As Twilio enters the "Unified Platform" era —consolidating SendGrid, Voice, and Messaging into a single unified SDK and Console—and accelerates the rollout of advanced platform features like Agent Connect and Conversation Relay , our R&D Finance organization is evolving its structure to move from tactical execution to elevated strategic partnership. In this high-impact role, you will serve as the primary autonomous finance partner for our R&D engineering and product teams.

This position requires an independent thinker who understands the underlying platform architecture and can translate technical platform adjustments into dynamic financial forecasting while navigating unpredictable, non-linear cloud billing layouts. Responsibilities In this role, you’ll: Strategic Business Partnership: Act as an autonomous finance partner to R&D, Product, and Engineering leadership. Lead cross-functional conversations to determine whether infrastructure cost surges are driven by healthy customer volume growth or inefficient engineering configurations. Cross-Functional Collaboration: Partner seamlessly across Accounting, Engineering, FP&A, and FinOps teams to ensure accurate COGS/OpEx accounting classifications and product-line allocation of cloud costs, while driving upstream process automation and data integrity. Dynamic Financial Forecasting: Lead the monthly and quarterly forecasting process for R&D hosting infrastructure. Build dynamic models capable of managing complex, non-linear cloud billings from major providers and LLM partners. Operational Variance Analysis: Conduct deep-dive variance analyses and link financial outcomes directly to usage changes driven by product/market dynamics, translating technical platform adjustments into clear financial impacts. Cost-Containment Optimization: Proactively identify engineering cost-containment opportunities and partner with product managers to design and track cloud cost-efficiency strategies while maintaining platform performance. Financial Modeling: Lead strategic projects, analysis, deepdives to drive ROI opportunities and costs reductions. Build flexible financial models to support scenario planning, product expansions (, and support data-driven investment trade-offs. Infrastructure Metrics Tracking: Track and analyze vendor spend patterns, cloud capacity utilization, and budget consumption across core R&D functions. Strategic Communication: Communicate complex financial analyses and technical cloud cost structures in clear, actionable ways to non-financial audiences and engineering stakeholders.
