Company Description

Turn analytical thinking into AI impact in Tax & Legal. At Deloitte.

Job Description

• Map existing Tax & Legal processes with practitioners and break them down into logical steps, inputs, decision points and outputs
• Turn practitioner expertise into structured logic: decision rules, data models and extraction specifications the engineering team can build on
• Write, test and iterate on prompts for large language models, and compare approaches using data rather than gut feel
• Design and run systematic evaluations: build test sets, measure accuracy and consistency, find failure patterns and propose fixes
• Work closely with developers on solution design, testing and releases to deliver end-to-end solutions
• Support practitioners in piloting and adopting new solutions; gather feedback and turn it into improvements
• Document workflows, test results and design decisions so solutions can be reviewed, governed and reused across countries

Qualifications

• A Bachelor's or Master's degree in engineering, natural sciences, mathematics, computer science, econometrics or a similar analytical field
• 0–5 years of experience; recent graduates with relevant projects, research or internships are welcome
• Strong analytical and structured thinking: you enjoy taking something messy and making it logical
• Genuine interest in AI and how it changes knowledge work; hands-on experience with LLMs, prompting or AI tools is a plus
• Basic programming or data skills (for example Python, SQL or advanced Excel) are a plus, not a requirement
• Eagerness to learn a new domain and comfort asking questions of senior experts
• Clear communication in English, written and spoken
• Comfort working in an international team where priorities evolve as solutions mature
