-   Design and develop features for new modules, including legal research casebase search, agentic workflows, practice management tools, and Word integrations.
-   Create and maintain data ingestion and retrieval pipelines by embedding legal documents into vector databases (Pinecone, Qdrant, Milvus) and integrating large language models (LLMs) for natural language search capabilities.
-   Collaborate with other engineers to ensure seamless integration across the technology stack, uphold code quality, and deliver projects on time and within budget.
-   Participate in DevOps activities such as managing Dockerized environments, setting up CI/CD pipelines (using GitHub Actions), and deploying applications to platforms like Railway or similar PaaS providers.
-   Write clean, well-documented, and reliable code, incorporating appropriate testing and performance optimizations.

**TECHNICAL REQUIREMENTS**

-   7 to 10 years of professional software engineering experience, preferably in high-autonomy or startup settings.
-   Strong expertise in JavaScript/TypeScript, React/Next.js, Node.js, and Python (FastAPI/Pydantic).

-   Ability to effectively incorporate AI into the product development process without introducing technical debt.

-   Experience with prompt engineering, model orchestration, or performance tuning.
-   Previous work in legal technology, fintech, or enterprise SaaS products.

**WHAT WE’RE LOOKING FOR**

-   **Ownership & Accountability:** You take initiative, independently manage your projects, and consistently deliver high-quality work without the need for constant supervision.
-   **Collaboration & Communication:** You work effectively with others, communicate your ideas clearly, and remain open to feedback and iterative improvements.
