Position Overview

The Full Stack Python Developer will own and build end-to-end product features across both frontend and backend systems. You will work closely with technical leadership to rapidly prototype, iterate, and deliver AI-powered applications that help users interact intuitively with complex data. This role requires strong full stack engineering skills, experience integrating large language models (LLMs), and comfort operating in fast-moving, ambiguous environments where speed, ownership, and impact matter.

Key Responsibilities

• Own full-stack development across frontend (Next.js, React, Tailwind CSS) and backend (Python, FastAPI) services.

• Design and implement core user experiences, including chat interfaces, contextual document viewers, and interactive workflows driven by model reasoning.

• Develop backend services supporting agentic orchestration, retrieval-augmented generation (RAG) pipelines, caching layers, and telemetry for user interactions.

• Integrate and operationalize LLMs (OpenAI, Claude, or open-source models) within production applications.

• Work with search and indexing technologies such as OpenSearch to enable fast, relevant data retrieval.

• Collaborate closely with technical leadership to iterate rapidly based on real user feedback.

• Establish technical foundations for analytics, logging, monitoring, and future model fine-tuning workflows.

• Balance speed and code quality, delivering pragmatic, maintainable solutions without unnecessary over-engineering.

• Contribute to architectural decisions and help shape long-term product and platform direction.

Required Qualifications

• 5+ years of experience in full stack software development, operating at a senior engineer skill level or equivalent.

• Occasional travel to NYC required.

• Strong proficiency with modern frontend frameworks, including Next.js, React, and Tailwind CSS.

• Strong backend development experience using Python and FastAPI.

• Experience working with search infrastructure, such as OpenSearch or similar technologies.

• Hands-on experience integrating LLMs, including OpenAI, Claude, or open-source language models.

• Experience building or consuming RAG pipelines, vector search, and embedding-based retrieval systems.

• Ability to thrive in ambiguous environments and take ownership of projects from concept to production.

Preferred Qualifications

• Experience building financial tools, such as dashboards, screeners, analytics platforms, or investment research applications.

• Familiarity with financial data, earnings calls, SEC filings, or investment research workflows.

• Strong understanding of analytics, logging, and observability in modern distributed systems.

• Experience designing user-centric tools that help users reason about data, not just visualize it.

• Interest in or ability to learn the language and mindset of investment analysts.
