Co-Founder & CTO (gn) @ Agentic AI Cybersecurity Platform, Berlin

Join to apply for the Co-Founder & CTO (gn) @ Agentic AI Cybersecurity Platform, Berlin role at Atlantic.

About the Venture

We are building a next-generation Identity + AI Cybersecurity platform designed to secure how modern SaaS systems, users, and AI agents interact. Our platform combines identity modeling, real‑time policy enforcement, and AI‑driven risk analysis to help enterprises manage access, trust, and security in an increasingly agent‑driven world.

Having just secured pre‑seed funding, we are now moving into build mode. You will join a technical CEO and early founding team in Berlin to architect, design, and ship the core platform from day one.

About the Role

We are looking for a deeply technical Founding CTO (or even a Founding Engineer) who will take full ownership of the platform architecture and build the first version of the product. This is a hands‑on role where you will spend meaningful time writing production code while defining the long‑term direction for engineering, security, infrastructure, and team growth.

Responsibilities
  • Own the full technical architecture across identity, AI agent systems, and enforcement
  • Design and implement identity models, permission graphs, token lifecycle, and SaaS risk flows
  • Build the agent identity model, sandboxing framework, trust scoring, and behavior engine
  • Write production‑grade backend code (4–6 hours/day in the early stage)
  • Lead engineering execution across roadmap planning, sprints, and delivery
  • Build core services including connectors, policy engine, risk engine, and real‑time enforcement
  • Partner with the CEO on system design, product direction, and technical strategy
  • Support enterprise customers with technical deep dives, PoCs, and security validation
  • Maintain high standards of security, reliability, and architecture
  • Define and establish the long‑term technology strategy and data infrastructure
  • Hire, lead, and scale an in‑house engineering team
  • Manage data privacy, secure storage, and analysis frameworks
  • Contribute directly to building Europe’s most advanced cybersecurity platform
Requirements
  • Significant experience in backend engineering and system architecture
  • Ideally, exposure in technical leadership roles
  • Experience shipping complex distributed systems
  • Deep understanding of OAuth/OIDC, identity flows, API keys, tokens, scopes
  • Knowledge of RBAC/ABAC or fine‑grained access systems
  • Familiarity with Zero Trust principles and integration security
  • Experience with AI/LLM systems or ability to learn fast
  • Strong security mindset and understanding of modern attack surfaces
  • Experience integrating with SaaS APIs
  • Ability to move fast and operate independently
  • Experience with Terraform and cloud deployments
  • Prior startup experience and strong founder mentality
Nice to Have
  • Experience with agent orchestration or sandboxing
  • Experience with event‑driven or streaming systems (Kafka, Pub/Sub)
  • Knowledge of policy engines
  • Experience with token analysis or credential hygiene
  • Familiarity with cloud IAM (AWS/GCP/Azure)
  • Experience with risk scoring or anomaly detection
  • Understanding of graph databases or unified identity graphs
  • Prior cybersecurity or identity experience
  • Product leadership or prior founder experience
Why Join Us?
  • Co‑founder equity with meaningful upside
  • Full technical ownership
  • Founding team influence and responsibility
  • Fast‑paced environment with customer exposure and PoCs
  • Cutting‑edge work across identity, SaaS security, and AI agent governance
  • Strong learning curve and growth potential
  • Berlin location with hybrid flexibility
  • Direct impact on building Europe’s leading cyber platform
