About the role

Our AI creative platform helps marketing teams produce ad copy, product descriptions, email subject lines, and social content at scale. The platform has 18,000 users and generates 2 million content pieces per month. Behind the scenes, it is a collection of prompt chains, output validators, style guides, and brand voice enforcements that turn a single brief into on-brand content variants. You'll be the third engineer on the content generation team, helping build and maintain the prompt engineering infrastructure. That means: new content templates when clients request formats we don't yet support, prompt optimization when output quality drifts, output validation that catches off-brand or factually wrong content before it reaches users, and A/B testing infrastructure for comparing prompt variants. You'll learn a lot about prompt engineering, LLM APIs, and production AI systems in this role. The senior engineers will teach you what they know, and there's a clear path to taking ownership of specific content verticals within a year.

Fully remote.

Responsibilities

  • Build new content generation templates for ad copy, email, and social formats
  • Maintain and optimize existing prompt chains when output quality regresses
  • Implement output validation to catch off-brand or factually problematic content
  • Build A/B testing infrastructure for comparing prompt performance
  • Monitor content quality metrics and surface issues to senior engineers
  • Document prompt engineering patterns and maintain a template library

Requirements

  • 1+ year of Python development experience
  • Basic familiarity with LLM APIs like OpenAI or Anthropic
  • Interest in language, writing, and content marketing domains
  • Attention to output quality and ability to evaluate what good looks like
  • Clean code practices and willingness to write tests

Benefits

  • Fully remote
  • Health and dental
  • $1,500 learning and tools budget
  • Mentorship program
  • Clear promotion path with semi-annual review cycles
