Toronto - Forward Deployed Engineer - Rapid Innovation Lab

At EY, we’re all in to shape your future with confidence. 

We’ll help you succeed in a globally connected powerhouse of diverse teams and take your career wherever you want it to go. 

Join EY and help to build a better working world. 

The opportunity 

We are seeking a high-performing Forward Deployed Engineer to join our Rapid Innovation Lab and rapidly prototype, validate, and deploy AI-powered solutions that transform how tax and business teams operate. This role sits at the intersection of artificial intelligence, AI-native development, and business transformation, turning practice pain points into working solutions in days rather than months. You will build with AI coding tools as your default way of working and help Tax professionals learn to build for themselves.

You will embed with tax professionals, business stakeholders, architects and technology teams to identify opportunities for automation, develop intelligent agent-based solutions, and integrate AI capabilities into business processes. The ideal candidate combines strong technical capabilities with a consultative mindset and a bias for speed and is passionate about deploying practical AI solutions that drive measurable business value. They care as much about whether a tool should exist as about how to build it.

If you don’t meet every requirement below but have a track record of building useful things quickly with AI, we encourage you to apply.

Your key responsibilities 

• Rapidly prototype and iterate on AI-powered solutions, intelligent agents and workflow automations that support tax and business transformation initiatives, using AI-assisted development tools (e.g., Claude Code, GitHub Copilot, Cursor) to move from idea to working demo in days.
• Embed with tax and business teams to understand challenges and identify high-value, repeatable processes worth solving.
• Develop custom integrations between AI solutions, enterprise applications, APIs, data platforms, and business systems, including MCP servers.
• Hand off validated solutions to engineering and platform teams for hardening and enterprise-scale deployment, with clear documentation and runbooks.
• Troubleshoot and refine solutions during pilots based on user feedback and usage data.
• Define success metrics for each build (e.g., hours saved, cost avoided, revenue enabled), track results, and recommend whether to scale, iterate, or stop.
• Apply firm security, data handling, and Responsible AI standards to every build, including human review of AI-generated code and outputs.
• Contribute reusable assets such as prompt libraries, templates, skills, and reference builds so the lab’s results compound over time.
• Collaborate with engineers, architects, and business teams to continuously improve solution effectiveness, usability and adoption.
• Coach tax professionals and other non-engineers to build and iterate on their own solutions with AI tools, acting as a force multiplier for the lab.
• Stay current on emerging AI technologies, AI coding tools, agent frameworks, and automation platforms to identify new opportunities for innovation.

Skills and attributes for success 

• Demonstrated fluency with AI-assisted development tools (e.g., Claude Code, GitHub Copilot, Cursor) as a primary way of working, with sound judgment about when to trust and when to verify AI output.
• Hands-on experience building, deploying or operationalizing AI agents, agentic workflows, copilots, or Generative AI solutions in business environments.
• A portfolio of things you have built and shipped quickly, such as side projects, hackathon entries, or workplace tools, ideally with real users or measurable impact.
• Practical software development skills using Python, SQL, or similar technologies.
• Experience with API development, integrations, and enterprise systems.
• Prompt and context engineering skills, including designing agent workflows and evaluating output quality.
• Experience working with cloud platforms such as Microsoft Azure, AWS, or Google Cloud.
• Demonstrated ability to take solutions from concept and prototype to user adoption and measurable value, including knowing when to stop.
• Strong debugging, troubleshooting, and problem-solving skills.
• Strong communication skills with the ability to translate technical concepts into practical business outcomes and to teach and coach colleagues without a technical background.
• Understanding of security, governance, risk management, and Responsible AI principles.

Ideally, you’ll also have

• Familiarity with low-code or workflow automation platforms such as Microsoft Power Platform.
• Understanding of tax or professional services workflows.
• Training or experience in statistics, data science, or quality assurance, including experience with sampling methodologies, error-rate analysis, and validating outputs across large data sets.

What we look for 

We’re looking for a collaborative and proactive team player who brings strong communication and relationship-building skills, along with a passion for AI, emerging technologies and business transformation. You’ll be someone who enjoys experimenting with new AI tools and ideas, is comfortable taking ownership and navigating ambiguity, and can move quickly to turn ideas into something useful and improve them based on feedback. Just as importantly, you value evidence over enthusiasm and are comfortable recommending when an idea should not be pursued.

This job posting relates to an existing vacancy within our organization.
