Work with OptyxStack.
We are building a network of AI engineers, LLM/RAG specialists, and technical authorities for AI project recovery—wrong answers, hallucinations, cost, latency. Project-based and advisory models.
// New tech, new problems, new learnings every day. We move fast and learn together.
Open positions
AI Engineer
Production LLM/RAG pipelines, prompting, retrieval, eval frameworks. Fix wrong answers and hallucinations.
View detailsRemoteRAG & Retrieval Specialist
Embeddings, chunking, hybrid search, reranking. Fix wrong answers and low recall with measurable benchmarks.
View detailsRemoteAI Performance & Cost
Inference cost, TTFT/P95 latency, routing, caching. Token economics and pipeline optimization.
View detailsExecution Model
Audit-Led & Evidence-Driven
We don't guess. Every engagement starts with a baseline—cost/conv, quality score, TTFT, retrieval hit rate. You must be comfortable proving your work with before/after benchmarks.
Production AI & Continuous Learning
Our clients run LLMs, RAG, and AI agents in production. You'll work on real systems—and there's always room to learn. New models, new techniques, new benchmarks. The field moves fast; we grow with it.
01 / Core Engineering
AI / LLM Engineer
Production LLM/RAG pipelines, prompting, retrieval, reranking. Eval frameworks, golden sets, groundedness checks.
RAG & Retrieval Specialist
Embeddings, chunking, hybrid search, reranking. Fix wrong answers and low recall with measurable benchmarks.
AI Performance & Cost
Inference cost optimization, TTFT/P95 latency, routing, caching, context trimming. Token economics.
AI Observability & Eval
LLM evaluation harnesses, regression gates, monitoring dashboards, drift detection for production AI.
02 / Authority & Research
Technical Content Strategist
AI / LLM FocusTurn AI audits, eval results, and before/after benchmarks into structured, authoritative artifacts. You bridge the gap between raw metrics and case studies.
- Ideally ex-AI engineer or LLM/RAG practitioner.
- Comfortable with cost/conv, groundedness, TTFT metrics.
Research & Benchmark Analyst
AI Eval & BenchmarksDesign eval harnesses and golden sets. Run before/after benchmarks that actually mean something. Interpret cost, quality, and latency data for case studies.
Technical Editor / Reviewer
Contract-basedHelp us keep our content clear and accurate. Validate clarity, correctness, and signal-to-noise. Ensure our output respects the intelligence of engineering readers.
Developer Relations
Technical communitiesRepresent OptyxStack in deep technical communities. Share real findings and learnings—substance over hype. Connect with engineers who care about production AI.
Content Marketing Lead (Technical Authority)
Part-time / AdvisoryDefine content pillars aligned with our methodology. Ensure every piece of content builds authority, not just vanity traffic. This role is strategy-first.
