Sr. Machine Learning Engineer, Network Engineering

We are seeking a highly skilled Senior Software Engineer to lead development of a platform that combines large scale LLM training with advanced network data processing and intelligent diagnostic capabilities.

This role requires strong machine-learning engineering skills, deep software engineering fundamentals, and a solid understanding of network systems.

• Design, build, and maintain pipelines for LLM pretraining, supervised fine-tuning (SFT), reward modeling, PPO/RLHF, and model evaluation
• Develop scalable backend services and distributed training infrastructure
• Build data-ingestion and transformation pipelines for networking datasets including device inventory, topology data, ARP/MAC tables, routing state, metrics, telemetry, and logs
• Normalize and model heterogeneous networking data to support ML workflows and agent inference
• Develop intelligent agent capabilities, including intent classification, context tracking, troubleshooting logic, and action-routing workflows
• Collaborate with networking domain experts to translate operational needs into model and platform capabilities
• Implement CI/CD, model versioning, orchestration, and production-grade deployment pipelines
• Drive architectural decisions to ensure scalability, modularity, reliability, and performance

• 5+ years of experience in applied ML, ML systems, or backend platform engineering
• Strong experience with LLM training, including SFT, LoRA/PEFT, RLHF, reward modeling, and PPO
• Proficiency with PyTorch and distributed training technologies
• Solid backend engineering skills in Python, including APIs, microservices, data modeling, and containerization
• Strong understanding of networking fundamentals such as IP addressing, Ethernet, VLANs, routing protocols (BGP/OSPF/ISIS), and topology concepts
• Experience working with networking telemetry or operational data (SNMP, flow data, metrics, logs, routing/forwarding tables)
• Ability to interpret and model complex network states, device relationships, and diagnostic patterns
