About the Role

We are looking for an experienced Distributed Secure Network Hardware & Software Architect / DevOps Engineering Lead to join our engineering team on a part-time, hybrid basis. You will play a key role in designing, developing, and maintaining a secure, scalable, and highly available distributed infrastructure built on our custom self-managed private cloud environment.

This position combines software architecture, network security, infrastructure engineering, and DevOps practices, with a strong focus on C# / .NET development, Kubernetes, Argo CD, and GitOps-based deployments. We are seeking an engineer who can take ownership of architectural decisions, contribute to hands-on development, and build secure, production-ready infrastructure solutions. Knowledge in cryptography and HSM (Hardware Security Module) is a plus.

Key Responsibilities

• Design and implement secure, scalable, and fault-tolerant distributed network architectures.

• Develop and maintain backend services and infrastructure components using C# and .NET.

• Architect and integrate hardware and software components within distributed network environments.

• Design, deploy, and maintain our self-hosted private cloud infrastructure.

• Manage containerized applications and orchestration environments using Docker and Kubernetes.

• Implement and maintain GitOps-based continuous delivery workflows using Argo CD.

• Automate infrastructure provisioning, configuration, and deployment processes.

• Design secure communication mechanisms, authentication systems, and access control policies.

• Implement monitoring, logging, and observability solutions to ensure infrastructure reliability.

• Optimize system performance, scalability, fault tolerance, and high availability.

• Identify and address security vulnerabilities across networking, infrastructure, and application layers.

• Collaborate with engineering teams on system architecture, integration, and deployment strategies.

Required Qualifications

• Strong experience in C# and .NET development, particularly backend services and distributed applications.

• Solid understanding of distributed systems, microservices architecture, and network infrastructure.

• Hands-on experience with Docker and Kubernetes.

• Experience with Argo CD, GitOps principles, and automated deployment workflows.

• Strong knowledge of Linux server administration and system-level troubleshooting.

• Experience designing or managing self-hosted infrastructure, private cloud environments, or on-premises systems.

• Solid understanding of TCP/IP, DNS, routing, VPNs, firewalls, and secure network communication.

• Knowledge of cybersecurity fundamentals, encryption, authentication, authorization, and network security.

• Familiarity with infrastructure automation and configuration management.

• Experience with API development, service-to-service communication, and distributed application deployment.

• Strong problem-solving skills and the ability to work independently on complex technical challenges.

Nice to Have

• Experience with hardware-software integration, embedded systems, or edge computing.

• Knowledge of Software-Defined Networking (SDN) and network virtualization.

• Experience with peer-to-peer (P2P) systems and decentralized network architectures.

• Familiarity with Zero Trust security models, PKI, TLS/mTLS, and secure communication protocols.

• Experience with Prometheus, Grafana, or similar observability tools.

• Knowledge of Infrastructure as Code (IaC) and infrastructure automation.

• Experience building highly available and fault-tolerant private cloud environments.

• Familiarity with hardware-backed security technologies such as TPM, HSM, or secure boot.

What We Offer

• Flexible part-time working arrangements.

• A hybrid working model with a base salary and an ealy bird stock option plan.

• The opportunity to work on challenging distributed systems and private cloud infrastructure.

• Direct involvement in system architecture and technical decision-making.

• A collaborative environment with significant technical ownership.

• The opportunity to design and build a secure global infrastructure solution from the ground up.
