Job Description:

What You Will Do

Practice
  • Review property assessments across residential, commercial, industrial, and mixed use assets, and identify where an assessment is wrong and why
  • Build and argue appeal cases, including comparable selection, income approach analysis, cost approach analysis, and market evidence
  • 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
  • Define what good output looks like and set the quality standard the platform is measured against
  • Test the platform against real assessments and real appeals, and be honest about where it is not yet good enough
  • Prioritise the product roadmap from a practitioner's view of what actually saves time and what only looks impressive in a demo
  • Advise on jurisdictional expansion, including which markets to build for next and what each one requires


Commercial
  • Support sales, including demonstrations, prospect conversations, and technical credibility with sophisticated buyers
  • Onboard and support customers, including training and ongoing advisory
  • Build relationships across the property tax and assessment community, including assessors, appraisers, brokers, and industry bodies
  • Contribute to positioning and content that establishes Valorem's credibility in the market


What You Bring

  • Five or more years in property tax assessment and appeals, at a specialist consultancy, an assessment authority, an appraisal firm, or in house at a large property owner
  • A track record of successful appeals you can speak to specifically, including the argument that won and the savings delivered
  • Deep command of valuation methodology, including income, cost, and direct comparison approaches
  • Working knowledge of assessment legislation, appeal procedure, and evidence requirements in at least one major North American jurisdiction, with the ability to learn others
  • Experience across asset classes, particularly multifamily, commercial, and industrial
  • Genuine interest in technology and automation, and a willingness to spend real time with a product team rather than treating it as a distraction from the work
  • Demonstrated ability to use modern AI tools in analytical work
  • Strong written communication. Appeal submissions and client reporting both live or die on the writing
  • Comfort in front of clients, assessors, and appeal boards
  • Comfort working in a small, fast moving team building a product that is still changing
  • High personal standards for accuracy, quality, ownership, and follow through


Nice to Have

  • AACI, MRICS, CMI, or equivalent professional designation
  • Multi jurisdiction experience across Canada and the United States
  • Experience at a major property tax consultancy
  • Experience at an assessment authority, and the perspective that gives on how cases are actually decided
  • Experience with valuation modelling, data analysis, or assessment data systems
  • Experience building or specifying software as a subject matter expert
  • Existing relationships across the property owner and assessment community


What Success Looks Like

Success in this role is measured two ways at once: savings delivered for clients, and whether the product can increasingly deliver those savings without you in the loop.

Within the first 90 days:
  • You have reviewed a meaningful portion of Onni's own assessment portfolio and identified where appeals are worth filing
  • You have a documented view of where the platform's analysis is right, where it is wrong, and what should be fixed first
  • The appeal calendar across relevant jurisdictions is mapped, with deadlines and evidence requirements captured
  • The product team has a prioritised list of methodology improvements coming from you rather than from guesswork


Within the first year:
  • Appeals filed on behalf of clients and Onni entities have produced quantifiable, reported tax savings
  • The platform's comparable selection and valuation logic reflects real practitioner judgment rather than generic modelling
  • You can point to analysis that used to take a day and now takes minutes, at a quality you are willing to sign
  • Valorem has expanded into at least one additional jurisdiction, with the requirements properly built rather than assumed
  • Prospects who do this work themselves come away from a demonstration believing the product knows what it is doing
  • Customers are being onboarded and supported without every question escalating to you
  • Methodology, evidence standards, and jurisdictional requirements are documented inside the product rather than living only in your head


What Makes This Role Different

You will practice and productise at the same time. In a single quarter, you may be involved in:
  • Winning an appeal on a commercial asset and quantifying the savings
  • Sitting with an engineer to explain why the comparable selection logic is wrong
  • Testing the platform against an assessment you already know the answer to
  • Deciding which jurisdiction Valorem builds for next
  • Demonstrating the product to a prospect who does this work themselves and will spot anything false
  • Watching a piece of analysis that used to take you a day happen in minutes, and then improving it


The expectation is high ownership. You are the reason customers will believe this product knows what it is doing.

Salary Range:

$120,000
