AI Field Engineer - Strategic Partnerships

About Us:

Fireworks is the platform for specialized intelligence, enabling companies to build, train, and serve AI models tailored to their own data, workflows, and products. Founded by the team behind PyTorch and backed by AMD, Atreides, Benchmark Capital, Index Ventures, Lightspeed, NVIDIA, Sequoia Capital, and TCV, Fireworks powers production AI with hundreds of state-of-the-art open models across text, image, embedding, audio, and multimodal workloads. Today, Fireworks is a Series D company valued at $17.5 billion, bringing together an ambitious, collaborative team that's building the future of enterprise AI.

In the last few months alone we launched Fireworks Training, partnered with Microsoft Azure Foundry, and published research straight from our production systems. A few examples of what that looks like in practice:

Frontier RL is cheaper than the mega-cluster narrative suggests: we ran cross-region rollouts using 98% sparse weight deltas and published what we learned. ( blog )

Open source agents with frontier advisors: matching frontier performance through training and harness engineering. ( blog )

The fine-tuning bottleneck is not the algorithm: integration friction and iteration speed are what actually stall teams; we documented the patterns across dozens of customer engagements. ( blog)

The Role

As an AI Field Engineer for Strategic Partnerships, you will be one of the technical owners of Fireworks' most strategic partnership. You’ll work closely with Strategic Partner field teams, Partner-aligned ISVs, and the SIs that run enterprise AI transformation programs to make Fireworks the default inference and fine-tuning layer in every Partner AI architecture. The role sits at the intersection of engineering, partner development, and customer delivery. You build reference architectures, run benchmarks, debug production integrations, and co-develop POCs — all while holding your own in executive-level conversations about strategy, roadmap, and business outcomes.

You spend most of your time building and enabling. You ship code, run joint POCs with Partner field teams, and architect deployments that span Strategic Partners and Fireworks. But you also lead discovery conversations, align partner stakeholders, and translate field signals into product improvements that compress the feedback loop from partner to roadmap.

The Segment

As a Field Engineer aligned with our Partnerships team you own the technical relationship between Fireworks and the Partner ecosystems, Partner field teams, ISVs building on Strategic Partners, and the SIs that deliver AI transformation programs on Strategic Partners. As an example, the Microsoft partnership is a core go-to-market bet: clients like UIPath, Stack Blitz, Motif run via Fireworks on Foundry.. Your job is to scale that pattern across the partner ecosystem. These engagements involve large, multi-stakeholder organizations, so you will need to navigate both the enterprise buyer (IT, security, compliance) and the builder (ML engineers, platform teams, app developers), while building the trusted-advisor relationships inside Microsoft's field that multiply your reach.

What You'll Work On

Technical Delivery and Deployment

Be the technical lead on co-sell motions with Strategic Partners — joint reference architectures, partner integration patterns, and shared POCs for strategic accounts.

Build end-to-end POCs and MVPs alongside partner engineering teams, working inside their codebases, infrastructure, and constraints.

Run load tests and establish latency, throughput, and cost baselines against realistic customer traffic profiles, and tune deployments to hit those targets.

Deploy and validate new model families on inference frameworks (vLLM, SGLang), determining optimal shapes, quantization configs, and serving patterns across workloads.

Model Strategy and Fine-Tuning

Guide customers on model selection, fine-tuning strategy (SFT, DPO, RFT), and evaluation methodology.

Build and run fine-tuning pipelines directly with customers, navigating trade-offs between model families, compute cost, and quality targets.

Design and implement evaluation frameworks that measure production-quality metrics, not just benchmark scores

Product Feedback and Platform Improvement

Own the feedback loop — surface partner-driven product gaps to Fireworks engineering, and translate the roadmap back into partner messaging.

Ship external technical content: reference architectures, integration guides, and benchmark posts that make it easy for partners to win deals with us.
