What We’re Looking For
We're looking for a software engineer who thrives at the intersection of data, software and infrastructure. You've worked in data-intensive environments and enjoy designing clean systems that move and transform data at scale. You’re someone who approaches data engineering as a software discipline — building reliable, tested, maintainable systems that empower others.
You'll work on building internal tools, pipelines, and APIs that support analytics, product features, and machine learning applications. You'll collaborate closely with both product and engineering teams to make our data infrastructure seamless, efficient, and delightful to use.
What will you be doing?
Own batch and streaming pipelines, including CDC feeds from operational databases into Snowflake, and make them reliable enough that other teams stop thinking about them.
Design the internal tools and APIs that make data usable for analytics, product features and machine learning.
Model and transform data in dbt so the warehouse is a source of truth people trust, not a pile of tables nobody can explain.
Decide how data should be stored and moved across CockroachDB, DynamoDB, Elasticsearch and Snowflake, and build the path between them.
Ship pipelines with the same standards as any production service: tests, CI/CD, containers, and observability through OpenTelemetry and Datadog.
Take a multi-component data project from scoping through to rollout, bringing other engineers into the design along the way.
What we’re looking for
Must-haves:
Strong software engineering fundamentals: tested, reviewed code with clean abstractions.
Proficiency in Python and SQL.
Hands-on experience building and running batch or streaming data pipelines in production.
Comfort across cloud-native infrastructure, ideally AWS, Kubernetes and Terraform.
Clear written and verbal communication, and a habit of sharing what you learn.
Nice to have:
Working experience with Snowflake and dbt.
Experience with CDC tooling or streaming systems.

What's the culture like at Primer?
We're building a culture where people can do their best work and be proud of the impact they have. You'll be working with people who are mission-driven, smart, and reflective, and who are genuinely invested in building exceptional products and delivering success for our merchants.
We work remotely, and have done since day one. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships through great remote working practices and thoughtfully designed face-to-face time, including workations, our annual company retreat, and access to co-working spaces across most major cities.
The work is challenging. Scaleups are a challenge, and building category-defining products is a challenge. But there's a meaningful difference between a challenge and a struggle. At Primer, the right challenge comes with the right support: strong onboarding, a collaborative environment, and a team that is genuinely invested in your success. It's never something you face alone.
