Armadin Security, founded by Kevin Mandia (founder of Mandiant, acquired by Google for $5.4B), is building autonomous proactive security solutions for the AI era. The company brings together researchers and engineers from Google, xAI, Meta, Stanford, Georgia Tech, Waterloo, Berkeley, and MIT to reinvent enterprise security.
As Senior FP&A Analyst for Services, you will own the financial engine behind services delivery—the people, partners, and hours that translate adversarial expertise into customer outcomes. You will build services cost and margin models from scratch, transform messy operational data into actionable decisions, and leverage AI to operate faster than traditional finance teams.
Key Responsibilities:
**Own Services COGS & Margin**: Lead the monthly services cost-of-goods-sold close, including variance analysis across labor, subcontractors, travel, and tooling. Build and maintain engagement-level and practice-level margin models covering assessments, red team engagements, incident response, and retainers. Track utilization, realization, billable vs. non-billable time, and bench costs to identify capacity losses.
**Shape Pricing, Scoping & Capacity Decisions**: Develop the services cost model that informs rate cards, fixed-fee vs. time-and-materials structures, retainer economics, and deal scoping. Partner with Services leadership on capacity planning, forecasting headcount and subcontractor needs against pipeline and backlog. Model the economics of new offerings, delivery models, and staffing mixes before launch.
**Be the Data Wizard**: Pull, join, and clean data across time tracking, PSA, CRM, HRIS, and ERP systems to build a single source of truth for services performance. Write SQL and scripts to build models, dashboards, and KPIs that leaders use. Surface signal in messy operational data: overruns, scope creep, underpriced work, and staffing inefficiencies.
**Make AI a Core Part of Finance Workflow**: Use AI and LLM tools daily to accelerate analysis, automate cost pulls and variance commentary, and generate reporting. Build AI-assisted workflows that enable faster closes and more confident forecasting. Evaluate and implement tools that raise the bar on planning, forecasting, and reporting.
**Drive FP&A Planning & Partner with Leadership**: Own the services portions of monthly close, quarterly forecast, and annual budget; build rolling forecasts for hiring, pricing, and resourcing. Present services performance and margin reviews to leadership and the board. Act as a true business partner on headcount, pricing, go-to-market strategy, and delivery scaling.
**Requirements**
- 5–7 years in FP&A or finance with direct ownership of professional services, consulting, or managed services costs, ideally inside a cybersecurity or technology company with a significant services arm
- Deep fluency in services economics: utilization, realization, blended rates, bill rates vs. cost rates, subcontractor management, and engagement-level P&L
- Data wizard skills: advanced SQL, advanced Excel or Sheets, and scripting (Python or similar); ability to pull your own data, build your own models, and automate your own reporting
- Strong, hands-on AI skills; already use LLM tools to work faster and can demonstrate how they've changed your analysis and reporting approach
- Startup operator mentality: self-directed, comfortable with ambiguity, and owns outcomes independently
- Clear communicator who can explain margin and cost drivers to practitioners, delivery leaders, and executives
**Nice to Have**
- Experience in the services finance org of a security leader (incident response, red team, or security consulting practice)
- Built a services margin or capacity model from scratch, or stood up services FP&A at a high-growth company
- Experience with Harvest or similar time-tracking and PSA tools
- Exposure to cloud, compute, or AI cost modeling
- History of working in high-autonomy, high-stakes environments
