Software Engineer (Rust)

Job Title: Rust Developer – End-to-End Encryption (E2EE)

Location: Dubai

Salary: 20-25k

We’re seeking a skilled Rust Developer with deep expertise in End-to-End Encryption (E2EE) to build secure, privacy-first applications. This role is ideal for someone passionate about cryptography, data protection, and building performant, security-critical systems from the ground up.

Key Responsibilities

• Develop high-performance, secure applications using Rust
• Design and implement E2EE in messaging, file storage, and communication platforms
• Integrate cryptographic libraries (e.g., libsodium, RustCrypto, ring, OpenSSL)
• Architect robust key management and authentication systems
• Optimize security features for low-latency environments
• Conduct threat modeling, security audits, and vulnerability assessments
• Write safe, concurrent, and efficient Rust code
• Collaborate with cross-functional teams to ensure end-to-end secure architecture

Requirements

• Strong proficiency in Rust, with a track record of writing security-critical code
• Hands-on experience with cryptographic algorithms like Diffie-Hellman, AES-GCM, ChaCha20, RSA, ECC
• Solid understanding of secure communication protocols (TLS, QUIC, Noise Protocol)
• Experience with asynchronous Rust frameworks (tokio, async-std)
• Familiarity with threat modeling, attack surfaces, and data privacy principles
• Understanding of secure SDLC, CI/CD pipelines, and containerization (Docker, Kubernetes)
• Proficient in Git and modern DevOps workflows

Nice to Have

• Experience with Matrix Protocol, Signal Protocol, or WireGuard
• Knowledge of Zero-Knowledge Proofs (ZKP), Multi-Party Computation (MPC), or homomorphic encryption
• Exposure to Web3 cryptography, blockchain security, or decentralized identity systems
• Familiarity with FIDO2, WebAuthn, or multi-factor authentication (MFA)
