Role Description The AI Engineer builds the retrieval, evaluation, and workflow plumbing that makes Lena reliable. You'll work alongside the Senior AI Engineer on the reasoning layer, and across the team on integration into the broader platform. - Building and tuning RAG components: chunking strategy, retrieval scoring, prompt scaffolding, grounding heuristics. - Wiring evaluation harnesses that catch regressions on every release. - Working on the Python services that mediate between Lena and the rest of the platform. - Working with backend (.NET) and frontend (React) engineers to land AI-affecting changes safely. Qualifications - 1+ years of software / ML engineering experience. - Advanced in Python. - Shipped Python code that real users relied on (production or internal stakeholders). - Hands-on experience with LLMs, RAG, or AI workflows beyond tutorials. - Comfortable with REST APIs and JSON-based integrations. Requirements - 1–3 years of software engineering, ML engineering, or applied AI experience. - Hands-on exposure to LLMs, RAG systems, or AI workflows beyond tutorials or coursework. - Strong Python fundamentals; you have shipped Python that other people relied on. - Comfort with REST APIs, JSON structures, and modern SaaS systems. - Familiarity with prompt engineering and modern AI tooling. Benefits - Flexible / unlimited time off. - Health insurance. - Equity participation, discussed at offer. - Fully remote. - Architectural ownership of work that ships to real enterprise customers. - Direct working relationships with the people setting platform strategy. - A growth-stage platform where the decisions you make in your first year shape the product for years. - AI-assisted tooling licensed by NetSpeek (Cursor, Claude Code, GitHub Copilot, or comparable).

Title: AI Engineer [Trading Analytics & Data Engineering] Location: Houston, TX Department: PTS - SHELL Job Description: Join the ECI Group's Professional Technical Services Network as an AI Engineer [Trading Analytics & Data Engineering].
