About the company

The company 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.

Who You Are

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.

Responsibilities

Full-Stack Engineering

• 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.

Performance & Reliability

• 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.

Real-Time Systems

• Build applications that consume and display large amounts of frequently changing data.

• Design efficient WebSocket, 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.

Frontend Engineering

• Build responsive and highly performant user interfaces using React, Next.js, and TypeScript .

• 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.

Backend Engineering

• 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.

Engineering Ownership

• 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.

Required Experience

• 5+ years of software engineering experience .

• Strong production experience with TypeScript and React .

• Experience building and operating backend services.

• Strong understanding of web application architecture, APIs, databases, and caching.

• Proven experience improving the performance, reliability, and scalability of production applications.

• Strong understanding of asynchronous systems, concurrency, networking, and application state.

• Experience building applications that process real-time or frequently changing data.

• Experience debugging complex issues across frontend, backend, infrastructure, and external dependencies.

• Strong product instincts and attention to detail.

• Ability to independently own technically complex projects from architecture through production.

• Comfortable working in an early-stage startup environment with significant ambiguity and ownership.

• Based in Bangalore or able to work regularly from our Bangalore office.

Preferred Qualifications

• Experience building high-performance financial, trading, crypto, or data-intensive applications .

• Experience with Web3 or blockchain applications.

• Experience integrating wallets, blockchain RPCs, indexers, or onchain infrastructure.

• Experience with WebSockets, streaming systems, or event-driven architectures .

• Experience with Postgres, Redis, queues, and caching infrastructure.

• Experience with Next.js and Node.js.

• Experience designing highly available systems with strong observability and monitoring.

• Experience with CI/CD, cloud infrastructure, and production operations.

• Familiarity with application and infrastructure security.

• Experience at an early-stage startup where you owned significant parts of a product.

What We Value

We care about engineers who combine strong technical fundamentals with excellent product judgment. The strongest candidates have taken systems beyond the prototype stage and made them fast, reliable, scalable, and maintainable in production. We’re looking for someone who takes ownership, dives deeply into difficult problems, and cares about building products that users can rely on.
