The work includes building reproducible environments, writing deterministic verifiers and reference solutions, and flagging ambiguous or unverifiable tasks.\n\nResponsibilities\nCreate realistic, challenging coding tasks for frontier AI models, drawn from repositories you know well\nDesign problems that require real engineering skill — subtle bugs, non-trivial features, meaningful performance work — not lookup or boilerplate\nBuild a reproducible environment for each task\nWrite deterministic verifiers that accept correct solutions across different valid implementations, while rejecting incorrect, incomplete, or hard-coded approaches\nProvide a reference solution showing how the task can be solved\nFlag tasks that turn out to be ambiguous or unverifiable rather than submitting them\n\nSkills\nHands-on expertise in at least one of Python, Java, Rust, Go, C++, or TypeScript\nSignificant hands-on expertise in at least one of: Python3, Java, Rust, Go, C++, or TypeScript\nDeep understanding of algorithms, data structures, and software engineering principles\nProven ability to debug complex systems, resolve bugs, and deliver effective optimizations\nExperience with large codebase refactoring and legacy system modernization\nTrack record of delivering high-impact features from conception through delivery\nStrong documentation and communication skills to articulate technical concepts clearly\nInterest in AI and its technical challenges — previous AI experience not required\n\nBenefits\nFully remote\n\nCompany Overview\nInvisible Technologies makes AI work. Our platform cleans, labels, and structures company data so it’s ready for AI. It was founded in 2015, and is headquartered in New York, New York, USA, with a workforce of 201-500 employees.
