Descrição da oferta de emprego

At A Glance

We’re one of the fastest-growing companies in unattended retail tech - 150+ people, 5 countries, hundreds of customers, and a product that’s redefining how the world shops.

We're looking for a seasoned and thoughtful Senior Python Software Developer who thrives on building reliable, scalable backend systems and takes pride in writing clean, maintainable code. You care deeply about long‑term architecture, performance, and well‑structured APIs that power critical services and integrations. You’re the kind of engineer who enjoys solving complex problems at scale, architecting robust solutions, and mentoring others to do the same. Pragmatic, proactive, and deeply invested in doing things the right way.

What You'll Do

• Practice test‑driven development (TDD)
• Develop and maintain Python applications that run on embedded hardware (e.g., NUCs), designed for reliability in both connected and disconnected environments.
• Handle intermittent connectivity: buffering, retry mechanisms, local caching/syncing with remote APIs. Design and implementation of synchronization strategies between local data and cloud systems (eventual consistency, conflict resolution).
• Lead by example through thorough code reviews, championing best practices in clean architecture, modularity, and performance optimization.
• Help onboard new developers, provide thoughtful feedback, and support the growth of team members through collaboration and technical guidance.
• Maintain clear, comprehensive technical documentation for APIs, services, and architectural decisions.

What You'll Bring

• Experience: 8+ years of experience, with a strong track record of building and scaling Django based applications. Familiarity with running Python services on constrained environments (e.g., x86 NUCs, Raspberry Pi, etc.).
• Python & Django: Deep expertise in modern Django architecture and Python development. Comfortable with asynchronous tasks, REST APIs, and integrations.
• Databases: Proficient in PostgreSQL and SQLite, with a strong understanding of efficient ORM usage and performance‑aware query design.
• Testing & Quality: Experienced in test‑driven development (TDD)
• Soft Skills: Good communication and collaboration skills, with the ability to clearly explain complex technical concepts with team members.

Why Join Us

• A role that matters - brand is core to our growth, not a side gig
• A no‑BS, international team that cares deeply and moves fast
• A clear path to grow, own, and shape your area
• Offices in Zurich, London, and 4 other countries - but no office politics
• The usual: budget for personal development, benefits for your well‑being, and some decent swag
