Principal Engineer

Overview

Principal Software Engineer on a lean, hands-on engineering team building the autonomous marketing platform for ecommerce, where AI agents find revenue opportunities, build campaigns and run them once the brand approves.

What you'll 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 what they need, and explain technical trade-offs in plain terms.
• Raise the bar for the team: review code, share what you know, and pick up the unglamorous work that helps everyone move faster.

What you'll need

• Built distributed systems that handle high throughput, partial failure, retries and recovery, and know where they tend to break.
• See the success of the team as their success.
• Leave code and systems better than they found them.
• Seek out trade-offs, not shortcuts, and turn disagreements into assumptions they can test.
• Break big problems into clear steps and pick the right-sized solution, not the most elaborate one.
• Explain technical ideas clearly to engineers and non-engineers alike.
• 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 is an extra plus.
• Comfort developing data pipelines and using ML.

Details

• Fully remote, working on Eastern Time (EST) hours.
• Reports to the CTO.
• Compensation: $235k to $285k base salary plus equity, depending on level and experience.
