Original job description

The client is looking for a senior developer to speed up the fixing of vulnerabilities as part of reducing technological risk in their main department. The role covers three layers at once: application code, Windows and Linux operating systems, and services hosted in AWS. Document production solutions (Exstream, Kofax, Output Manager, PIOE) are within the scope to be fixed, even though they are not part of the requested qualifications. Monitoring is done via the ArmorCode dashboard, and the person guides the relevant teams toward structured handling, which relies on influence rather than hierarchical authority. The combination of development, infrastructure, and cloud, on a short-term assignment, limits the candidate pool.

Candidate wanted: A senior developer or technical specialist who has personally fixed vulnerabilities in Java code, on Windows and Linux servers, and in AWS, and who prioritizes based on criticality. This person moves from layer to layer without handoffs and gets the responsible teams to take action.

Key Requirements:

Vulnerability analysis and remediation (code, dependencies, operating systems, images, configurations)
Severity interpretation, technical risk assessment, and corrective measures
Java and Ruby software development, including secure development practices
Windows and Linux environments (administration, configuration, hardening, patching)
AWS: core services, security models, cloud vulnerability management
ArmorCode or equivalent vulnerability management and orchestration platform
End-to-end involvement across application, cloud, and infrastructure layers, and stakeholder coordination
Influential leadership, autonomy, problem-solving, communication, and the ability to explain complex concepts clearly
