Arbeitsbeschreibung - Senior Backend Developer (Python / Django)

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 Engineer who thrives on building reliable, scalable backend systems and takes pride in writing clean, maintainable code. You’ll be joining our cloud team working on our VendLive platform - managing our unattended retail devices across the globe.

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. You’re pragmatic, proactive, and deeply invested in doing things the right way.

What You'll Do

Design and maintain the cloud-side ingestion engines that process telemetry and transactional data from tens of thousands of concurrent connections.
Develop integrations into 3rd party systems ensuring adequate abstraction layers are designed to simplify the data flow between systems.
Work closely with other teams to support them in building our end-to-end unattended retail technology, including contributing to our resilient connectivity/messaging layer, our device-side SDKs, and our front-facing point of sale applications.
Practice test-driven development (TDD) and build code you can trust to work today, tomorrow, and beyond.
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 (swagger, sphynx), 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.
Advanced Python 3.12+, Django, and Django REST Framework experience. Deep expertise in modern Django architecture and Python development. Comfortable with asynchronous tasks, REST APIs, and integrations.
API Resilience: Proven experience building robust, idempotent cloud services that handle retries, failures, and network issues gracefully without causing duplicate operations or data corruption.
Databases: Proficient in PostgreSQL, with a strong understanding of efficient ORM usage and performance-aware query design (query optimization, indexing strategies). Experience with Redis for caching and session management.
Cloud / Infrastructure: Ideally (though not essential) you will have experience building and scaling cloud applications, with knowledge of AWS infrastructure, such as deploying container services, using terraform, and load management for high-availability systems.
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
An 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
The usual: budget for personal development, benefits for your well-being, and some decent swag
