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.
The Role:
As a Member of Technical Staff on the EMEA field team, you build on top of one of the largest inference platforms in the world. The work spans the stack: capabilities on top of inference and serving, tooling around fine-tuning and post-training of LLMs, and the product our region’s customers need that the core platform team will not take on. You are first and foremost an excellent software engineer; that is what we are testing for. You prefer building product to being customer-facing, and that is exactly right for this role, though you are welcome to join customer work when it interests you.
Treat this as a flexible role: a bucket for exceptional builders at different levels of experience rather than a fixed job spec. There is no specific seniority requirement; anywhere from 3 to 10 years of experience can fit.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we value most is first principles thinking: reasoning about unfamiliar problems from the ground up rather than from playbooks. You will be evaluated on this directly in the interview process, and strength here can outweigh gaps elsewhere in your background.
Key Responsibilities:
- Build: Design and ship product capabilities end to end, from ambiguous need to running in production.
- Build on Inference: Create capabilities on top of the serving stack: routing, model controls, observability, and whatever a deployment turns out to need.
- Build on Training: Ship tooling around fine-tuning and post-training of LLMs, from data pipelines to evaluation, working alongside our applied ML engineers.
- Own Regional Capability: Turn EMEA-specific requirements into product, working with core platform where the line is unclear.
- Engineering Quality: Set the engineering bar for the regional team; your code is the reference.
- Agentic Development: Use coding agents and AI tooling as a core part of how you build, with judgment about when to trust the output.
- Optional Customer Work: Join deployments or customer conversations when useful or interesting; never required.
Minimum Qualifications:
- First principles and critical thinking: The ability to break down novel problems and reason to a solution without a reference implementation. This is the primary interview signal and can outweigh other qualifications.
- Excellent software engineering: Depth in backend systems and infrastructure, and a track record of shipping production systems you owned.
- Strong coding skills in Python and at least one systems language.
- Fluent in AI-assisted and agentic engineering: Uses coding agents and AI tooling as a core part of how you build, and knows when to trust the output and when not to.
- Genuine interest in inference and AI infrastructure.
