• Integrate AI capabilities into existing products and services through APIs and microservices.
• Design and implement evaluation frameworks to assess model accuracy, reliability, and task-specific performance.
• Monitor production performance and implement optimizations based on evaluation metrics and real-world usage patterns.
• Stay up-to-date with the rapid changes in the AI landscape (e.g., new foundation models, quantization techniques) and prototype new ideas quickly.

About you:

• Proficiency developing clean modular and efficient code with Python

• Ability to balance innovation with practical business requirements
• Adaptable when navigating ambiguity and rapidly shifting priorities
• Comfortable communicating technical concepts and trade-offs to non-technical stakeholders

Bonus Points:

• Bachelor's degree in Computer Science, Machine Learning, Mathematics, Statistics, Data Science, or quantitative field OR equivalent hands-on experience in a related professional industry

How we work:

• We believe in starting simple, soon — progress over perfection. We value architectural clarity and execution speed. You'll be joining a small, ambitious team committed to high trust, low ego collaboration. It's a dynamic environment where teams embrace ambiguity, adapt quickly to change, and move fast to seize opportunity.
