Job description

Write the Next Great Story in AI + Aviation

Some companies chase the future. At Goodwin, we’re building it from scratch, at breakneck speed, in one of the most dynamic, unclaimed frontiers:charter aviation.
We don’t just want another engineer; we want a co-author of our story—someone who’ll look back and say, I helped reinvent how an industry works.

What’s in it for you?

• Autonomy: You won’t just “build features”—you’ll shape vision, architecture, and product from day one.
• Legacy: See your work in the real world, changing how people move and connect.
• Story: Join a chapter that hasn’t been written. Become known for building something that lasts.
• Speed: No red tape. Ideas move from sketch to production in weeks, not quarters.

The Role:

As our Principal AI Engineer, you’ll own, build, and launch next-generation agentic AI products. You’ll lead the charge in designing, fine-tuning, and deploying advanced LLMs (OpenAI, Anthropic, open-source), create groundbreaking search and recommendation engines, and architect robust AI infrastructure, making complex problems simple, intuitive, and transformative.

You’ll Own:

• End-to-end delivery of AI products: dream it, build it, launch it, scale it.
• Building, fine-tuning, and customizing LLMs for real-time conversational AI, deep search, and world-class recommendations.
• Creating scalable infrastructure—vector databases, embeddings, RAG pipelines—so every answer is smarter than the last.
• Delivering tangible, visible impact in an industry hungry for change.

You, at Your Best:

• You’ve shipped high-impact AI products—hands-on, not just in theory.
• You’ve fine-tuned, deployed, and optimized LLMs (GPT, Claude, or open-source) in production.
• You’re fluent in modern AI stacks: semantic search, vector DBs, advanced cloud, MLOps, Python, and more.
• You anticipate trends, invent new approaches, and bring relentless curiosity and grit.
• You want to help write the playbook—not just follow one.

Bonus Points:

• Startup DNA or time at a world-class engineering org.
• Real-time, large-scale recommendation or analytics experience.
