  • The ability to explain a solution design end to end, including agent behaviour, data flows, identity, controls, approval points, and failure paths.
  • The ability to distinguish between Microsoft 365 Copilot, Copilot Studio, Power Platform, and pro-code solutions based on requirements and know when to escalate to architecture.
  • Experience delivering against imperfect enterprise estates, including legacy APIs, batch feeds, inconsistent entitlements, and systems with no consumable API.
  • Experience working within architecture governance, security review, and responsible-AI controls, and preparing the evidence those forums require.

Responsibilities
  • Lead discovery across business journeys, processes, applications, data sources, integration touchpoints, entitlements, and control requirements.
  • Produce problem statements, design principles, future-state journeys, process maps, solution designs, agent specifications, and role or operating-model impacts.
  • Decompose prioritised use cases into agents, topics, tools, actions, workflows, connectors, knowledge sources, human approval points, and operational controls.
  • Recommend and justify platform choices across Microsoft 365 Copilot, Copilot Studio, Cowork, Autopilots, and Power Platform, escalating to solution architecture when required.
  • Prioritise use cases based on value, feasibility, data readiness, risk, and complexity, and build business cases across financial, customer, operational, and risk outcomes.
  • Define MVP scope, sequencing, release plans, non-functional expectations, and adoption approaches.
  • Design, build, and test custom Cowork, Autopilot, and Copilot Studio agents, including topics, knowledge sources, actions, tools, triggers, channels, connectors, and orchestration behaviour.
  • Build Power Platform solutions across Power Automate, Power Apps, Power BI, and Dataverse, applying environment strategy, solution packaging, and application lifecycle management.
  • Integrate agents and automations with systems of record using certified and custom connectors, Microsoft Graph, Dataverse, and REST APIs.
  • Configure governed grounding and retrieval over SharePoint, Dataverse, Microsoft Fabric, and curated data products, managing retrieval scope, permissions trimming, data freshness, and provenance.
  • Implement approval, write-back, and reconciliation controls for actions that update systems of record, including rejection and resumption paths.
  • Design agent behaviour that fails safely, including fallback responses, escalation to a human, and handling of out-of-scope or low-confidence requests.
  • Apply Microsoft Entra ID and Microsoft Purview controls, including sensitivity labelling, data loss prevention, auditability, and retention.
  • Build human-in-the-loop checkpoints before client-facing activity, credit or risk decisions, and writes to systems of record, with evidence captured at each step.
  • Configure logging and traceability for prompts, retrieved context, tool calls, model outputs, approvals, actions, and exceptions.

  • Write and assure requirements, user stories, acceptance criteria, test cases, controls, and adoption plans.
  • Manage technical risks, dependencies, issues, scope changes, delivery quality, and tracked benefits.
  • Act as the day-to-day delivery lead for client stakeholders and present designs, progress, and technical decisions to steering groups, design authorities, and decision forums.
  • Lead small teams of consultants, analysts, AI engineers, and low-code developers; coach junior colleagues and set build and review quality standards.
  • Drive adoption and enablement through training, live builds, demos, champion networks, and practical governance guidance.

Simplify's Take

What believers are saying

  • EY's January 2026 acquisitions of couniq and Qiado expand public-sector and FAAS consulting.
  • EY's April 2026 agentic AI rollout strengthens audit quality and client delivery speed.
  • EY's Microsoft alliance and AI assurance services attract transformation work from regulated enterprises.

What critics are saying

  • EY paid £105.5 million over NMC Health in 2026, signaling recurring audit liability exposure.
  • KPMG, Deloitte, and PwC relentlessly poach EY partners after the failed 2021 split.
  • Agentic AI standardizes audit workflows by 2028, compressing billable hours and weakening junior leverage.

What makes Ernst & Young unique

  • EY-Parthenon ties consulting, assurance, tax, and transactions into one global client platform.

EY commits $100M to bonuses rewarding human skills alongside AI adoption

Ernst & Young's US division is allocating $100 million this fiscal year to bonus payments rewarding employees who demonstrate adaptability, innovation, and judgement. Individual spot awards reach $500, whilst employees or teams making significant contributions can receive between $10,000 and $25,000, five times the previous programme's ceiling. The initiative also covers AI experimentation. "What we recognise signals what we value," said Ginnie Carlier, chief talent and culture officer for EY Americas. The bonuses form part of a broader strategy to reshape employee development across all career levels. Other professional services firms are pursuing similar approaches. KPMG restructured its audit internship this summer to emphasise critical thinking, whilst PwC US introduced training combining AI proficiency with human qualities like empathy. EY reported AI-related revenue grew 30% year-over-year in 2025.

KPMG and EY win $579M UK civil servants training contract despite consultancy spending pledge

The UK Government has awarded a contract worth up to £456 million to KPMG and EY to train civil servants, the Financial Times reported, citing government procurement tracker Tussell. Under the arrangement, the firms will train officials across various skills areas, including AI, between 2026 and 2028. KPMG's share is capped at £319 million, representing almost a quarter of its total UK advisory net sales from last year. EY's portion is worth £137 million, equivalent to around 13% of its UK consulting revenue. The deal is the largest single contract awarded to Big Four companies since Tussell started tracking records in 2012. The previous record was a £322 million deal between the Foreign Office and PricewaterhouseCoopers in 2012.

EY's 'invisible' AI router cuts token costs by 60% by directing queries to cheaper models

EY has introduced an "invisible" AI router to manage internal AI spending, helping cut token consumption by up to 60% since its April rollout. The router sits behind specialised AI tools and directs employee queries to the most appropriate model for each task, rather than defaulting to the most powerful option. Token costs have become a growing concern as AI providers increasingly charge based on usage. EY's AI Pulse survey found that 82% of senior leaders at companies investing in AI were worried about token usage. The router has been deployed on department-specific platforms, including tax and risk functions, though not on the general Microsoft Copilot chatbot available to all staff. EY has also implemented token budgets based on employees' roles and departments. The firm's global consulting AI leader Dan Diasio said companies should focus AI investment on areas with the deepest impact rather than spreading resources thinly.

FRC fines EY $1.5M over Made.com audit failures before 2022 collapse

The UK's Financial Reporting Council has fined EY nearly £1.2m and audit partner Julie Carlyle £49,000 for failings in their 2021 audit of Made.com. Both received severe reprimands for breaching international auditing standards regarding going concern and deferred tax assets. The FRC said the auditors relied on management forecasts without sufficient challenge or adequate testing. Made.com, an online furniture retailer that listed on the London Stock Exchange in June 2021, entered administration in November 2022 after reporting a £35.3m loss. EY later disclaimed its opinion on Made.com's 2022 interim statements due to material uncertainty about the company's ability to continue operating.
