[Hiring] Principal Engineer @Rootshell Enterprise Technologies, Inc.

Role Description

We are seeking a highly experienced Principal Engineer specializing in Cybersecurity, Secure Cloud Architectures, and High-Performance Systems. This role requires expertise in Rust for security-critical components, Scala for distributed systems, and WebAssembly (WASM) for sandboxed execution. You will work on developing next-generation security platforms, real-time threat detection, and secure cloud services on AWS. As a key technical leader, you will drive end-to-end security strategies, optimize performance for cryptographic workloads, and ensure the resilience of large-scale distributed systems.

Key Responsibilities:

• Develop highly secure, performance-critical backend services using Rust (Tokio, Actix, Axum, Rocket).
• Build and scale distributed security applications with Scala (Akka, Play, ZIO, Cats).
• Implement WebAssembly (WASM)-based sandboxed execution environments for security-sensitive operations.
• Design and deploy cloud-native cybersecurity solutions on AWS (Lambda, ECS, DynamoDB, S3, API Gateway, CloudFront, KMS, GuardDuty, WAF, Security Hub).
• Develop advanced threat detection and response mechanisms leveraging real-time analytics and event-driven architectures (Kafka, NATS, RabbitMQ).
• Secure API development with OAuth, OpenID Connect, JWT, TLS, Mutual TLS (mTLS).
• Optimize cryptographic operations (encryption, hashing, digital signatures) with Rust and WASM.
• Enhance cloud security with Zero Trust frameworks (BeyondCorp, AWS Verified Access, Tailscale).
• Design authentication and identity management solutions using AWS Cognito, IAM, Keycloak.
• Deploy and manage security policies using Infrastructure as Code (Terraform, AWS CDK, CloudFormation).
• Implement real-time security monitoring using Prometheus, Grafana, OpenTelemetry, AWS Security Lake.
• Perform secure coding, vulnerability assessments, and automated security compliance checks (SAST, DAST, IaC Security).

Qualifications

• 17+ years of experience in backend development, cybersecurity, and distributed systems.
• Expertise in Rust (Tokio, Actix, Rocket, Axum) for secure, memory-safe applications.
• Proficiency in Scala (Akka, ZIO, Cats, Play) for building scalable security services.
• Strong experience with WebAssembly (WASM) for secure, sandboxed execution in cloud and edge environments.
• Deep knowledge of AWS security services (GuardDuty, WAF, Security Hub, IAM, Cognito, KMS, CloudTrail).
• Advanced understanding of Zero Trust architectures, encryption, and authentication (OAuth2, OIDC, JWT, TLS, mTLS).
• Proven expertise in cryptographic protocols (AES, SHA, RSA, ECC, HMAC, ECDSA).
• Experience with threat intelligence, SIEM, and security analytics tools (Splunk, ELK Stack, AWS Security Lake).
• Strong database security and performance optimization skills (PostgreSQL, DynamoDB, Redis, graph databases).
• Proficiency in Infrastructure as Code (Terraform, AWS CDK) and DevSecOps best practices.

Preferred Skills (Nice to Have)

• Experience in secure multi-party computation (SMPC) and homomorphic encryption.
• Knowledge of hardware security modules (HSMs) for cryptographic key management.
• Familiarity with blockchain security (smart contract audits, key management).
• Machine Learning for threat detection and anomaly detection.
• Federated Identity and Access Management (FIDO2, WebAuthn, SAML, SCIM).
