About the role

Key responsibilities & impact

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.
Helping diagnose 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.

Requirements

What you’ll need

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 what gets passed in and when.
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
