We will only consider candidates already based in the Bay Area.\nWho You Are: We're hiring our first HQ-based 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.\nYou'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.\nYou'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.\nWhat You'll Do:\nOwn front end technical decisions and architecture across our Angular codebase, including patterns for state management and reactive UI (RxJS)\nLead the Ukraine-based front end team technically: set direction, unblock hard problems, and raise the bar on craft, while still writing production code\nWork within an existing structure where PMs and backend teams drive most product and design direction, and Front End owns execution and technical quality\nPartner closely with PMs (who work in Figma with design) and backend engineering to turn direction into shipped, reliable front end systems\nPush the team's use of AI tooling forward, spotting where we're moving too slowly and driving the automation that changes that\nBring technical leadership to infrastructure-level front end work, not only user-facing feature delivery\nAbsorb the tech lead function currently split across two people and consolidate front end technical decision-making under one clear owner\nSet architectural standards for how our Angular apps handle state, data density, and reactive patterns across dispatch, school, vendor, and maps portals\nIdentify where AI tooling could meaningfully speed up front end development and build the case (and the tooling) to get there\nMentor and technically lead engineers on the Ukraine-based team, working within overlapping HQ hours rather than offshore shifts\nBuild trust with PMs and backend leads so that front end execution stays fast and clean even as product direction comes from elsewhere\nWhat You Bring To Zūm:\nSenior+ or Staff-level front end engineering experience, with a track record of technical leadership, not just individual contribution\nStrong, hands-on experience with Angular; you should be able to step into our stack and start contributing quickly\nExperience with reactive UI patterns and RxJS or equivalent observables-based architecture\nComfort building and owning enterprise, data-dense web applications, not consumer products or analytics dashboards\nExperience technically leading or mentoring other engineers, ideally across a distributed team\nGenuine interest in AI-driven automation, with real opinions on where a team could move faster\nExperience stepping into or consolidating a tech lead function previously shared across multiple people (preferred)\nStartup background (preferred; a plus, though not a strict requirement)\nExperience with mobile web, not native mobile, not React Native (preferred)\nBonus Points:\nDomain experience in mobility, logistics, fleet, or other operationally complex enterprise software\nExperience with mapping or GPS-adjacent UI, relevant to our maps portal surface\nExperience collaborating closely with design in Figma-based workflows\nThe targeted base salary range for this role is listed in the compensation section below. Actual salary may be above or below this range based on factors such as location, skills, and relevant experience. In addition, this position may include additional compensation in the form of equity or commissions. If you are a full-time salaried or hourly worker, we offer the following benefits: Medical, Dental, Vision, 401(k), Holidays, Wellness, Vacation, and more. The targeted pay range for this role in CA, USA is: $240,000 - $280,000 plus stock options.","description_format":"text","description_chars":4284,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Stock options"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Public Transport"],"lifecycle":[{"event":"open","at":"2026-09-11T03:26:29Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.458,"p_room":0.28,"age_days":274,"expected_fill_days":56,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-29T05:49:05Z"},"pay":{"stated_usd_annual":280000,"is_top_pay":true},"html_url":"https://alion.io/job/ridezum-staff-front-end-engineer","json_url":"https://alion.io/job/ridezum-staff-front-end-engineer.json","meta":{"generated_at":"2026-10-29T17:20:52Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":25945,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":685702},"rest":"https://alion.io/mcp/rest/get_company?id=685702"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fridezum-staff-front-end-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fridezum-staff-front-end-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fridezum-staff-front-end-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/ridezum-staff-front-end-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fridezum-staff-front-end-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":703428}},{"tool":"search_jobs","arguments":{"company":"ridezum.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":703428},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
