Job description

What we’re building

The Mawari Network orchestrates a decentralized ecosystem of GPU-powered nodes running the Mawari Engine, a proprietary rendering and streaming stack optimized for XR. We leverage Web3 principles to ensure scalability, transparency, and fairness in the network.

Our blockchain layer is the backbone of this ecosystem, enabling staking, licensing, reward distribution, and coordination across thousands of distributed nodes.

Why work with us

• Proven technology: 40+ XR deployments worldwide.
• Strong industry partnerships with leading XR, telecom, and blockchain players.
• Visionary, experienced founding team.
• Recently funded expansion phase with a focus on scaling Web3 infrastructure.
• Opportunity to define the future of decentralized XR streaming.

About the role – Senior Blockchain Engineer

As a Senior Blockchain Engineer at Mawari, you’ll take a leading role in architecting, building, and scaling the decentralized backbone of the Mawari Network. You will design and deploy smart contracts, manage tokenomics-critical infrastructure, and lead blockchain initiatives from concept to production.

This role is both technical and strategic, you’ll be hands-on with code while mentoring other engineers, guiding architecture, and ensuring production-grade reliability at scale.

Key responsibilities

Blockchain & decentralized systems

• Design and develop secure, efficient, and scalable smart contracts (Solidity) for EVM-compatible chains, with a focus on Arbitrum Orbit.
• Architect tokenomics-critical systems: staking, licensing, delegation, and reward distribution.
• Implement secure, transparent, and auditable governance and coordination mechanisms.
• Work on bridging, interoperability, and multi-chain strategies.
• Optimize for gas efficiency, throughput, and reliability across production workloads.

Distributed Infrastructure

• Collaborate with backend and infrastructure teams to ensure seamless integration between on-chain logic and off-chain services.
• Contribute to the design of high-availability systems capable of supporting thousands of active nodes.
• Integrate monitoring and telemetry (Prometheus, Grafana, OTel) into blockchain workflows.

Leadership & collaboration

• Lead blockchain projects from design to deployment, ensuring best practices in security, scalability, and maintainability.
• Partner with product, legal, and business teams to align blockchain systems with network tokenomics, compliance, and long-term vision.
• Stay ahead of ecosystem developments (Arbitrum, Ethereum L2s, DA layers) and bring innovative solutions to the team.

Education and experience

Required:

• 5+ years in software engineering, with at least 3+ years in blockchain/EVM development.
• Strong experience with Solidity and EVM-compatible networks (preferably Arbitrum, Optimism, and Polygon).
• Demonstrated success designing and deploying smart contracts in production environments.
• Deep understanding of decentralized architectures: staking, validator networks, delegation, DA layers, etc.
• Experience with gas optimization, contract security audits, and DeFi/Web3 security best practices.
  Strong background in distributed systems and high-availability architectures.
• Proven leadership: mentoring engineers, leading projects, setting technical direction.
  
  

Nice to Have:

• Experience with Arbitrum Orbit / Nitro stack.
• Knowledge of L3 or rollup architectures, DA integrations, and bridging.
• Contributions to open-source blockchain projects.
