Founding DevOps Engineer (SRE) @ AI Identity Cybersecurity Venture, Berlin

This is an Atlantic portfolio venture.

About the Venture

We are building a cyber risk platform that helps enterprises understand, measure, and reduce identity risk at scale. We turn complex identity and security data into clear, actionable insights that CISOs and CTOs can trust. Founded by experienced cybersecurity leaders with backgrounds in Israeli intelligence, we are recently funded and building from scratch. The problem is real, the market is large, and we are moving quickly.

About the Role

This is a founding infrastructure hire. You will design, build, and operate the entire cloud infrastructure of the platform from day one, owning everything from AWS environments and CI/CD pipelines to container orchestration and observability. You will work directly with a technical CEO and CPTO, alongside backend and AI engineers, to build a secure, scalable, production-grade SaaS from scratch. The role is hybrid, based in central Berlin, and carries real ownership over how the platform runs and scales.

What you'll do

• Design and operate the core cloud infrastructure on AWS, including networking, IAM, compute, storage, and security boundaries

• Build and maintain Infrastructure as Code using Terraform for repeatable, auditable, and secure deployments

• Design and operate CI/CD pipelines for fast, safe, and reliable delivery across all services

• Own containerised workloads using Docker and Kubernetes (EKS), including deployment, scaling, and runtime security

• Implement observability across the platform using metrics, logs, and traces (Prometheus, OpenTelemetry, Grafana)

• Operate and secure data infrastructure (PostgreSQL, graph databases) in production

• Embed security best practices across infrastructure, including least privilege IAM, network isolation, and Zero Trust principles

• Partner closely with backend and AI engineers to design secure service boundaries and deployment models

• Troubleshoot and resolve production incidents across infrastructure, networking, and application layers

• Establish DevOps, SRE, and operational best practices as the company scales

• Support compliance readiness by enabling controls, logging, and evidence collection for security frameworks

About You

You are someone who builds infrastructure from scratch and takes pride in doing it properly. You are comfortable owning the full stack of cloud operations, making decisions without a lot of oversight, and working closely with a small engineering team where your choices directly shape the platform. Security is not an afterthought for you, it is part of how you think about everything.

• 5+ years of DevOps / SRE experience, with strong hands-on AWS production experience

• Deep knowledge of AWS networking, VPC, subnets, ALB, security groups, and IAM

• Hands-on with Docker, Kubernetes (EKS), and containerised workloads

• Experience building and maintaining CI/CD pipelines (GitHub Actions or similar)

• Strong Terraform experience for Infrastructure as Code

• Experience operating PostgreSQL (RDS / Aurora) and graph databases such as Neo4J

• Comfortable with monitoring and observability tools (Grafana, OpenTelemetry, Prometheus)

• Ability to code in Python

• Experience supporting and maintaining production SaaS platforms

• Excellent English, written and spoken

Nice to have:

• Experience with Go or Java

• MLOps experience

• Background in security architecture, identity security, or security engineering

• Familiarity with compliance frameworks (NIS2, DORA, ISO 27001, SOC 2)

• Understanding of OAuth/OIDC, SSO, SCIM, RBAC/ABAC, and identity protocols

• Familiarity with cloud identity controls (IAM, CloudTrail, Azure Entra ID)

• Experience with SIEM platforms (Splunk, Sentinel, QRadar)

• Knowledge of Zero Trust, least privilege, and continuous verification principles

• Experience with AI/LLM security or agent sandboxing

Why Join

This is a chance to be the founding DevOps / infrastructure person at a funded cybersecurity company, with real ownership over how the platform is built, secured, and operated. You will work directly with a technical CEO and CPTO, with fast iteration and strong alignment. Identity risk, AI-driven security, and SaaS access control are among the most interesting and fastest-growing areas in enterprise security. The team is small, the autonomy is high, and the infrastructure decisions you make will define the platform.
