Staff Software Engineer

Join Sharpist, a fast-growing startup in the HR tech space. As a Staff Software Engineer, you will take ownership of business problems from concept to implementation, release, and measurement. You will work closely with engineers, users, and stakeholders to ensure that solutions are technically sound and grounded in real insight. You will also have the opportunity to make meaningful improvements to the developer experience and contribute to the team's knowledge sharing.

• Posséder un problème commercial et en être responsable, de la conception de la solution à la mise en œuvre.
• Utiliser les modèles de langage (LLM) comme un outil de travail central pour améliorer l'efficacité et la qualité des spécifications.
• Assurer la correspondance entre ce qui est construit et ce qui était prévu en travaillant directement avec les ingénieurs.
• You can spot what LLMs miss: a wrong abstraction, a brittle data model, a spec that looks fine until it hits production
• Fluent English (written and spoken)
• You think like a Product Engineer: you've had full ownership of feature development, defining the solution, not just building what someone else specified
• You can write a clear, technically grounded PRD, and you know what makes one bad
• You have a strong intuition for UX: what confuses users, what creates friction, what feels right
• You use AI/LLM tools as a core part of how you work, across specs, prototyping, and implementation, not as a gimmick. Self-directed experiments and side projects count as evidence
• Experience building AI/LLM product features (prompting, evaluation, guardrails)
• Worked in a B2B SaaS or HR tech environment
