Blockchain / Data Engineer at DeFi Orbit

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
