Job Description

Python Software Engineer - AI Workflows

About the Role

What if your Python expertise could directly shape the infrastructure behind next-generation AI? We're looking for a senior full-stack Python engineer to build the data pipelines, annotation tooling, and evaluation systems that leading AI labs depend on to train and improve their models.

This is a fully remote, flexible contract role for an experienced engineer who wants to work on real production systems at the cutting edge of AI - not toy projects, but high-impact infrastructure that influences how the world's most advanced models are built.
  • Organization
    : Alignerr
  • Type
    : Hourly Contract
  • Location
    : Remote
  • Commitment
    : 20-40 hours/week
What You'll Do
  • Design, build, and optimize high-performance Python systems supporting AI data pipelines and evaluation workflows
  • Develop full-stack tooling and backend services for large-scale data annotation, validation, and quality control
  • Improve reliability, performance, and safety across existing Python codebases
  • Collaborate with data, research, and engineering teams to support model training and evaluation workflows
  • Identify bottlenecks and edge cases in data and system behavior, then implement scalable fixes
  • Participate in synchronous design reviews to iterate on architecture and implementation decisions
Who You Are
  • 3-5+ years of professional experience writing production-grade Python
  • Strong full-stack developer with a solid systems programming background
  • You write clean, maintainable code - linters, formatters, and testing frameworks are second nature
  • Experienced in integrating AI services and APIs, handling edge cases, and building robust error reporting
  • A clear communicator - both in writing and in synchronous discussions
  • Native or fluent English speaker
  • Available to commit 20-40 hours per week
Nice to Have
  • Prior experience with data annotation, data quality, or evaluation systems
  • Familiarity with AI/ML workflows, model training, or benchmarking pipelines
  • Experience with distributed systems or developer tooling
Why Join Us
  • Work on cutting-edge AI infrastructure alongside leading research labs
  • Fully remote and flexible - work when and where it suits you
  • Freelance autonomy with the structure of meaningful, high-impact engineering work
  • Tackle real production challenges that directly shape how next-generation AI models are built
  • Potential for ongoing work and contract extension as new projects launch
