Job Description

Core Responsibilities

• Independently lead complex optimization initiatives from problem definition and technical design through implementation, rollout, and outcome validation. Coordinate dependencies across teams, escalating material risks to appropriate stakeholders.
• Architect and build reusable software, data pipelines, dashboards, and automation; connecting cloud spend, resource utilization, unit economics, reliability, and engineering productivity across services.
• Partner with engineering and finance leadership, to define baselines, success measures, cost-benefit assumptions, and delivery options; validate realized savings, distinguishing recurring savings from cost avoidance.
• Diagnose systemic inefficiencies across distributed services and data platforms; lead improvements in compute, storage, data movement, capacity, and workload placement. Execute against the aforementioned goals; simultaneously ensuring platform performance and stability.
• Design and productionize AI- and analytics-enabled forecasting, anomaly detection, and operational automation. Evaluate accuracy, operating cost, security, and human oversight before scaling adoption.
• Contribute to the design and delivery of scalable, available, secure, and maintainable services using cloud-native patterns, infrastructure as code, CI/CD, automated testing, and observability.
• Own the technical quality of integrations between engineering telemetry, billing, financial planning, and reporting. Establish data contracts, reconciliation checks, lineage, and auditable metric definitions.
• Support capacity planning, cost allocation, tagging, chargeback, and forecasting processes that improve financial accountability and budget accuracy across engineering teams.
• Develop automated unit and integration tests, troubleshoot production and data-quality issues, and ensure solutions adhere to engineering, security, compliance, and operational standards.
• Mentor (more) junior engineers through design guidance, code reviews, and technical coaching; coordinate technical work on shared initiatives and promote adoption of reusable solutions.
• Communicate technical recommendations, delivery risks, financial assumptions, and measured outcomes to engineering and business stakeholders; identify follow-on opportunities and recommend priorities to Management

• Stay current on cloud cost-management practices, AI capabilities, data platforms, and engineering productivity tools; prototype and evaluate technologies that can improve operational efficiency.
• Consistent exercise of independent judgment and discretion in matters of significance.

• Demonstrated ability to independently turn ambiguous business objectives into technical designs, phased delivery plans, and measurable outcomes across multiple services or teams.
• Deep experience with at least one major cloud provider—AWS, Azure, GCP, or OCI—and demonstrated application of billing, utilization, allocation, and capacity data to cloud optimization decisions.
• Proficiency designing and operating cloud-native services with CI/CD, automated testing, and infrastructure as code using tools such as GitHub Actions, Jenkins, Terraform, or equivalent technologies.
• Experience with microservices, containers, and orchestration platforms such as Docker, Kubernetes, EKS, or OKE.
• Strong SQL skills and exposure to data and analytics platforms such as Snowflake, Databricks, Spark, Presto, EMR, PostgreSQL, or Aerospike.
• Experience building dashboards, automated reporting, data pipelines, or observability solutions using tools such as Datadog, Prometheus, ELK, Grafana, or business intelligence platforms.
• Ability to analyze technical and financial data, quantify tradeoffs, debug scoped issues, and turn findings into practical engineering actions.
• Strong collaboration and communication skills, including the ability to work effectively with Engineering, Finance, Product, Architecture, Data, Platform, SRE, compliance, and end users.
