About DeFi Orbit

DeFi Orbit is building the next-generation portfolio management platform for active DeFi investors. Our research with 25+ professional DeFi users revealed that 70% still rely on manual spreadsheets to track positions across chains - we're solving this with sophisticated multi-chain data infrastructure.

We have strong product-market fit validation, a growing waitlist of 390+ users, and are backed by strategic partnerships with leading DeFi communities.

The Challenge

We need a blockchain data infrastructure specialist to architect and build our core data processing pipeline. This role involves creating sophisticated systems that aggregate, normalize, and analyze DeFi position data across multiple chains and protocols in real-time.

What You'll Build

Core Data Infrastructure Components:

• Backfill Engine: Historical blockchain data processing and position reconstruction
• Live Listener Engine: Real-time event monitoring across EVM and Solana chains
• Normalized Events DB: Chain-agnostic event storage and indexing system
• LP State Engine: Current position state calculation and maintenance
• LP Metrics Engine: Performance analytics (APR, impermanent loss, benchmarking)
• API Layer: GraphQL/REST APIs serving frontend applications

Protocol Integrations (Phase 1):

• EVM: Uniswap V3, Aave V3, Aerodrome
• Solana: Orca, Raydium, Kamino Finance

Technical Requirements

Must-have experience:

• 3+ years building blockchain data processing systems at scale
• Deep DeFi protocol knowledge: Concentrated liquidity mechanics, lending protocols, yield calculations
• Multi-chain expertise: EVM chains (Ethereum, Base, Arbitrum) + Solana
• Data infrastructure: Event processing, state management, real-time pipelines
• Backend proficiency: Node.js/TypeScript, PostgreSQL, Redis

Preferred Qualifications:

• Experience with The Graph Protocol, custom indexers, or subgraph development
• Rust development for high-performance data processing
• Knowledge of Solana program architecture and account parsing
• Previous work on portfolio tracking or DeFi analytics platforms
• Experience with WebSocket management and real-time data streaming
• AWS infrastructure: RDS, EC2, Lambda, event-driven architectures

What Makes This Role Unique

Technical Complexity:

• Build systems processing millions of blockchain events efficiently
• Implement complex DeFi calculations (impermanent loss, concentrated liquidity math)
• Design cross-chain data normalization for consistent user experience
• Handle chain reorganizations, finality, and data consistency challenges

Business Impact:

• Technical decisions affect platform scalability and user experience
• Work with paying customers from day one (subscription model)
• Shape the architecture for multiple future DeFi Orbit products
  

Team Culture:

• Small, focused team: Work directly with founder and the founding team
• User-driven development: Features based on extensive user research, not assumptions
• Quality over speed: We ship when it's right, not when it's fast
• Remote-first: Core hours overlap with MST (Mountain Standard Time)

Compensation & Equity

• Competitive salary: Based on experience and location
• Meaningful equity: Early-stage equity with significant upside potential
• Performance-based increases: Tied to technical milestones and platform growth
• Bootstrap-conscious: We're efficient with resources but competitive on talent

How to ApplyWe want to see:

GitHub profile showcasing blockchain data work or DeFi protocol interactions

Brief technical writeup (500-1000 words) on how you'd approach building our Normalized Events DB for cross-chain data

Examples of complex data processing systems you've built (can be web2 if relevant)

Application Process:

Technical questionnaire (15 minutes)

Architecture discussion (45 minutes) - we'll discuss our current progress and technical decisions

Technical challenge (4-6 hours, paid) - small data processing task relevant to our stack

Final interview (1 hour) - cultural fit and compensation discussion
