About this role
AI Field Engineer (Enterprise) with 3+ years of experience to embed with Fireworks AI's most ambitious enterprise customers and turn complex GenAI challenges into production systems, fast. The technical tip of the spear, pairing deep hands-on engineering with executive presence to drive deals from first discovery call to production deployment.
What will you be doing?
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-keyboard inside customer environments, navigating their infrastructure, security requirements, and organizational constraints
Guide customers on model selection, fine-tuning strategy (SFT, DPO, RFT), and evaluation frameworks, moving them from open-model exploration to production at scale
Manage multi-stakeholder enterprise relationships: identify technical champions, navigate org politics, and align the right people to move deals forward quickly
Feed recurring customer pain points and deployment patterns back into the product roadmap
Team
Field engineering team led by Roberto Barroso Luque (ex-BCG X); flat, low-ego, extreme ownership; no seniority title distinctions; arrogance screened out; client-facing by week 1-2; engineers push PRs to the Fireworks codebase.
Tech stack
Python, vLLM, SGLang, TensorRT-LLM, Kubernetes, AWS, Azure, GCP, Azure AI Foundry, AWS Bedrock, AWS SageMaker, GCP Vertex AI, LLM Fine-Tuning (SFT, DPO, RFT), GPU Infrastructure
About Fireworks AI
Fastest way to build, tune and scale AI on open models; high-performance GenAI inference platform powering Uber, DoorDash, Notion, Cursor. Founded by Meta PyTorch and Google Vertex AI veterans. 211 employees, founded 2021, $1.5B total funding.
Deep hands-on experience with LLM inference and/or training; working knowledge of open-model frameworks (vLLM, SGLang, TensorRT-LLM) and fine-tuning (SFT minimum; DPO/RFT a strong plus). Closed-model/API-wrapper-only experience will not clear the bar
Proven ability to ship production code inside a customer's environment (built and deployed POCs/MVPs in someone else's prod), not just advisory work
Strong Python plus GPU/cloud infrastructure (AWS, Azure, or GCP) and comfort with Kubernetes
Executive presence and enterprise navigation: deep-dive with an ML engineer and present trade-offs to a VP the same day
Pre-sales or customer-facing field engineering experience (FDE, Applied AI Engineer, Solutions Architect, or similar); pure SWEs without customer-facing exposure are not a fit
3+ years in client-facing AI/ML roles
