About the role

At Immowelt, part of the Aviv Group, you’ll work on one of Europe’s leading real estate platforms, serving over 50 million monthly users across both B2C and B2B journeys.

Our mission at Aviv is to unlock everyone’s perfect place, and at Immowelt, technology is central to delivering that at scale. This role offers the opportunity to lead a team in a product-driven, international environment, shaping architecture, engineering culture, and delivery practices while solving complex challenges in data, performance, and distributed systems.

We’re looking for a hands-on Engineering Manager / Lead Engineer with a strong technical foundation and leadership mindset to guide a cross-functional team. You’ll own team performance, predictable delivery, and engineering quality, while still contributing to architecture and code where it matters most.

You’ll report to the Engineering Director and work closely with Product, Design, and Analytics to drive meaningful business impact.

In this role, you will:

Team Leadership & People Development

• Hire, mentor, and develop engineers through continuous feedback and performance conversations
• Foster a culture of ownership, collaboration, and engineering excellence
• Ensure accountability for outcomes, quality, and predictable delivery

Delivery & Execution

• Own end-to-end delivery, including planning, prioritisation, and dependency management

• Partner with Product to define roadmaps and OKRs
• Communicate progress, trade-offs, and outcomes to stakeholders

Technical Leadership (hands-on ~40%)

• Build scalable, reliable, and maintainable systems following clean architecture principles
• Drive performance optimisation and cost efficiency
• Champion modern development practices, including AI-assisted workflows

The skills you bring:

• 5+ years of software engineering experience
• 2+ years of people management experience with ownership of team outcomes
• Proven track record of delivering high-quality software in a predictable way
• Strong experience in system design and distributed architectures
• Ability to balance process and pragmatism — improving quality without adding unnecessary complexity
• Experience with modern cloud environments (AWS or similar), CI/CD, and containerisation
• Familiarity with observability and operational excellence practices
• Strong communication and stakeholder management skills (English required; German is a plus)
• Curiosity and adaptability to quickly learn new technologies and domains
