About this role

Tellius enables organizations to get faster insights and act upon cloud-scale enterprise data using AI-powered automation. Any user can ask any question across billions of records via a ChatGPT-like interface, understand “why” metrics change via AI insights that surface hidden key drivers and trends, and leverage agentic flows to perform complex multipart analysis easily — in a self-service manner. Unlike traditional BI tools, Tellius excels at ad hoc analysis, deep dives, and business-friendly advanced analytics.

We’re looking for a Staff Software Engineer to join our AI team. This is a high-impact, IC-focused role for someone who wants to build scalable AI systems that power real-world decision-making.

What You’ll Do

  • Architect and implement core infrastructure for AI agents and orchestration (e.g., LangChain, custom frameworks)
  • Build and optimize backend services using Python and SQL to support AI workloads
  • Engage with design partners and early customers to validate architecture, use cases, and product direction
  • Develop robust data pipelines and work with large, complex datasets
  • Contribute to agentic application design, grounding LLMs in structured data and business logic
  • Collaborate with AI researchers, product managers, and design to ship production-ready features
  • Collaborate with and mentor junior engineers

What We’re Looking For

Must-Have Experience:

  • 2-6 years of professional software engineering experience
  • Deep knowledge of AI engineering and agent frameworks (LangChain, LlamaIndex, or similar)
  • Strong backend skills with Python, SQL, and database design
  • Experience working with data systems and building scalable infrastructure

Nice-to-Haves:

  • Experience with Spark, Scala, or distributed compute frameworks
  • Exposure to AI applications in B2B or enterprise environments
  • Previous experience at an early-stage startup
  • Familiarity with data engineering, ETL pipelines, or analytics workflows

Why Tellius

  • Work at the cutting edge of AI and decision intelligence
  • Small team, big ownership. Your work will directly shape the product
  • Opportunity to help define a new category: agentic business intelligence
  • Collaborative team with strong product-market momentum
