Role

Who you are

Experience: 3+ years of experience as a front-end engineer utilizing JavaScript/TypeScript and the React library
AI-Assisted Workflow: Daily practical experience with AI-assisted or agentic development tools, with the engineering judgment needed to audit and refine AI outputs
Modern Engineering Practices: Familiarity with TDD principles, clean architecture concepts, and consuming APIs (e.g., GraphQL)
Mindset: An independent, critical thinker who thrives in collaborative, small-team environments and values continuous feedback

Desirable

Backend development experience in Java or Kotlin (ideally Spring Boot)
Understanding of microservices, database concepts (RDBMS/PostgreSQL), and event-driven architectures (Kafka)
Familiarity with containerization (Docker) or cloud deployments (AWS/Kubernetes)

What the job involves

Feature Development: Build, test, and optimize highly scalable, user-oriented features for our client-facing web application
Full Stack Adaptability: Take ownership of domain software, contributing to our event-driven microservices platform when backend support is needed
AI Engineering: Leverage agentic coding tools (e.g., Claude Code) across the full development lifecycle, reviewing and hardening AI-generated outputs to maintain rigorous quality standards
