As a Senior ML Engineer, you'll be building and owning the recommendation engine at the heart of our Kubernetes resource optimization product, StormForge, cutting our customers' cloud spend without putting a workload at risk. This is a critical hands-on position at the intersection of applied machine learning and production engineering, where the hardest problems are as much about data quality, guardrails, and knowing when not to recommend as they are about forecasting itself. You'll need to bring rigor and curiosity in equal measure, designing time-series models and the fallback strategies around them, proving their behavior through repeatable regression testing, and iteratively raising the ceiling on accuracy and safety as we discover and learn more about the workloads our customers run.
 

Responsibilities

• Own the recommendation engine end to end: model selection, algorithm design, preprocessing, and the guardrails that keep recommendations safe to apply to live production workloads. 
• Design, evaluate, and productionize time-series forecasting and statistical models (e.g., Prophet, percentile-based estimation) that right-size Kubernetes workloads across CPU, memory, GPU, and JVM heap. 
• Build and maintain the data-quality layer: detecting and filtering anomalies, load-test windows, startup spikes, and autoscaling artifacts from production telemetry before it reaches a model. 
• Define and continuously improve how we measure recommendation quality: regression testing against golden datasets, behavioral validation, and accuracy/safety metrics in production. 
• Investigate and resolve recommendation quality issues reported from customer environments, tracing them through data, preprocessing, and model behavior. 
• Serve as the team's machine learning authority: guide technical direction on ML questions, make model-vs-heuristic tradeoff calls, and clearly communicate them to platform engineers, product, and leadership. 
• Write production-grade Python for models and pipelines alike and share ownership of the surrounding service (message consumption, metrics ingestion, caching) with the rest of the team. 
• Prototype and validate new optimization capabilities (new resource types, new algorithms, new workload classes) from research through gradual, feature-flagged rollout.
• Stay current on time-series forecasting and resource optimization techniques, and pragmatically evaluate which are worth adopting.

Must have strong experience…? 

• Master's degree or higher in a quantitative field (Computer Science, Machine Learning, Statistics, Applied Mathematics). 
• 5+ years of software engineering experience, with at least 3 years building and operating machine learning or statistical systems in production. 
• Expert-level Python: you write typed, tested, production-grade code, and you're fluent in numpy or similar array-based numerical computing. 
• Hands-on experience with time-series analysis and forecasting: seasonality, trend decomposition, anomaly detection, and classical statistical methods (percentiles, distributions, smoothing), not just deep learning. 
• Experience testing ML systems rigorously: regression testing against known-good baselines, behavioral validation, and reasoning about numerical reproducibility. 
• Working knowledge of Kubernetes: resource requests and limits, autoscaling behavior, and what happens to a workload when it's under-provisioned (OOM kills, CPU throttling). 
• Comfort owning a production service, not just a model: queues, caches, retries, observability, and debugging issues in customer environments from logs and metrics. 
• Clear written and verbal communication: as an ML engineer on the team, so you must be able to explain model behavior and tradeoffs to platform engineers, product managers, and customers. 

Experience in the following is beneficial 

• Experience with Prophet or similar forecasting libraries. 
• Prometheus/PromQL and experience working with metrics at scale. 
• Cloud cost optimization, capacity planning, or infrastructure efficiency background 
• AWS (S3, Managed Prometheus). 
• Experience being the ML domain expert on a team of generalists.
