FinOps Engineering

You will analyze cloud and platform usage, identify savings opportunities, develop scalable optimization tools, and work directly with IT squads to turn recommendations into measurable results. This role requires a strong combination of cloud engineering, data analytics, automation, financial reasoning, and stakeholder communication.

We are looking for someone who can go beyond dashboards: someone who can explain why an optimization is technically safe, demonstrate how its value was calculated, support its implementation, and verify that the expected benefit was achieved.

If you have hands-on experience with cloud cost optimization, Python or SQL, cloud billing data, automation, and engineering collaboration, we would like to hear from you.

Key responsibilities

Identify optimization opportunities

Analyze cloud usage, billing, configuration, metrics, and business data to detect opportunities such as:

Develop optimization tooling and automation

Design, develop, and maintain tools that identify, prioritize, and track savings opportunities.

Produce actionable recommendations

Convert analytical findings into implementation-ready recommendations for users and IT squads

Explain and defend recommendations

Present optimization proposals to both technical and non-technical audiences. The key points are the identification and evidences of each recommendation. It is crucial to assess and describe what are the potential impacts and how performance is protected. Then taken decisions facilitated by explanations must be recorded.

Partner with service or product teams

Act as a FinOps partner to application, infrastructure, data, AI, and platform teams

Measure and report optimization outcomes

Establish transparent metrics and reporting for the optimization lifecycle is the foundation to bring confidence in the decision process.
