We help other developers at Rover build high quality experiences quickly by focusing on underlying tools and frameworks.\nWe manage and build out core tooling and platforms for frontend development across the web and mobile apps at Rover. We on rare occasion will work in our Django backend, but it’s not a focus for our team. We are looking for this role to be primarily focused on web and React Native frontend.\nSome of our key investments :\nContinuing to expand our cross-platform Design System. We maintain the shared library of re-usable components that make it easy to build cross-platform apps quickly.\n\nMoving the website to be served from Next.js. We are migrating the fundamental tech used to serve Rover.com to a community supported SSR platform.\n\nMaking it easier to build with AI. Building workflows, skills, techniques, and approaches for AI-based development and migrations across all teams.\n\nMoving Rover to a React Native-first app + development cycle. We are completing our React Native migration (now serving 90+% mobile views) and fully migrating to a React Native development cycle.\n\nManaging Rover’s adoption of modern tech - notably Next.js, React Query, Expo, and others.\n\nAs a Platform team, we build out the fundamental tech that powers the internals of Rover.com and the mobile apps. We empower developers to be able to focus more on building great experiences than fighting their tech.\nTechnologies\nRover.com is primarily built in React, served either from a SSR or Django backend, and compiled with Webpack. Our client API is written in Python in Django, which serves over 2 billion requests a month. Our mobile apps are a majority React Native.\nOur development environment centers around ready-to-use Codespaces. At Rover, we deploy to the web 40-60 times a day, with a median review -> merge time for PRs of 3 hours. So all that to say - we prioritize shipping small, incremental work often and quickly!\nThe role\nWe are looking for someone with a primarily web development background who is excited to work both on Web React and React Native. As a senior engineer on our team, you will:\nSolve complex technical problems at the fundamentals of our web and React Native clients.\n\nWork to set technical standards across Rover; then evangelize and educate on those standards.\n\nBuild cross-platform code that works across both web and React Native.\n\nHelp to set a technical roadmap and vision for the team. We don’t have a partner Product Manager, and so “set our own destiny” in a sense.\n\nWork with other engineers in Barcelona to help mentor them and answer questions on Client Platform topics.\n\nRepresent Client Platform in broad forums and collect feedback that helps inform the team’s roadmap and vision.\n\nHelp mentor and coach more junior engineers.\n\nWe are expanding our team’s presence in Barcelona. We are looking for this role to be a mix of contributing and driving the frontend platform while also supporting and upleveling other Barcelona teams.\nThis is a hybrid position that has the minimum expectation to work out of our Barcelona Office in the Poblenou neighborhood two days per week on Mondays and Thursdays. For this reason, candidates must be based in Barcelona or willing to relocate.\nAI/LLM based development\nRover engineers, including this team, are heavy users of Claude for daily engineering practices. We have seen the benefits over the last year, and are convinced that we can build software that is better, more ambitious, and more quickly by smartly using these tools. It is an expectation that you adopt those practices in role, and ideally bring experience and perspectives of your own.\nAI Native\nClient Platform aims to generally be “AI Native” with work. We are reworking our workflows to adopt AI practices to be central. This means things such as: using workflows to handle large migrations, iterating on Claude skills, developing codebase context. It also impacts how we accomplish our work, from reorganizing how we go about our days to restructuring PR descriptions.\nPrinciples\nAlongside our move to AI Native workflows, we recognize that LLMs can’t do everything. These are actively being developed, but a few principles / working agreements on our team around AI use are:\nYou are still responsible for your code. AI should be used to expand understanding, not substitute for it. “Claude did it” is not an excuse.\n\nText intended for humans should be written by humans. Slack messages, PR descriptions, design docs, etc should all still be written by you. We don’t want to read your undigested Claude output - copy-pasting AI output is just shifting the burden of comprehension to another.\n\nPR authors are responsible for making their PRs easily reviewable. The more complex/large a PR, the more the author needs to do for others.\n\nYour qualifications\nWe are looking for a senior level engineer, with a rich background of solving complex web and react native issues. You may not have all of these, but some of the things you will bring are:\n7+ years as a professional software developer\n\nExpertise with Javascript frameworks (especially React) and component-driven design.\n\nExperience in React Native development.\n\nExpertise in multiple parts of our tech stack (see above).\n\nExperience building re-usable frontend libraries.\n\nExperience handling large-scale technology upgrades across a broad range of a codebase.\n\nAn excitement for defining technical standards that make sense for the organization.\n\nExperience coaching more junior developers.\n\nRigor in automated testing, code quality, and engineering standard methodologies.\n\nA focus on observability, a propensity to ship code with effective monitoring and logging.\n\nIntuition for when to call it \"good enough\", and when to put in the extra time to polish.\n\nYou’re aligned with Rover Core Values.\n\nBenefits of working at Rover\nLong-term incentive plan with a company performance-based cash payout\nPension plan\nPrivate medical insurance\n25 days PTO\nMeal allowance and flexible compensation plan (transport and nursery)\nGym membership\n€450 to cover the costs associated with the adoption of a pet\nAnnual €150 wellness reimbursement\nFlexible work hours, sometimes you'll need to be in at certain times, but on the whole, we're pretty flexible when it comes to managing workload and time\nGrab snacks, fresh fruit, in our kitchen to keep yourself going \nRegular team activities, events, game nights, and more\nDog-friendly office\nCompensation\nIn the greater Barcelona area the first-year salary range is €62,722 - €76,027. Additionally, Rover offers a long-term incentive plan with a company performance-based cash payout and benefits to full-time employees.\nThe cash compensation offered for this role will be dependent on the candidate's experience, qualifications, skills, and abilities as demonstrated in the interview and hiring process.","description_format":"text","description_chars":6886,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Flexible schedule","Gym membership","Health insurance"],"hiring_locations":[{"name":"Spain","iso":"ES","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Pet Food, Supplies & Care","Local Services Marketplaces"],"lifecycle":[{"event":"open","at":"2026-10-15T09:07:33Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":69,"reasons":["conf:3","win:early"],"computed_at":"2026-10-15T16:02:24Z"},"pay":{"stated_usd_annual":84551,"is_top_pay":false},"html_url":"https://alion.io/job/rover-senior-frontend-platform-engineer","json_url":"https://alion.io/job/rover-senior-frontend-platform-engineer.json","meta":{"generated_at":"2026-10-15T16:02:24Z","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":24444,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":685870},"rest":"https://alion.io/mcp/rest/get_company?id=685870"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frover-senior-frontend-platform-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%2Frover-senior-frontend-platform-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%2Frover-senior-frontend-platform-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/rover-senior-frontend-platform-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frover-senior-frontend-platform-engineer"}]}
