We will only consider candidates already based in the Bay Area.\nWho You Are: Zūm is modernizing its iOS experience, and we're looking for a Senior iOS Engineer to help drive that work. Our iOS surface area spans multiple apps - Driver, Parent, Student, School, and Charter - that need to feel like one coherent product, moving thousands of students, vehicles, and school districts through a real-time logistics network.\nYou're a strong individual contributor who wants real influence over technical direction: architecture decisions, modernization strategy, and how the team approaches iOS engineering, while staying hands-on writing production code. This isn't a feature-factory role - you'll be a key voice in setting the technical bar for iOS at Zūm.\nYou'll work closely with our mobile lead, product, design, and engineering leadership on what the platform should look like, then help build the efforts that get us there.\nWhat You'll Do:\nHelp own the architecture and technical roadmap for the iOS platform\nContribute to modernization efforts that move the codebase toward a modern, scalable, shared platform underneath multiple apps\nBalance new feature delivery, legacy maintenance, and platform modernization work as we prepare the app for faster feature delivery\nPartner closely with our mobile lead, product, design, and engineering leadership on technical direction, and collaborate with mobile engineering partners on shared work\nWork across a wide surface area of APIs and services, bringing consumer-app polish to an operationally complex, enterprise-scale problem\nHelp set the technical bar for iOS at Zūm: code quality, architecture patterns, and how the team approaches modernization\nLeverage AI tooling to accelerate development, improve code quality, and speed up modernization work\nModernize legacy features of the app toward current SwiftUI patterns without stalling feature delivery\nContribute to a shared platform layer that multiple Zūm apps (Driver, Parent, Student, School, Charter) can build on top of, instead of duplicating logic across codebases\nRework how the app handles a large and growing surface area of APIs so the codebase stays maintainable as complexity increases\nImprove app performance and memory footprint, and build out telemetry/monitoring so the team can see how the app behaves in production\nHelp identify which parts of the current app are worth keeping versus updating, and execute\nWhat You Bring To Zūm:\n5+ years of professional iOS engineering experience, with real depth\nStrong, current command of Swift and SwiftUI; you're living in modern iOS development\nExperience owning meaningful parts of a consumer-facing app end-to-end, not just a single feature, page, or internal tool\nA product-first orientation: comfortable with infrastructure work, but your track record is primarily product-driven\nExperience working in a complex, consumer-facing app environment (think feature-rich apps with a large user base vs. a narrow enterprise tool or an SDK)\nComfort contributing to architectural decisions and modernization efforts at scale\nExperience modernizing a legacy iOS app while it's still shipping features (preferred)\nBackground at a company with a small-to-mid-sized mobile team, where you had real hands-on ownership (preferred)\nExperience partnering with an engineering leader or mobile lead on setting technical direction (preferred)\nBonus Points:\nDomain experience in logistics, mapping, or fleet-style products\nExperience working across multiple related apps sharing common infrastructure or design systems\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: $200,000 - $240,000 plus stock options.","description_format":"text","description_chars":4277,"description_truncated":false,"requirements":{"experience_years_min":5,"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":34,"band":"fade","label":"Fading","p_open":1,"p_active":0.764,"p_room":0.44,"age_days":61,"expected_fill_days":51,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-11-02T06:13:15Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":true},"html_url":"https://alion.io/job/ridezum-senior-ios-engineer","json_url":"https://alion.io/job/ridezum-senior-ios-engineer.json","meta":{"generated_at":"2026-11-02T17:19:27Z","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":24081,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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-senior-ios-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-senior-ios-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-senior-ios-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-senior-ios-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fridezum-senior-ios-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":703410}},{"tool":"search_jobs","arguments":{"company":"ridezum.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":703410},"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.
