About this role

Fireworks AI is hiring an AI Product Engineer - Nexus in San Mateo for a full-time engineering position. This role is ideal for a product-minded developer with strong full-stack expertise who wants to build innovative enterprise AI platforms.

Role Overview

The AI Product Engineer - Nexus position involves building and maintaining Fireworks Nexus, a platform that helps engineering organizations route AI workloads from expensive proprietary models to open-source alternatives. Operating out of the San Mateo office, this high-autonomy individual contributor role requires end-to-end ownership of product features, from design to production deployment, enabling dramatic reductions in artificial intelligence spending without sacrificing quality.

Key Responsibilities

Own product features end-to-end across Nexus and the broader Fireworks platform, covering intelligent routing, FireConnect harness integrations, cost observability, and enterprise controls.
Build routing and migration layers that evaluate request difficulty in real-time, directing routine work to open models while routing complex tasks appropriately.
Simplify adoption by extending FireConnect and compatible APIs so teams can integrate Nexus into existing tools using a base URL and model ID.
Develop across the full stack utilizing React, TypeScript, Python, and Go to deliver polished production surfaces for technical users.
Adapt to fast-evolving product needs including new models, serving paths, consumption models, and multi-agent harness tooling.
Partner with Infrastructure, Applied Research, Growth, Data, and Design teams to translate platform capabilities into developer-friendly products.
Instrument built features to analyze user friction points and iteratively remove them.

Requirements

Three or more years of professional experience as a software engineer with a focus on building and shipping user-facing products.
Strong full-stack proficiency, including comfort with React, TypeScript, and backend languages like Python or Go, alongside APIs and databases.
Proven track record of delivering developer-facing products such as APIs, dashboards, consoles, CLIs, or developer tools.
Demonstrated end-to-end ownership from defining ambiguous problems to deploying solutions.
Strong product instincts centered on optimizing developer experience.
Ability to operate at high velocity with extreme ownership, making pragmatic trade-offs to ship rapidly.

Nice to Have

Experience building products on top of complex infrastructure, inference platforms, cloud services, data platforms, or machine learning tooling.
Background in building for deeply technical users where the product surface includes APIs as well as user interfaces.
Comfort working in a fast-moving, founder-led environment characterized by weekly product evolutions.
Daily usage of AI tools with a sharp intuition for exceptional AI developer experiences.
