Senior Product Manager - Data Lakehouse (f/m/d)

Trusted Shops SE (DE) • Berlin, Cologne

Berlin, Cologne

from today / asap

Your duties

Trusted Shops creates digital trust between people, businesses, and AI agents, with one clear goal: becoming the #1 Community of Trust. Every day, we help businesses build trust online and empower consumers to make confident decisions in an increasingly digital world.

As our products, reporting capabilities, and AI-driven use cases continue to grow, the company increasingly needs prepared, standardized data products – the data basis for self-service reporting, APIs (Metrics-as-a-Service), and AI-driven access via MCP or Chat interfaces. You and your team will own the whole journey from raw data to documented, trustworthy data products that people and machines can actually use.

To strengthen our Data Services department, we are looking for a

Senior Product Manager - Data Lakehouse (m/f/d)

(Hybrid in Cologne or remote in Berlin / Full-time / Permanent contract)

Responsibilities
  • You own the product portfolio and roadmap for the domain, driving the shift from reactive requests ("build the metric asked for") to proactive, reusable metric standards.

  • You run data products end-to-end. You know your consumers, treat them as customers, and track whether they actually trust and use what you ship.

  • Together with your team, you define the semantic layer: metric and dimension definitions, metadata, and documentation that make a data product clear to people working in BI tools and reliable for AI agents.

  • You provide metrics-as-a-service. Your team exposes metrics through an API that product engineering teams integrate directly into their own products.

  • You are the point of contact for internal consumers and product teams: you set expectations, explain trade-offs, and say no when needed. You align shared standards and dimensions with the Finance Data Domain team and work with the Data Platform team as your service provider.

Your profile

  • Several years of product management experience, including ownership of data or analytics products such as data products, semantic layers, data platforms, or data-intensive APIs.

  • Strong data-as-a-product mindset with a focus on consumers, quality, governance, semantic consistency, and measurable adoption.

  • Proven ability to define and standardize metrics and data concepts that can be used consistently across teams and use cases.

  • Demonstrated experience leading in complex environments, setting direction under ambiguity, and making autonomous decisions.

  • Strong stakeholder management and communication skills with the ability to align diverse groups without formal authority.

  • Solid understanding of modern data ecosystems and tooling, ideally including lakehouse architectures, dbt, semantic layers, reporting platforms, and AI-enabled data access patterns.

What we offer yo
  • Hybrid work: Flexible remote work combined with time in our Cologne office

  • Workation: Temporarily work from within the EU, Iceland, Liechtenstein, or Norway

  • Permanent contract with Europe’s trusted brand

  • One “Self Education Day” per month

  • 27 vacation days + 3.5 additional days off (Christmas, New Year’s Eve, Carnival)

  • Buddy program & structured onboarding

  • Individual training and development opportunities

Programming Languages
Programming Languages

Java: Java is used by some of our Tech teams and supports us with components that have complex logic, usually in combination with Spring Boot 

TypeScript: We use TypeScript combined with the React framework in the frontend and also on the server side with NodeJS 

Python: We often use Python when processing or transforming data.

Frameworks
Frameworks

React: React is used when the performance of our solutions is important. Our B2C environment, in particular, benefits from React (shop profiles, trust badges, widgets, etc.) 

Spring Boot: When it comes to complex business logic in Java and Kotlin, we use Spring Boot. It is deployed in ECS

NodeJS: Our focus is on serverless, and we often use typescript in the backend. We mostly use NodeJS in combination with AWS Lambda 

Service & Tools
Service & Tools

Circle CI:  CircleCI is our CI/CD tool for automated builds, testing & deployment 

GitHub:  GitHub supports our internal open source policy and enables cross-team cooperation and feedback 

Ansible: We use Ansible to provide our virtual servers in a repeatable and automated way 

Terraform: Our AWS infrastructure is fully managed with Terraform. This allows us to keep a simple history of all changes and minimise the manual effort. 

Databases & Hosting
Databases & Hosting

DynamoDB: DynamoDB is often used to access large amounts of data in real time. We regularly use it with AWS Lambda to provide a scalable solution. 

PostgreSQL/MySQL: If flexibility of data access is paramount, then we also use relational databases 

AWS:  For us, it's "cloud first" so that we are able to scale the infrastructure of our products. Here we rely on services such as AWS Lambda, S3 and DynamoDB

Right now we are working on a new major project for user management and permissions, which is interesting but also complex and has many aspects that will allow it to be integrated into other components. I really like the fact that, as developers within the team, we can decide which technology and programming language we want to use and how we structure the processes. This can sometimes be a challenge, but it helps us gain a lot of new experience. I can work on anything I want to learn about on self-learning days. And of course we have a very friendly and open working atmosphere. Team building events and mob/pair programming sessions also contribute to this.

I am currently working in the Review Insights team. In this product team, we work on frontends that help our customers, i.e. online retailers, to draw valuable information from the collected reviews. I have another colleague in the team from the front-end team with whom I work closely. This starts with the planning and discussion of solutions and ends with the joint revision of the written code. Overall, the working atmosphere at Trusted Shops is very pleasant and relaxed. Thanks to a specially developed platform solution, each product team can build its own micro frontends and is thus independent of the other product teams. This means that you are not restricted in your choice of framework, for example - however, we mainly use the common JavaScript frameworks. Personal development is also encouraged. This year, for example, I was able to take part in a one-week summer school on the topic of deep learning, and we basically have one day a month at our disposal to continue our education as we see fit.

I build features that help our customers collect and use user feedback effectively, working closely with Product and Design from the first idea to golive. I love the mix of technical challenges, ownership, and seeing the real impact of our work. Our team is open, supportive, and collaborative — a place where questions and ideas are always welcome. Trusted Shops truly invests in personal growth and continuous learning. As a woman in tech, I feel empowered and well-supported, especially through initiatives like the Women in Tech Guild, which give us space to connect and shape meaningful change. Diversity isn’t just a buzzword here — it’s part of the culture.

I'm Nata, Product Manager in the Questionnaire Team of the Business Domain. I've been at Trusted Shops since 2025 and I still notice how much I enjoy working here every day. What motivates me every day is our team. We have an atmosphere that doesn't feel like a given. People help each other, communicate openly and transparently, and you can tell that everyone wants to make an impact and build great products. You can feel exactly that beyond your own team as well. Collaborating with colleagues or other teams never feels like an effort, but like working together towards a shared goal. That makes all the difference for me. If you're looking for an environment where you can work with amazing people on meaningful products, I can wholeheartedly recommend Trusted Shops!

I’m Wiktoria, a Software Engineer in the Consumer Membership Team of the Consumer Domain. I started working at Trusted Shops back in 2022. I really appreciate the culture of fostering education at TPS, we get the opportunity to learn new things or get support to do that outside the company as well. I get to talk to people from different departments, which enables me to own my work and gather new experiences. The guilds at Trusted Shops are a great way to give back and help coworkers, like the Women in Tech or Frontend Guild. I recommend Trusted Shops to anyone who doesn’t want to stop growing and wants to meet amazing people!
