Full Stack Developer

About the Role

As a Full Stack Developer, you will own features end-to-end from designing and building responsive, performant React frontends to architecting robust Node.js APIs and working with relational and non-relational databases. You will ship code that reaches real users and take responsibility for its quality, reliability, and performance in production.

We are looking for engineers who are as comfortable debugging a slow SQL query as they are polishing a UI interaction, and who take pride in building systems that are simple, correct, and maintainable.

In This Role, You Will

• Design and build full-stack features across React-based frontends and Node.js (or similar) backends, owning them from spec to production deployment.
• Architect and develop RESTful APIs and GraphQL services that are performant, secure, and well-documented.
• Design and optimize database schemas, queries, and indexes for PostgreSQL and/or MongoDB at scale.
• Build and maintain reusable, accessible, and responsive UI components using React and TypeScript.
• Integrate third-party services including payment gateways, authentication providers, cloud storage, and notification systems.
• Write clean, well-tested code with meaningful unit, integration, and end-to-end tests using tools like Jest, Vitest, or Playwright.
• Participate actively in code reviews, providing and receiving feedback that raises the quality bar for the entire team.
• Collaborate with DevOps to manage cloud infrastructure on AWS or GCP, including containerized deployments using Docker and Kubernetes.
• Monitor production systems, investigate incidents, and implement lasting fixes not just hotpatches.
• Contribute to technical architecture decisions and help define best practices, coding standards, and engineering processes as the team grows.

You Might Thrive in This Role If You

• Have 2–6 years of experience building and shipping production web applications across both frontend and backend.
• Are fluent in TypeScript and have strong opinions (loosely held) about clean, maintainable code architecture.
• Are comfortable owning a feature completely writing the database migration, building the API, and shipping the UI without needing to hand off across teams.
• Understand how systems fail in production and proactively build for reliability, observability, and graceful degradation.
• Have a genuine interest in user experience and hold a high personal bar for the interfaces you ship, not just the logic behind them.
• Thrive in fast-moving environments where requirements evolve, priorities shift, and the right answer isn't always obvious.
• Enjoy making technical decisions choosing the right data structure, the right abstraction, the right tradeoff and can articulate the reasoning clearly.
• Are curious about AI and have explored or are excited to build products that integrate large language models or AI APIs into real applications.
• Communicate well in writing and in meetings, and keep your teammates informed without over-engineering your processes.

Bonus If You Have

Experience with Next.js or a similar server-side rendering framework.
Familiarity with event-driven architectures using message queues such as Kafka, RabbitMQ, or AWS SQS.
Hands-on experience with infrastructure-as-code tools such as Terraform or AWS CDK.
Knowledge of web performance optimization — Core Web Vitals, lazy loading, code splitting, and caching strategies.
Experience integrating or building with AI/LLM APIs such as OpenAI, Anthropic, or Gemini.
Contributions to open-source projects or a public portfolio of work you're proud of.
Exposure to micro-service or micro-frontend architectures in a production environment.

How to Apply

Send your resume, links to projects or repositories you've shipped, and a short note about a technical decision you made that you're proud of — and why you made it.
