Where Your Work Moves the Needle. At Pebl, every team member drives our success. Joining us means more than filling a role—you’re accountable for results and impact. Our values guide how we operate, execute, and collaborate across borders. By putting them into action, you’ll help us scale faster, compete harder, and lead the future of global work.

• Contributing meaningfully to Alfie’s core AI stack — working across model integrations, context management, prompt systems, and the retrieval pipeline that feeds Alfie accurate, grounded responses.
• Playing an active role in evaluation tooling: helping develop automated test suites, quality scorecards, and regression harnesses that let us measure Alfie’s performance and ship improvements with confidence.
• Diagnosing reliability and latency issues in production — tracing calls, profiling bottlenecks, and contributing fixes that improve system stability and scale.
• Working closely with the PM and engineering team to understand product requirements and contribute to the technical implementation.
• Contributing to internal AI tooling (Athena, Pebl’s employee-facing AI) on similar infrastructure and evaluation problems.

• Currently pursuing a BS or MS in Computer Science, Machine Learning, or a related field (or equivalent hands-on experience)
• Strong foundation in Python — you’re comfortable writing production-quality code, not just notebooks
• Working knowledge of LLMs and how they’re used in real systems — you understand context engineering, agent harnesses, tool use, and how model behavior is shaped by inputs
• Experience building or debugging backend services; REST APIs and async patterns are familiar territory
• Exposure to ML evaluation methods, testing frameworks, or observability tooling is a plus
• A habit of building with AI tools, not just reading about them

This is a 12-week internship in Palo Alto, CA.
