The Team

The Developer AI team is on a mission to boost the productivity, creativity, and satisfaction of our engineering teams by embedding AI capabilities into our internal developer tools and workflows. We build smart assistants, automation systems, and intelligent insights that redefine what’s possible in the software development lifecycle.

The Role

At the JET platform engineering department we are looking for someone who can help us create an exceptional developer experience and take our developer platform to the next level. You should be able to swim fast, adapt, and stay up to date with the latest technology; and you should be someone who gets things done.

As a Staff Engineer, you’ll lead technical strategy and architecture across key platform initiatives, with a focus on AI-powered developer solutions and tooling. You’ll partner with engineering leadership, guide technical execution, and mentor engineers—while staying hands-on and close to the code.

• Design, build, and maintain scalable AI-powered developer tools and services
• Lead the architecture for LLM integration, prompt frameworks, and vector-based search systems
• Collaborate with product managers, UX designers, and other engineers to define technical solutions
• Champion engineering excellence, setting patterns, reviewing critical code, and enabling high-velocity teams
• Integrate LLMs (like OpenAI, Claude, or open-source alternatives) into developer workflows
• Experience building Agentic AI solutions in production environments
• Experiment with prompt engineering, embeddings, vector search, and fine-tuning techniques
• Drive initiatives to improve developer velocity, quality, and satisfaction
• Act as a multiplier: mentor, unblock, and elevate others across engineering
• Stay current with advances in AI, developer tooling, and software engineering best practices

What will you bring to the table?

• Deep Experience in software engineering, with a track record of leading high-impact projects
• Proficiency in languages like Python, C#, or Java
• Experience with AWS and containerized applications (Docker, Kubernetes)
• Expert with REST/gRPC APIs and event-driven systems
• Excellent system design skills and experience architecting complex distributed systems
• Exposure to LLM APIs, vector databases, and basic ML concepts
• Experience with building Agentic AI solutions
• Strong communication and collaboration skills
• Passion for developer experience and building tools that engineers love
• Proven experience mentoring engineers and influencing beyond your immediate team

Nice-to-Haves

• Hands-on experience with OpenAI, Hugging Face, LangChain, or similar frameworks
• Background in AWS AI ecosystem and tools like Bedrock
• Experience with GitHub Copilot or similar
• Contributions to open-source developer tools or AI projects
