Job description

Senior C# Full-Stack Engineer - AI Data & Infrastructure
About the Role
What if your C# expertise could directly shape the infrastructure powering next-generation AI? We're looking for a Senior C# Full-Stack Engineer to build and optimize the systems that leading AI labs depend on - from data pipelines and annotation tooling to evaluation infrastructure that influences how frontier models are trained and assessed.
This is a fully remote contract role with meaningful technical challenges, real production impact, and the flexibility to work on your own terms.
  • 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 at scale
  • Improve reliability, performance, and safety across existing C# 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, production-ready fixes
  • Participate in synchronous design reviews to iterate on architecture and implementation decisions
Who You Are
  • Native or fluent English speaker with strong written and verbal communication skills
  • Experienced full-stack developer with a solid systems programming foundation
  • 3-5+ years of professional experience writing production C# code, with command of modern standards
  • Deep understanding of performance optimization, concurrency (threading, atomics), and memory safety (RAII, smart pointers, sanitizers)
  • Able to commit 20-40 hours per week with reliability and consistency
  • Self-directed and comfortable working in fast-moving, async-first environments
Nice to Have
  • Prior experience with data annotation pipelines, data quality systems, or evaluation infrastructure
  • Familiarity with AI/ML workflows, model training loops, or benchmarking pipelines
  • Experience building distributed systems or developer tooling at scale
Why Join Us
  • Work directly with leading AI labs on systems that influence how frontier models are built
  • Tackle genuinely hard engineering problems - not maintenance tickets
  • Fully remote and flexible - structure your week around your best work
  • Freelance autonomy with the substance of high-impact engineering work
  • Potential for ongoing contracts and expanded scope as projects grow
