About The Role
  • What if your systems programming expertise could directly shape the infrastructure powering the world's most advanced AI models? We're looking for Senior C++ Engineers to design and build the high-performance data pipelines, annotation tooling, and evaluation systems that leading AI labs depend on to train and improve next-generation AI.
  • This is a fully remote, flexible contract role for engineers who write clean, fast, production-grade C++ and want to work on problems that genuinely matter.
  • Organization: Alignerr
  • Type: Hourly Contract
  • Location: Remote
  • Commitment: 20--40 hours/week
What You'll Do
  • Design, build, and optimize high-performance C++ systems supporting large-scale AI data pipelines and evaluation workflows
  • Develop full-stack tooling and backend services for data annotation, validation, and quality control
  • Improve reliability, performance, and memory safety across existing production C++ codebases
  • Identify bottlenecks and edge cases in system and data behavior --- then implement scalable, production-ready fixes
  • Collaborate with data, research, and engineering teams to accelerate model training and evaluation
  • Participate in synchronous design reviews to iterate on architecture and implementation decisions
Who You Are
  • Full-stack developer with a strong systems programming background
  • 3--5+ years of professional experience writing production C++, with a focus on modern standards (C++17 or C++20)
  • Deep familiarity with performance optimization, concurrency (threading, atomics), and memory safety (RAII, smart pointers, sanitizers)
  • Native or fluent English speaker with clear written and verbal communication skills
  • Able to commit 20--40 hours per week with professional reliability
  • Self-directed and effective when working independently in a remote environment
Nice to Have
  • Prior experience with data annotation, data quality systems, or evaluation pipelines
  • Familiarity with AI/ML workflows, model training, or benchmarking infrastructure
  • Experience with distributed systems or developer tooling
  • Exposure to working with research teams or in fast-moving technical environments
Why Join Us
  • Work directly with leading AI labs on production systems that power cutting-edge research
  • Fully remote and flexible --- work when and where you're most productive
  • Freelance autonomy with the substance of meaningful, high-impact engineering work
  • Tackle genuinely hard technical problems with real consequences for AI development
  • Potential for ongoing work and contract extension as new projects launch
Responsibilities
  • Engineering and Information Technology
