Product Manager API

Why This Role

immowelt is a leading German digital real estate marketplace and part of AVIV Group. Behind every listing sits a flow of real estate data into and out of our marketplace: import infrastructure, classified listing products and data-as-a-service exports. We are modernizing that foundation, including the move from legacy on-premise infrastructure to the cloud, and we need a Product Manager to own it end to end. This is an opportunity to build and transform, whether you are a strong Senior PM or a mid-level PM ready to grow into broader scope.

The Team You'll Join

You’ll join the Listing Management Products team, reporting to the Head of Product at immowelt and working with cross-functional squads across immowelt and AVIV Group. You’ll partner closely with engineering, design, data, operations and commercial teams.

Our next chapter is about platform enablement and cloud migration — and this role will be central to making that happen.

What You’ll Own

• Product strategy and roadmap: Own the vision, mission, roadmap and backlog for Core Classified and Import Products, aligned with immowelt's OKRs and business targets.
• Product discovery: Define the target state, assess current gaps and map the best transformation path, based on market signals, B2B customer needs, operational pain points and technical constraints.
• End-to-end delivery: Turn complex business and technical requirements into clear scope, acceptance criteria and milestones, and manage priorities, dependencies and risks across several workstreams.
• Platform modernization: Lead the migration from legacy on-premise infrastructure to the cloud, with clear migration plans and transparent communication of the impact on other teams.
• Stakeholder alignment: Align stakeholders from engineering to senior leadership on strategy, priorities and progress, and present roadmap updates and outcomes with clear storytelling.
• Data and measurement: Define success KPIs, north-star metrics and instrumentation for every initiative, and use them to track outcomes and drive improvement.

What We’ll Achieve Together

Success in this role means creating measurable improvements, not simply introducing new processes.

We expect you to help us:

• Improve the success rate of listing imports and the quality of the listing data that flows through our platform.
• Increase adoption of our data-as-a-service exports among the customers they are built for.
• Give leadership reliable visibility into core product KPIs and north-star metrics.
• Make it faster and simpler to onboard and update listings.
• Migrate our import and listing workloads from on-premise to the cloud without loss of data quality.

The exact measures will be agreed based on the priorities and baseline when you join.

What You Bring

We care more about what you have built and improved than a particular title or number of years of experience.

You bring:

• Product management experience, or close hands-on collaboration with product managers, in a high-velocity software product environment.
• Experience with platform enablement, API and integration products, partner ecosystems or data services, ideally in transformation projects where infrastructure and business products are modernized together.
• Technical fluency to take part in architecture discussions, API design and build-versus-buy decisions, with a solid grasp of integration patterns, microservices, event-driven systems and cloud concepts.
• Strong analytical skills and comfort with data querying and BI tools to validate hypotheses and monitor product performance.
• Excellent communication in English and German (B2 or above), and the ability to influence stakeholders without direct authority while owning cross-team impact end to end.

Nice to have: experience in B2B SaaS, PropTech, marketplaces or data platform contexts. We ideally prefer candidates based in Nuremberg, Berlin or Hamburg.

How We Work at AVIV

Our Leadership Behaviours describe not only what we expect people to deliver, but how we expect them to deliver it.

For this role, four behaviours will be particularly important:

All Starts With Me. You take end-to-end ownership, including the impact of your delivery on other teams, and drive problems to resolution rather than waiting for someone else to fix them.

Decide Fast. Deliver Hard. You create clarity across several concurrent projects, make decisions with the best information available and remove blockers rather than create them.

Data Leads. Judgment Wins. You define meaningful KPIs and north-star metrics, separate useful signals from vanity metrics and combine data with judg
