Patternica

About the Project

A decentralized operating system and ecosystem that empowers people with full control over their digital identity and data. We focus on privacy, security, and independence by providing tools for secure communication, personal data storage, and digital ownership — all without relying on centralized servers or corporations.

The project is already in progress, and you will join an experienced team.

Responsibilities

• Design, develop, and maintain core components of an offline Operating System, ensuring performance, reliability, and scalability.
• Work with multiple programming languages (C, C++, Rust, Go, or others depending on module requirements).
• Implement low-level system functionality: memory management, file systems, process scheduling, and device drivers.
• Develop secure offline communication protocols and ensure system stability in disconnected environments.
• Write clean, efficient, and well-documented code aligned with modern engineering practices.
• Debug, test, and optimize system components across multiple hardware environments.
• Collaborate with a cross-functional team to deliver complete, production-ready solutions.
• Research and integrate new technologies, libraries, and approaches to improve OS architecture.
• Participate in code reviews and help establish best practices for OS development.
• Prepare technical documentation for internal and external stakeholders.

Required Skills (Tech Stack)

• Systems programming: strong experience with C, C++, Rust, or Nim.
• Operating systems fundamentals: memory management, process scheduling, file systems, inter-process communication (IPC).
• Security & cryptography: encryption, authentication, secure communication protocols.
• Linux expertise: low-level Linux internals, kernel modules, or custom OS builds.
• Networking: TCP/IP, peer-to-peer networking, sockets, distributed communication.
• Strong problem-solving skills in low-level and distributed environments.

Nice to Have (Optional)

• Nim for performant, Python-like syntax compiled to efficient binaries.
• Nix / NixOS: reproducible builds, package management, declarative infrastructure.
• Distributed systems: consensus algorithms (Raft, Paxos), gossip protocols, scalability.
• Virtualization & containers: Docker, Kubernetes, QEMU, lightweight VMs.
• Cross-platform development across multiple hardware architectures.
• Blockchain/Web3: decentralized identity, digital signatures, ledger-based ownership.

What we offer

• Competitive salary based on skills and experience.
• 20 days of paid vacation and 3 sick leave days per year.
• Corporate accountant.

About the Project

Our client from Switzerland is developing a digital platform to connect investors and startup founders through events and networking opportunities.

You’ll be responsible for building and integrating the event website on WordPress and developing a custom API to connect the platform’s components and external services.

The project is hosted on Microsoft Azure, so hands-on experience with Azure is required.

Responsibilities

• Develop and maintain the event website on WordPress.
• API development (any modern technology is acceptable).
• Deploy and support the project in Azure.
• Collaborate with the design team and non-technical stakeholders.
• Build and maintain a REST API serving tracks, sessions, fixed IDs, and update timestamps.
• Develop a custom WordPress plugin with a dedicated database layer (beyond standard WP posts).
• Ensure GDPR compliance and security (HTTPS, API key/OAuth, audit logs, versioning).
• Deliver a future-proof and extensible architecture to support future redesigns and partner integrations.

Requirements

• 4–5 years of commercial experience in web development.
• Strong knowledge of WordPress (themes, plugins, custom modules).
• Experience developing and integrating APIs (REST, GraphQL, or similar).
• Hands-on experience with Azure (deployment, setup, configuration).
• English level B2–C1 — ability to communicate clearly with the client.
• Responsibility, independence, and good communication skills.
• Ready to start ASAP

Interview process:

1. HR Interview
2. Technical interview (30 min, conversational style)
3. Final intro with client

What we offer
