Job Description

THE ROLE

We are expanding the Offensive Security Engineering team, meaning that there are many skill-sets and experiences required. Your place within the team will depend on your individual strengths and interests. To give you an idea of some of the areas that of expertise we are looking for an experienced Red Team Operator with a particular specialty in *nix and cloud environments.

Primary focus of this role will be to perform hands on offensive activities as part of Red Team engagements against Form3 endpoints, API and cloud assets. Some of the key projects/ workloads our team take on:

  • Developing proof of concept exploits, C2 implants and profiles.
  • Creating offensive security tools and implementing them to enhance our specific offensive security capabilities.
  • Testing Kubernetes and cloud-native (AWS, GCP and Azure) distributed system architecture.

WHAT WE'RE LOOKING FOR

  • Ability to analyse vulnerabilities, threats, procedures and architectural design, develop TTPs, produce reports and share intelligence.
  • Three years minimal of offensive security experience in cloud-based environments (Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) in both private and public (AWS, GCP, Azure) environments) and in one or more of the following verticals: network penetration testing, application (web, mobile) penetration testing, Red Team operations, application security assessments, and network exploitation operations.
  • Candidate should have the ability to perform targeted, covert penetration tests with vulnerability identification, exploitation, and post-exploitation activities with no or minimal use of automated tools.
  • Strong understanding of the following: Windows/Linux/Unix/Mac operating systems; OS and software vulnerability and exploitation techniques; commercial or open-source offensive security tools for reconnaissance, scanning, exploitation, and post exploitation (e.g. Mythic C2, Metasploit, Burp Suite); networking fundamentals (all OSI layers, protocols); Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) providers in both private and public (AWS, GCP, Azure) environments; DevOps; CI/CD pipeline, incident response; threat hunting; and familiarity with interpreting log output from networking devices, operating systems, and infrastructure services.
  • Strong programming skills, we are flexible on languages, we use Go as our main language for production so a willingness or interest to learn Go is fundamental. In security we write our own scripts for automation in Go, Python and other languages while contributing to open-source tools so we can utilise them.
  • Technical knowledge or experience developing proof of concept exploits and in house scripting, using interpreted languages such as Python, Ruby, or Perl, compiled languages such as Golang, Rust, C/C++, Swift, Objective-C or Java, and security tools or technology such as Firewalls, IDS/IPS, Web Proxies, DLP and the ability to articulate and visually present complex penetration testing and Red Team results is highly desirable.
  • Familiarity with macOS, Linux, containerisation and microservices architecture security concepts is also crucial to being successful in this role.
  • Knowledge of Kubernetes, securing clusters and meshes (Cilium is preferable), networking best practices and RBAC implementation (CKA, CKS qualifications are a plus).
  • Container security knowledge including container image provenance (Sigstore and Notary as examples) with an in-depth knowledge of container runtimes/ Docker, the security controls and best practice that surround microservice architectures.
