We will only consider candidates already based in the Bay Area.Who You Are:We're hiring our first HQ-based web development engineer, a Staff Front End Engineer who will lead front end technical direction for Zūm while staying hands-on as an individual contributor. This role operates as a technical lead; you'll set technical direction, make front end architecture decisions, and lead a team of engineers in Ukraine, while still writing code and shipping features yourself.You'll own the front end behind our dispatch, school, vendor, and maps portals — enterprise, data-dense tools that districts, transportation vendors, and internal operations teams rely on to run complex logistics.You'll work from HQ, in close collaboration with our local Product and Engineering teams. The Ukraine Front End team's hours overlap with HQ until roughly 11am PT, so this role doesn't require working offshore hours.We're looking for an engineer who leads through the work itself, not just the title. Someone who can absorb a tech lead role and immediately make the team better, while staying comfortable that product direction, at least for now, comes primarily from our PM and backend teams. This isn't a fit for someone who wants full front end product ownership from day one. It's a fit for someone who finds real satisfaction in technical craft, mentorship, and making a distributed team sharper, and who's excited to bring AI tooling into how we build.What You'll Do: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 codeWork within an existing structure where PMs and backend teams drive most product and design direction, and Front End owns execution and technical qualityPartner closely with PMs (who work in Figma with design) and backend engineering to turn direction into shipped, reliable front end systemsPush the team's use of AI tooling forward, spotting where we're moving too slowly and driving the automation that changes thatBring technical leadership to infrastructure-level front end work, not only user-facing feature deliveryAbsorb the tech lead function currently split across two people and consolidate front end technical decision-making under one clear ownerSet architectural standards for how our Angular apps handle state, data density, and reactive patterns across dispatch, school, vendor, and maps portalsIdentify where AI tooling could meaningfully speed up front end development and build the case (and the tooling) to get thereMentor and technically lead engineers on the Ukraine-based team, working within overlapping HQ hours rather than offshore shiftsBuild trust with PMs and backend leads so that front end execution stays fast and clean even as product direction comes from elsewhereWhat You Bring To Zūm:Senior+ or Staff-level front end engineering experience, with a track record of technical leadership, not just individual contributionStrong, hands-on experience with Angular; you should be able to step into our stack and start contributing quicklyExperience with reactive UI patterns and RxJS or equivalent observables-based architectureComfort building and owning enterprise, data-dense web applications, not consumer products or analytics dashboardsExperience technically leading or mentoring other engineers, ideally across a distributed teamGenuine interest in AI-driven automation, with real opinions on where a team could move fasterExperience 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)Bonus Points:Domain experience in mobility, logistics, fleet, or other operationally complex enterprise softwareExperience with mapping or GPS-adjacent UI, relevant to our maps portal surfaceExperience collaborating closely with design in Figma-based workflowsThe targeted base salary range for this role is listed in the compensation section below.
