Job Description

About the role

We are looking for a Senior Fullstack Engineer with deep expertise in React, Node.js, and TypeScript to help shape the architecture, performance, and quality of our products across the stack. We're a fast-paced company building high-traffic SaaS products used by many people at once. This role is highly hands-on: you'll build, optimize, and scale features from the database to the UI, take part in design and architecture decisions, and play a key role in code reviews and technical standards. AI-assisted development is at the core of how we work, so strong, hands-on experience with it is mandatory. We're looking for someone who takes ownership, holds themselves accountable for outcomes, and pushes things forward.

What you'll do

Use AI-assisted development (Cursor, Claude, agents) as a core part of your daily work: planning, coding, testing, reviewing, and debugging
Help shape and improve our AI-driven engineering workflows, including prompts, agent setups, rules, and best practices the whole team can use
Keep quality high in AI-generated code through thorough review, testing, and clear architectural boundaries
