At GrowthX, we've redefined what AI-powered growth means for modern marketing teams. Since launching in 2024, we've grown from concept to eight-figure annual revenue. To date, we've raised a $12M Series A led by Madrona Venture Group and we partner with 50+ companies ranging from high-growth startups to industry leaders like Surge AI, Loveable, Webflow, Ramp, Superhuman, Strapi, Abnormal Security, and Homebase.

We've built something different—what we call "service-as-software." Instead of handing you tools and leaving you to figure them out, we deliver complete outcomes. Our platform combines sophisticated AI workflows with expert human oversight to create, distribute, and optimize content that drives real business results.

Our philosophy is simple: AI should serve experts, not replace them. We're not just building software. We're building the growth infrastructure that marketing teams wish they'd always had.

We are seeking a Staff full-stack developer with a strong product mindset and high standards for user interface design. Our stack includes React (TypeScript with Tailwind/Shadcn) and Ruby on Rails (Rails experience is a plus but not required).

Most of your time will likely be spent working full-stack in internal platform, which supports everything from SEO tools to AI-powered text editing – but at an early stage team, the needs might vary.

Being an AI-native company, we expect every team member to embrace AI to boost productivity. Familiarity with tools like Cursor is essential, but we are happy to provide guidance here.

This is a fully remote role, but we do ask for at least 4 hours of overlap with US Pacific Time—during reasonable work hours.

• Collaborate with our Client Ops team to design and deliver full stack solutions supporting internal teams.

• Build and maintain features using React (TypeScript) and Ruby on Rails, enhancing internal workflows and tools.

• Turn ideas from whiteboard sketches into fully functional, production-ready features with high-quality UX.

• Use tools like Cursor to accelerate development, streamline maintenance, and optimize workflows.

• Focus on creating intuitive and visually appealing interfaces that deliver an exceptional user experience.

• Design features with strong attention to usability, creating clear and enjoyable user interfaces.

• Write concise, effective UI copy.

• Support marketing initiatives with small coding projects as needed.

• Help create and maintain our AI Workflows (no experience needed here, but willing to learn is a must).

We’re looking for someone with:

• Proven Experience: Strong full stack skills, including building web applications using React and Ruby on Rails (or Python), working with PostgreSQL, and familiarity with frontend frameworks like Tailwind or Shadcn.

• Passion for AI: Excitement for GenAI, LLMs, and tools like Cursor.

• Good Design Taste: An ability to create user-friendly interfaces independently, focusing on clarity and usability.

• Ownership: A self-starter mentality, capable of managing projects and priorities with minimal supervision.

• Collaborative Mindset: A team player who thrives on proactive communication and constructive feedback.

• Communication Skills: Clear and proactive communication skills, essential in a remote environment, with the ability to keep the team informed and aligned.

• Pragmatic Approach: A focus on practical, impactful solutions, avoiding over-engineering or unnecessary debates.

• Project Management: Excellent organizational skills, keeping your to-dos and tickets up to date, and ensuring team awareness of progress and blockers.

This role is more suited for someone that have created entire projects on their own, even if just as a side-projects, than someone that prefers a lot of structure or guidance.
