Job Summary

Customer is one of the world’s fastest-growing AI companies accelerating the advancement and deployment of powerful AI systems.

They help customers in two ways: Working with the world’s leading AI labs to advance frontier model capabilities in thinking, reasoning, coding, agentic behavior, multimodality, multilinguality, STEM and frontier knowledge; and leveraging that work to build real-world AI systems that solve mission-critical priorities for companies.

We’re looking for a world-class Python Developer — someone who lives and breathes code, optimizes for performance, and has proven mastery on competitive programming or data challenge platforms like LeetCode, Codeforces, HackerRank, or Kaggle.

This is a pure coding role — where you’ll tackle challenging engineering problems, design scalable systems, and collaborate with leading AI research teams.

Job Responsibilities

· Build, test, and optimize high-performance Python systems used in large-scale AI and data pipelines.

· Design and maintain modular, clean, and production-ready Python codebases.

· Collaborate with cross-functional teams (data, infra, and research engineers) to deliver reliable backend components.

· Write efficient, maintainable, and testable code with strong focus on algorithms and data structures.

· Stay current with modern Python tools, frameworks, and best practices.

Essential Skills

Required Qualifications

· Bachelor’s or Master’s in Computer Science, Software Engineering, or a related field.

· 4+ years of professional experience writing Python in production environments.

· Expert-level proficiency in Python and core libraries (Pandas, NumPy, AsyncIO, FastAPI, or similar).

· Proven track record on coding platforms — e.g., top percentile or strong rating on LeetCode, Codeforces, HackerRank, or Kaggle competitions.

· Deep understanding of data structures, algorithms, and problem-solving at scale.

· Experience with system design, clean architecture, and performance optimization.

· Working level Proficiency in ML/DS

Preferred Qualifications

· Strong experience with distributed systems, APIs, or data processing pipelines.

· Familiarity with cloud environments (AWS, GCP, or Azure) and CI/CD workflows.

· Experience in open-source contributions or building developer tools.

· Comfort working in fast-paced, research-driven environments.

Bonus

· Recognized performance in Kaggle, Codeforces, or ICPC/TopCoder contests.

· Deep curiosity for performance tuning, scalability, and elegant code design.

Other Details

· Work fully remotely, from anywhere.

· Collaborate with world-class AI labs and frontier research companies.

· Tackle real engineering challenges with high autonomy and ownership.

Commitment: Minimum 20 hours/week with 4-hour PST overlap (options: 20, 30, or 40 hrs/week).

Type: Contractor (no medical/paid leave).

Duration: 2 months (start date: immediately).
