Python Software Engineer - AI Workflows
AlignerrFull 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
