Abacum Senior Talent Acquisition Partner at Abacum owning a significant share of hiring and establishing operating standards for recruitment. Responsible for full-cycle recruiting and hiring process development.
Responsibilities
We're hiring a Senior Talent Acquisition Partner to own a significant share of our hiring over the next year.
This is a builder role. We are growing fast enough that the way we hired at 60 people will not hold at 200. You will partner with our Founders Office to establish the operating standards for how Abacum hires: scorecards, interview loops, data hygiene, and the reporting that tells leadership the truth about where hiring stands.
This is a role for someone who has carried a headcount number as their primary metric and knows exactly how they hit it. You will be given real ownership and be tasked with running searches end to end: from intake, to sourcing, through close.
As we continue to scale the team and this function, we are looking for someone not just to grow with us, but to lead us into the next phase.
Own a set headcount target across your requisitions, and the funnel math behind it: pipeline coverage, conversion by stage, time-to-fill, offer accept rate.
Run a weekly hiring update that leadership can make decisions from — what is on track, what is not, and what you need.
Flag risk early. We would far rather hear "this search is off track and here's why" in week 3 than in week 10 (backed with data of course!).
Full-Cycle Recruiting
Run searches end to end across multiple functions and geographies — intake, calibration, sourcing, screening, interview management, offer, and close.
Personally source. Build market maps, write outreach that gets replies, and open doors that inbound never will.
Close senior candidates against competing offers, including the ones where we are not the highest bidder.

Required
B2B SaaS experience, at a company that went through a real scaling period. Startup or high-growth environments strongly preferred over large, stable ones.
Genuinely full-cycle. You still source, and you can prove it — what share of your hires came from your own outbound, and how you found them.
Operational rigor. You have built something that outlasted you: a scorecard, an interview loop, a reporting cadence, an SLA people actually kept.
Comfortable disagreeing with senior people. You can tell a hiring manager their profile is wrong, or that the candidate they love is a no, and keep the relationship.
For Toronto-based candidates: experience recruiting for B2B software sold to finance teams — FP&A, accounting, billing, treasury, spend management, or close and consolidation.
The upside is real. We’ve raised over $100M with our most recent Series B in June of 2025 led by top-tier investors like Scale Ventures and Cathay Innovation. You'd be joining at the stage where equity means something and where your searches decide what this company looks like at 200+ people.
Hiring is the constraint on growth, which makes this seat matter. Your number is the company's number. Leadership will not just know who you are, they’ll turn to you for some of the most impactful business decisions we need to make.
Build it, don't inherit it. The talent function is being set up now, not maintained. You'll partner directly with the Founders Office to write how Abacum hires with a path to lead it in the future.
A real New York office, with people in it. We're headquartered in NYC and in the office Tuesday to Thursday and will be joining a team with infectious drive, energy, and hustle. We work hard but we work together.
Fast decisions, small politics. Founded by two former CFOs, so the company respects the numbers — including yours. Your impact here is capped by your ambition, not your title.
