What we're looking for 

A fast-growing US-based creative advertising agency is looking for a Full-Stack Developer to architect and build the internal platform that powers how they create, strategise, and operate. This is a high-autonomy, high-impact role where you will own the technical direction of systems used daily across the entire team. If you thrive in fast-paced, founder-led environments and want your engineering work to directly reshape how a creative business runs, this is for you.

What You’ll Be Doing

• Design and build AI-powered internal tools across the full stack, including frontend interfaces, backend services, data pipelines, and API integrations.
• Build creative intelligence systems that ingest performance data (Meta, TikTok, Google) and surface actionable insights for strategy teams.
• Develop production pipelines that take a creative brief through AI-assisted asset generation (image, video, copy) to a review-ready output.
• Integrate and orchestrate generative AI models (Claude, OpenAI, Runway, FLUX, and others) as structured components of real production workflows.
• Connect and automate internal tools, including Slack, Notion, Google Drive, and After Effects, to reduce manual overhead across the team.
• Collaborate directly with strategists, creative directors, and producers to identify and prioritise the highest-leverage software interventions.

Requirements

• 4+ years of full-stack engineering experience with a portfolio covering frontend, backend, and data work.
• Strong Python, JavaScript, and TypeScript experience.
• Proven experience building production systems on top of LLM APIs or generative AI models, not just consumer tools.
• Experience in architecting scalable systems and owning the full technical lifecycle from design through to deployment and iteration.
• Track record of self-directed delivery, scoping, and shipping non-trivial projects without heavy management scaffolding.
• Clear communicator who can translate technical decisions into plain language for non-technical teammates.

Nice to Have

• Experience with the Meta Marketing API or Ads Library for programmatic creative data extraction.
• Hands-on work with video and image generation models (Runway, Kling, FLUX) in production contexts.
• Background in performance marketing, creative agencies, or ad-tech environments.

Benefits

• Competitive USD salary
• 100% remote work
• Paid Time Off
• US festive days
