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 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.
