You’ll join one of our product teams, taking end-to-end ownership of features from database schema to UI component.

• Design and implement features end-to-end, from robust backend services and APIs in Java/Kotlin and Spring Boot to polished, responsive user interfaces in Angular.
• Own the full lifecycle of features - database schema to UI component - while maintaining high code quality standards and contributing to architectural decisions.
• Work within agile product teams to deliver high-quality features, participate in code reviews, and contribute to technical discussions across both backend and frontend.
• Partner with designers and product managers to translate requirements into complete, working solutions.
• Tackle complex technical problems that span the full stack, propose innovative solutions and continuously improve our development practices, tooling, and user experience.
• Leverage AI coding assistants and tools to accelerate development velocity across the full stack.
• Help establish and refine AI-assisted development workflows, prompting strategies, and best practices for the team.
• Evaluate and adopt emerging AI tools that improve code quality, testing, and developer productivity.
• Contribute to a culture where AI is a natural part of the engineering workflow, not an afterthought.

Qualifications

• A genuine desire to work across the entire stack, not just tolerance for it.
• Deep expertise in either Java/Kotlin and Spring Boot or Angular and TypeScript, with demonstrated hands-on experience in the other.
• Strong understanding of OOP, functional programming, software design principles, and modern architecture patterns.
• Ability to write clean, performant, and maintainable code in both backend and frontend contexts.
• Demonstrated ability to analyze and solve complex technical problems that span multiple layers of the system.
• Strong commitment to code quality, testing practices, and software development best practices across the stack.
• Ability to clearly communicate technical concepts and decisions, participate effectively in code reviews, mentor other engineers, and contribute to a positive team culture.
• Ability to understand system architecture and how frontend and backend components interact, with experience in building and maintaining distributed systems.

Requirements

• Experience building solutions that leverage LLMs.
• Experience building software with agentic AI.
• Experience with PostgreSQL and BigQuery.
• Experience with Google Cloud Platform services.
• Familiarity with multi-tenant SaaS architectures.
• Expertise with NGXS or similar state management solutions.
