Senior Full-stack Engineer (Backend-focused)

About the Role

We are looking for a frontend-focused engineer who values high-performance user interfaces and technical ownership. While your expertise lies in React and Next.js, you are a full-stack builder who is comfortable writing the APIs, Lambdas, and database queries needed to power the features you build.

What You'll Be Doing

• Build High-Performance Interfaces: Architect and maintain complex, real-time dashboards using Next.js and Tailwind CSS. You'll focus on rendering high-velocity transaction data with low latency and high reliability.

• Bridge the Stack: Design and implement the backend logic and APIs required to feed the frontend. You own the feature from the UI down to the data source.

• Manage Real-Time State: Handle the complexities of mirroring on-chain data and legacy transaction flows in the UI, ensuring the state is consistent, reactive, and optimized for performance.

• Define Infrastructure as Code: Use SST (built on Pulumi) to manage your frontend hosting, API gateways, and cloud resources, ensuring version control and rollback safety.

• Write Clean, Type-Safe Code: Leverage TypeScript across the entire stack to ensure end-to-end type safety. You value maintainable patterns and code that serves as documentation for the team.

• Optimize for Observability: Build with a focus on how the frontend performs in production — addressing race conditions, handling async data failures gracefully, and monitoring user-facing latency.

• Push the Team Forward: You unblock others, participate in code reviews, and leave the codebase better than you found it. You prioritize long-term system health over quick fixes.

About You

• Frontend-First: Your expertise is in the user experience, but you are technically self-sufficient in the backend and can navigate the full application lifecycle autonomously.

• Hands-on and Execution-Focused: You like to get things done. You think before you build, but you don't overthink.

• Detail-Oriented but Pragmatic: You care about edge cases and data integrity, but you know when it's time to ship and iterate.

• Performance-Obsessed: You care about Core Web Vitals, efficient state management, and the lifecycle of a request from the UI to the database.

• Casino/Web3 Alignment: You have direct experience in the casino and are excited by the unique challenges of building auditable, on-chain transaction systems.

• Startup-Ready: You're comfortable with speed, ambiguity, shifting priorities, and constant iteration. You move fast, but not carelessly.

Tech Stack

• Frontend: Next.js (App Router), Tailwind CSS, React

• Runtime/Language: Bun/Node.js, TypeScript

• Cloud/Infra: AWS, SST (Pulumi), Event-driven architecture (EventBridge, Lambda)

• Database: PostgreSQL
