Min Experience: 6+ years

Location: Bengaluru

JobType: full-time

We are seeking a senior engineer who can work independently while collaborating closely with fellow developers and the Head of Engineering.

WHY THIS ROLE

  • High autonomy & ownership: Take full responsibility for features from start to finish — including design, architecture, implementation, testing, and deployment — with significant influence on product direction.
  • Broad technical exposure: Engage with the entire technology stack — utilizing Next.js 15, React 19, and Tailwind on the frontend; Node.js, TypeScript, Drizzle ORM, and Python 3.11+ with FastAPI on the backend; vector databases and RAG pipelines for AI search; along with DevOps practices for deployment and CI/CD.
  • Collaborative environment: Be part of a small, high-trust onsite team where your contributions are recognized and appreciated, working directly alongside the Head of Engineering and other engineers.


Requirements

RESPONSIBILITIES

  • 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).
  • Experience working with database technologies such as PostgreSQL and MySQL, along with ORMs like Drizzle ORM or comparable tools.
  • Familiarity with vector databases, graph databases, and retrieval-augmented generation pipelines; capable of integrating LLMs (OpenAI, Anthropic) into products.
  • Proficiency with DevOps tools including Docker, Docker Compose, GitHub Actions, and cloud deployment platforms like Railway or equivalents.
  • Ability to effectively incorporate AI into the product development process without introducing technical debt.

BONUS SKILLS (NICE-TO-HAVE)

  • Experience in building legal knowledge systems or search engines.
  • Knowledge of LangChain, LlamaIndex, or other open-source retrieval-augmented generation (RAG) frameworks.
  • Understanding of Elasticsearch, Weaviate, or other advanced retrieval technologies.
  • 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.
  • Quality & Reliability: You prioritize maintainable code and are committed to comprehensive testing and delivering a superior user experience.
  • Curiosity & Growth Mindset: You are eager to learn new technologies, such as vector search and LLMs, and contribute to the rapid evolution of a cutting-edge legal AI platform.

BENEFITS

  • High-impact Work: Your contributions will have a direct influence on the platform’s development and the broader legal industry.
  • Competitive Compensation: Salary scales with experience and includes paid holidays along with flexible work arrangements.
  • Learning & Growth: Gain hands-on experience with retrieval-augmented generation pipelines, vector databases, AI models, and large-scale data ingestion while growing alongside a scaling team.
