About this role · Stem

About the Role What if your deepest mathematical knowledge could directly shape how AI reasons about formal proof — permanently expanding the boundary of what machines can verify and understand? We're looking for mathematicians with serious formal verification experience to translate advanced mathematical arguments into machine-verifiable Lean 4 proofs. This isn't routine formalization work. You'll be operating at the frontier — tackling proofs that push or exceed the current limits of automated proof assistants, and helping leading AI research teams understand exactly where those limits lie and why. This is a fully remote, flexible contract role built for mathematicians who think precisely, work independently, and care deeply about the structure underlying rigorous argument. - Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week What You'll Do - Translate informal mathematical proofs into clean, structured, machine-verifiable Lean 4 formalizations - Analyze proofs across domains — algebra, analysis, topology, logic, discrete mathematics — identifying hidden assumptions, gaps, and formalizable sub-structures - Construct formalizations that stress-test the limits of current proof assistants, and clearly articulate where and why they struggle - Collaborate with AI researchers to design and refine formal verification pipelines and evaluation strategies - Develop reproducible, well-structured proof scripts aligned with mathematical best practices and Lean idioms - Provide expert guidance on proof decomposition, lemma selection, and structuring strategies for formal models - Formalize classical results and compare machine-verifiable structures against textbook arguments to surface deeper patterns and generalizations Who You Are - Holder of a Master's degree or higher in Mathematics, Logic, Theoretical Computer Science, or a closely related field - Deeply trained in rigorous proof construction across core mathematical areas - Experienced with Lean (Lean 3 or Lean 4), with Lean 4 strongly preferred — or with comparable systems such as Coq, Isabelle/HOL, or Agda - Genuinely passionate about formal verification, proof assistants, and mechanized mathematics - Able to take a dense, informal mathematical argument and render it in a form a machine can understand — without losing mathematical meaning - Self-directed and comfortable working asynchronously at a high level of precision Nice to Have - Experience with large-scale formalization projects such as Mathlib - Familiarity with type theory, the Curry-Howard correspondence, and proof automation tools - Exposure to theorem provers in settings where automated reasoning frequently requires manual scaffolding - Prior experience with data annotation, evaluation systems, or structured data quality workflows - Strong ability to communicate formalization decisions, edge cases, and reasoning strategies clearly in writing The Ideal Candidate You're a mathematically mature problem-solver who finds genuine satisfaction in taking an elegant human argument and expressing it in a form that a machine can verify. You appreciate structural precision, notice the gaps that automated tools miss, and are energized — not frustrated — by the places where formal verification is still an open problem. You work well independently, document your reasoning carefully, and enjoy contributing to something at the actual edge of what's possible. Why Join Us - Work directly on cutting-edge AI research projects alongside world-leading research labs - Fully remote and flexible — structure your hours around deep work, on your schedule - Freelance autonomy with access to some of the most intellectually challenging mathematical problems in AI today - Exposure to advanced LLMs and insight into how formal reasoning capabilities are built and evaluated - Potential for ongoing work and contract extension as new projects launch

About this role

Overview We’re looking for experienced computational biologists and bioinformaticians to help train AI models. You’ll design realistic analysis tasks from your own practice, run them through frontier AI systems, and grade what comes back against a professional standard. The models can talk fluently about biological data analysis. What they can’t yet do reliably is the real work: QC an RNA-seq count matrix, prioritize variants, diagnose a batch effect, or audit a pipeline. Your judgment of when a result is real becomes the benchmark those models are measured against. What you’ll actually do - Design realistic analysis tasks from your own workflows: the scenario, the prompt, and the files an agent would need (count matrices, sample sheets and metadata, VCFs, pipeline logs and QC output, analysis notebooks). - Run tasks through frontier AI agents and grade the deliverable (an analysis report, annotated table, figure set, or notebook) against the standard you’d hold a colleague to. - Write clear grading rubrics (the right normalization, the right multiple-testing correction, the right biological reading) and explain why a response passes or fails. - Flag concrete failures with evidence: batch effects and confounders ignored, wrong statistical test or uncorrected p-values, misused reference version, silently dropped samples, or code that doesn’t do what the narrative claims. Problems draw on whatever you know best: - Genomics and variant interpretation. - Bulk and single-cell transcriptomics. - Proteomics, metabolomics, and multiomics integration. - Population and statistical genetics. - Machine learning applied to biology. Roles this fits Common backgrounds: Bioinformatics Scientist, Genomics Data Scientist, Computational Biologist. What we look for - 3+ years hands-on analyzing real biological data in industry, an academic lab, or a research institute (counted after undergraduate study). - You write, debug, and can explain your own analysis code in Python and/or R (at least one required, both preferred). - Depth in at least one of: genomics and variant interpretation; bulk or single-cell transcriptomics; proteomics / metabolomics / multiomics; population and statistical genetics; ML applied to biology; clinical genomics; metagenomics or phylogenetics. - You’ve owned a multistep analysis end to end, from raw or messy data to final interpretation, and can judge whether a result is real (normalization, batch effects, multiple-testing correction, biological interpretation). - Master’s or PhD (or current PhD candidate) in biology, bioinformatics, biostatistics, computer science, or a related field, completed in the U.S., Canada, Europe, or the UK. - Clear written English, comfort with ambiguity, and familiarity with AI/LLM tools like Claude or ChatGPT. - Based in the United States, Canada, or the UK (Ireland and Australia may also be accepted).
