Company Description Teipsum is building the trust layer that makes AI agent labor contractable, auditable, and verifiable. On Teipsum’s substrate, every agent acts under enforced identity, scope, and authority, generating signed, audit-grade records that can be traced, replayed, and checked. The platform gives organizations direct control over enforcement and governance, so rule changes follow their decisions rather than vendor release cycles.
Teipsum runs its own operations on the same substrate, aligning product reality with customer requirements. The first customers are organizations in banking, finance, and other regulated industries that need provable AI agents before they can deploy them at scale.
Role Description As Founding CTO — Elixir/BEAM at Teipsum, you will lead the technical vision, architecture, and implementation of the core trust substrate for AI agents. You will design and build distributed, verifiable systems in Elixir/BEAM, set engineering standards, and establish security, reliability, and observability practices that match audit-grade expectations. Day to day, you will pair with other founders on product decisions, translate customer and regulatory requirements into technical designs, guide the roadmap, and write high-quality, production-ready code.
You will recruit and mentor an early engineering team, create processes for delivery and incident response, and represent Teipsum’s technical strategy in customer and investor conversations. This is a full-time remote role.
Qualifications

Excellent written and verbal communication skills, including ability to explain complex technical concepts to non-technical stakeholders.
Previous experience in fintech, banking, compliance-heavy SaaS, or adjacent regulated domains is highly beneficial.
Bachelor’s degree or higher in Computer Science, Engineering, or equivalent
