Inco is building the confidentiality layer for blockchains through advanced encryption and secure-compute technologies. We’re building secure, scalable infrastructure that enables applications to process sensitive data while preserving confidentiality. We’re looking for a Senior Full Stack Engineer to join our team in Bangalore and help build a new product from the ground up.

You are a strong product engineer who can work across the stack and take full ownership of a production web application. You care deeply about performance, reliability, and user experience. You understand that getting a feature to work is only the beginning—you think about latency, failure modes, observability, scalability, edge cases, and how the system behaves under real-world load.

You are comfortable moving between frontend, backend, infrastructure, and external integrations to solve problems end-to-end. You thrive in fast-moving environments where requirements evolve quickly and engineers are expected to make strong technical decisions independently.

• Design, build, and maintain production-grade web applications.
• Own features end-to-end, from frontend interfaces to backend services and infrastructure.
• Build clean, maintainable, and scalable application architectures.
• Develop robust APIs and backend systems.
• Integrate third-party APIs and external infrastructure.
• Work closely with product, design, and protocol engineers to rapidly ship high-quality features.

• Take applications from early-stage prototypes to production-grade systems.
• Improve frontend performance, page load times, API latency, and responsiveness.
• Identify and eliminate performance bottlenecks across the stack.
• Build resilient systems that handle dependency failures gracefully.
• Implement caching, retries, fallbacks, idempotency, and failure recovery where appropriate.
• Ensure systems perform reliably under high traffic and rapidly changing workloads.

• Build applications that consume and display large amounts of frequently changing data.
• Design efficient Web Socket, streaming, polling, and event-driven architectures.
• Handle asynchronous state and race conditions across frontend and backend systems.
• Ensure data remains accurate, fresh, and consistent across application components.

• Build responsive and highly performant user interfaces using React, Next.js, and Type Script.
• Design scalable component and application-state architectures.
• Optimize rendering performance for complex, data-intensive interfaces.
• Build polished user experiences across desktop and mobile.
• Maintain a high standard for product quality and attention to detail.

• Build and maintain backend services supporting application logic and data processing.
• Design scalable APIs and data models.
• Work with databases, caching systems, queues, and event-driven services.
• Improve observability through logging, monitoring, tracing, and alerting.
• Debug complex production issues across application and infrastructure layers.

• Own major technical areas of the product.
• Make architecture and technology decisions with long-term maintainability in mind.
• Set a high bar for code quality, testing, documentation, and operational reliability.
• Conduct thoughtful code reviews and mentor other engineers.
• Proactively identify technical debt, scalability limitations, and reliability risks.
• Work closely with the founding and engineering teams in a highly iterative environment.

• 5+ years of software engineering experience.
• Strong production experience with…
