Your qualifications
- 7+ years of experience as a professional software engineer, with a strong track record of delivering backend systems.
- Technical leadership: you've mentored engineers, driven architectural decisions, led technical design reviews, or shaped team engineering practices, formally or informally.
- 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)
- Observability mindset: experience instrumenting services with structured logging, metrics, tracing, and alerting. You care about understanding system behavior in production, not just at deploy time.
- 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. You understand how to write effective prompts, validate AI output critically, and integrate these tools into a professional workflow.
- 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.
A note on qualifications: we know great candidates don’t always match every requirement. If you’re excited about the role but don’t meet all the listed qualifications, we still encourage you to apply. You might bring strengths or perspectives we haven’t considered—and we’d love to learn more.
Nice to have
- 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.
- Experience pushing the boundaries of AI-assisted development, building custom workflows, automating repetitive tasks, or using AI tools beyond basic code completion.
General skills
- You are a collaborative team player who lifts others through constructive feedback, knowledge sharing, and pairing.
- You bring analytical thinking to new problems and are energized by ambiguity.
- 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).
- You love pets! :)
Our style
