Job Description

Gridmatic is a high-growth startup and a new kind of energy company, delivering affordable, clean power by optimizing renewable energy and grid-scale batteries. With offices in the Bay Area and Houston, we bring together Silicon Valley–style innovation with deep, hands-on expertise in real-world power markets and energy retail.

As solar and wind become the fastest-growing sources of electricity, variability from weather and grid conditions makes energy prices more volatile. Gridmatic tackles this challenge with industry-leading forecasting and optimization—and gives our team the opportunity to work on problems that truly matter. Forecasting and trading energy are the foundation of what we do. We ingest large-scale data—weather, prices, load, and grid conditions—to build probabilistic machine learning forecasts that drive real operational decisions. Our work directly determines when power is bought, stored, or deployed, turning uncertainty into value for customers and the grid.

Our impact is measurable. Gridmatic is the most profitable participant in ERCOT’s wholesale market and operates the top-performing battery asset in CAISO. Profitable without venture capital, we offer a collaborative, low-ego environment where rigorous thinking, autonomy, and continuous learning are core to how we work.

The role
We’re looking to hire our first data engineer at Gridmatic! Looking for a startup-minded engineer who works closely with our ML and optimization teams to ingest and transform the data critical to all the work we do.

We use a lot of interesting, real-world data - large-scale weather forecasts, timeseries data from the grid and energy markets, and telemetry from physical batteries. We’re looking for someone who’d be able to take ownership of this area to make sure the data is ingested and transformed reliably.

What you might work on:

  • Owning the ingestion and transformation of datasets needed for mission-critical operations like machine learning, renewable energy supply, and battery storage.

  • Designing data models and choosing good data persistence strategies around large volumes of energy and weather timeseries data.

  • Creating data products using DBT and dashboards/visualizations to help us make key business decisions.

  • Helping inform our data architecture, and best practices around storing and using data.

What we’re looking for:

  • A strong data engineer who has worked on large-scale production data pipelines, and can take ownership of critical datasets.

  • Has worked with large-scale data, and makes good choices on data storage and schema design (relational databases, data warehouses, object storage, timeseries data).

  • Has worked at a startup or similar environment, and works well with ambiguity and having a lot of scope/responsibility.

  • Has strong software engineering skills. Being able to write easy-to-extend and well-tested code.

  • Has experience with data processing tools like DBT, spark, kafka, flink, beam, dataflow, etc.

Our stack includes: Python, GCP, Kubernetes, Terraform, Flyte, Temporal, React/NextJS, Postgres, BigQuery, DBT.

$180,000 - $235,000 a year

Practice Questions

💡Technical Questions (3)
  • 1.Gridmatic relies heavily on large-scale weather forecasts and physical battery telemetry. How would you approach designing a data model and choosing a persistence strategy for high-frequency, large-volume timeseries data?
  • 2.Our stack includes DBT, BigQuery, and Python. Can you walk us through how you would use DBT to transform raw ingested energy data into reliable data products for the ML and optimization teams?
  • 3.As our first data engineer, you'll need to ingest data from various external grid APIs. How do you design a reliable ingestion pipeline that handles API rate limits, missing data, and ensures exactly-once processing using tools in our stack like Temporal or Kafka?
🎯Behavioral Questions (3)
  • 1.This is our first dedicated data engineering role, so you'll be stepping into a lot of ambiguity and taking ownership of critical datasets. Tell me about a time you built a data pipeline or architecture from scratch with minimal guidance.
  • 2.Working closely with ML and optimization teams is critical here. Describe a time when downstream data consumers (like data scientists) complained about data quality or schema changes. How did you handle it?
  • 3.Gridmatic operates in a low-ego, collaborative environment where rigorous thinking is core to our work. Tell me about a time you had to push back on a proposed technical solution or architectural decision because you felt it wasn't rigorous enough for the scale required.
🧩Situational Questions (2)
  • 1.It's 2 PM on a Tuesday, and the ML team alerts you that their forecasting models are producing anomalous results. You suspect an issue with the morning's weather data ingestion. How do you triage and resolve this?
  • 2.You need to create a new data product that merges fast-arriving battery telemetry with slowly changing grid market data, but the current ingestion schedules are causing latency. How would you redesign the pipeline to ensure the optimization team gets fresh, merged data with minimal delay?
