We thrive on innovation, rapid execution, and delivering top-tier products that make a real impact in the transit industry.\nAbout the team\nThe AI Platform team sits at the center of Spare’s product. We own the shared services every Spare product depends on, along with Nutshell, Spare’s design system. The systems we support serve millions of AI voice calls every year and help tens of thousands of people get where they need to go.\nThe user interfaces we build are used heavily by transit agencies around the world: dispatchers watching live vehicles, planners modelling a season of service, schedulers building driver shifts for the month ahead. Dense screens, long shifts, and real consequences when something is hard to use.\nYou’d be joining a cross-functional team of developers, a product manager, and designers, doing customer-facing work with real human impact.\nAbout the role\nThe way software gets built is changing. Developers at Spare aren’t waiting on someone else’s spec. They’re talking to customers, making design decisions, and owning problems from discovery through a shipped solution. AI has dramatically expanded what a single developer can deliver, and this team leans into that.\nAs a Senior Frontend Developer, you’d turn the Design team’s direction into the product people actually use. You’d own the technical calls that keep our interfaces accessible, fast, and organised in the code, so other developers and our AI workflows can build on them with the right guardrails.\nThe other development teams are your customers too. You’ll clean up the interfaces we already have, lay the UI foundations for emerging products, and take people with you as they build on top.\nHybrid. Downtown Vancouver, three days a week (Monday, Wednesday, and Friday).\nWhat you’ll do\nOwn and extend Nutshell: tokens, shared components, and the patterns every other team builds with\n\nRefactor the existing frontend where necessary, creating a highly organised environment and setting the UI foundations for emerging products\n\nShape the system so developers and AI agents produce accessible, consistent UI by default\n\nFill in the gaps that don’t get explicitly designed: empty states, keyboard behaviour, screens under real operational load\n\nEnable the people who build on your work: documentation, feedback, and the occasional workshop to drive adoption\n\nWhat you’ll bring\nA track record of data-dense interfaces. Complex operational UI, not just marketing sites\n\nDeep knowledge of our frameworks. React, TypeScript, modern CSS, and component API design\n\nExperience getting a design system adopted. A component library other developers depend on, and the buy-in to get it used\n\nThe ability to work across the stack. You can carry a feature past the frontend, but the interface stays your specialty\n\nCuriosity about AI-assisted development. You don’t need to be an expert today, but you’re already experimenting and can explain the decisions in the code you ship\n\nClear communication. Comfortable with design and product, and able to write the doc people actually read\n\nA high bar and real ownership. Ambitious standards, proactive communication, and the drive to move without waiting for direction\n\nDepth of experience matters more than a year count. People who thrive here typically have 5+ years.\nNice to have\nExperience in transit, mobility, or logistics\n\nExperience at a high-growth startup at a similar stage\n\nComfort working in design tooling, shoulder to shoulder with designers\n\nExperience coaching other developers without a formal title\n\nDon't meet every single requirement?\nStudies have shown that women and people of colour are less likely to apply to jobs unless they meet every single qualification in the job posting.\nAt Spare, we are committed to creating a diverse and inclusive environment so we strongly encourage you to apply even if you don't believe you meet every single qualification outlined. We also do our best to respond to all applications we receive.\nWhy Join Us?\nWork on challenging technical problems with real-world impact in the transportation industry\n\nA fast-paced, high-impact role in a rapidly growing startup\n\nThe opportunity to take ownership of core systems and drive innovation\n\nA dynamic, collaborative, and supportive team culture\n\nCompetitive salary and equity options\n\nIf you are ready to tackle complex routing and optimization challenges and thrive in a high-performance environment, we'd love to hear from you!","description_format":"text","description_chars":4510,"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"],"hiring_locations":[{"name":"Canada","iso":"CA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Scheduling & Booking Software"],"lifecycle":[{"event":"open","at":"2026-10-02T05:37:34Z"}],"visa":[],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":1,"p_active":0.76,"p_room":0.9,"age_days":12,"expected_fill_days":31,"reasons":["conf:4","velocity","win:mid","comp:attention"],"computed_at":"2026-10-14T06:34:16Z"},"pay":{"stated_usd_annual":145969,"is_top_pay":false},"html_url":"https://alion.io/job/spare-labs-senior-front-end-engineer","json_url":"https://alion.io/job/spare-labs-senior-front-end-engineer.json","meta":{"generated_at":"2026-10-14T19:50:41Z","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":26204,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":179775},"rest":"https://alion.io/mcp/rest/get_company?id=179775"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fspare-labs-senior-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%2Fspare-labs-senior-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%2Fspare-labs-senior-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/spare-labs-senior-front-end-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fspare-labs-senior-front-end-engineer"}]}
