This fully remote contract role is for a senior Python engineer who builds and optimizes the data pipelines, annotation tools and evaluation systems that AI labs use to train and benchmark their models. The work is hands-on with production systems and close collaboration with research and engineering teams. It suits backend engineers with deep Python and full-stack experience who want to lead technical decisions in AI infrastructure.
This fully remote freelance contract involves simulating attacks against web applications, internal and external networks, and cloud environments to find weaknesses before real adversaries do. It is aimed at experienced offensive security professionals who can manage engagements independently and explain their findings clearly to non-technical stakeholders. The role also includes recurring red-team and purple-team support alongside security operations teams.
This is a remote contract role for a senior Rust engineer who will design, optimize, and lead the backend systems behind AI data pipelines and model evaluation workflows. The work involves reliability, performance, and safety of production codebases, and suits experienced systems engineers who can also lead architecture discussions with research and engineering teams.
This contract role involves turning mathematical theorems, lemmas, and proofs from textbooks and articles into precise, machine-checked Lean 4 code. The work also includes checking existing formalizations for logical soundness and flagging gaps in informal arguments, with the output used to build datasets that teach AI systems to reason about mathematics. It suits mathematicians and formal verification experts who can work independently and on their own schedule.
This contract role involves turning rigorous informal mathematical proofs into machine-checkable Lean 4 formalizations and identifying gaps and hidden assumptions along the way. It is aimed at mathematicians with graduate-level training who enjoy precise proof writing and formal verification. The work is part-time and remote, with collaboration alongside AI researchers.
This remote hourly contract involves reviewing AI-generated legal analyses, policy summaries and government-related content for accuracy, completeness and proper use of legal reasoning. It is aimed at professionals with legal, policy or government knowledge who can judge whether AI responses handle nuance in legislation, case law, compliance and public policy.
This remote freelance role asks you to review and assess AI-generated content on law, government policy, and regulatory compliance. You check accuracy, citations, terminology, and how well the AI handles nuance across legislation, case law, and public policy. It suits people with a background in law, government, or policy who can write clear, structured feedback and work on their own schedule.
This remote contract role asks legal and policy professionals to check AI-generated content on legislation, case law, and government matters for accuracy and nuance.
