Software Engineer – Python (Advanced)

About The Role

What if your Python expertise could directly influence how the next generation of AI systems thinks, reasons, and writes code? We're looking for advanced Python engineers to work on real-world software and data challenges — building, evaluating, and improving the high-quality technical workflows that power cutting-edge AI applications.

This is a fully remote, flexible contract role for engineers who love solving hard problems and want their work to matter. If you thrive in ambiguous, high-stakes environments and write Python that other engineers actually want to read, this is for you.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

What You'll Do

• Design, implement, and optimize advanced Python code for production-level systems
• Analyze and manipulate structured datasets to support engineering and modeling workflows
• Write and optimize SQL queries to extract, transform, and validate data
• Review, debug, and improve existing codebases for performance, reliability, and maintainability
• Translate ambiguous or high-level requirements into concrete, well-reasoned technical solutions
• Evaluate tradeoffs and recommend best-fit approaches with a consulting mindset
• Document assumptions, decisions, and implementation details with clarity and precision
• Evaluate AI-generated code and analytical outputs for correctness and quality

Who You Are

Must-Have

• 4+ years of professional software engineering experience
• Advanced Python proficiency — you think about clean architecture, performance, and debugging instinctively
• Strong experience analyzing real-world datasets
• Solid SQL skills, including complex queries and data validation
• Prior consulting or client-facing experience — you're comfortable reasoning through open-ended problems and communicating your thinking clearly

Nice to Have

• Experience working with large, messy, or unstructured datasets
• Familiarity with backend systems, APIs, or data pipelines
• Comfort evaluating or critiquing AI-generated code and outputs
• Strong written communication skills with sharp attention to detail

Why Join Us

• Work on cutting-edge AI projects alongside leading research labs
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, task-based work
• Make a direct, tangible impact on how AI understands and generates software
• Potential for ongoing work and contract extension as new projects launch
