Founding Senior Backend Engineer

Founding Senior Backend Engineer (3-Month Contract | Immediate Start) Location: Hyderabad, India (Hybrid preferred) Contract: 3 months (with high potential to convert to full-time) Start: Immediate About the Role We’re looking for a Founding Senior Backend Engineer to design and build our core wallet and trading infrastructure from the ground up. You’ll own the backend architecture that powers our flagship crypto-fintech app from wallet services and trade execution to yield strategies and AI-driven trading policies. You’ll work closely with mobile engineers (React Native/Flutter), product, and design to ship a platform that is secure, performant, and ready to scale from 0 → 1. This is a high-ownership role where your decisions will define the technical foundation of the product. What You’ll Do - Architect and build core backend services for wallet management, balances, transactions, and accounting/ledgering. - Design and implement trading infrastructure: - Order routing and execution - Integration with liquidity providers and exchanges - Slippage, fees, and risk constraints - Implement yield and trading strategies as robust, configurable services (DCA, yield products, automated rebalancing, etc.). - Build AI-driven policy and execution layers: - Define policy engines that can evaluate signals and constraints - Safely trigger, simulate, and execute trades based on AI-driven or rules-based strategies - Design secure APIs consumed by mobile and web clients. - Own data persistence and performance: relational databases, caching layers, and event-driven flows. - Ensure security, reliability, and observability: - Logging, metrics, alerting - Rate limiting, auth, and permissions - High availability and resilience - Collaborate closely with a global team (North America & India) across product, design, and mobile. - Play a key role in architecture, technical roadmap, and product decisions as a founding engineer. Requirements - 3+ years of professional backend engineering experience (ideally in product-focused teams). - Proven experience designing and shipping production backend systems (microservices or modular monoliths). - Strong in TypeScript/Node.js and/or Go/Rust, with solid fundamentals in system design and distributed systems. - Hands-on experience with REST (and/or GraphQL) APIs, Relational databases (e.g., Postgres), Caching and state management (Redis or similar) - Strong understanding of performance, scalability, and reliability in backend systems. - Excellent debugging, problem-solving, and architectural skills. - Comfortable working in fast-moving, early-stage environments with high autonomy. - Immediate availability to join and start building. - Willingness to collaborate with a global team in North America (overlapping hours where needed). Bonus Skills - Experience working on FinTech or Crypto products (exchanges, wallets, brokerages, payment apps). - Familiarity with wallet security, key management, and authentication flows (e.g., OAuth, JWT, biometrics integration via APIs). - Experience with trading systems, market data, or yield strategies. - Knowledge of AI/ML or policy engines used for decision-making and automation. - Experience with testing, CI/CD, and cloud infrastructure (AWS/GCP/Azure, containers, Kubernetes, etc.). - Comfort collaborating with frontend/mobile teams and product in TypeScript-heavy environments. Why This Role Matters This is an opportunity to join at the ground floor as a founding backend engineer and shape the technical DNA of a next-generation crypto product. You’ll: - Define the core wallet and trading infrastructure. - Architect systems that AI-driven strategies and millions of future users can rely on. - Have real ownership, autonomy, and impact on how the product works under the hood. If you love building secure, high-performance systems, enjoy thinking in terms of primitives and platforms rather than one-off features, and want to help power a product that could serve millions of users — this role is for you.
