• Collaborate with the design team to implement responsive and intuitive interfaces.
• Integrate LLM‑powered capabilities (OpenAI, Gemini, Anthropic) to improve pricing, operations, and customer support.
• Develop intuitive interfaces for LLM-driven functionalities (e.g., chatbots, content generation).
• Implement and maintain real-time features using WebSockets and similar technologies.
• Develop robust observability: structured logging, distributed tracing, and alerting.
• Participate in code reviews within our repo and help level up peers.
• Collaborate cross‑functionally on system design and product discovery in an async‑first workflow.
• Write clean, well‑documented, and thoroughly tested code.

• Familiarity with Redis for caching and session management
• Experience with implementing LLM-powered features in web and mobile applications
• Familiarity with best practices for LLM-driven UX design
• Experience with monorepo structures and build systems (we use Yarn, Nx, and Turbo)
• Understanding of responsive design principles
• Familiarity with cloud services, preferably GCP
• Excellent problem-solving skills and attention to detail
• Strong communication skills and ability to work in an async environment
• Experience with version control systems (Git) and CI/CD pipelines

Bonus Points

• Experience with GraphQL.
• Familiarity with containerized environments (Docker, Kubernetes).
• Knowledge of event-driven architectures and message brokers (e.g., Kafka).
• Understanding of serverless architectures.
• Experience with real-time communication protocols (WebSockets, Socket.io).
• Contributions to open-source projects.

Our Tech Stack

• Backend: Node.js, TypeScript, Fastify
• Database/Cache: PostgreSQL, Redis, Kafka
