We’re Hiring: Blockchain Developer

Location: Doha, Qatar

Industry: Blockchain

Employment Type: Full-time

About The Role

As a Blockchain Engineer, you’ll play a critical role in shaping the architecture and

implementation of our core blockchain systems. You’ll work at the intersection of smart contract

development, protocol design, and system security, helping bring new decentralized products

and infrastructure to life. Whether designing efficient on-chain logic, scaling our platform across

L2s, or integrating with external protocols, you’ll own projects end-to-end and collaborate closely

with product, design, and fellow engineers. This is a high-impact role for someone who thrives in

a fast-paced environment and is excited to help build the future of blockchain/web3.

Missions & Responsibilities 

• Design and implement data extraction pipelines from multiple blockchains

  (EVM-compatible and non-EVM).

• Ability to design, implement, and deploy smart contracts on Ethereum or other relevant

  blockchains.

• Deep understanding of Blockchain technology (Solidity, Vyper), Oracles, and

  Decentralized Finance (Curve, Balancer, AMMs, Yearn, Aave, Synthetix ... etc): ideally,

  you have used and integrated these protocols before

• You can abstract the complexity of low-level smart contract interactions through scripting

  and REST APIs

• Participate in the engineering on-call rotation to ensure platform stability, monitor for

  production issues, and respond to critical incidents.

• Write thorough documentation and conduct peer code reviews.

• Work closely with product team to develop technical solutions from concept to

  production.

• Stay current with the latest developments in blockchain protocols, tooling, and standards

  (e.g., EIPs, ERCs, L2 scaling, etc.).

Requirements

• 5+ years of professional software engineering experience, with at least 3 years focused

  on blockchain development.

• Proven experience as a data engineer, with a focus on building and maintaining

  large-scale data pipelines.

• Strong skills in data processing, transformation, and working with complex datasets

  derived from blockchain sources.

• Proficiency in extracting and structuring on-chain data, with an emphasis on downstream

  data workflows.

• Familiarity with blockchain concepts (e.g., on-chain data structures, transactions)

• Solid understanding of DevOps practices and data infrastructure is a plus.

• Comfortable working with Golang and one or more smart contract languages (Solidity,

  DAML, Move, etc.).

• Understanding of blockchain fundamentals: consensus mechanisms, EVM, transaction

  lifecycle, gas optimization, etc.

• Experience with web3 libraries and tools (e.g., Hardhat, Foundry, ethers.js, web3.js).

• Strong experience in backend development with Go and good understanding of

  microservices architecture.

• Experience deploying and managing applications in kubernetes

• Comfortable working in a fast-paced startup environment with an ownership mentality.

Preferred Qualifications

• Experience with distributed systems or event-driven architectures.

• Familiarity with security best practices in API development.
