Senior Blockchain Engineer

Spexi is a drone technology company on a mission to make ultra-high-resolution geospatial imagery more accessible than ever before, empowering humanity to make better decisions about the physical world.

We’re building an exciting new two-sided marketplace called the Spexi Network, powered by drones and blockchain technology. It's the world’s first Fly-to-Earn platform that enables drone pilots to earn rewards for flying and collecting aerial imagery. It also enables organizations of all sizes to quickly and easily access high-resolution aerial imagery and valuable derivative data, powering remote monitoring of buildings, infrastructure, natural resources, and more. Our goal is to guide their decision-making and help them better plan and react, without needing to own drones or hire pilots.

We’re looking for a Senior Blockchain Engineer to drive innovation in our blockchain-based network, enabling secure validation, provenance tracking, and decentralized verification for drone-captured data.

You’ll collaborate with a dynamic team to design and implement the underlying technology that powers our decentralized network, solving cutting-edge challenges in Web3 and geospatial systems.

RESPONSIBILITIES:

• Write and deploy EVM-compatible, gas-efficient smart contracts for Proof of Capture, Data License-to-Access NFTs, and tokenization.

• Architect decentralized protocols for secure image data availability

• Solve Web 2.0–Blockchain challenges, including indexing blockchain data into Postgres DBs, optimizing gas costs for transactions, and managing private keys securely.

• Leverage IPFS, Filecoin, or similar decentralized storage systems to manage geospatial data effectively.

• Perform code reviews and security audits to ensure the integrity of smart contracts and collaborate cross-functionally to integrate blockchain systems into Spexi’s platform.

• Troubleshoot and optimize smart contracts while staying current with blockchain trends and advancements.

• Create clear technical documentation and mentor team members through knowledge sharing and code reviews.

WHAT YOU BRING:

• 5+ years of experience in blockchain or software development, including writing EVM-compatible smart contracts and integrating backend services with blockchain.

• Proficiency in Solidity or similar languages for smart contract development.

• Familiarity in decentralized systems, cryptographic primitives (e.g., ZK proofs), and decentralized storage solutions (e.g., IPFS/Filecoin).

• Experience designing scalable, gas-efficient blockchain systems and working with Ethereum L2s or cross-chain bridges.

• Familiarity with Web3 infrastructure and private key management.

BONUS POINTS:

• Experience with decentralized governance models, airdrop mechanisms, and smart contract-driven decision-making.

• Knowledge of blockchain-based encryption schemes and decentralized decryption solutions.

• Experience designing and deploying App Chains tailored to specific use cases.
