Blockchain / Data Engineer

About DeFi Orbit

Simplifying multi-chain DeFi portfolio management with intelligent analytics and real-time tracking

DeFi Orbit is at the forefront of blockchain data infrastructure, building high-performance systems that power real-time DeFi analytics and applications. We're looking for exceptional engineers who combine deep blockchain knowledge with data engineering expertise.

The Role

We're seeking a highly skilled Full-Stack Blockchain/Data Engineer who thrives at the intersection of blockchain technology and data engineering. You'll architect and build high-throughput indexers, real-time data pipelines, and conduct deep research into various DeFi protocols across multiple blockchain ecosystems (EVM, Solana, SUI).

This is a role for engineers who want to work on complex technical challenges at scale, diving deep into blockchain infrastructure while building production-grade data systems.

What You'll Do

• Design and build high-throughput blockchain indexers for multiple chains (EVM, Solana, SUI)
• Architect real-time data pipelines processing millions of blockchain events
• Research and integrate various DeFi protocols (Uniswap, Orca, Aave, and others)
• Build full-stack features from UI to database, owning the complete technical stack
• Design schemas and scale databases (PostgreSQL, ClickHouse) for blockchain data
• Develop microservice-based applications using Kafka and Redis
• Handle complex scenarios like chain reorganizations, backfills, and data quality assurance
• Optimize data ingestion and processing for performance and reliability

Required Qualifications

Experience:

• 5-8 years of deep technical experience
• Minimum 3 years of proven DeFi/blockchain experience
• 5+ years overall software engineering experience

Blockchain Expertise:

• Deep understanding of blockchain internals: nodes, mempools, RPCs
• Expert knowledge of smart contracts, logs/traces, and event models
• Experience working with multiple chains (EVM, Solana, SUI)
• Understanding of DeFi protocol mechanics and intrinsics

Data Engineering:

• Large-scale data ingestion and processing
• Change Data Capture (CDC) systems
• Backfill strategies and implementation
• Blockchain reorganization handling
• Data quality frameworks and monitoring

Technical Stack:

• Fluent in TypeScript (this is critical)
• Strong experience with Next.js and Nest.js
• Full-stack capability - comfortable across frontend and backend
• Expert-level PostgreSQL (schema design, scaling, management)
• Experience with ClickHouse database
• Proven ability architecting with Kafka and Redis
• Strong understanding of data structures and algorithms

Soft Skills:

• Ability to own features end-to-end
• Strong research and analytical capabilities
• Excellent problem-solving skills
• Clear communication and documentation

Bonus Qualifications

• Experience with Subsquid or TheGraph
• Deep understanding of AMM and lending mathematics
• Solana or SUI smart contract development
• Experience with other blockchain data indexing solutions

What Makes You Stand Out

• You've built production blockchain indexers or data pipelines
• You can explain complex DeFi protocols and their data models
• You have experience optimizing high-throughput distributed systems
• You've handled petabyte-scale blockchain data
• You contribute to open-source blockchain projects
