Company: Riza (https://riza.io) is a seed-stage startup based in San Francisco, founded by experienced second-time founders (ex-Twilio, Stripe, Retool). We are a small team of 3 working out of a converted warehouse. We provide secure, high-performance isolated runtimes (WebAssembly, V8, microVMs) for executing untrusted code, particularly code generated by LLMs. Our Code Interpreter API handles billions of executions monthly for AI-native companies.

Role: We are looking for a versatile Full-Stack Engineer to join our founding team. You will be responsible for building user-facing features, including our account dashboard, and potentially contributing to our backend API. This role requires bridging the gap between frontend user experience and backend functionality.

Responsibilities:
- Design, develop, and maintain the Riza account dashboard using React, TypeScript, and Go.
- Build and maintain backend services supporting the dashboard and potentially other features, using Go and PostgreSQL.
- Work closely with the team to design and implement user interfaces and user experiences.
- Integrate frontend components with backend APIs.
- Contribute to the development of our main API (Go/Postgres) as needed.
- Write clean, maintainable, and well-tested code across the stack.
- Participate in product discussions and feature planning.

Technical Skills Required:
- Strong proficiency in frontend development with React and TypeScript.
- Solid experience in backend development, preferably with Go.
- Experience with relational databases, specifically PostgreSQL.
- Familiarity with state management libraries (e.g., Redux, Zustand) and modern frontend tooling.
- Experience building and consuming RESTful APIs.
- Understanding of web fundamentals (HTML, CSS, JavaScript).
- Experience with testing frameworks for both frontend and backend.

Ideal Candidate:
- Enjoys working across the entire technology stack, from UI to database.
- Is comfortable in a fast-paced, early-stage startup environment and taking ownership.
- Has a good eye for user experience and product design.
- Communicates effectively and collaborates well with a small team.
- Is eager to learn and adapt to new technologies and challenges.
- Experience with LLM APIs (Anthropic/OpenAI) or building developer tools is a plus.
