About the role

  • Learn, maintain, and troubleshoot existing public projects and “skills” built within Anthropic Claude, ensuring business continuity.
  • Optimise complex, multi-step prompts for financial services workflows, including compliance checks, suitability recommendations, and financial promotions.
  • Provide direct day-to-day user support — acting as a help desk when outputs degrade, context limits are hit, or nuanced follow-up instructions are needed.
  • Support a user base of 500+ people, including non-technical teams transitioning from traditional manual processes.
  • Document AI architectures, best practices, processes, and controls to formalise ways of working that are currently managed informally.
  • Assist in improving the technical foundations behind automated agents, including refining the combination of LLM logic with Python and JSON used for letter-writing and fact-file processing workflows.
  • Partner closely with the lead AI strategist to ensure knowledge transfer and reduce single points of failure.

Requirements

  • Strong hands-on expertise with the Anthropic Claude ecosystem, including model behaviour (e.g., Sonnet vs Opus), limitations, and advanced prompting techniques.
  • Proven experience in prompt engineering for complex, multi-step workflows in production environments.
  • Ability to read, understand, and maintain Python code and JSON used by AI agents.
  • Strong operational mindset: focused on stability, adoption, and day-to-day reliability — not only strategy.
  • Excellent communication skills and empathy for supporting non-technical users.
  • Familiarity working in a highly regulated environment (wealth management / finance), where accuracy and compliance are critical.
  • Experience supporting AI adoption programmes at scale (hundreds of users) (Nice to Have).
  • Experience building or maintaining LLM-powered internal tools (agents, workflow libraries, prompt templates) (Nice to Have).
Benefits
  • 100% Remote Work
  • WFH allowance: Monthly payment as financial support for remote working.
  • Career Growth: We have established a career development program accessible for all employees with a 360º feedback that will help us to guide you in your career progression.
  • Training: For Tech training at Zartis, you have time allocated during the week at your disposal. You can request from a variety of options, such as online courses (from Pluralsight and Educative.io, for example), English classes, books, conferences, and events.
  • Mentoring Program: You can become a mentor in Zartis or you can receive mentorship, or both.
  • Zartis Wellbeing Hub (Kara Connect): A platform that provides sessions with a range of specialists, including mental health professionals, nutritionists, physiotherapists, fitness coaches, and webinars with such professionals as well.
  • Multicultural working environment: We organize tech events, webinars, parties, and activities to do online team-building games and contests.
