Staff Software Engineer, AI
Confirmed on the employer's own hiring board on Oct 16, 2026. First seen by Alion on Oct 15, 2026.
ABOUT THE TEAM
Technology is at the core of what we do. The AI Core team at Basis Technologies builds Compass, the AI agent platform behind Basis. Compass agents plan and execute media planning, buying, and operations work on behalf of agencies and brands. We build the orchestration, tooling, and evaluation infrastructure that lets LLM-powered agents work reliably in a complex ad tech domain, and we expose the Basis platform to our own and our customers’ agents through MCP and A2A. The AI Core team also functions as an enabling team for all of Basis Engineering, developing the patterns and best practices for agentic and AI-assisted development that other teams build on.
WAYS YOU’LL CONTRIBUTE
As a Staff AI Engineer, you will be the technical lead for the AI Core team, specializing in the architecture and development of our agentic platform. Other ways you will contribute:
WHAT YOU BRING TO THE TABLE
Minimum of 8 years of professional software engineering experience, including recent experience shipping production LLM-powered applications or agent systems.
A track record of technical leadership, including owning the technical direction of a team or major system and influencing architecture beyond your immediate area of ownership.
Expert-level proficiency in Python, with a history of architecting production APIs and backend services and integrating with protocols such as MCP and A2A.
Deep experience building and operating production-grade agentic systems with frameworks such as Strands, LangChain, or the Claude Agent SDK, including asynchronous and event-driven patterns, prompt engineering, structured outputs, and techniques for improving agent reliability. Sound judgment on when to optimize for speed and when to invest in quality.
Experience with evaluation and observability tools such as Langfuse or LangSmith, including designing evaluation strategies from the ground up.
Fluency with AI coding tools (Claude Code, Cursor, Codex, etc.) as a core part of the development workflow, paired with strong judgment and full ownership of AI-generated output.
Proven ability to mentor engineers and to explain complex agentic systems clearly to engineers, Product and Operations partners, and non-technical stakeholders.
Thoughtful approach to collaboration, design, and decision-making that prioritizes equity, access, and continuous learning, and a commitment to creating inclusive, respectful environments where all voices are valued and supported.
