Senior Data Engineer

We're growing our data engineering team to design and operate the production systems that make our machine learning and analytics work scalable, observable, reliable, and economical. This is a platform-ownership role: you're building the infrastructure a petabyte-scale data platform runs on, not executing tickets handed down from another team. You'll work on problems like: Designing and operating production data pipelines across a layered (bronze/silver/gold) data platform: sourcing, cleansing, and transforming data at scale Solving incremental sync and stream processing as data volume and account count grow — a real, unsolved scaling problem for us today Building regional data architecture that respects data residency and PII boundaries (e.g., data belonging to a region can't simply be centralized into one global store) Designing the production systems, orchestration, and deployment mechanisms that turn Data Science's models and analysis into durable, monitored, reliable pipelines Where this role starts and ends: Data Science owns problem formulation, features, model and scoring logic, evaluation, and model performance. You own the pipeline infrastructure, orchestration, deployment mechanisms, observability, scalability, and operational reliability that put their work into production. The primary ownership is clear, but you'll work together across that boundary when production issues span model and platform. This is an individual contributor role with substantial ownership of the platform. It does not include people-management responsibilities. Must-Haves: 5+ years designing and operating data pipelines in production at scale Experience with batch and stream data processing, including incremental/streaming architectures Strong Python and production-grade software engineering practices (testing, code review, version control, monitoring) Demonstrably strong SQL Experience with ETL/ELT pipeline design and orchestration Nice-to-Haves: Experience with regional/multi-region data storage and data residency constraints Parallel dataframes (Dask, Spark, or similar) API design/implementation (microservices, REST, etc.) Cloud environment experience (GCP or AWS), Docker/Containers, Kubernetes Machine learning deployment or serving experience Why Should You Apply? Own the platform problem that determines how fast and how reliably ActivTrak's ML and analytics can scale Meaningful scaling challenges: incremental/streaming processing, regional data residency, and petabyte-scale data across hundreds of millions of events per day Small, senior team with real ownership and visibility to leadership Work environment Position is remote within US Minimal travel Limited physical demands This is an incredible opportunity to embark on an exciting journey with a dynamic, VC-backed company. If you have a proven track record of creative thinking, a drive for learning, and a deep commitment to collaboration, we want to talk to you! ActivTrak is an equal opportunity employer.
