Principal Software Engineer

Principal Software Engineer – GenAI

We are looking for an experienced Software Engineer to help build the next generation of tools powering GenAI development. You'll join a small, highly collaborative team creating a lightweight, high-impact platform for tracking, evaluating, and improving AI-driven applications — from LLM agents to retrieval-augmented generation (RAG) systems and beyond.

This role is hands-on: you'll ship core features, design integrations with popular open-source libraries, scale backend systems, and work closely with users shaping the future of GenAI tooling. If you're passionate about building for developers, working fast, and solving real-world problems at the edge of AI innovation, this is the opportunity for you.

Key Responsibilities:

Architect and deliver clean, reliable client libraries designed for developer-first workflows

Build seamless integrations with popular LLM frameworks (e.g., LangChain, LlamaIndex, Instructor) to expand product capabilities

Design scalable backend systems to ensure high availability, low latency, and efficient data processing for GenAI applications

Develop interactive, user-facing features including AI evaluation dashboards, prompt testing environments, and dataset management tools

Collaborate directly with technical users to gather insights, validate product assumptions, and prioritize future improvements

Requirements:

4+ years of professional software engineering experience, with a strong foundation in building production systems

Fluency in Python

Experience developing AI/ML-powered applications or tooling, either professionally or through personal projects

Strong product intuition and the ability to ship quickly while maintaining high code quality

Comfortable working independently in a fast-evolving technical landscape; startup or early-stage experience is a plus

Bonus: Expertise in distributed systems, performance tuning, or large-scale data infrastructure (e.g., OLAP systems)
