[Remote] Senior AI Engineer

Note: The job is a remote job and is open to candidates in USA. Paper is reimagining how schools support students so that every learner can reach their full potential. We are seeking a Senior AI Engineer to architect and operationalize multimodal AI systems at production scale, owning end-to-end AI initiatives that power features used by millions of learners.

Responsibilities

• Design and deploy real-time voice and vision AI systems for classroom environments
• Evaluate tradeoffs between fine-tuning, RAG pipelines, prompt-based approaches, and tool-using agents
• Build scalable inference systems with strict latency and cost constraints
• Fine-tune and evaluate LLMs, ASR models, and vision/multimodal architectures
• Design robust evaluation frameworks (offline + online)
• Implement safety guardrails and bias mitigation strategies
• Own the full ML lifecycle: data ingestion, training, validation, deployment, monitoring, and iteration
• Optimize infrastructure for GPU utilization, latency, and cost efficiency
• Partner with MLOps to build reliable, versioned AI pipelines
• Work closely with Product and Engineering to translate classroom needs into production-ready AI systems
• Clearly communicate tradeoffs between model complexity, performance, and cost
• Contribute to long-term AI roadmap and architecture decisions

Skills

• 5+ years building and deploying production AI/ML systems
• Hands-on experience operationalizing LLM-based systems (RAG, agents, prompt workflows, fine-tuning)
• Experience with multimodal or vision systems
• Demonstrated ownership of AI systems in production (monitoring, evaluation, iteration)
• Strong Python proficiency and experience with PyTorch or TensorFlow
• Experience working with distributed/cloud infrastructure for ML workloads
• Experience building real-time or low-latency ML systems
• Experience working with educational data or regulated environments (FERPA/COPPA)
• Experience designing evaluation frameworks for generative systems
• Background in optimizing ML systems for cost at scale

Benefits

• Comprehensive & competitive compensation, health benefits, retirement plan, stock options, and more.
• In addition to vacation days, we provide Paperites with sick days and 4 extra weeks off - including statutory holidays, Paper Days throughout the year, and a full Paper Week from Dec 25 to Jan 1.
