Senior Software Engineer Authentication

What youll do

• Design
• 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
• 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.
• Validate
• 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.
• Release
• 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.
• Operate
• Participate in on-call rotation including nights and weekends.
• Own after-hours production releases including rollout validation monitoring and rollback execution.
• 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.
• Improve and lead
• 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.

Who you are

• You have built and operated distributed production systems at scale.
• You write systems that handle concurrency duplication and out-of-order events without surprising behavior.
• You design for explicit failure modes safe retries and stable contracts.
• You can design for predictable tail latency and controlled resource usage in real-time request paths.
• You ship safely with staged rollouts rollback readiness and change discipline.
• You use observability to reason about production and instrument systems for fast detection and diagnosis.
• You can lead incident response and post-incident reviews and drive long-term reliability improvements.
• You have managed model lifecycle in production: versioning validation staged rollout rollback and outcome-tied monitoring.
• You have built or operated distributed training pipelines with reproducibility lineage and controlled promotion.
• You understand drift and training-serving skew risks and mitigate them with contracts tests and monitoring.
• You have built or operated real-time inference services in production.
• You communicate clearly document decisions and drive alignment on tradeoffs and success criteria.
• You can take ambiguous problems define scope and deliver steady progress while keeping the quality bar high.
• You actively seek out and remove unnecessary complexity understanding that simplicity is a prerequisite for reliability security and velocity at scale.
• Familiarity with voice authentication fraud detection or deepfake detection is a plus not a requirement.

Your skill-set

• 57 years of software development experience.
• Experience designing and implementing highly scalable cloud-based APIs.
• Experience with multiple programming languages such as Python and Go.
• Expertise in data structures algorithms and concurrency.
• Experience building and operating real-time distributed systems including patterns for resilient services such as backpressure idempotency timeouts and retry or circuit-breaking strategies.
• Experience working with production ML systems and MLOps (for example model deployment feature pipelines experiment tracking and model or data quality monitoring) is a strong plus but not required.
• 2 years of experience in DevOps practices towards deployment of SaaS services including hands-on experience with Jenkins and GitHub Actions; implementing and maintaining CI/CD pipelines; and managing and maintaining applications in a multi-container environment such as Kubernetes.
• Knowledge of different data storage technologies such as Redis and MySQL.
• Knowledge of Docker and container orchestration frameworks such as Kubernetes.
• Experience developing and maintaining services using AWS native products such as Kinesis DynamoDB and S3.
• Experience with observability and monitoring tools such as Prometheus Grafana and cloud logging and tracing.
• Linux proficiency.
