Job Description

Job Requisition ID: 41833

• Build production AI and agentic capabilities for Deloitte’s next generation of Tax products

• Work in a start-up-like environment with the opportunity to develop new features
• World-class learning and leadership programs – to continually drive your career 

This is your chance to help shape how Deloitte and our clients use AI, data and automation to transform Tax. As an Applied AI Engineer in our Tax Transformation & Technology team, you will turn complex Tax processes into reliable, secure and testable AI-assisted solutions. You will combine large language models with deterministic tools, structured data and human review to build products that can be trusted in real Tax delivery.

What will your typical day look like? 

You will work across AI product design, backend engineering and data-intensive Tax systems. The focus is practical applied AI: building capabilities that are useful, explainable, monitored and secure for enterprise use.

The role involves:

• Mapping Tax workflows and deciding where to use AI, deterministic rules and human review
• Building LLM assistants, document intelligence and agentic automation for Tax
• Orchestrating agents using LLM APIs, tool calling, structured outputs and state management
• Building RAG pipelines across ingestion, chunking, embeddings, retrieval and grounding
• Building evaluations, reference datasets, monitoring and feedback loops for quality, latency and cost
• Implementing grounding, guardrails, access controls, traceability and human review to reduce hallucination and support responsible AI
• Building, deploying and supporting secure AI services across cloud, backend and enterprise systems
• Working with tax and engineering teams to turn complex tax requirements into reliable AI-enabled product features.

About the team

Deloitte’s Tax Transformation & Technology team builds and operates the products, platforms and engineering capabilities that are changing how Tax work gets done.

We believe the future of Tax will be powered by data, automation and AI. Our multidisciplinary team brings together Tax specialists, software and data engineers, product thinkers and AI technologists to solve complex problems and turn ideas into dependable production solutions.

We are modernising our shared Tax platform and rules engine while developing AI-powered products that support complex compliance and advisory workflows. You will join a collaborative engineering environment where quality, traceability and responsible innovation matter as much as delivery speed.

Enough about us, let’s talk about you.  

• Experience building production software, data or applied-AI products
• Highly proficient in Python and comfortable working across an AI application stack
• Hands-on experience with LLM applications, including prompting, structured outputs, tool calling, RAG and model integration.
• Experience implementing multi-agent systems using frameworks and patterns such as ReAct, self-reflection, plan-execute or hierarchical delegation
• Ability to combine probabilistic AI with deterministic logic, controls and auditability
• Experience evaluating AI systems using reference datasets, automated tests, regression and monitoring.
• Confidence working with APIs, structured data and data-processing workflows
• Understanding of secure software deployment, including cloud hosting, identity, data protection, logging and governance.
• Familiarity with CI/CD, source control, automated testing and modern software delivery practices.
• Ability to translate complex domain requirements into working product features working with engineering, product teams and business stakeholders.
• The following experience would be advantageous:
• Exposure to AI research, postgraduate study or evidence of staying current with AI engineering methods
• Data science experience using tools such as pandas, scikit-learn, PyTorch or TensorFlow
• Experience with agentic developer tools, such as GitHub Copilot or Claude Code.
• Exposure to Azure OpenAI, Azure AI Foundry, vector databases, Docker, Kubernetes or MLflow.
• Experience with JavaScript, TypeScript or another relevant language is valuable
