<Startale Group> is a blockchain-focused technology company building an integrated web3 ecosystem that includes Soneium (a creator platform), Strium (a Layer-1 blockchain for tokenized securities and RWAs), Startale App (an all-in-one superapp), and Startale USD, a compliant stablecoin. The company develops developer tools, an Ethereum L2, and partners with institutional firms to enable on-chain real-world assets, payments, and digital economy experiences.

📋 Description

• Take ownership of backend architecture and implementation across multiple products within the Startale ecosystem. • Design, build, and maintain scalable production APIs and backend services used by customer-facing applications. • Build and operate high-performance distributed systems capable of serving large user bases and handling significant production traffic reliably. • Design backend systems with strong focus on scalability, fault tolerance, reliability, and long-term maintainability. • Build and maintain data pipelines, background workers, asynchronous processing systems, and event-driven architectures. • Build and maintain blockchain integrations and indexing systems that ingest, process, and serve on-chain data to internal services and user-facing applications. • Design efficient database schemas, optimize complex queries, and ensure long-term scalability of data storage systems. • Work across both Web2 and Web3 backend infrastructure, integrating traditional backend systems with blockchain protocols and decentralized infrastructure. • Diagnose and solve complex production issues, performance bottlenecks, reliability problems, and scaling challenges. • Build systems with strong observability, monitoring, alerting, and operational tooling. • Continuously improve backend architecture, deployment pipelines, system reliability, and engineering practices. • Move quickly, make sound technical decisions independently, and take ownership of delivering production-ready systems.

🎯 Requirements

• Extensive experience building and operating production backend systems in modern engineering environments. • Strong proficiency in TypeScript and modern backend frameworks (NestJS, Fastify, Express, or similar). • Strong understanding of backend architecture, API design, service-oriented architecture, and distributed systems design. • Ability to independently design and deliver complex backend systems with minimal oversight. • Proven track record building and operating backend systems serving large numbers of users in production environments. • Experience designing systems that operate reliably under high traffic, heavy workloads, and demanding production conditions. • Strong understanding of performance optimization, scalability bottlenecks, concurrency, fault tolerance, and infrastructure reliability. • Experience operating systems where uptime, consistency, and reliability directly impact end users. • Strong operational mindset and experience handling production incidents and scaling challenges in live systems. • Deep expertise with PostgreSQL, including schema design, indexing, query optimization, migrations, and production database management. • Experience building systems that process large amounts of structured or event-driven data. • Strong understanding of observability, logging, monitoring, and service health management. • Experience building backend systems for modern Web2 applications. • Experience integrating with blockchain infrastructure, node APIs, smart contracts, or decentralized protocols. • Familiarity with blockchain indexing systems, event processing pipelines, or other on-chain data infrastructure. • Good understanding of wallet architecture, transaction lifecycle, signing flows, and blockchain data models. • Familiarity with DeFi protocols and blockchain-based financial applications, either as a developer or an advanced user.

🏖️ Benefits

• Competitive compensation • Ownership opportunities • Direct role in shaping the future of Web3 products
