Pregnancy, childbirth, and early parenthood bring about a lot of changes. And with each phase, new questions arise: small ones, big ones, practical ones, emotional ones. Glimmer helps to see more clearly what's happening right now, what's important, and what's right.
We combine in-depth expert knowledge, a digital midwife consultation service, and practical tips in one app. This way, customers will find reliable answers, prenatal and postpartum recovery classes, and support all in one place. Accessible, compassionate, and tailored.
Glimmer is covered by over 80 health insurance providers and supports customers from their child's first heartbeat to their first steps. So they can navigate this journey with greater clarity, confidence, and peace of mind.
Glimmer is a Berlin-based start-up with around 40 employees. As our Senior Data Engineer, you'll be part of the Data & Engineering team and play a key role in building the data foundations that help us turn insight into better care for every family we support.
Tasks
Role Overview:
We're looking for a motivated and highly autonomous Data Engineer to build and own the foundations of our data platform. You'll enjoy this role if you like ownership, can design reliable and scalable data pipelines, and care about giving every team clean, trustworthy data. You'll also be handling sensitive health data, so we need someone who treats privacy and security as core engineering principles.
What Success Looks Like:
Over the last seven years, and through several acquisitions, our data landscape has grown into a patchwork of systems, pipelines and workarounds. Your biggest impact will be replacing that complexity with a single, modern data warehouse and a platform that is simple, well documented and easy to build on.
In practice, success means:
- Within your first 3 months: You've mapped our current data landscape, including legacy systems, inherited sources from acquisitions, pipelines and dependencies, and you've shared a clear target architecture and migration plan that the team supports.
- Within 6 months: The foundations of the new data warehouse are live, the most important data sources are migrated, and the first legacy pipelines and tools have been retired.
- Within 12 months: The new warehouse is our single source of truth. Redundant systems are gone, core metrics are defined consistently across the business, and teams trust the data without double-checking it.
- Throughout: Data is easier to find, understand and use. Onboarding a new source or answering a new question takes days, not weeks, and the platform is documented well enough that it doesn't depend on any one person.
What You'll Do:
- Design, build and maintain scalable ETL/ELT pipelines using SQL, Python and PostgreSQL
- Own and evolve our cloud data infrastructure on AWS (primarily EC2 & RDS), balancing performance, reliability, security and cost.
- Own the end-to-end engineering of our automated insurance invoicing pipeline, so that reimbursement, claim status and financial data flow accurately and reliably into downstream systems
- Build and maintain ingestion pipelines that connect product, web, CRM and advertising platforms (e.g. Amplitude, Meta, Google Ads, HubSpot) into a unified data model
- Develop and maintain integrations with internal and external tools and SaaS products via REST APIs
- Design and implement data models and warehouse schemas that support business reporting, product analytics, experimentation and regulatory requirements
- Put data quality, testing, monitoring and alerting in place so problems are caught before they reach stakeholders
- Orchestrate and automate workflows, and apply software engineering best practices (version control, CI/CD, code review, documentation)
- Make sure data is handled in line with GDPR, health data privacy requirements, and internal policies, including access control, pseudonymisation and retention policies
- Work closely with Marketing, Product and Finance to understand their data needs and deliver datasets that feed tools such as AWS Quicksight
- Share knowledge and coach team members on data concepts, tooling and best practices
Requirements
Your Profile:
- 3+ years' experience in Data Engineering or a closely related role, ideally in a startup or scale-up
- Strong hands-on skills in SQL, Python, PostgreSQL and AWS (EC2/RDS)
- A track record of building and owning data pipelines and warehouse architectures from scratch in fast-moving environments
- Experience with API integrations, workflow automation and version control (GitHub)
- Solid understanding of data modelling, data quality practices and pipeline observability
- Awareness of data privacy and security, ideally with experience handling sensitive or regulated data (GDPR)
- Nice to have: experience with orchestration tools (e.g. Airflow, Dagster), transformation frameworks (e.g. dbt), infrastructure as code, or BI tools like AWS Quicksight
- A high degree of autonomy, curiosity and ownership
- Fluent in English, German is a plus
