Jobbeschreibung

Please note, this position is based in our Swiss HQ in Mendrisio, Switzerland, which is 7km over the border from Italy and easily commutable from Milan, Como, Varese or Lugano. We are also happy to assist with your relocation to this beautiful part of Europe and we have a hybrid remote working policy.

Your Role:

We’re looking for a Backend Engineer to help us take our product to the next level. This position will take end-to-end ownership of product and feature delivery, from system design and backend architecture to integration with our infrastructure, observability of what gets shipped, and the best practices that keep the team moving fast and sustainably. You'll also help shape how we integrate AI into our workflow and products, both as a tool that makes the team more effective, and as a capability we build for our users.

Key Responsibilities:

• Play a key role in QA’s shift to an AI-first ecosystem
• Be able to produce well-structured, maintainable, idiomatic code with good documentation; unit tests for every feature, bug fixing, and code reviews.
• Collaborate on a cross-functional team, including front-end developers, UI/UX designers and product managers, to quickly deliver new features.
• Work closely with the SRE Team to ensure smooth deployments, ensuring that errors are logged with enough info to debug effectively.
• Contribute to the Backend Chapter, participating in technical discussions and cross-team activities

Your Experience:

• Effective use of AI tools in the development workflow (IDE-integrated assistants, chat-based tools) with strong critical thinking: ability to review, challenge, and validate AI-generated code, craft effective prompts, and still reason independently about algorithms, requirements, and trade-offs
• Solid experience in coding with backend programming languages. Experience with Kotlin and/or Python is an advantage
• Solid experience with relational databases and with other types of databases: PostgreSQL and Redis are an advantage
• Advanced knowledge and experience on modern web patterns: RESTful APIs, WebSocket, GraphQL are an advantage
• Experience with distributed version control systems: Git (GitHub and/or Bitbucket)
• Familiarity with cloud-oriented technologies: Docker, AWS or Azure is an advantage
• Familiar with cloud architecture patterns and best practices for designing highly available, scalable, and secure distributed systems; experience with event-driven architectures is an advantage
• Experience with observability and troubleshooting in production: log monitoring, error tracking, and APM
• Security-minded approach to development: secure coding practices and vulnerability remediation as part of the regular workflow
• Good level of English proficiency, both spoken and written
• Ability to work independently and as part of a team, with a sense of urgency and integrity

Nice to Have:

• Passion for or experience in e-learning projects is a strong bonus
• Hands-on experience building AI-powered features (e.g. LLM integrations, RAG, AI-assisted user experiences) is a strong bonus
• Experience running and monitoring AI products in production: evals, output quality tracking, and observability specific to AI/LLM systems is a strong bonus
