Go (Golang): Required for backend development and high-performance system components.

Node.js: Essential for server-side application logic and scalable backend services.

React & React Native: Used for developing secure, responsive web and mobile application frontends.

C/C++: Recommended for low-level integration with hardware, such as USB keys and portable SSDs.

AI & Machine Learning Integration

ML Frameworks: Deep experience with TensorFlow, PyTorch, ONNX, or OpenVINO for deploying AI modules.

AI Implementation: Ability to integrate intelligence for threat scoring, anomaly detection, and data classification.

Inference Pipelines: Proven experience building and deploying ML models for production using REST or gRPC pipelines.

Security & Cryptography Tools

FIPS Validated Libraries: Experience working with CorSSL (a FIPS 140-3 Level 1 validated drop-in replacement for OpenSSL) or similar validated cryptographic modules.

PQC Algorithms: Practical implementation of Post-Quantum Cryptography (PQC) handshakes, specifically using algorithms like Kyber and Dilithium.

Standards & Protocols: Advanced knowledge of TLS 1.3, PKI (Public Key Infrastructure), and secure authentication mechanisms.

Blockchain: Development experience with blockchain for AI-driven audit trails and trust scoring systems.

Government Compliance & Testing Tools

FIPS 140-3 Validation: Understanding of the CMVP (Cryptographic Module Validation Program) submission process and requirements.

Algorithm Testing: Experience with CAVP (Cryptographic Algorithm Validation Program) testing for NIST-approved and PQC algorithms.

Certification Standards: Familiarity with international and federal standards including Common Criteria (CC), CSfC, and DoD STIGS/APL requirements.

Infrastructure & Monitoring

Telemetry Dashboards: Ability to build real-time data visualization tools for AI analytics and classification telemetry.

Sovereign Platform Architecture: Experience designing architectures that span Admin Consoles, Desktop Apps, and Mobile Apps while maintaining security across hardware interfaces.

✅ Qualifications

Experience: 8+ years of full-stack development experience, with a focus on security-centric or data-driven systems.

Technical Stack: Expert proficiency in Go (Golang), Node.js, and React/React Native.

Security & Crypto: Deep understanding of TLS 1.3, PKI, and secure authentication. Familiarity with PQC algorithms is highly preferred.

AI/ML Integration: Experience deploying machine learning models (e.g., TensorFlow, PyTorch) into production environments via REST/gRPC pipelines.

Compliance Awareness: Knowledge of government security standards such as FIPS 140-3.
