Forward Deployed Engineer (inference & Post-training) - Mandarin Speaking

Together AI Together AI · Data AI · San Francisco, CA · Customer Success

Forward Deployed Engineer (FDE) focused on Inference & Post-Training for strategic customers. Responsibilities include optimizing inference engines, tuning performance for POCs and deployments, and guiding customers through fine-tuning pipelines (LoRA, SFT, DPO, RLHF, GRPO). Acts as a technical point of contact for strategic accounts, ensuring successful platform adoption and influencing product roadmap.

What you'd actually do

  1. Inference Engine Optimization: Select, configure, and optimize inference engine based on hardware, model architecture, and workload profile
  2. Configuration & Performance Tuning: Develop configuration updates to win critical POCs, benchmarks, and optimize customer deployments; tune KV cache, apply speculative decoding, determine optimal tensor parallelism, and determine quantization strategy to hit throughput and latency targets.
  3. Post-Training & Fine-Tuning: Drive hands-on RL training runs and optimize system design; guide customers through LoRA, SFT, DPO, RLHF, and GRPO pipelines from experimentation through production.
  4. Strategic Customer Alignment: Act as the primary technical point of contact for aligned strategic accounts — monitoring and optimizing endpoint configurations, helping customers get the most out of the platform, and collaborating to ensure we hit critical milestones.
  5. Opinionated Onboarding: Establish direct alignment with strategic customers at onboarding; ensure the right inference and post-training configurations are in place from day one to improve time-to-value.
