Job Summary

IDIRA Secure Infrastructure Access (SIA) for RDP provides secure, brokered Remote Desktop access to Windows servers without exposing credentials or opening inbound network access. While the gateway targets Windows endpoints, our core infrastructure and engine run entirely on modern Linux and cloud-native architecture:

• Engineering Environment: Apple Mac workstations (macOS).
• Runtime & Infrastructure: Modern C++ running in Linux containers (Docker/Kubernetes), AWS Lambda, and cloud microservices.

We are searching for a Senior C++ Software Engineer to join our expanding SIA RDP team in Bulgaria. You will be part of a high-performing cross-functional team of developers, architects, and QA engineers, taking end-to-end ownership of core engine performance, protocol handling, and security.

• Mentor team members, fostering a culture of technical excellence and engineering rigor.

Qualifications

• Exceptional analytical, debugging, and root-cause analysis skills.
• Proven ability to independently navigate, understand, and learn complex distributed systems.
• Experience with modern CI/CD workflows and version control (e.g., Git, Jenkins, Artifactory).

The following will be consider as advantage:

• AI-Augmented Engineering: Practical experience leveraging modern AI developer tools (e.g., Claude Code, Cursor, Copilot) to explore unfamiliar codebases, plan complex tasks, and execute cross-repository implementations.

• Security & Protocols: Familiarity with secure network protocols (TLS/SSL), authentication mechanisms (LDAP, RADIUS, Kerberos), or OWASP standards.
