• Startup background (preferred).
• Experience with mobile web, not native mobile or React Native (preferred).
• Domain experience in mobility, logistics, fleet, or other operationally complex enterprise software (bonus).
• Experience with mapping or GPS-adjacent UI (bonus).
• Experience collaborating closely with design in Figma-based workflows (bonus).

Responsibilities

• Own front end technical decisions and architecture across the Angular codebase, including state management and reactive UI patterns with RxJS.
• Technically lead the Ukraine-based front end team, set direction, unblock complex problems, raise engineering standards, and write production code.
• Work within an existing structure where PMs and backend teams drive most product and design direction while Front End owns execution and technical quality.
• Partner with PMs and backend engineering to turn direction into reliable shipped front end systems.
• Advance the team's use of AI tooling and drive meaningful development automation.
• Provide technical leadership for infrastructure-level front end work.
• Consolidate front end technical decision-making under one clear owner.
• Set architectural standards for Angular applications across dispatch, school, vendor, and maps portals.
• Mentor and technically lead distributed engineers during overlapping HQ hours.
• Collaborate with PMs and backend leads to maintain fast, clean front end execution.
