Job description

Software Engineer (SWE) — LLM Superuser

Uplift Trial Participant * * * ## About the Role We're recruiting an exceptional engineer to participate in a structured AI Uplift Trial — a research initiative measuring the productivity and quality gains that expert LLM usage confers on complex software engineering tasks. This is not a role for someone who occasionally uses AI tools. We need an LLM Superuser : a practitioner with deep, intuitive command of how frontier models think, fail, and excel. * * * ## What We're Looking For Engineering Baseline - 4+ years professional software engineering experience. - Strong proficiency in at least two languages (Python, TypeScript, Go, Rust, etc.). - Comfortable across the stack : APIs, databases, cloud infrastructure, application logic. LLM Expertise — This Is the Role - Expert command of prompt engineering : chain-of-thought, few-shot, ReAct, structured outputs, and beyond. - Experience building agentic systems : tool-calling loops, multi-step reasoning pipelines, orchestration frameworks. - Deep familiarity with context management : RAG, chunking, vector search, avoiding context degradation. - Ability to critically evaluate model outputs — catching hallucinations and subtle failures a casual user would miss. - Strong opinions about where LLMs genuinely help in engineering workflows and where they don't. * * * ## What "LLM Superuser" Means You can look at a hard engineering problem and immediately formulate an LLM strategy. You have a personal library of hard-won prompt patterns. You can explain _why_ an approach works — and adapt it on the fly when it doesn't. You treat the model as a collaborator you understand deeply, not a black box you poke randomly.
