About the Role

We're looking for a Senior Software Engineer to join Karla’s engineering team and build end-to-end solutions that power the post-purchase experience for renowned international brands.

As a Senior Software Engineer, you'll take ownership of complete features from conception to production. You'll leverage modern tools and AI-powered workflows to accelerate development while maintaining high-quality standards.

You'll have the autonomy to architect solutions within your domain and ship code with confidence backed by comprehensive testing. We value engineers who can move quickly without sacrificing craftsmanship: those who know when to reach for AI assistance to handle repetitive tasks and when to dive deep into complex problem-solving.

What You'll Do

• Build complete features end-to-end from database to user interface, owning the full technical stack. We use Python FastAPI in the backend, React/Next.js in the frontend, and Kubernetes for the infrastructure.
• Design and implement scalable systems that handle growth and complexity across all layers.
• Ship high-quality code rapidly by leveraging AI tools strategically for scaffolding, testing, and refactoring while maintaining craftsmanship for complex logic.
• Architect robust APIs and services that power seamless user experiences.
• Optimize system performance across the entire stack, from database queries to API response times to UI rendering.
• Collaborate cross-functionally with product and design to deliver cohesive solutions.
• Drive technical decisions within your domain, balancing pragmatism with long-term sustainability.
• Improve developer experience by championing better tooling, automation, and AI-augmented workflows.
