1. About BitFit Labs
We are building enterprise cryptocurrency wallet that combines advanced Multi-Party Computation (MPC) Threshold Signature Scheme (TSS) with an integrated local DEX aggregation engine.
This hybrid solution provides institutional-grade security for asset custody while enabling seamless, low-latency token swaps without relying on third-party APIs.
Core Features:Â
- MPC TSS-based Wallet InfrastructureÂ
- Signature Scheme: 2/3 threshold signature distributionÂ
- Multi-chain Support: Bitcoin (BTC), XRP, Solana (SOL), EVM-compatibleÂ
- chains (Ethereum, BNB Chain, Avalanche, Arbitrum, Polygon, etc.), TRONÂ
- Hardware Integration: Support for Ledger and Trezor hardware walletsÂ
- Secure Key Management: TSS nodes distributed across isolatedÂ
- environments with HSM integrationÂ
- Local EVM DEX Aggregator EngineÂ
- Customized Geth Client: Modified Geth node with integrated DEX aggregator functionalityÂ
- On-chain Liquidity Indexing: Direct indexing of liquidity pools from multiple DEXs (Uniswap, SushiSwap, Curve, etc.)Â
- Local Swap Simulation: EVM-based swap simulation to calculate optimal routes, slippage, and pricingÂ
- Zero Third-Party Dependencies: All aggregation logic executed locally for privacy and reliabilityÂ
- Low-Latency Routing: Sub-second swap path discovery and execution
Â
2. Key Responsibilities
- MPC/TSS Wallet DevelopmentÂ
- MPC Protocol Implementation: Design and implement MPC (Multi-Party Computation) protocols in Golang to build highly available private key sharding and distributed signature servicesÂ
- Key Lifecycle Management: Develop secure end-to-end key lifecycle management systems including key generation, storage, recovery, and destructionÂ
- Threshold Signature Scheme (TSS): Implement TSS algorithms and secure multi-party computation protocols for 2/3 signature distributionÂ
- Multi-chain Integration: Build integration layers for multiple blockchain networks including Bitcoin (BTC), XRP, Solana (SOL), EVM-compatible chains (ETH, BNB, AVAX, ARB, POL), and TRONÂ
- Hardware Security: Integrate HSM (Hardware Security Module) solutions (YubiHSM, AWS CloudHSM, Azure Dedicated HSM) for enhanced securityÂ
- DEX Aggregator Engine DevelopmentÂ
- Custom Geth Development: Build and maintain a modified Geth client with integrated DEX aggregator functionality for local swap routingÂ
- Liquidity Pool Indexing: Develop on-chain data indexing pipelines to track liquidity pools from major DEX protocols (Uniswap V2/V3, Balancer, Curve, KyberSwap) directly from event logsÂ
- Pool State Management: Parse and decode DEX pool states including reserves, fees, and tick data via customized Geth RPC or direct state accessÂ
- Real-time Registry: Design and maintain a local pool registry that stays synchronized with the blockchain in real-timeÂ
- Reorg Handling: Implement robust logic to handle blockchain reorganizations with rollback and re-indexing capabilitiesÂ
- Swap Simulation: Collaborate on EVM simulation integration to test swap routes locally before executionÂ
- API Development
- Internal APIs: Build and maintain internal APIs to expose pool data, routing results, and token balances to frontend servicesÂ
- Wallet APIs: Develop secure APIs for wallet operations, transaction signing, and blockchain interactionsÂ
- Hardware Wallet Integration: Implement interfaces for Ledger and Trezor hardware wallet integrationÂ
- System ArchitectureÂ
- Microservices Design: Architect scalable, secure microservice architecture supporting both MPC wallet operations and DEX aggregationÂ
- Performance Optimization: Optimize high-performance data pipelines and real-time event processing systemsÂ
- Security Implementation: Implement security best practices across all wallet and trading operationsÂ
3. Requirements
- Experience: 5+ years of backend development experience, with 3+ years focused on Golang developmentÂ
- MPC/TSS Expertise: Deep understanding of MPC/TSS technology stack with actual production system development experienceÂ
- Cryptography: Strong knowledge of Elliptic Curve Cryptography (ECC), Zero-Knowledge Proofs, and Threshold Signature schemesÂ
- Blockchain Protocol Experience: Extensive experience in blockchain protocol layer development, familiar with at least Ethereum, Bitcoin, and Solana mainstream public chainsÂ
- Security Systems: Development experience in high-security systems (financial, payments, cryptocurrency)Â
- EVM Knowledge: Solid understanding of EVM, ABI encoding/decoding, and Ethereum event log parsing- Node Interaction: Experience interacting with Ethereum nodes (Geth, Erigon, or similar RPC clients)Â
- DEX Protocols: Familiarity with at least 2 major DEX protocols; Uniswap V2/V3 AMM math knowledge is requiredÂ
- Cloud Native: Proficiency with Docker, Kubernetes, and CI/CD cloud-native technology stacksÂ
- System Design: Excellent system design capabilities with experience designing scalable microservice architecturesÂ
- Data Pipelines: Experience building high-performance data pipelines and real- time event processing systems

Do blockchain developers work from home?
Yes, many blockchain developers work from home, especially in the current times where remote work has become more common due to the pandemic
The nature of blockchain development allows developers to work from anywhere in the world as long as they have a good internet connection and the necessary tools to do their work
In fact, many blockchain companies have fully remote teams and offer flexible work arrangements
This allows them to hire talented developers from all over the world without being limited by geographical location
However, it's important to note that not all blockchain development jobs are remote
Some companies may prefer to have their developers work on-site for security or other reasons
So, it's important to carefully read the job description and requirements before applying to ensure that you're comfortable with the work arrangements.
