Data Engineer - Battery Intelligence

We are looking to for an experienced Data Engineer to join us on our mission to contribute to a greener future. You will be a part of our Battery Intelligence Team at our HQ's in Stockholm.

Within Northvolt, our batteries and factories are producing large amounts of streaming data which then gets captured in our cloud platform, processed, organized, and made ready for analysis. Working within the Battery Intelligence Team, we will together understand, monitor and predict battery health & life across the fleet of connected batteries and develop state-of-the art machine learning solutions. We use technology and data with the goal to build the smartest and greenest battery.

About the job

We are searching for someone passionate about designing and building cloud data platforms for both streaming and batch data ingested from our customers' connected battery systems. You will build systems that handle that data and prepare it for our advanced analytics and machine-learning use cases. You have experience with data at scale and are comfortable developing systems given varying requirements in data volume, variety, velocity and volume. We are looking for a curious life-long learner who takes ownership and is eager to collaborate to build better products. In this role, you will be a vital member of the Battery Intelligence team.

Key responsibilities include

- Design, maintain and monitor cloud architectures comprised of databases, data lakes, orchestrators as well as streaming and batch ingestion systems
- Build and optimize data pipelines for processing large-scale raw data streams from our connected batteries as well as for preparing data sets for advanced analytics and battery intelligence use cases, while ensuring data quality
- Define, build and maintain data models & schemas and make data and analytics results accessible to technical and non-technical stakeholders

Preferred Experience

- Languages: SQL, Python (Go is a plus)
- Data serialization, transfer protocols and file formats
- Very good understanding of SQL, cloud data warehouses (one of Redshift/Snowflake/Firebolt/Databricks) and database technologies in general
- Design and implementation of software in distributed data systems (streaming, delivery semantics, idempotence, partitioning, consistency concerns)
- Data orchestration, pipelining, monitoring, alerting (e.g. Airflow/Luigi, dbt)
- Data modeling (e.g. (de)normalization for OLTP/OLAP), preferably time series data modelling
- Linux/*NIX environments and version control
- Cloud (AWS/GCP/Azure): Data storage, processing, and compute technologies, IaC

Not Required (but bonus points)

- [Bonus] Container orchestration (eg Kubernetes) and/or serverless infrastructure
- [Bonus] Real-time time-series data within (Industrial) IoT applications
- [Bonus] Manufacture industry and/or Li-ion technology experience
- [Bonus] Engineering foundation understanding (electro/mechanical/chemical/physical), preferably within the energy domain
-
[Bonus] Web services to expose data to consumers

-
[Bonus] Python: Data analysis and visualization (jupyter, pandas, matplotlib/seaborn/bokeh/plotly etc.)


Skills

- Excellent English written and oral communication skills
- Independent, organized and entrepreneurial
- Passionate team collaborator that can thrive in a diverse international environment (100+ nationalities and counting)
- Qualities that we value are flexibility, sense of quality, friendliness, motivation to take on new challenges, grit and a sense of humor


Northvolt makes green batteries for a blue planet. Affordable cells and high-quality battery systems. All manufactured with a record-low carbon footprint. Purposely built to provide Europe with the opportunity to switch to renewable energy – efficiently and entirely.

To accomplish this, we do things differently. We design, manufacture, and recycle everything under one roof. We even build our own factories. All this is incredibly challenging and requires us to think in unconventional ways. We’re constantly experimenting, learning and adapting to make batteries so great – they will one day make oil history.

Northvolt is growing fast. We’re staffing our international office in Stockholm, our R&D facility, Northvolt Labs, in Västerås, as well as our Gdansk facility for production of battery systems. We're also hiring for our gigafactory Northvolt Ett in Skellefteå, Sweden. We want to work with smart individuals from all disciplines. Strong individuals that truly want to make a positive impact on the future. Those of us already on board share a passion for our mission. We’re prepared to work hard in pursuit of excellence. We enjoy the ride and our main drive is to make a difference for real. As a team, we’re dedicated to thinking new, working hard and having fun.
