Junior Software Engineer (Backend + AI) About Newton Research Newton Research builds an AI-powered research and analysis platform used by enterprises to unlock insights from their data. Our platform connects to major data warehouses (BigQuery, Snowflake, Databricks, Redshift), runs autonomous AI agents that reason over structured and unstructured data, and presents findings through a rich interactive frontend. We're a small, high-output team where interns work on production code from week one.

2, Django REST Framework, PostgreSQL, Redis AI/ML: OpenAI, Anthropic, and Google LLM APIs; LangChain + LangGraph agent orchestration; sentence-transformers for vector embeddings; RAGAS for evaluation Data Science: NumPy, Pandas, Polars, scikit-learn, XGBoost, PyMC (Bayesian), Prophet, Plotly Frontend: React 19, TypeScript, Vite, Ant Design, TanStack Query, SCSS Modules Infra: Docker, GitHub Actions CI/CD, AWS (S3, ECR), MinIO, Sentry, RQ (Redis Queue) for async workers Testing: pytest with 4,700+ tests, Vitest, Playwright E2E, parallel execution via xdist What You'll Actually Do This isn't a "shadow an engineer and take notes" internship. You'll touch production code in a codebase with 7,700+ lines of Django models, complex multi-table relationships, and AI agent pipelines that call LLMs, execute tools, and reason over enterprise data. Typical intern-level work here looks like: Build API endpoints — Write DRF serializers and viewsets that serve data to our React frontend.

Our models have real complexity (JSONFields, custom managers, mixin patterns) so you'll learn to think about data modeling. Extend AI agent capabilities — Add new tools to our LangGraph-based agents. Understand how retrieval-augmented generation works by working on our memory system (vector embeddings + semantic search).

Write async task workers — Our RQ workers process everything from document parsing (PDF/Excel/PowerPoint) to LLM inference pipelines. You'll write and debug distributed task logic. Improve test coverage — We take testing seriously.

You'll write pytest tests with real database fixtures, mock external APIs with responses and moto, and learn to catch N+1 queries with nplusone. Ship frontend features — Build React components with TypeScript, wire them to TanStack Query for data fetching, and style them with SCSS Modules. Our frontend includes rich text editing (Milkdown), interactive charts (Nivo, Plotly, Highcharts), and virtualized data tables.

Debug AI output — When an agent hallucinates or a retrieval pipeline returns irrelevant results, you'll help diagnose and fix it. This is the skill that separates AI-era developers from everyone else. Who We're Looking For We're realistic: true full-stack engineers are rare at the intern level.

We're looking for someone who's strong on backend fundamentals, curious about AI, and willing to learn frontend.
