AI Field Engineer (Enterprise)

Medilinkers, in partnership with AI Talent Hunt, is conducting a confidential search on behalf of a rapidly growing AI infrastructure company.

Medilinkers, in partnership with AI Talent Hunt, is looking for an AI Field Engineer (Enterprise) with 3+ years of experience to embed with some of the most ambitious enterprise customers and turn complex GenAI challenges into production systems — fast. You'll combine deep hands-on engineering expertise with strong customer-facing skills to drive technical evaluations, proof-of-concepts, and production deployments across enterprise environments.

• Lead technical discovery calls, scope POCs, and run load tests and evaluations to validate the right model architecture and deployment configuration for each enterprise customer.
• Build end-to-end POCs and production integrations hands-on within customer environments, navigating infrastructure, security requirements, and organizational constraints.
• Guide customers on model selection, fine-tuning strategies (SFT, DPO, RFT), and evaluation frameworks, helping them move from experimentation to production-scale deployments.
• Manage multi-stakeholder enterprise relationships, identify technical champions, navigate organizational dynamics, and align stakeholders to accelerate successful outcomes.
• Provide feedback on recurring customer pain points and deployment patterns, serving as a bridge between customers and engineering teams.

• Deep hands-on experience with LLM inference and/or training, including open-model frameworks such as vLLM, SGLang, and TensorRT-LLM.
• Experience with fine-tuning workflows (SFT required; DPO/RFT strongly preferred).
• Proven track record of building and deploying production solutions within customer environments.
• Strong Python programming skills and experience with cloud platforms (AWS, Azure, or GCP).
• Comfortable working with Kubernetes and GPU-based infrastructure.
