Hybrid Remote/ Redwood City, CA Hybrid Full-time USD 210,000 – 240,000 / year

Zūm is hiring a Senior iOS Engineer

Responsibilities

  • Own front end technical decisions and architecture across our Angular codebase, including patterns for state management and reactive UI (RxJS)
  • Lead the Ukraine-based front end team technically: set direction, unblock hard problems, and raise the bar on craft, while still writing production code
  • Work within an existing structure where PMs and backend teams drive most product and design direction, and Front End owns execution and technical quality
  • Partner closely with PMs (who work in Figma with design) and backend engineering to turn direction into shipped, reliable front end systems
  • Push the team's use of AI tooling forward, spotting where we're moving too slowly and driving the automation that changes that
  • Bring technical leadership to infrastructure-level front end work, not only user-facing feature delivery
  • Absorb the tech lead function currently split across two people and consolidate front end technical decision-making under one clear owner
  • Set architectural standards for how our Angular apps handle state, data density, and reactive patterns across dispatch, school, vendor, and maps portals
  • Identify where AI tooling could meaningfully speed up front end development and build the case (and the tooling) to get there
  • Mentor and technically lead engineers on the Ukraine-based team, working within overlapping HQ hours rather than offshore shifts
  • Build trust with PMs and backend leads so that front end execution stays fast and clean even as product direction comes from elsewhere

Requirements

  • Senior+ or Staff-level front end engineering experience, with a track record of technical leadership, not just individual contribution
  • Strong, hands-on experience with Angular; you should be able to step into our stack and start contributing quickly
  • Experience with reactive UI patterns and RxJS or equivalent observables-based architecture
  • Comfort building and owning enterprise, data-dense web applications, not consumer products or analytics dashboards
  • Experience technically leading or mentoring other engineers, ideally across a distributed team
  • Genuine interest in AI-driven automation, with real opinions on where a team could move faster

Nice to Have

  • Experience stepping into or consolidating a tech lead function previously shared across multiple people (preferred)
  • Startup background (preferred; a plus, though not a strict requirement)
  • Experience with mobile web, not native mobile, not React Native (preferred)
  • Domain experience in mobility, logistics, fleet, or other operationally complex enterprise software
  • Experience with mapping or GPS-adjacent UI, relevant to our maps portal surface
  • Experience collaborating closely with design in Figma-based workflows
