Job description

Software Engineer – Python (Advanced)

About The Role

What if your Python expertise could directly influence how AI systems are built, evaluated, and improved for millions of people? We're looking for advanced Python engineers to work on real-world engineering and data challenges — designing production-grade solutions, analyzing complex datasets, and helping shape the quality of AI-driven applications.

This is a fully remote, flexible contract role built for senior engineers who thrive on autonomy, love solving ambiguous problems, and take pride in clean, performant code.

• 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 real-world datasets to support engineering and modeling workflows
• Write and optimize complex SQL queries to extract, transform, and validate data
• Review, debug, and improve existing codebases for performance, reliability, and maintainability
• Translate ambiguous, high-level requirements into concrete, well-reasoned technical solutions
• Apply consulting-style problem solving to evaluate tradeoffs and recommend best-fit approaches
• Document assumptions, decisions, and implementation details with clarity and precision
• Evaluate AI-generated code and analytical outputs for correctness and quality

Must-Have

• 4+ years of professional software engineering experience
• Advanced Python proficiency — clean architecture, performance optimization, and debugging at depth
• Strong data analysis experience working with real-world, production datasets
• Solid SQL skills including complex queries, joins, and data validation
• Prior consulting or client-facing experience, with the ability to reason through open-ended problems independently

Nice to Have

• Experience working with large, messy, or poorly documented datasets
• Familiarity with backend systems, REST APIs, or data pipelines
• Comfort evaluating or auditing AI-generated code and outputs
• Strong written communication and meticulous 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 engineering work
• Make a direct, tangible impact on how AI systems reason about and produce code
• Potential for ongoing work and contract extension as new projects launch
