About the Role:We are seeking a talented and driven Frontend Engineer to shape the user experience of a cutting-edge no-code platform for building custom LLM applications. This role offers an exciting opportunity to take full ownership of the frontend, crafting sleek, intuitive interfaces and ensuring seamless backend integration.

You’ll work in a fast-paced startup environment, creating powerful, scalable, and secure solutions to redefine how users interact with LLM-powered tools like RAG, SQL-to-text, and structured outputs.

Roles and Responsibilities:

• Design and deliver pixel-perfect, reactive UIs that users love.

• Take full ownership of the frontend, iterating rapidly and independently.

• Leverage frameworks and libraries powering GenAI platforms such as ChatGPT, Perplexity, and Claude.

• Optimize API data structures using JSON schemas, pagination, filtering, sorting, and indexing for large datasets.

• Build and maintain RESTful and WebSocket APIs using robust version control and resource-based architecture.

• Develop and maintain web applications using modern frameworks like Vue.js/Nuxt.js or React.js/Next.js.

• Implement security best practices, including input validation, OAuth/JWT authentication, and OWASP standards.

• Collaborate with backend teams to design and implement scalable APIs adhering to RODL principles.

Job Requirements:

• Proven ability to independently ship significant products or features with measurable impact.

• Expertise in Python-based API frameworks like FastAPI.

• 5–10 years of experience in frontend engineering (3+ years considered for exceptional candidates).

• Prior experience at fast-paced Series B+ startups (e.g., Stripe, Scale AI, Databricks, DataRobot).

• Demonstrated ability to build complex user interfaces at scale with pixel-perfect implementation from Figma designs.

• Expert-level skills in Vue.js (preferred) or React, with proficiency in TypeScript and design systems.

• Proficiency in SQL (MySQL) and NoSQL (e.g., DynamoDB, DataStore, Redis) databases.

• Experience with CI/CD pipelines, preferably on AWS/GCP with Docker.

• Strong Git workflows, including version control using GitHub.

• "Grinder" mentality – willingness to work long hours and thrive in a startup environment with rapid changes and uncertainty.

• U.S. Citizen or Permanent Resident.

Nice to Have:

• Deep understanding of API design, particularly in OpenAI/Stripe-style integrations.

• Experience with both RESTful and WebSocket (Socket.io) APIs.

• A strong portfolio demonstrating past products or projects.
