Senior Full-Stack Engineer — Solana Low-Latency Copy-Trading (Node.js + React)\n\nLevel: Senior\n\nRequired Hard Skills\n\n6+ years of Software Engineering experience\n\nStrong commercial experience with Node.js\n\nStrong experience with TypeScript (strict mode)\n\nStrong experience with React + TypeScript\n\nExperience with backend frameworks such as Nest.js, Express.js, Koa.js\n\nStrong understanding of React, including Hooks, Context, rendering behavior, and performance optimization\n\nStrong experience with state management tools such as Redux, MobX, Zustand, Recoil, or similar\n\nStrong software design knowledge: OOD, FP, design patterns, SOLID principles\n\nPractical hands-on experience with AI-assisted development tools such as Claude Code, Cursor, or similar\n\nExperience building low-latency, high-throughput, highly concurrent systems (real-time processing, hundreds+ of parallel operations)\n\nExperience working with external APIs and third-party data providers\n\nStrong understanding of RESTful APIs and GraphQL APIs\n\nAdvanced experience with SQL databases, especially PostgreSQL (transactions, locking, idempotency)\n\nExperience with database performance optimization, indexing, query optimization, and handling large datasets\n\nExperience with async / batch processing, scheduled jobs, background workers, queues, retries, throttling, and rate-limit handling\n\nHands-on experience with job / message queues such as BullMQ, Redis Streams, Kafka, RabbitMQ, Amazon SQS/SNS, or similar\n\nExperience with Docker and CI/CD processes\n\nExperience with AWS or similar cloud platforms (GCP, Azure)\n\nExperience building systems that require data validation, consistency checks, idempotency, and crash-recovery safeguards\n\nUnderstanding of trading, fintech, blockchain, or data-intensive financial systems\n\nKnowledge of Agile development practices, preferably SCRUM\n\nProficient understanding of Git\n\nRequired Blockchain / Solana / Copy-Trading Experience\n\nSolid understanding of Solana internals: transactions, instructions, accounts, blocks/slots, commitment levels (processed / confirmed / finalized), blockhash lifetime, and reorg handling\n\nHands-on experience with low-latency Solana execution / trading bots — landing transactions competitively (same-slot / “block-0”), priority fees, and MEV-aware submission\n\nExperience with real-time Solana data streaming: Yellowstone gRPC (Triton Dragon’s Mouth / Helius LaserStream) and/or shred-level feeds such as Jito ShredStream (awareness of DoubleZero Edge a plus)\n\nExperience with transaction submission & landing infrastructure: Jito (Block Engine / bundles / tips), Helius Sender, SWQoS (stake-weighted QoS), and specialist senders (0slot / Nozomi / bloXroute)\n\nExperience with blockchain data / RPC providers such as Helius, Triton, QuickNode, Alchemy, or similar, including multi-provider failover and rate-limit handling\n\nFamiliarity with Pump.fun / PumpSwap: bonding-curve mechanics, AMM pricing, and building instructions from an on-chain IDL\n\nUnderstanding of trading metrics: entry/exit, market cap, slippage, hit rate, P&L, and per-position / portfolio risk\n\nExperience with crypto trading platforms, copy-trading systems, DEX / on-chain execution, or wallet automation\n\nExperience with secure key management at scale (HD wallet derivation, in-memory signing, secrets isolation) and capital-isolation / fail-safe design\n\nExperience with trading systems, bots, DeFi or high-throughput financial systems strongly preferred.\n\nWould Be Great\n\nExperience writing performance-critical services in Rust (a native signing / execution hot-path is on the roadmap)\n\nExperience running leader-proximate bare-metal / colocation (Frankfurt / Amsterdam) and host/network tuning for latency\n\nExperience with Jito bundles, durable nonces, and transaction idempotency / reconciliation against chain\n\nExperience integrating CEX withdrawal APIs (Binance / MEXC / KuCoin) for programmatic funding\n\nExperience with observability tools such as Prometheus, Grafana, Datadog, Sentry, ELK, OpenTelemetry, or similar\n\nExperience designing systems with fallback providers, retry logic, throttling, circuit breakers, and API-usage monitoring\n\nExperience building HFT / MEV / market-making or other latency-sensitive financial systems\n\nResponsibilities\n\nBuild and maintain full-stack features for ARES, a private copy-trading bot for the Pump.fun / Solana ecosystem\n\nDesign and implement the block-0 execution engine: real-time target detection, pre-trade gating, and same-slot buy submission across multiple routes\n\nIntegrate low-latency detection (Yellowstone gRPC / Jito ShredStream) and submission (Helius Sender / Jito bundles / SWQoS / specialist senders) with multi-provider failover\n\nBuild the wallet lifecycle & custody layer: provisioning isolated child-wallet pairs per task, funding, profit skimming, and drain-to-vault — under strict capital isolation\n\nImplement position & exit management (rule-driven take-profit, sell-after-inactivity, chase-sells) and the per-task kill-switch / risk protection\n\nImplement idempotency, durable intent, and crash / reorg reconciliation so no trade is ever double-executed at scale\n\nBuild the operator dashboard (React): copy-task configuration, live task & health monitoring, controls (pause / resume / kill), and global safety limits\n\nConstruct Pump.fun bonding-curve buys from the live IDL, with graduation gating and pre-trade safety checks\n\nDesign controlled concurrency, batching, throttling, retries, and rate-limit handling to sustain 1,000+ tasks / ~2,000+ wallets\n\nOptimize the detect → decide → sign → submit → land path to maximize block-0 landing rate (KPI #1) and uptime / failover (KPI #2)\n\nImplement secure key management (HD derivation, in-memory signing) and secrets handling; enforce fail-safe defaults and an explicit kill switch on every execution path\n\nCollaborate with product, engineering, and domain stakeholders on trade-offs across latency, cost, and reliability; participate in architecture discussions\n\nWrite clean, secure, maintainable, well-tested code (unit + e2e); conduct code reviews; maintain documentation; support production readiness\n\nMonitor system reliability, execution latency and landing rate, provider health, and data quality\n\nEnglish Level\n\nUpper-Intermediate or higher","description_format":"text","description_chars":6288,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["DeFi","Freelance
