Role
Who you are
- Strong communication and stakeholder management in both English and German (written + spoken)
- Production-level experience in Python for data and AI engineering (pipelines, APIs, orchestration)
- Solid SQL and data modeling expertise (including incremental strategies)
- Hands-on experience with a major cloud provider (AWS, GCP, or Azure)
- Terraform/IaC experience for provisioning cloud infrastructure
- Experience using at least one modern BI tool (e.g., Metabase, Power BI, Looker)
Desirable
- Deep AWS experience (S3, Lambda, Glue, Redshift, OpenSearch)
- Hands-on experience deploying AI/LLM-based systems into production
- Experience using dbt Cloud for transformation pipelines
- Familiarity with tracing and observability (e.g., Langfuse, OpenTelemetry)
- Experience preparing datasets and running supervised fine-tuning (SFT) of LLMs
- Exposure to reverse ETL tools (e.g., Census, Hightouch) or building custom syncs to HubSpot, Slack, APIs
What the job involves
- We’re looking for a senior-level engineer to take full ownership of our data and AI systems, from ingestion and modeling to embedding pipelines and LLM-based applications
- You’ll operate across domains (data infrastructure, BI, and AI), working closely with stakeholders in product, operations, and engineering
- This is a full-stack data role with a dual mandate:
- Build and scale our AI-native data platform
- Help shape and lead a growing Data & AI team as we scale
- We’re early-stage, so you’ll move between strategy and code, long-term design and fast iteration. You’ll lay the groundwork not just for the system, but for the team that will own it
- Architect and deploy AI-powered systems into production (e.g., FastAPI apps with RAG architecture using OpenSearch and Langfuse)
- Optimize agentic workflows, prompt & embedding pipelines, and retrieval quality through experimentation and tracing
- Extend LLM capabilities with supervised fine-tuning (SFT) for in-domain data distributions where RAG alone underperforms
- Build scalable ingestion and transformation pipelines for both proprietary and external data (using Lambda, Glue, Terraform)
- Own embedding pipelines for retrieval-augmented generation systems
- Manage infrastructure-as-code for all core components (Redshift, S3, VPC, IAM, OpenSearch)
- Maintain and evolve a clean, documented data model (dbt Cloud ⇒ leverage Fusion)
- Develop and maintain BI dashboards in QuickSight and/or Metabase
- Provide ad-hoc analytical support for product, sales, and ops teams
- Build event-driven automation and reverse ETL pipelines to serve data or AI outputs back into operational systems (e.g., HubSpot)
- Work closely with stakeholders across engineering, product, and operations to define the right data products and abstractions
- Lay the foundation for a high-performing Data & AI team. Help hire, mentor, and establish best practices as we grow
Our take
Research by the European Commission suggests that real estate is responsible for 35% of emissions and 40% of energy consumption, a figure only set to grow as countries scale their building projects in line with population increases. These figures mean that to achieve carbon neutrality goals, a rapidly growing number of buildings must be renovated over the next few decades.
Founded by members of the APX accelerator by Axel Springer and Porsche, Purpose Green utilises its founders' rich knowledge about the real estate market to decarbonise the real estate sector. Purpose Green compiles data overviews concerning a building’s energy-related construction and renovation requirements through 3D digital twins of properties. These provide a 360-degree overview of a property's energy status and the work needed to elevate its sustainability.
Working with both real estate portfolios and individual property owners, Purpose Green is currently focused on the German market, its 2024 seed funding allowing it to expand its presence there. Time will tell if the company can expand across the continent, but its steady growth and high-demand market mean it has made a promising start.
