BarcelonaEngineering
- Engineering /Full-time /HybridWho we are: Headquartered in Seattle and Barcelona, we’re a values driven, fast-growing tech company focused on building safe and personalized experiences tailored to the needs of each unique pet. We’re investing in AI as a business accelerator and provide every team member access to AI tools in service of creating better experiences for our community.
We are proud to be recognized as a great place to work, having been named among the 100 Best Companies to Work For in Seattle Business Magazine and Washington’s Best Workplaces in the Puget Sound Business Journal. We help other developers at Rover build high quality experiences quickly by focusing on underlying tools and frameworks. We 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.
We maintain the shared library of re-usable components that make it easy to build cross-platform apps quickly.
Moving the website to be served from Next.js. Making it easier to build with AI. Moving 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. Managing Rover’s adoption of modern tech
- notably Next.js, React Query, Expo, and others. TechnologiesRover.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. At Rover, we deploy to the web 40-60 times a day,



with a median review -> merge time for PRs of 3 hours. The roleWe 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:Solve complex technical problems at the fundamentals of our web and React Native clients.
Build cross-platform code that works across both web and React to set a technical roadmap and vision for the team. Represent Client Platform in broad forums and collect feedback that helps inform the team’s roadmap and vision. Help mentor and coach more junior engineers.
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.
This 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. 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. It also impacts how we accomplish our work, from reorganizing how we go about our days to restructuring PR descriptions. AI should be used to expand understanding, not substitute for it. “Claude did it” is not an excuse. 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. Your qualificationsWe 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:7+ years as a professional software developerExpertise with Javascript frameworks (especially React) and component-driven design.

Rigor in automated testing, code quality, and engineering standard methodologies.
A focus on observability, a propensity to ship code with effective monitoring and logging.
Intuition for when to call it "good enough", and when to put in the extra time to polish.
