Principal Engineer

The role

You will design, build and run systems that send high volumes of email for many brands. You will also ship AI agents that plan, create and run marketing campaigns, from prototype to production.

What you will do

• Design, build and run systems that send high volumes of email for many brands, reliably and on time.
• Ship the AI agents that plan, create and run campaigns, from first prototype to production.
• Own what you build from first commit to long after launch, including keeping it healthy in production.
• Turn fuzzy problems into small, shippable steps, then build to learn what's next.
• Work with teammates outside engineering and with brands to understand their needs.
• Explain technical trade-offs in plain terms.
• Review code, share knowledge and do the unglamorous work that helps the team move faster.

Required qualifications

• Have built distributed systems that handle high throughput, partial failure, retries and recovery.
• Know where distributed systems tend to break.
• See the success of the team as their own success.
• Break big problems into clear steps and choose the right-sized solution.
• Explain technical ideas clearly to engineers and non-engineers.
• Enjoy deep technical discussions with other low-ego engineers.
• Want to keep growing while helping others level up.
• Are curious about the domain and the problem, not just the code.

Nice to have

• Worked at a startup and like the pace and breadth that come with it.
• Experience in email or marketing tech, such as deliverability, sending infrastructure or campaign tooling.
• Deep knowledge of e-commerce.
• Experience with Shopify.
• Comfort developing data pipelines and using ML.

Benefits

• Equity is part of compensation.

Before you apply

• Engineers from any modern stack who are open to learning are considered even if their experience does not match exactly.
