You’ll join one of our product teams, taking end-to-end ownership of features from database schema to UI component. We know full-stack means different things to different people. You might be deeply experienced in Java/Kotlin and Spring Boot, with growing frontend skills and a genuine desire to own the UI. Or you might be a seasoned Angular developer who’s built real backend services and wants to go deeper. Either profile works — what matters is that you want to work across the stack and take pride in delivering complete, high-quality features. We’re also leaning heavily into AI-accelerated development. We see AI as a force multiplier for engineering velocity, and we’re actively investing in tools, workflows, and practices that let our engineers ship faster and tackle more ambitious problems. We want people who are genuinely excited about using AI to accelerate their work, not just curious about it, but already experimenting with it and eager to push the boundaries of what’s possible.

Partner with designers and product managers to translate requirements into complete, working solutions. - Innovate & Improve – Tackle complex technical problems that span the full stack, propose innovative solutions and continuously improve our development practices, tooling, and user experience. - AI-Accelerated Development – 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. What We Need: - Full-Stack Mindset – A genuine desire to work across the entire stack, not just tolerance for it. You take pride in delivering complete features and are eager to deepen your skills on both sides. - Strong Foundation in One, Proficiency in the Other – Deep expertise in either Java/Kotlin and Spring Boot or Angular and TypeScript, with demonstrated hands-on experience in the other. You bring senior-level strength to your primary domain and solid working ability across the stack. - Technical Excellence – 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. - Problem-Solving Skills – Demonstrated ability to analyze and solve complex technical problems that span multiple layers of the system, with a keen eye for identifying potential issues and implementing effective solutions. - Quality Focus – Strong commitment to code quality, testing practices, and software development best practices across the stack. Experience writing well-tested, maintainable code. - Technical Communication – Ability to clearly communicate technical concepts and decisions, participate effectively in code reviews, mentor other engineers, and contribute to a positive team culture. - System Understanding – Ability to understand system architecture and how frontend and backend components interact, with experience in building and maintaining distributed systems.
