• Cross-layer collaboration: Work closely with network and hardware engineers to ensure software interfaces seamlessly with routers, access points, and local gateways.
• Security & compliance: Ensure data protection and secure network operations across geographies and jurisdictions.
• Mentorship & technical leadership: Guide junior engineers, define DevOps best practices, and enforce reliability across the stack.
  
  

Qualifications

• Backend Development: Advanced in Node.js and/or Python; experience with event-driven architectures and API design.
• Frontend Development: Skilled in React (preferred), Vue, or Angular for building operational dashboards and monitoring tools.
• Cloud & DevOps: Strong command of AWS (Lambda, EC2, ECS), Vercel, Terraform, CI/CD pipelines, and infrastructure automation.
• Networking & Systems: Familiarity with Linux networking, routing, and service orchestration at scale; experience in telecom, mesh, or IoT systems is a major plus.
• Database Design: Expert in both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB, DynamoDB, Redis) for high-availability, real-time analytics.
• Monitoring & Logging: Experience with Prometheus, Grafana, Datadog, or similar tools.
• Security & Compliance: Knowledge of data security, identity management, and encryption standards.
• (Nice to Have) Blockchain/DePIN: Exposure to tokenized networks, wallets, or smart contract integrations.
  
  

What We Offer

A chance to work at the cutting edge of telecommunciations, Web3 technology and real-world impact.

An opportunity to influence the development of a groundbreaking platform that bridges the gap between blockchain and physical infrastructure.

A flexible & remote working environment with the option to travel.
