FDE does not replace our Solutions Architects. You will work alongside them as the deep-domain specialist in post-training, guiding customers through data strategy, algorithm selection, experiment design, and evaluation, and sizing the compute behind it. You’ll make sure we can deliver on our post-training POCs, drive adoption of our fine-tuning and RL platform, and turn customer goals into measurable gains in model quality. Your work directly affects customer success, company growth, and the hardening of our core platform. ## Responsibilities - Data Strategy: Help customers define and execute their data strategy for model post-training,  diagnose data quality issues that limit model performance outcomes, and provide recommendations for data generation for post-training scale - Algorithm Selection: Recommend the right post-training approach for each use case - Experiment Design & Hyperparameter Tuning: Design well-controlled experiments and tracking methods; diagnose training instabilities, reward hacking, and regressions. - Evaluation: Build evaluation frameworks with customers, including task-specific benchmarks, LLM-as-judge pipelines, and held-out test sets. Make sure gains are reproducibly aligned with production success metrics. - Model Selection: Guide base model selection methodology ahead of post-training efforts and baseline quality evaluations to guide post-training objectives. Interest in self-directed research of newly released open source models, particularly as they relate to post-training. - RL Workload Sizing: Scope and size RL and fine-tuning workloads, partner with sales and capacity teams to shape deals and capacity forecasts. - Strategic Customer Alignment: Serve as the primary post-training technical point of contact for aligned strategic accounts. Lead technical execution from scoping to production and make sure we hit critical milestones. - Product & Research Feedback Loop: Shape our fine-tuning and RL product roadmap with insights from the field. Contribute code, recipes, and reference implementations where needed, and drive early adoption of new features and research with strategic logos. ## Requirements - Experience: 5+ years in a technical role in ML engineering, Applied AI, Forward Deployed Engineering, or Solutions Architect, with recent hands-on experience post-training LLMs. - Post-Training Depth: Expert-level, hands-on experience with fine-tuning and/or  RL for LLMs, including SFT, LoRA, DPO, and RL (GRPO, PPO, etc).. - Experimental Rigor: Strong track record designing experiments, running ablations, and building evaluations that separate real improvement from noise. - Data Intuition: Proven ability to build and iterate on training datasets - Model Landscape Awareness: Broad knowledge of state-of-the-art open-source models and strong judgment on which base model to post-train for a given customer requirements - Coding Proficiency: Strong Python skills; comfortable working in production environments. - Experience leading complex, customer-facing technical projects, with exceptional project management and communication skills. Able to work in a highly X-functional environment. ## About Together AI Together AI, the AI Native Cloud, is purpose-built for AI engineers.
