📋 Description

• Build and operate the real-time inference service that scores models for the risk decision engine, with low latency and high availability as first-class requirements • Own model deployment infrastructure — registry and versioning, CI/CD with performance, bias, and consistency checks, shadow mode, and staged rollouts • Build model observability: availability, latency, and error monitoring, plus drift detection as a retraining trigger • Partner with Risk Data Science to take models from a clean development-to-production handoff through to production operation under MLP ownership • Implement experimentation capabilities such as champion/challenger and canary routing, and explainability outputs like SHAP attributions • Feel a strong sense of product ownership and actively seek responsibility — we self-organize on small and medium projects, and we want someone excited to help shape and build a brand-new platform team

🎯 Requirements

• 5+ years in machine learning engineering, backend software engineering, MLOps, or a closely related field • Production ML service experience — deploying, serving, and operating models in low-latency, high-availability contexts • Strong backend engineering fundamentals in Python, with API frameworks like FastAPI or Flask • Experience with model deployment and lifecycle tooling: model registries, CI/CD for models, versioning, and staged rollout patterns (shadow, canary, champion/challenger) • Experience building observability and alerting for production services — latency, errors, and ideally model-specific signals like drift • Comfort with the data layer ML depends on: SQL, key-value/low-latency stores (Redis, DynamoDB, or equivalent), and streaming pipelines (Kafka, Kinesis, Redpanda, or equivalent)

🏖️ Benefits

• Competitive salary • Equity • Health insurance plans • Paid time off • Remote work options
