Junior Software Engineer (Backend + AI)

Newton Research builds an AI-powered research and analysis platform used by enterprises to unlock insights from their data. The Junior Software Engineer (Backend + AI) will work on production code, build API endpoints, extend AI agent capabilities, and improve test coverage while gaining exposure to both backend and frontend development.

Responsibilities

• 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

Skills

• Solid Python fundamentals — you can write a class, debug a traceback, and reason about data structures without AI autocomplete
• Familiarity with web APIs (you understand HTTP methods, JSON serialization, request/response cycles)
• Comfort with Git (branching, rebasing, resolving merge conflicts)
• Experience with at least one database (SQL queries, basic schema design)
• Genuine curiosity about AI/ML — you've used LLM APIs, built a RAG pipeline, fine-tuned a model, or at least experimented seriously beyond just chatting with ChatGPT
• Ability to debug AI-generated code — we use AI tools extensively, but shipping broken AI output is worse than writing it yourself
• Django or Flask experience
• React/TypeScript exposure (even a personal project)
• Familiarity with Docker and containerized development
• Experience with vector databases, embeddings, or LLM orchestration frameworks (LangChain, etc.)
• Contributions to open-source projects
• A deployed project you can demo (we value this more than your GPA)

Benefits

• Permanent, Full-time
• Format: Hybrid — we value in-person collaboration but offer flexibility
