About the Role What if your deep mathematical training could directly shape how AI understands and reasons about rigorous proof? We're looking for Formal Verification Scientists to translate advanced mathematics into machine-verifiable Lean 4 formalizations — working at the very frontier of what proof assistants can express, capture, and automate. This is a fully remote, flexible contract role built for mathematicians who love precision, structural elegance, and the challenge of pushing formal verification beyond its current limits. - Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week What You'll Do - Translate informal mathematical proofs into clean, structured Lean 4 formalizations with an emphasis on clarity, correctness, and reproducibility - Analyze both generic and domain-specific proofs to identify gaps, hidden assumptions, and formalizable sub-structures - Construct formalizations that test the limits of existing proof assistants — especially in areas where automated tools struggle or fail - Collaborate with AI researchers to design, refine, and evaluate strategies for improving formal verification pipelines - Decompose complex arguments into well-structured lemmas and proof scripts aligned with mathematical best practices - Investigate where automated provers break down and articulate the underlying reasons — missing libraries, complexity barriers, insufficient scaffolding - Create Lean proofs that reveal deeper patterns or generalizations implicit in the original mathematics Who You Are - Holds a Master's degree or higher in Mathematics, Logic, Theoretical Computer Science, or a closely related field - Has a strong foundation in rigorous proof writing across areas such as algebra, analysis, topology, logic, or discrete mathematics - Has hands-on experience with Lean (Lean 3 or Lean 4), Coq, Isabelle/HOL, Agda, or a comparable proof assistant — Lean strongly preferred - Deeply enthusiastic about formal verification, proof assistants, and the future of mechanized mathematics - Able to translate dense, informal arguments into precise, machine-verifiable form with structural clarity Nice to Have - Familiarity with type theory, the Curry-Howard correspondence, and proof automation tools - Experience contributing to large-scale formalization projects such as Mathlib - Exposure to theorem provers where automated reasoning frequently fails or requires significant manual scaffolding - Prior experience with data annotation, data quality evaluation, or AI training workflows - Strong communication skills for explaining formalization decisions, edge cases, and reasoning strategies Why Join Us - Work on cutting-edge AI projects alongside leading research labs and AI teams - Fully remote and flexible — work when and where it suits you - Freelance autonomy with the structure of meaningful, intellectually demanding work - Contribute to pushing the boundaries of what formal verification and AI can achieve together - Potential for ongoing work and contract extension as new projects launch

About the Role Data breaches don't happen in theory — they happen in the real world, across cloud platforms, SaaS tools, and enterprise systems. We're looking for experienced data security professionals who understand how sensitive information actually gets exposed, and what it takes to detect and stop it. At Alignerr, we partner with the world's leading AI research labs to build and train frontier AI models. Your hands-on expertise in data loss prevention (DLP) and security operations will help shape how AI reasons about sensitive information risk — making these systems smarter, safer, and more grounded in reality. - Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week What You'll Do - Analyze realistic data security and DLP scenarios across cloud, SaaS, and enterprise environments - Classify data sensitivity levels, exposure paths, and policy violations - Evaluate prevention, detection, and incident response strategies - Generate, label, and validate data security cases used to train and benchmark AI systems - Apply your practical security knowledge to help AI better understand how data risk plays out in the wild Who You Are - 2+ years of experience in data security, compliance, or security operations - Familiar with DLP tools, data classification frameworks, and privacy or regulatory concepts (GDPR, HIPAA, CCPA, etc.) - You've seen how data risk actually unfolds in real environments — not just in textbooks - Strong analytical thinking and attention to detail - Comfortable working independently and asynchronously Nice to Have - Experience with cloud security platforms (AWS, Azure, GCP) or SaaS security tooling - Background in security architecture, insider threat, or data governance - Familiarity with AI or machine learning workflows Why Join Us - Work directly on cutting-edge AI projects with top-tier research labs - Fully remote and flexible — work on your own schedule - Freelance perks: autonomy, variety, and global collaboration - Your domain expertise has direct impact on how frontier AI models understand and handle sensitive data - Potential for ongoing work and contract extension
