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.

• Comfortable navigating cloud-native ecosystems (AWS, K8s, Terraform)

Mindset & Collaboration

• Clear and thoughtful communicator (written and verbal)

• Detail-oriented

• Team player (“our code,” not “my code”)

• Eager to learn and share

• Adaptable — comfortable with ambiguity and shifting priorities

• You enjoy working in an office-setting, we are remote-first and always will be!

• You are not comfortable with shifting context and navigating ambiguity

• You don’t enjoy testing your code, we have no testers or QA’s here at Primer

• 30 minute call with a Talent Partner

• 45 min Hiring Manager interview

• Take home task followed by a 60 minute interview

• 60 minute final stage interview

Unfortunately we are unable to offer sponsorships or relocation packages at this time.

We’re building a culture where people can come and do their best work and enjoy it. We want our people to be proud of the impact that they have at Primer, and of the work that they are doing. You will be working with a team of people who are mission-driven, smart, and reflective, and who are invested in building exceptional products and delivering success for our merchants (and we also know how to have fun along the way).

We work remotely. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships with each other through great remote working practices and thoughtfully designed face-to-face time together. Our heads-together time comes in the form of workations, our annual company retreat, and co-working space access worldwide.

Finally, let’s go ahead and say it. The work that we do is challenging. Startups are a challenge, building category defining products is a challenge. You should be prepared for a challenge at Primer. But, there’s a big difference between a challenge and a struggle. The key difference is that the right challenge comes with the right support structures, an acceptance that not everything always goes to plan, a collaborative environment, and a great team around you. It’s never a challenge that you will face alone.

• We are fully remote

• Competitive share options

• Uncapped holiday, with 25 days minimum to be taken
