About Openmesh and Xnode
Currently, a handful of corporations control 90% of the world's data and IT infrastructure. This centralized control not only hinders innovation and raises privacy concerns but also perpetuates social inequality, scandals, and corruption. Openmesh is a cutting-edge open-source cloud infrastructure and global open data network that aims to store important global data without intermediaries. It is the largest open web3 data lake, covering 80% of the crypto and web3 ecosystem, and has plans to expand its data coverage to include public health and scientific research data.
Openmesh allows anyone to create their own decentralized data cloud, share data securely, and automate data cloud setup. Think of Openmesh as the internet's open data fabric, providing universal access to data without interference from regulators, governments, or corporations.
Core Products
- Xnode: Our flagship product that revolutionizes data cloud development. Xnode enables developers to build their own decentralized data clouds in a matter of minutes, with data connectivity, APIs, and powerful query and analytics capabilities. Xnode significantly reduces costs and deployment time.
- Pythia: A powerful analytics and query engine that transforms raw data into actionable insights. Pythia empowers users to design, visualize, and deploy data products.
- Unified APIs: A single endpoint for all crypto and web3 data, allowing universal access without licensing or setup fees.
Our Vision
Our mission is to democratize data and address information asymmetry on a large scale. We believe that access to reliable, unedited information is a fundamental right in a free and democratic society. Openmesh is built on core principles that prevent any single authority from altering or controlling its data. The entire technology stack is open-source and governed by an open-source community.

Responsibilities
Design and develop production-grade Solidity smart contracts
Build and test DeFi protocols and blockchain applications
Develop automated tests using Foundry
Analyze existing protocols and smart-contract architectures
Optimize contract execution and gas usage
Research blockchain protocols and emerging technologies
Identify and mitigate smart-contract security vulnerabilities
Work with backend and infrastructure engineers
Participate in code reviews and technical design discussions
Research MEV, transaction ordering, and protocol-level mechanisms when relevant
Requirements
Required:
Strong programming fundamentals
Experience with Solidity or another blockchain smart-contract language
Understanding of Ethereum/EVM architecture
Familiarity with Git and GitHub
Understanding of smart-contract security fundamentals
Ability to read and understand existing smart-contract code
Nice to have:

Experience with Uniswap, Aave, Compound, or similar protocols
Rust, Go, or TypeScript experience
Knowledge of EVM internals
MEV/arbitrage experience
Blockchain node/RPC experience
Previous DeFi or protocol development experience
Technical Hiring Process
We don't rely exclusively on interviews.
Our hiring process is designed to evaluate actual engineering ability:
1. Application & CV Review
We review your technical background and previous projects.
2. Technical Screening
A short technical discussion covering your experience and understanding of blockchain fundamentals.
3. Engineering Project
Qualified candidates receive a practical blockchain engineering assignment.
For example, candidates may be asked to build and test a small DeFi/treasury protocol, analyze an existing smart contract, or implement a blockchain-related component.
The project evaluates:
Code quality
Architecture
Solidity knowledge
Testing
Security
Problem-solving
Documentation
4. Technical Review
An engineer reviews the submitted project and discusses the implementation with you.
5. Final Interview
Discussion with the engineering team about your technical experience, interests, and potential role at Averiq Labs.
What We Value
We care more about what you can build than how many years you've worked.
We're particularly interested in engineers who:
Build projects outside of work
Read open-source protocol code
Understand why systems work, not just how to use them
Can independently investigate unfamiliar technologies
Care about security and correctness
Enjoy difficult technical problems
Compensation
Competitive compensation based on experience and technical ability, with additional consideration for exceptional blockchain engineering experience.
