Description

Project description
Our client, an established online marketplace, is looking for an experienced network security engineer to join its security team on a temporary basis. You’ll take ownership of the Akamai web application firewall (WAF) and the firewall rule base at a time when the company is formalising its security framework and investing in moving faster. This is a hands-on role where you’ll see the results of your work quickly.
What you’ll do
  • Configure and fine-tune the Akamai WAF, including policies, custom rules, exceptions and false positive handling
  • Review and clean up the existing firewall rule base: identify outdated, unused or overly broad rules, remove them safely and document what remains
  • Analyse firewall and WAF logs to spot issues, unusual traffic and attacks
  • Work closely with the cloud and infrastructure teams
  • Contribute to network security design where it touches the WAF and cloud environments
Must have
  • Hands-on Akamai WAF configuration and tuning experience
  • Firewall rule base review and clean-up in a live environment
  • Firewall log analysis
  • Solid network security fundamentals
  • Experience working alongside cloud and infrastructure teams
  • Ability to work independently and start in mid-November
  • Fluent German and English
Nice to have
  • Experience with other WAF platforms such as Cloudflare, Imperva, F5 or FortiWeb
  • Familiarity with Akamai’s wider security products, such as bot management and DDoS protection
  • Experience with Palo Alto, Fortinet or Check Point firewalls
  • Rule base tools such as Tufin or AlgoSec
  • Cloud security experience (AWS, Azure or GCP)
  • Experience in a smaller or fast-growing company where processes are still being built
  • Certifications such as CISSP, CCNP Security or Akamai certifications
