Finance Solutions Engineer

About Abacum

Abacum is the leading Business Planning solution for finance teams to drive performance. By automating reporting, enabling collaboration, and simplifying planning and forecasting, we help finance teams shift from number crunching to driving strategic decisions.

Founded in 2020 by two former CFOs, we’ve grown into a global team of 100+ people across 30+ nationalities. Headquartered in New York, we have offices in London and Barcelona. We’re trusted by industry leaders such as Dish Networks, Strava, BetterUp, Kajabi, JG Wentworth, Abridge, Cortex, and hundreds more.

We have raised over $100m, closing in June 2025 our $60M Series B, led by Scale Venture Partners, with the strong participation of Cathay Innovation, Y Combinator, Atomico, Creandum, and angel operators from Adyen, Zapier, and Twitch.

Our mission is ambitious and we can’t do it alone - join Abacum as we build the future of Business Planning!

We’re looking for a commercially-minded finance professional to partner closely with our Sales team to build high-impact Proofs of Concept (POCs) for prospective customers. This role sits at the intersection of finance, go-to-market and product, translating real-world business problems into financial models and compelling narratives that drive deal success. In addition to building POCs, you will play a key role in owning and evolving our demo environments, ensuring they reflect our latest product capabilities and effectively support our GTM strategy.

What you’ll do

• Partner with Sales to design and build POCs that demonstrate value to prospective customers

• Translate customer requirements into Abacum models and beautiful dashboards

• Work across industries, quickly ramping on new business models and metrics

• Own and maintain demo environments, ensuring they are always up-to-date, reliable, and aligned with GTM needs

• Create new demo assets and use cases to support different segments, industries, and sales motions

• Bring new product developments into demo environments, translating features into compelling, real-world scenarios

• Help shape repeatable POC frameworks, demo templates, and playbooks

What we’re looking for

• 2–5 years experience in FP&A, Finance, Investment Banking, Consulting, or similar

• Strong financial modeling skills (Excel / Google Sheets proficiency is essential)

• Solid understanding of:

• SaaS metrics (ARR, churn, LTV/CAC, cohorts)

• B2B and/or B2C business models

• Ability to structure ambiguous problems quickly with a commercial mindset

• High learning velocity — comfortable picking up new tools (e.g. Abacum) fast

Nice-to-have

• Experience in pre-sales, solutions engineering, or customer-facing analytics roles

• Experience building or maintaining demo environments or product showcases

• Exposure to financial planning tools / BI tools

• Startup or high-growth environment experience

What makes this role unique

• You’ll sit closer to revenue than traditional finance roles

• Direct ownership of both deal-critical POCs and demo experience

• High impact on how the product is positioned and experienced by prospects

• Exposure to multiple industries and business models

• Blend of analytical depth + storytelling + product thinking

Benefits

- Competitive compensation including equity package

- Competitive vacation policy

- Access to Meditopia

- Hybrid working model and flexible working hours
