Principal Systems Engineer, Security-Critical Infrastructure @ Stigning Company

Lead Stigning as an engineering lab focused on security-critical infrastructure, post-quantum cryptography, distributed systems, protocol correctness, and high-assurance backend platforms.

Architect and implement systems across blockchain infrastructure, cryptographic protocols, IIoT security, resilient backend services, and distributed execution environments using Rust, Go, C++, Solidity, and formal/adversarial design methods.

Design post-quantum and quantum-resilient infrastructure for secure communication, key management, protocol migration, and long-term cryptographic agility in systems exposed to adversarial and high-reliability requirements.

Develop formal specifications, threat models, system invariants, state-machine models, verification-oriented documentation, and security architecture for protocols and platforms where correctness must be reasoned about explicitly.

Engineer high-performance and low-level systems with attention to memory safety, concurrency, latency, fault tolerance, resource efficiency, deployment reproducibility, and operational resilience.

Incubate and develop original infrastructure initiatives such as verifiable execution layers, Solana security operations tooling, post-quantum IIoT components, and verification-centered blockchain infrastructure.

Build and contribute to open-source projects involving post-quantum cryptography, blockchain infrastructure, verifiable execution, distributed systems, IIoT security, and secure protocol design.

Provide technical leadership across research, architecture, implementation, documentation, and security review, defining engineering standards for systems where failure is structural, operational, or adversarial rather than merely cosmetic.
