Software Developer III
Cybersecurity Engineering – Penetration Testing & SIEM Integration
Austin, TX
Onsite
6 month contract
This isn’t a traditional developer role.
This is for someone who can write clean, secure code and also thinks like an attacker.
You’ll sit within the Office of the CISO and help modernize how cybersecurity engineering gets done. Automation over manual effort. Integration over silos. Data driven detection instead of reactive response.
If you’ve built APIs one week and tuned a Kali Linux lab the next, you’re going to feel right at home here.
You’ll design and develop secure APIs, automation scripts, and microservices that support penetration testing workflows. You’ll build integrations between vulnerability scanners, testing platforms, and enterprise SIEM tools. You’ll develop ingestion pipelines that normalize telemetry into Splunk and other platforms so security teams can actually detect what matters.
This role directly supports Zero Trust initiatives, continuous monitoring, and broader security operations modernization. It’s hands on engineering with real impact.
Must haves
• 8+ years of advanced experience building security automation and platform integrations
• 8+ years of hands on experience with penetration testing tools and Kali Linux environments
• Strong professional software development background
• Experience developing REST APIs and integrating enterprise systems
• Strong scripting skills in Python, Bash, PowerShell, or similar
• Experience deploying and administering Linux systems
• Experience working with SIEM platforms such as Splunk or Sentinel
• Strong understanding of secure coding practices and cybersecurity fundamentals
Nice to have
• Experience building security data pipelines and SIEM integrations
• Experience with containerization and virtualization such as Docker or VMware
• Experience designing scalable, resilient security tool architectures
• Experience in regulated or government environments
• Certifications such as OSCP, CEH, Security+, CISSP, or Splunk certification
You’ll also help build and maintain Kali Linux based testing infrastructure, develop custom exploit scripts and proof of concept code, automate alert enrichment and correlation workflows, and align development efforts with CSOC detection requirements.
This role requires technical depth, creativity, and the ability to operate independently in a structured, compliance driven environment. Documentation, version control, CI/CD, and disciplined change management all matter here.
At iSphere, we look for engineers who enjoy building tools that make security smarter and more scalable. If you’re someone who sees automation as the future of cybersecurity operations and wants to help drive that transformation onsite in Austin, let’s connect.
