Job description

As the top Swiss e-commerce platform, with a crew of over 4’000 across Switzerland, Germany, and Serbia, Galaxus is poised to move into new markets. Our driving force is our determination to keep challenging the status quo. That’s why we’re on the lookout for characters who’re passionate about making genuine improvements. We’ll give you the freedom and trust to make an impact, to grow with us and to be yourself. Act galactic. Be you.

As a Senior Fullstack Engineer on Team Appic, you're the vital link between our native apps and the web frontend and backend. You build the web layer that lets the app talk to it flawlessly, forging a seamless bridge between web and native and you make sure our backend never misses a beat delivering push notifications.

• Hands-on execution is at the core of what you do: designing, building, and shipping code across the full stack, from frontend to backend
• You build and maintain the web-facing interfaces and APIs the mobile apps rely on, and support the integration of the web application into the native apps via WebViews
• The technical reliability of the push-notification module falls under your care, ensuring the backend can deliver all the pushes the apps need
• Coordinating the development of native features for iOS and Android happens in close alignment with the feature teams involved, including clarifying dependencies and interfaces
• Coaching software engineers comes naturally to you, backed by the interpersonal skills to explain complex topics and concepts clearly
• A strong track record as a hands-on software engineer, deeply involved in designing and building complex solutions day to day
• A Bachelor's or Master's degree in Computer Science (ETH/university/university of applied sciences), or equivalent relevant work experience
• Proven experience (5 years+) in classic fullstack web development, both frontend (ideally React/TypeScript) and backend (ideally .NET/C#). Experience with GraphQL, MongoDB, and mobile development (Swift, Kotlin) is a plus
• Ideally, some experience with the end-to-end lifecycle of mobile apps (Android & iOS) or the motivation and initiative to grow into this area
• A willingness to challenge «how things have always been done» and propose more efficient, automated or effective solutions
• Using creativity and initiative to solve problems and achieve goals
• Fluent English (working language); good German is a plus
• Values, not empty words: Cooperative, innovative, piratesque, responsible, ambitious – these five values are what we practice and preach.
• Courageous thinking: We encourage everyone to think on their feet, and love it when they come up with bold or edgy ideas.
• Uncomplicated approach: Simplicity is at our core. We avoid the unnecessary and focus on what really matters – from overcoming challenges to celebrating our shared successes.
• Flexibility and freedom: We offer working-from-home options, up to 8 weeks of workation, and every position is possible with an 80% workload.
• Rapid growth: With us, growth is a continuous journey. We also support you with 2’000 EDU Points per year for your professional development, so there’s no risk of you getting stuck in a rut.
• Modern: With us you can work with the latest technologies every day, see our Tech-Radar.
• More than "just" work: Take part in our various employee events such as Hackathons, hiking, skiing, Böötlen on the Limmat, LAN Parties or Friday Night Drinks and, if you're interested, contribute to our Techblog.
• More benefits: 25 days of holiday, exclusive employee conditions in our online shop, mobile, internet and TV plans at company rates and many other benefits.

Diversity is our culture.

To build the best team, we want to draw from the full spectrum of talent out there. This means people from all walks of life have the same opportunities with us, regardless of their ethnicity, religion, disability status, gender identity, sexual orientation or age. We believe true inclusion means everyone is welcome and each contribution is valuable.
