About Sharpist

Mission belief: You genuinely care about helping people. That's why you're here

Responsibilities

• Prendre en charge les fonctionnalités du produit, de la compréhension du besoin à la production.
• Collaborer avec les équipes Produit et Design pour transformer les insights clients en une expérience produit ciblée.
• Utiliser les outils d'IA et de LLM comme partie intégrante de votre flux de travail, tout en validant leur sortie.

Requirements

• You think like a Product Engineer: you’ve owned full feature development, including defining the solution rather than only building what someone else specified
• You can write a clear, technically grounded specification, and you know what makes one bad
• 6+ years of professional software engineering experience
• You have strong intuition for UX: you notice what confuses users, what creates friction, and what feels right

You speak and write fluent English

• You use AI and LLM tools as a core part of how you work across specifications, prototyping, and implementation, not as a gimmick. Self-directed experiments and side projects count as evidence
• Clarity: You write specs that don't need a meeting to explain
• Ownership: When ownership is unclear, you step forward. When you're blocked, you find a solution; you don't shift the problem up
• Judgment: You know when something is technically sound vs. technically plausible-but-painful
• Speed: You move fast without creating rework for others

Preferred

• Experience building AI or LLM product features, including prompting, evaluation, or guardrails
• Experience working in a Startup, B2B SaaS or HR tech environment
