Vibe Coder

Join Cult.fit to ship AI-first features. Strong with Cursor and Midjourney.

As a Vibe Coder at Cult.fit, you'll join a small, senior team building AI-native marketing products from the ground up. You'll work daily with n8n, Replit, ChatGPT to design, ship, and scale features that customers use every day. This is a high-ownership role — you'll have direct input on what we build and how we build it.

• Design, build, and ship production-grade AI features using n8n, Replit, ChatGPT
• Mentor junior builders and contribute to engineering standards
• Build retrieval, RAG, and agent pipelines that scale to thousands of concurrent users
• Architect end-to-end marketing workflows that integrate LLMs (OpenAI, Anthropic, Gemini) with internal systems
• Optimise inference cost, latency, and reliability across services
• Collaborate with product, design, and customer teams to translate business problems into AI solutions
• Own the full lifecycle of features — from spec, prototype, A/B test, to rollout

• Have shipped LLM-powered products to real users (not just prototypes)
• 4–7 years of experience as a Vibe Coder or in a closely related role
• Strong written communication — you can document decisions clearly
• Proficiency in Python, TypeScript, or both
• Strong hands-on experience with n8n / Replit / ChatGPT in real production environments
• Bias for shipping — comfortable owning ambiguous problems end-to-end
• Experience with prompt engineering, evals, and prompt-versioning workflows

• Comfort with Kubernetes, Terraform, or modern infra-as-code
• Open source contributions to AI / dev-tools projects
• Have written publicly (blog posts, talks, OSS) about AI engineering
• Built and operated agentic systems in production

• Work on problems that genuinely move the needle in Marketing
• Direct ownership — your code reaches real users within days, not quarters
• Learn from a team that has shipped at scale and built with n8n, Replit, ChatGPT from day one
• Tiny team, big surface area — wear multiple hats and grow fast
