About The Trust & Safety Engineering Team
It's some of the most important work at Rover, our users are pets, and keeping them safe is the whole point.
We're a cross-functional team of full-stack engineers based in our Poblenou, Barcelona office, working closely with product, design, and data science. We care about clean code, thoughtful collaboration, and building systems people can rely on, and we make time to enjoy each other's company too, from team lunches to coffee on the office terrace.
Takes ownership of problems end-to-end: from understanding the business need, to designing the solution, shipping it, and monitoring it in production
Is able to take loose requirements, collaborate with product managers, designers, and data scientists to determine what needs to be done, and drive a project forward
Cares deeply about code quality, maintainability, and engineering craftsmanship; writing code that is clear, well-tested, and built to last
Is excited about using AI tools to accelerate their workflow, improve code quality, and ship faster. You see AI as a core part of modern software engineering, not a novelty
7+ years of experience as a professional software engineer, with a strong track record of delivering backend systems
~ Strong backend engineering experience, ideally in Python and Django. If your background is in another major backend language (Java, Go, C#, Kotlin), that's absolutely welcome, what matters most is engineering depth, and we'll support you in ramping up on our stack
~ Solid knowledge of relational databases (schema design, query optimization, migrations)
~ Strong testing discipline: you champion automated testing (unit, integration, contract) and treat it as a core part of shipping, not an afterthought
~ AI-augmented engineering: you actively use AI coding assistants (Claude Code, Copilot, or similar) in your daily work, for code generation, debugging, refactoring, code review, and exploring unfamiliar codebases. Comfortable working across the stack: while your strength is backend, you can navigate a React/TypeScript frontend to unblock yourself or collaborate effectively with frontend engineers

Experience with React or React Native, enough to contribute to frontend work when the team needs it
Experience with distributed systems patterns: async task queues (Celery, RabbitMQ or similar), caching layers (Memcached, Redis), and event-driven architectures
Familiarity with search infrastructure (Elasticsearch or similar)
Experience with REST API design at scale (Django REST Framework or equivalent)
Exposure to continuous deployment pipelines and infrastructure-as-code practices
General Skills

You are meticulous about system design and user experience because you want to deliver the best service to your customers
You are comfortable working with agile methodologies (Scrum, Kanban, XP)
Good level of written and spoken English (our engineering team is in Barcelona, but we work in English)
We are proud to be professional software developers building high-quality, scalable, and supportable solutions
We embrace progressive engineering practices, including continuous deployment, automated testing, observability-first development, and AI-augmented workflows powered by tools like Claude Code, every engineer on the team uses AI daily to move faster and build better software
We are serious about the quality of our production operations, with thorough system, application, and user interaction monitoring and anomaly detection
We are passionate about data-driven decision-making
Our teams are integrated, with developers, product managers, designers, and data scientists working side-by-side
