Senior Machine Learning Engineer

• I (MLOps/LLMOps)

• As a Senior Machine Learning Engineer

• MLOps/LLMOps, you will design, build, and scale production-grade infrastructure and platforms that enable the full lifecycle of ML and LLM systems. You'll architect robust pipelines for model training, evaluation, deployment, and monitoring while ensuring reliability, observability, and efficiency at scale. This role collaborates closely with ML Engineers, Data Scientists, and Product teams to operationalize AI/ML solutions from prototype to production. Remote candidates will be considered. Ability to participate with fellow ML staff in-office at the company HQ in Redwood City, CA when needed is preferred.

Responsibilities:

Platform & Infrastructure:

• Design and implement scalable MLOps/LLMOps platforms supporting the full ML lifecycle: data versioning, model training, evaluation, deployment, and monitoring

• Build and maintain CI/CD pipelines for ML models and LLM applications with automated testing, validation, and rollback capabilities

• Develop infrastructure-as-code (IaC) for reproducible, version-controlled ML environments

• Architect model serving infrastructure with auto-scaling, A/B testing, and canary deployment capabilities

LLM Operations

• Build platforms for LLM fine-tuning, prompt management, and experimentation at scale

• Implement evaluation frameworks for LLM performance, quality, safety, and cost optimization

• Design and deploy enterprise-grade AI agents and copilots with robust monitoring and guardrails

• Establish LLM observability: token usage tracking, latency monitoring, prompt/response logging, and cost attribution

Operational Excellence

• Own uptime, reliability, and performance of ML/LLM services (SLIs/SLOs)

• Implement comprehensive monitoring, alerting, and incident response for ML systems

• Participate in on-call rotations and drive post-incident reviews to improve system resilience

• Build automation and tooling to reduce toil and accelerate ML development velocity

Collaboration & Leadership:

• Partner with ML Engineers and Data Scientists to translate research into production-ready systems

• Collaborate with platform and infrastructure teams on cloud architecture and resource optimization

• Mentor team members on MLOps best practices, production ML patterns, and operational excellence

• Drive technical decisions on tooling, frameworks, and architectural patterns

Required Qualifications and Skills:

• Education: B.S./M.S./Ph.D. in Computer Science, Engineering, or related technical field

• Experience: 4+ years of software engineering experience with 2+ years focused on MLOps/LLMOps

• MLOps Expertise:

• Production experience with ML model serving frameworks (e.g., Tensor Flow Serving, Torch Serve, Triton)

• Hands-on with ML experiment tracking and model registry tools (MLflow, Weights & Biases, Kubeflow)

• Proficiency in workflow orchestration (Airflow, Prefect, Kubeflow Pipelines, Metaflow)

• LLMOps Expertise:

• Experience with LLM deployment, fine-tuning, and evaluation frameworks (e.g., vLLM, Lang Chain, Llama Index)

• Knowledge of prompt engineering, RAG architectures, and LLM application patterns

• Familiarity with LLM observability tools (e.g., Lang Smith, Arize, Why Labs)

Cloud & Infrastructure:

• Strong experience with major cloud providers (AWS, GCP, or Azure) and ML-specific services (Sage Maker, Vertex AI, Azure ML, Bedrock)

• Proficiency in containerization (Docker, Kubernetes) and infrastructure-as-code (Terraform, CloudFormation, Pulumi)

• Experience with microservices architecture and API development (REST, gRPC)

• Software Engineering:

• Strong programming skills in Python, terraform and Helm; familiarity with Go, Java, or Rust is a plus

• Deep understanding of CI/CD practices and tools (GitHub Actions, GitLab CI, Jenkins, ArgoCD)

• Experience with monitoring and observability stacks (Prometheus, Grafana, Data Dog, ELK)

• Operational Excellence:

• Track record of managing production systems with defined SLIs/SLOs

• Experience with on-call rotations, incident management, and reliability engineering practices

Desired Qualifications and Skills:

• Experience building internal ML platforms or developer tooling used by multiple teams

• Hands-on with distributed training frameworks (Ray, Horovod, Deep Speed)

• Knowledge of model optimization techniques (quantization, distillation, pruning)

• Familiarity with feature stores (Feast, Tecton) and data versioning tools (DVC, LakeFS)

• Understanding of ML security best practices, model governance, and compliance requirements

• Experience with cost optimization and resource management for large-scale ML workloads

• Contributions to open-source MLOps/LLMOps projects

• Background in applied ML or data science with practical model development experience
