We're hiring a mid-senior LLM Application Engineer on a remote monthly retainer to design, ship, and harden production AI pipelines for client products at Bolder Apps. You'll own structured extraction and classification systems that turn messy real-world inputs (email, HTML, PDFs, images) into reliable product data, with measurable quality gates, evals, and cost control. You'll work on Firebase / GCP-style backends with product, mobile, and QA. We want someone who has shipped LLM apps for real users, not demos. You should be strong across modern LLMs and especially fluent with Google Gemini (multimodal prompts, structured outputs, failure modes, and cost/latency tradeoffs), with solid experience on other major providers too. If you can hit hard quality targets, keep dollars-per-run honest, and leave runbooks another engineer can pick up, we want to talk.
