Staff Site Reliability Engineer, FinOps

*** 100% Remote — Costa Rica (optional office access in San José)

Sumo Logic's FinOps team makes every dollar of cloud and AI spend visible, attributable and optimizable. As a Staff SRE, you'll apply SRE principles (measurement, observability, automation and accountability) to FinOps and cost optimization, treating cost the way SREs treat reliability. That means building the financial models behind our cost decisions: forecasting spend, modeling unit economics and COGS, and planning our commitment strategy. Working as the quantitative partner to Engineering, Finance (FP&A) and executive leadership, you'll turn those models into decisions.

This is a quantitative role . We're looking for someone who is genuinely comfortable with math, especially financial and statistical modeling. You will build forecasts, sensitivity analyses, and optimization models. You will draw insights from models and datasets, and must be able to defend the assumptions behind them when presenting to stakeholders.

FinOps & Financial modeling

• Build financial models for cloud and AI cost, including unit economics, COGS, and spend forecasts with scenario and sensitivity analysis.
• Shape our commitment strategy (CSP, RI, EDP) by modeling the tradeoff between savings and utilization risk.
• Design cost allocation and attribution methods so every dollar of cloud and AI spend maps to the team and product that drives it.
• Own and evolve our cost regression program and tooling, detecting, investigating and driving resolution of cost increases, so engineering teams have visibility into their spend and are accountable for it.
• Help shape and drive the cost optimization roadmap, leading cost-saving initiatives across teams and acting as the bridge between engineering, finance and executive leadership.
• Drive continuous improvement and operational excellence for our FinOps pipelines and tools.
• Provide mentoring and guidance to junior team members, fostering a culture of continuous learning and growth.
