Responsibilities

We are looking for a Managing Director to found and lead Infinity's Pension & Retirement Plan Actuarial business unit. You will be the credentialed actuary whose sign-off stands behind the work, and the leader who builds the client base and defines the offering. You will build a practice that carries far more plans per person than a traditional actuarial shop, with Infinity building the tools that take over the analytical labor.
This is an entrepreneurial role with real upside: you shape the service offering, the team, and the tooling roadmap, and you share directly in the value you create.
About the Practice
Pension and retirement plan actuarial work covers the calculations and filings that keep employer retirement plans funded, compliant, and properly accounted for: funding valuations, accounting disclosures, and regulatory reporting. All of it ultimately requires a credentialed actuary's sign-off.
The market ranges from large, fully integrated providers that bundle actuarial consulting with recordkeeping, participant payouts, and investment management, to boutique regional firms doing $10-30M a year in revenue that few outside the industry have heard of. In most organizations, much of the underlying analysis is already performed by non-credentialed analysts using proprietary or third-party calculation software, with the actuary reviewing and signing off. That split between credentialed judgment and analytical labor is exactly what Infinity's AI backbone is built to take over.
The work is regulatory and recurring: plans need annual valuations and filings regardless of the broader economy.
Lead the business unit: Run the Pension & Retirement Plan Actuarial BU end to end, including strategy, client relationships, quality, and financial performance.
Provide actuarial sign-off: Serve as the credentialed actuary of record, with sign-off authority on funding valuations and related work.
Originate and grow the client base: Bring a portable book of business, or build one quickly through your credibility and relationships.
Define the offering: Decide how narrow or wide to build the service, from purely actuarial consulting to something closer to the bundled model larger competitors offer. We expect you to have a strong opinion.
Decide what moves first: Identify which parts of the work (data preparation, funding and accounting reports, form completion) should move to an AI-driven workflow first.
Validate the calculation engine: Work with Infinity's engineering team on the approach to calculations. Near term, we expect to run existing third-party actuarial software in parallel with an Infinity-built alternative, validating that outputs match, and to retire the third-party tool once we trust our own.
