Fullstack Developer with Python, Flask/FastApi, Javascript

ROLE

As a Full Stack Engineer (Python + JavaScript/TypeScript), you will build and scale core product features that power the daily work of law firms across the globe.
This is a Python‑first role: you will spend most of your time designing and implementing backend services in Python, while also contributing to a modern front end built with Javascript and TypeScript.

RESPONSIBILITIES

• Design, implement and evolve backend services in Python (e.g. FastAPI, Django, Flask) that are secure, scalable and easy to maintain.
• Build and iterate on front‑end features using React and TypeScript, focusing on performance, usability and clean component architecture.
• Integrate AI‑powered capabilities into product workflows (retrieval, summarization, recommendations, agent‑like flows) in collaboration with the internal AI/ML teams.
• Own features end‑to‑end: from data modelling and API design to UI behavior, monitoring, alerting and performance tuning.
• Write high‑quality, well‑tested code and contribute to shared patterns, libraries and best practices across the engineering organisation.
• Participate in technical discovery and architecture discussions, challenging assumptions and helping shape the technical roadmap.

REQUIREMENTS

• Bachelor’s or Master’s degree in Computer Science, Mathematics, or a related technical field.
• Strong professional experience (3+) as a Software Engineer with a clear focus on Python as your main backend language.
• Solid experience building web applications end‑to‑end, ideally in product‑focused or SaaS environments.
• Deep understanding of web fundamentals: REST APIs, authentication/authorization patterns, data modelling, SQL/NoSQL, caching and performance.
• Hands‑on experience with at least one modern front‑end framework (ideally React) and confident using JavaScript and TypeScript in production.
• Engineering mindset: you care about clean abstractions, testability, observability and long‑term maintainability, not just “making it work”.
• Curious about AI and how to leverage it pragmatically in product features and in your own developer workflow (tooling, code assistance, automation).
