About The Position

Greenfield opportunity to build search, recommendation, and knowledge systems from the ground up. Backend-leaning role focused on designing and scaling intelligent retrieval pipelines, data engineering, and AI-driven discovery across massive, messy document sets.

Requirements

• 5+ years of professional software engineering experience.
• Experience building search systems, data pipelines, or recommendation systems at a startup (ideally Series B/C).
• Background in data science, information retrieval, or recommendation systems.
• Hands-on experience with embeddings, vector search, or RAG.
• Strong backend development expertise with TypeScript / Node.js.
• Comfort working with large, messy, real-world datasets.
• Must be a US Person per ITAR.

Nice To Haves

• PhD or Master's in Machine Learning or related field (higher studies can offset some years of experience).
• Self-starter with an ownership mentality who thrives in a fast-paced startup environment.

Responsibilities

• Design, build, and scale backend services that power search, recommendations, and relevant data retrieval.
• Build and optimize data pipelines to ingest, normalize, and index large volumes of government and enterprise data.
• Create retrieval pipelines using embeddings to search and reason across thousands of documents (vector search, semantic retrieval).
• Solve entity resolution challenges across messy, real-world datasets — de-duplication, merging, cleaning, structuring.
• Own projects end-to-end: from technical design and implementation through deployment and iteration.
• Collaborate closely with product and engineering teams to deliver data-driven features.
