Fractional CFO, retained engagements

About the role

This is a contractor engagement, not a salaried position. Numinor recruits senior fractional CFOs into our bench, then matches each contractor with Canadian companies that have signed on to a Numinor CFO retainer. You operate as an independent professional under your own corporation or sole proprietorship.

The book of business comes pre-warmed. Clients have already chosen Numinor and agreed to monthly fees. Your job is to deliver the work that earns the renewal, one to five engagements at a time, set by how much capacity you want to take on.

Numinor handles client acquisition, contracting, billing, collections, and the bookkeeping and tax work behind each engagement. You focus on the finance work only you can do.

Your first 60 days

• Days 1–14. Onboard to the Numinor playbook, templates, and tooling. Shadow two senior CFOs already on the bench. Set your capacity (one, two, or three engagements to start).
• Days 15–30. First client match. Numinor introduces you, sits in on the kickoff, and stays in the room until you are clearly the named CFO for that engagement.
• Days 30–60. Second match if you have capacity. Monthly working call with the head of CFO services to flag what is working, what is not, and where the next match should come from.

What you will do

• Act as the named fractional CFO for the clients Numinor matches you with.
• Build and maintain monthly board packs, KPI dashboards, and cash forecasts that founders and investors actually read.
• Run scenario planning: hiring decisions, pricing changes, fundraising rounds, exit prep.
• Sit on client board and investor calls. Field investor and bank questions on the client's behalf.
• Coordinate with the Numinor bookkeeping and tax leads supporting each engagement so the work moves on a single rhythm.
• Use Numinor's shared playbooks, templates, and tools. Contribute back to them as you find ways to make them better.

Who we are looking for

• Seven-plus years of senior finance experience, including time as a CFO, VP Finance, or director of FP&A.
• Direct experience with Canadian SMB or startup finance, including at least one fundraising cycle from the company side.
• CPA designation, or equivalent international qualification with Canadian working knowledge.
• Operating as an independent contractor through your own corporation or sole proprietorship, with appropriate insurance in place (or willing to put it in place before the first match).
• Available for at least one active engagement at a time, with the capacity to take on more as the match makes sense.
• Plain communicator. You make finance feel sharp to non-financial founders without dumbing it down.

Nice to have

• Prior experience as a founder, operator, or COO.
• Specific sector depth in SaaS, consumer brands, professional services, life sciences, or franchise networks.
• Investment banking or private equity background.
• Experience presenting to Canadian or US institutional investors.
• Bilingual (English and French).

Compensation

Per-engagement fees. You earn a share of each client's monthly retainer, typically CAD 4,500 to CAD 8,500 per engagement per month, depending on the tier the client is on and the complexity of the work.

Capacity is yours to set. Many of our CFOs run three to five engagements in parallel for total contractor revenue in the CAD 180,000 to CAD 360,000 range annually. Some take on more, some less.

Paid monthly. Numinor invoices the client, collects, and pays your corporation on the same monthly cycle as the engagement. No chasing clients for payment.

What we bring to the table

• A pre-warmed book of business. Clients have already chosen Numinor. You do not sell, market, or pitch.
• Operational backing. Numinor's bookkeeping and tax teams handle the foundation under every engagement, so you focus on strategic finance.
• Playbooks and templates. Board pack templates, 13-week cash forecasts, scenario models, data room structures. Reused, refined, ready.
• A senior bench around you. Other Numinor CFOs to swap notes with, plus a head of CFO services who runs quarterly working sessions.
• Continuity of client relationships. When you take on a client, they are yours for the length of the engagement. We do not rotate CFOs.
• No client acquisition cost. No advertising, no proposals, no sales cycles. Capacity is the only variable on your side.

Match process

1. Application review. We read every application.
2. Intro call (30 minutes). A conversation with the head of CFO services about your background and the kinds of engagements you want to take.
3. Working session (90 minutes). Walk us through a board pack or model you have built. Paid take-home if you prefer it that way.
4. Bench panel (60 minutes). Meet two existing Numinor fractional CFOs and one Numinor founder.
5. Contract and first match. Independent contractor agreement signed, then we match you with your first client within four to six weeks.

Average time from application to first matched engagement: six to ten weeks. We do not bench-warm CFOs we cannot match.
