Responsibilities
Design model training and inference workflows with clear versioning, lineage, and promotion criteria where models are part of the system
Define service responsibilities, interfaces, and data contracts that evolve safely
Specify behavior under retries, timeouts, partial failures, and dependency degradation
Choose consistency and durability guarantees that match risk, latency targets, and operational realities
Design the request path for predictable tail latency and controlled resource usage
Build and operate high-performance services and APIs that keep authentication reliable, secure, and fast at scale
Implement distributed services that are safe under concurrency and robust to duplicate and out-of-order events
Build real-time scoring and decision services with clear input/output contracts and bounded execution time
Build distributed training pipelines that scale, are reproducible, and produce auditable artifacts
Build pipelines that move data and model artifacts through validation, promotion, and release
Define automated quality gates for service changes and releases
Add checks for data quality, schema/contract adherence, and training-serving consistency where appropriate
Define acceptance criteria tied to measurable outcomes and production behavior
Ship changes with staged rollouts and rollback readiness as defaults
Coordinate multi-service releases with clear cutover and recovery plans
Use production signals to validate rollouts and trigger rollback when risk is high
Instrument the full path with metrics, logs, and traces that enable fast detection and diagnosis
Implement alerting that reflects user impact, not just component health
Lead incident response for your services, restore service quickly, and communicate clearly during events
Run post-incident reviews and close follow-ups that measurably reduce recurrence
Drive reliability work through SLIs, SLOs, and error budgets, and make tradeoffs explicit
Improve performance and cost through profiling, load testing, and capacity planning
Raise engineering quality through reviews, standards, and simplification of operationally expensive designs
Align across teams on interfaces, data contracts, and reliability expectations to reduce coordination friction
Evaluate new approaches when they materially improve security, performance, delivery safety, or operational simplicity
