Solutions Architect

In the last few months alone we've launched the Fireworks Training Platform, partnered with Microsoft Azure Foundry, and published research straight from our production systems which is helping scale some of the most innovative companies and products of our generation.

As an SA you'll be close to all of it. The customer conversations you lead directly feed our roadmap, and the work you do shows up in what we build and publish next. 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
• Training-inference parity in MoE models — kernel fusions that are mathematically equivalent can still drift numerically; we shipped the fixes across Kimi K2.5 and Qwen3.5-MoE
• The fine-tuning bottleneck isn't the algorithm — integration friction and iteration speed are what actually stall teams; we documented the patterns across dozens of customer engagements

If you want to work on hard infrastructure problems, be close to the customers pushing the frontier, and actually see your work ship come work with us!

The Role:

Solutions Architects at Fireworks are the technical and strategic owners of the customer relationship from the first discovery call through to production. You'll work with some of the most ambitious engineering teams in the world, translating complex business problems into concrete AI solutions built on the Fireworks platform.

This is a role that demands both technical depth and strong people skills. You'll need to earn the trust of ML engineers and VPs in the same meeting, scope and execute POCs without losing sight of the customer's definition of success, and know enough about inference, fine-tuning, and model architecture to make credible recommendations under pressure.

We hire SAs across two tracks. Both require strong technical grounding and sharp customer instincts; the difference is where each track places its emphasis.

Enterprise SA Track

• Works with digital native and large organizations — navigating multiple stakeholders, procurement cycles, and executive relationships
• Heavy emphasis on executive presence: equally comfortable presenting to a CTO and debugging a latency issue with an ML engineer
• Leads complex technical sales: discovery, solution design, POC execution, commercial negotiation
• Owns the account relationship end-to-end, including expansion and renewal
• Strong commercial instincts understands how to build a business case and close large deals

Applied AI Track

• Works with high-velocity accounts and technology partners startups, ISVs, and hyperscaler ecosystems
• Heavier emphasis on technical execution more time in the code, building integrations, running enablements
• Faster iteration cycles with less org navigation focused on shipping working solutions quickly
• Embeds with partner engineering teams to enable their AI practices and build joint solutions
• Comfortable operating across engineering, partnerships, and sales simultaneously

What You'll Work On:

Regardless of track, SAs at Fireworks own a consistent set of responsibilities:
