Quick Facts

  • Role: Senior Product Engineer (Web/Mobile)

  • Focus: Delivering production software across web and mobile with modern UI frameworks and AI-assisted engineering

Description

We’re looking for a Senior Product Engineer who can turn product goals into high-quality software across web and mobile platforms. You’ll work across a UI stack that may include React, React Native, and Angular (or other modern frameworks such as Flutter and native iOS/Android) while using AI tools to research, prototype, debug, and ship. Strong logical and abstract thinking is essential.

Responsibilities

  • Own problems end-to-end: convert product goals into practical technical solutions

  • Build across the UI stack: use React, React Native, Angular, or other technologies when they fit the problem

  • Use AI as an engineering tool: accelerate research, implementation, debugging, prototyping, testing, and learning

  • Move between technologies: become productive in unfamiliar frameworks, libraries, APIs, or platforms

  • Craft excellent user interfaces: build polished, intuitive, responsive UIs with strong interaction and UX detail

  • Make good architectural decisions: break complex problems into understandable abstractions and choose appropriate trade-offs

  • Ship through the full lifecycle: implementation, testing, deployment, monitoring, and iteration

  • Collaborate across the stack: work with APIs and backend services as needed for complete features

  • Raise the engineering bar: share knowledge and improve development practices

Requirements

  • Strong software engineering fundamentals and experience shipping production applications

  • Excellent logical, analytical, and abstract thinking skills

  • Ability to understand unfamiliar problems, decompose them, and work independently toward a solution

  • Strong experience in at least one modern application development ecosystem (ideally React, React Native, or Angular)

  • Strong understanding of application architecture, state management, APIs, asynchronous systems, and testing

  • Experience creating high-quality user interfaces with attention to usability, visual polish, responsiveness, and interaction design

  • Practical experience using modern AI-assisted development tools as part of your engineering workflow

  • Strong TypeScript, JavaScript, or comparable programming-language fundamentals

  • Ability and willingness to learn new technologies quickly and not be attached to one framework

  • Ability to work independently and take ownership from an ambiguous problem through to a finished result

Benefits

  • Significant ownership and the opportunity to influence how the team builds web and mobile products

  • Chance to influence how AI is used in engineering and how product development is approached as a team

  • Work in an AI-enabled engineering environment where success is about understanding problems, reasoning about solutions, validating results, and delivering working software
