About the Role 

Island is scaling fast, and so is our finance function. We’re looking for a sharp, high-character FP&A Business Partner to join our Strategic Finance team at our Dallas HQ. This is a high-visibility seat partnering closely with R&D and G&A leadership, focused on building the scalable planning processes and metrics infrastructure that will carry Island through its next chapter of growth. 

Reporting directly to the VP, Strategic Finance & Investor Relations, you’ll be the embedded finance partner for R&D and G&A, translating spend, headcount, and investment data into the insights that drive real decisions. You’ll own planning end-to-end for your functions, build the reporting infrastructure that scales with us, and raise the bar for how finance operates across the company. 

Must be able to work on site at our Dallas HQ 5 days a week.

Planning, Budgeting & Forecasting 

• Lead annual budgeting and quarterly forecasting for R&D and G&A end-to-end, partnering with department heads to build bottoms-up plans grounded in operational reality. 

• Develop and maintain a rolling 12-month operating model for your functions that reflects real business dynamics, not just extrapolations. 

• Drive the monthly close process in partnership with Accounting, including variance analysis and management reporting. 

Business Partnering on Spend, Headcount & Investment 

• Serve as the trusted finance partner for R&D and G&A leaders, connecting day-to-day operational data to strategic priorities. 

• Provide proactive financial analysis to support decisions on headcount, vendor spend, tooling investments, and function-level resource allocation. 

• Frame trade-offs clearly so leaders can make better capital allocation decisions, faster. 

SaaS Metrics & Modeling 

• Develop a strong working understanding of core SaaS KPIs (ARR, NRR, churn, CAC, LTV, Rule of 40, payback) to effectively support planning and decision-making.  

•Partner with R&D and G&A to translate operational drivers into financial outcomes, linking spend and activity to unit economics and efficiency metrics. •Apply SaaS metrics to evaluate investments, inform forecasts, and support scenario analysis and strategic planning.  

•Leverage team-owned dashboards and analyses to provide insight, challenge assumptions, and improve visibility into business performance. 

KPI Tracking & Scalable Reporting 

• Own and continuously improve Island’s FP&A processes, tools, and reporting frameworks, with a bias toward automation and scale. 

• Evaluate and implement planning and BI tooling to level up the finance function as the company grows. 

• Build the models, templates, and playbooks that let the team move at speed without sacrificing accuracy. 

What We're Looking For:

Required 

• 7+ years of progressive FP&A experience with end-to-end ownership of the planning cycle, at least 2 years in a manager or senior IC role. 

• Strong analytical and business partnering skillset. You make your partners smarter about their business. 

• Comfortable operating in a high-growth, fast-moving environment where priorities shift and ambiguity is the norm. 

• Expert-level financial modeling skills. Your models are clean, auditable, and built to last. 

SQL/AI tooling experience and deep experience working with large data-sets

• Proven track record of translating complex financial data into clear, executive-level narratives. 

• Bachelor’s degree in Finance, Accounting, Economics, or a related field. MBA a plus. 

• Proficiency with NetSuite, Salesforce, Snowflake or equivalent ERP/CRM systems. 

Preferred 

• Deep fluency in SaaS business models and the metrics that drive them (ARR, churn, NRR, CAC, payback periods, unit economics). 

• Experience partnering directly with R&D and/or G&A functions.

• Familiarity with FP&A platforms (e.g., Pigment, Adaptive Insights, Planful) and/or exposure to emerging tools.  

• Proficiency with modern AI tools (e.g., ChatGPT, Claude, Gemini) to enhance analysis, automation, and decision support. 

The Kind of Person We're Looking For 

• You see ambiguity as an opportunity, not a blocker. You can build the plane while flying it. 

• You hold yourself to an exceptionally high bar on accuracy, on communication, on follow-through. 

• You're a trusted partner, not just a report generator. You make people smarter about their business. 

• You thrive in a fast-moving environment and know how to prioritize when everything feels urgent. 

• You're a quick learner, a team player, and genuinely a good person.
