This role requires close collaboration with other engineers, non-technical departments, and teams working on integrations and data-heavy workflows - strong communication skills and c-level thinking are key.

What You’ll Work On

- Build and extend backend APIs, services, and async workers

- Implement frontend features using Next.js (React, hooks, state management)

- Integrate with internal and external systems through REST/webhook APIs

- Work with other developers to define API contracts and data flows

- Handle retries, scheduling, idempotency, and monitoring logic

- Contribute to system design and make architecture-level suggestions

Requirements

- 5+ years of full-stack development experience

- Strong backend skills in Node.js (with TypeScript)

- Production experience with Next.js

- Strong SQL skills and understanding of schema design and advanced queries.

- Comfortable with async programming, background jobs, and task queues (e.g., BullMQ, RabbitMQ, or custom)

- Experience collaborating with other engineers in a structured, asynchronous environment

- Intermediate or higher English (for tech specs, docs, and team syncs)

Mindset & Communication

- Ownership mentality, balancing urgent deliverables with long-term architectural vision

- Organized and reliable, able to prioritize critical tasks without sacrificing code quality

- Research-oriented approach: you evaluate new tools and patterns but focus on practical implementation

- Strong communicator who can collaborate effectively with product, design, and operations team

Bonus Points

- Experience working on internal platforms or large-scale operations tools

- Understanding of CI/CD and Docker-based deployment workflows

- Experience with queue-based job execution or scheduling logic

About the Role
 

We’re building an in-house batch payout and reconciliation platform for ERC-20 and TRC-20 tokens. You’ll own the end-to-end architecture - from hot-wallet key management and bulk on-chain transfers to monthly SLA reporting - supporting up to 10,000 concurrent transactions.

Key Responsibilities:

- Architect and build a high-throughput batch payout engine in Node.js, handling ERC-20 & TRC-20 token transfers

- Integrate with self-custodied hot wallets; securely manage private keys (AWS KMS, HashiCorp Vault, HSM, etc.)

- Implement nonce management, gas optimization (EIP-1559), and on-chain batch-transfer contracts

- Develop reconciliation logic using both on-chain data and off-chain data from CEXs/DEXs and Oracles

- Design retry strategies, error handling, and idempotent workflows for failed or reverted transactions

- Monitor system health, log all activities, and produce monthly SLA reports, tracking success rates, confirmation times, and uptime

Required Qualifications:

- 5+ years professional Node.js experience

- Deep familiarity with blockchain protocols - ERC-20 & TRC-20 standards, gas/bandwidth/resource models

- Hands-on experience with web3.js, ethers.js, tronweb, and CCXT

- Proven track record designing high-throughput systems with precise nonce and concurrency control

- Solid understanding of cryptographic key management best practices (hot wallets, KMS/Vault, HSM, multi-sig)

- Ability to troubleshoot complex blockchain issues - gas volatility, reorgs, token approvals, API rate limits, TRON resource constraints.

Mindset & Communication:

- Ownership mentality: you balance urgent deliverables with long-term architectural vision

- Organized and reliable: you prioritize critical tasks without sacrificing code quality

- Research-oriented approach: you evaluate tools and patterns, but focus on what works in practice

Nice-to-Have

- Experience writing or integrating batch-transfer smart contracts in a Node.js environment (e.g. OpenZeppelin MultiSend)

- Knowledge of The Graph subgraphs for DEX data analytics

- Prior work in crypto exchange integrations or fintech reconciliation systems
