Senior Full Stack Engineer (f/m/d)

We are looking for a Senior Full Stack Engineer (Senior Product Engineer) to own the technical direction and delivery of solutions in one of our teams. You aren’t just here to write code - you are a partner in the product journey, helping us shape architecture, refine the work breakdown, and advocate for performance and security at every step.

This is a full-time, hybrid position based in Vienna. We value in-person collaboration, so regular office presence is a priority (3 times a week).

Some of the things you’ll do:

In the first month:

• Get to know your product development team and get familiar with our products, technologies, systems & architecture, processes and practices.
• Absorb our engineering culture, start coding and ramp-up quickly within the Adverity universe.

In the first 6 months:

• Support your product development team with deep code reviews, guiding them towards better system quality and engineering practices.
• Participate in shaping new features by getting your hands dirty in PoCs, breaking down technical scopes, and commence working on team deliveries.

Beyond the first 6 months:

• At this point, you know theAdverity platform very well, both product and tech.
• Participate in strategic cross-product engineering initiatives and help product development teams towards pragmatic technical decisions based on limited context, striving to constantly improve maintainability and reliability.
• You increase your impact beyond your product development team to the whole engineering team & beyond.

We’re excited if you have:

• Product-driven mindset: a strong focus on understanding users and solving real problems with intuitive, user-friendly tools.
• Daily use of AI tools (e.g. coding copilots, LLM-based design assistants, automation agents) and the ability to integrate AI reasoning and automation into workflows across coding, documentation, testing, and deployment.
• Fluency in Python and (preferably) the Django framework, with experience managing large-scale production systems and building REST APIs.
• Strong communication and collaboration skills: you’re proactive, listen carefully, and collaborate closely with product, design, engineering, and other stakeholders.
• A passion for learning, experimenting, and turning new AI tools into practical, repeatable workflows - always keeping user value at the core.

Nice to have:

• During your career you successfully mentored and coached engineers.
• Experience with data products and its challenges.
• Skill in demonstrating AI-driven productivity to peers and driving adoption within technical teams.

Why you’ll love it here:

• Flexible working hours and home-office

• Regular team events
• Modern and stylish offices
