Has empathy for users and enjoys building customer-facing products that improve people's and pets' lives.

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.

Brings their own unique background to the team, adding fresh ideas and perspectives.

Cares deeply about code quality, maintainability, and engineering craftsmanship; writing code that is clear, well-tested, and built to last.

Is equally eager to share their knowledge and help foster a culture of learning through mentoring, code reviews, and technical leadership.

Your qualifications7+ 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
