challenges.
* Ensure strong observability, performance monitoring, and security are baked into everything we ship.
* Contribute to the technical vision of the product, evaluating and recommending new tools, libraries, and architectural patterns as needed.
* Support and evolve CI/CD pipelines, automated test suites, and deployment practices.
* Help enforce compliance standards such as data privacy, accessibility, security.
* Comfortable leading architecture discussions, participating in code reviews, and guiding team decisions.
Requirements
* A passion for building, shipping and supporting high quality software.
* Strong motivation to work with cutting-edge tools and development practices.
* Strong proficiency in modern full stack development, particularly with React, TypeScript, Node.js, Next.js, and database technologies such as PostgreSQL.
* Experience working with cloud infrastructure, preferably with Azure or Vercel.
* Solid understanding of software engineering principles, web architecture, and performance optimisation.
* Familiarity with integrating and consuming AI models via APIs.
* Experience building and consuming RESTful and/or GraphQL APIs.
* Knowledge of automated testing frameworks (e.g., Cypress, Playwright) and best practices for test-driven development.
* Experience with search technologies and indexing systems such as Elasticsearch, Typesense or Meilisearch with an understanding of performance, scalability, and relevance tuning.
* Ability to thrive in a fast-moving environment, balancing short-term needs with long-term scalability.
* Excellent communication skills, with a proven ability to collaborate cross-functionally and explain technical concepts to non-technical stakeholders.
Nice to have
* Proficient in the use of advanced development environments and AI-powered tooling such as Cursor, with an emphasis on increasing velocity, improving code quality, and leveraging contextual AI assistance in day-to-day engineering workflows.
* Exposure to incorporating LLMs into engineering workflows for production-ready applications, including prompt engineering and context management.
* Familiarity with multiple LLM providers (e.g. OpenAI, Anthropic, Google) and an understanding of their comparative strengths, trade-offs, and integration models.
* Experience with AI/ML toolchains such as OpenAI, Hugging Face, LangChain, or custom model serving.
* Demonstrated ability to work on greenfield projects, defining new patterns, processes, and tooling from the ground up.
* Experience with GitHub Actions, Terraform, or similar DevOps tooling.
* Familiarity with vector databases or hybrid search infrastructure (e.g., pgvector, Pinecone).
* Experience in data privacy, ethical AI, or governance frameworks.
* Familiarity with real-time applications using technologies like WebSockets or serverless edge functions.
