at Lucis
Paris, FranceOn-site
Responsibilities
- - Build lightweight internal tools: Automations, scripts, small apps, or integrations that remove repetitive work.
Requirements
- THE ROLE Over the last year, AI went from “helpful tool” to something closer to a new kind of teammate: capable of drafting, coding, analyzing, and operating across many steps when given the right context and guardrails.
- We think the next step-function in startup speed will come from teams that operationalize AI well: - Not one-off prompts. - Not a few power users. - But repeatable workflows that the whole company trusts and actually adopts.
- We are hiring a Context Engineer / Applied AI associate to make Lucis meaningfully faster and higher quality by embedding AI into how we work.
- WHAT YOU’LL DO - Audit how Lucis uses AI today: What works, what breaks, where it is risky, and where it can be 10x better.
- - Ship a Lucis AI playbook: Prompt patterns, examples, do’s and don’ts, safety guidance, and “how we know it works.” - Roll out 5–10 high-leverage workflows: Across engineering, product spec, support ops, growth, and clinical content.
- You’ll fit in well if - Have 3–6+ years in product engineering, platform/devex, technical enablement, or applied AI, with clear evidence of shipped outcomes.
- - Are a power user of modern AI tools (Claude, ChatGPT, Cursor, Copilot, v0, etc.) and can explain when they fail and what you do about it.
- experience with LLM patterns (prompting, RAG, tool calling, agents) and evaluation approaches.
- - You’ll help define our AI operating system from early days.
- At Lucis, AI isn't just our product, it's our engine. 100% of our teams are equipped with the best AI agents.
- You have carte blanche to explore and automate everything that can be, so you can focus exclusively on high-value work.
Benefits
