- This team operates at the bleeding edge of AI, focusing on high-impact, moderately higher-risk projects that directly influence our end product. While your day-to-day work will heavily involve Language Models and Agentic AI, we expect you to be deeply versed in all of Machine Learning
- You will have the runway to dive deep into model architectures, debug complex algorithmic behaviors, fine-tune state-of-the-art models, and translate your findings into deployable product enhancements
- While our ultimate goal is delivering business value, we maintain a strong culture of scientific rigor. If an experiment yields novel, high-quality results, you will have the opportunity and support to publish your findings in top-tier AI conferences (e.g., NeurIPS, ICLR, ACL)
- Mid AI Research Engineer (2–3+ years of experience)
- Experiment & Build: Design, set up, and execute experiments focusing on LLMs, Agentic AI, model fine-tuning, and broader ML systems. Manage reproducible research pipelines, version code, and data, and select the right frameworks for prototyping
- Algorithmic Debugging:



Actively investigate why a model isn’t converging, why outputs are inconsistent, or why results are unreliable across different ML architectures
- Code Quality: Write clean, modular code (effective use of classes, functions, and documentation) following strict software engineering best practices
- Autonomous Delivery: Deliver projects with a high degree of autonomy. Present results clearly, explain the AI behind your findings, and align experiments with team priorities
- Senior AI Research Engineer (4+ years of experience)
- All of the above, plus:
- End-to-End Ownership & Strategy: Deliver clean, extendable research pipelines end-to-end. Set and drive the overall research strategy based on expected business leverage, identifying domain-wide opportunities
- Bridge Research & Product: Translate experimental findings and research breakthroughs into clear, actionable, and deployable directions
