Property Tax Expert

Job Description:

Why Onni Capital Most property tax professionals spend a career inside a billable hours model where the incentive is to do the work again rather than to build something that does it once. Valorem is the opposite bet. You will have engineers. Real ones, using modern AI development tools, sitting in the same office, whose job is to build what you tell them the market needs.

Your expertise becomes leverage rather than capacity. You will also have an unusual proving ground. Onni's own portfolio gives you a large, real, and immediately available book of assessments to work on, which means the product gets tested against genuine complexity rather than sample data. And this is a product with a clear path. Valorem is one of the businesses Onni Capital intends to grow into a standalone company.

Being the domain authority in a software company at this stage is a materially different position than being one of many consultants in a practice.

How We Work Onni Capital is being designed as a high ownership, low bureaucracy team. We work in small project groups, test ideas quickly, put early products in front of users, and make decisions based on evidence rather than hierarchy.

• Challenge assumptions and communicate directly
• Take responsibility for outcomes, not simply produce recommendations
• Use modern AI tools to work faster and produce better results
• Share unfinished work early and improve it through feedback
• Move comfortably between strategic analysis and hands on execution
• Know when to continue investing in an idea and when to stop
• Operate effectively without a detailed playbook

This is not a role for someone who wants months of consensus building, a rigid job description, or a narrowly defined set of responsibilities. It is for someone who learns quickly, takes initiative, enjoys solving ambiguous problems, and wants to help build something from the ground up.

• Represent clients and Onni entities through the appeal process, including assessment authority negotiation and appeal board hearings
• Manage the appeal calendar across jurisdictions, including deadlines, filings, and evidence requirements
• Quantify and report tax savings achieved, which is the number the business is measured on
• Product Work directly with the product and engineering team to translate assessment methodology into product logic, including valuation approaches, comparable selection, and appeal argument structure
