Finance Manager, Construction & Infrastructure

The Finance Manager is a high-impact individual contributor within Aon’s Construction & Infrastructure Finance function, working at the intersection of financial reporting, strategic planning, and business partnership. This role sits at the center of how our finance team influences business decisions — turning complex data into clear narratives that drive action. Reporting directly to senior Finance leadership, this person will be a trusted thought partner to regional business leaders and a key driver of forecast accuracy, performance analysis, and continuous improvement across our reporting infrastructure.

This role is based in Chicago with flexibility to work remotely.

Aon is in the business of better decisions. At Aon, we shape decisions for the better to protect and enrich the lives of people around the world. As an organization, we are united through trust as one inclusive team and we are passionate about helping our colleagues and clients succeed.

What the day will look like

• Financial Reporting & Close
  • Oversee the monthly close process — managing billings, journal entries, and expense variance analysis at the regional and office level.
  • Maintain accurate, up-to-date revenue and expense forecasts at the office level across all financial systems.
  • Develop and deliver actionable performance narratives in coordination with US Regional Finance teams to ensure forecast alignment and clear communication of results.
• Business Partnership & Strategic Support
  • Partner closely with regional leaders to articulate key finance KPIs, identify performance gaps, and align initiatives with overall C&I priorities.
  • Challenge and support regional leaders in addressing budget shortfalls — analyzing revenue performance by product, industry, and market segment, identifying commission lift opportunities, and clearly articulating fee income across solutions.
  • Develop deep fluency in Aon’s key products, deal lifecycles, and market dynamics to pressure-test forecast assumptions and empower business leaders to act on opportunities and address risks.
• Process Improvement & Execution
  • Proactively identify gaps and inefficiencies in existing reporting processes — then own the design and implementation of improvements.
  • Execute time-sensitive, cross-functional requests with accuracy and a strong sense of ownership.
  • Drive transformation initiatives with rigor and follow-through, from planning through execution.

How this opportunity is different

This role is ideal for a finance professional who is equally comfortable in the weeds of a monthly close and in the boardroom presenting to senior leadership. You are intellectually curious, relationship-driven, and energized by the challenge of turning ambiguous data into clear direction. You don’t wait to be told what needs fixing — you find it, build the solution, and bring others along with you.

Success looks like:

• Positive, measurable impact on C&I group growth and profitability.
• Senior leadership receives reporting that is clear, actionable, and decision-ready.
• Transformation initiatives are executed on time and with lasting impact.
• Regional leaders view you as a trusted finance partner — not just a reporter of numbers.

Skills and experience that will lead to success

• 6+ years in financial strategy, FP&A, business unit finance, or a related function.
• Bachelor's degree in finance or related field.
• Proven track record of driving strategic initiatives — identifying opportunities, building relationships, and delivering change through focused execution.
• Experience in corporate planning, business unit finance, strategy, and operations strongly preferred.
• Strong analytical and financial modeling skills with a sharp eye for detail and accuracy.
• Ability to translate complex financial data into clear, concise, and compelling narratives for senior and executive audiences.
• Experience creating Board of Directors and executive-level materials.
• Excellent project management skills — able to manage multiple priorities under tight deadlines without sacrificing quality.
• Collaborative by nature with the ability to build trust and influence across all levels of the organization.
• Self-starter who anticipates needs, stays ahead of issues, and takes full ownership of their work.
• Inquisitive mindset — stays current on industry trends and continuously looks for better ways to work.
