Fireworks AI; United States; On-site; USD 150,000 - 210,000; Full time

Job summary

Fireworks AI is building a high-autonomy product engineering team to fuel a new PLG growth track. As one of the first engineers, you’ll shape the developer journey from discovery through first API call to long-term expansion.

You’ll diagnose problems, ideate solutions, and run experiments to prove what works best for developers. The role demands strong full‑stack capabilities, solid experience with A/B testing and product analytics, and a bias toward action.

Qualifications

• 5+ years building and shipping user-facing products, including real time on product or growth surfaces as a senior, staff, or founding engineer.

• Experience with consumption or usage-based pricing and billing.
• Excellent written and verbal communication with engineers and non-engineers.

Responsibilities

• Own developer outcomes end to end: identify problems, shape solutions, prototype, ship to production, instrument, and learn from results.
• Build growth foundations: event tracking, funnels, experimentation framework, lifecycle messaging.
• Talk to developers directly to observe first-hand where the first call fails and translate that into working code.
• Craft polished, fast, accessible experiences on marketing site and product, and collaborate with product, design, marketing, data, and sales to enable self-serve growth alongside sales-led motion.
