Oh is building the OpenAI of the spicy content industry. We’re a company at the forefront of the generative AI revolution, combining cutting-edge models developed in-house, with proprietary data sources and distribution via our consumer platform, OhChat, and market-leading API.

OhChat now has over 250,000 users and hosts Digital Twins of household names, and our API is integrated into some of the biggest platforms in the adult content space, distributing those Digital Twins across the internet. Backed by $10M in venture funding, we’re quickly establishing ourselves as the dominant, essential layer for adult creators and platforms to adopt AI.

Our aim is for OhChat to be the leading “AI OnlyFans” platform and our API to be the go-to for all adult platforms wanting the technology and our Digital Twins’ IP, in a combined package - ultimately we aim to be the most dominant AI player in the entire adult industry, ahead of expansion to adjacent industries such as companionship and more general creator industry.

We’re looking for a MarTech & AI Automation Developer to build the automation backbone of our marketing engine — and lay the technical groundwork for AI agent integration across the business. Starting in marketing and growth, your work will scale into other departments as we build toward a fully agent-enabled organisation.

This role is part growth engineer, part automation architect, part AI agent integrator — with a clear path to own how intelligent automation gets rolled out company-wide. This is a highly cross-functional role, working closely with Growth, Marketing, Product, and Engineering to build, connect, and optimise the tools and workflows that power our customer journey, from first touch through to loyal, high-value users.

• Architect and implement marketing automation workflows using tools like Customer.io, Make.com, or HubSpot with AI agent triggers (e.g. auto-responders, AI DMs, onboarding guides).

• Integrate AI agents (e.g. GPT-4o, Claude, Gemini) to support lifecycle touchpoints from lead capture and email composition to campaign reporting and churn prediction.

• Build and maintain intelligent workflows across paid, organic, and lifecycle channels

• Help prototype and deploy lightweight internal AI agents using frameworks like LangChain, CrewAI, or Autogen.

• Define data flows and context windows that allow agents to act intelligently across CRM, analytics, support, and campaign data.

• Connect AI agents to company tools (via Zapier, Make, custom scripts, or native APIs).

• Set up and manage marketing event tracking across all surfaces (e.g. Segment, PostHog, Google Tag Manager, Mixpanel).

• Own end-to-end attribution, funnel tracking, and customer journey analysis — including SEO and content performance monitoring.

• Build dashboards and reports that support fast experimentation and insight-driven decisions.

• Extend and customise CRM, CMS, landing page tools, and campaign platforms (e.g. Webflow, Unbounce, Looker Studio).

• Create internal tools and helper scripts in Python or Node.js to automate workflows and reduce manual effort for go-to-market teams.

• Maintain and evolve API, webhook, and data pipeline integrations across all marketing systems.

• Work closely with Product, Engineering, and Growth to ensure AI agents and automations have the right access, triggers, and feedback loops.

• Act as the internal champion for automation-first thinking across departments.

• Help define the roadmap for broader AI agent rollout to other functions (e.g. support, operations, creator onboarding).

• Customer.io, HubSpot, ActiveCampaign, or similar

• Make.com (Integromat), Zapier, Pipedream

• Segment, RudderStack, PostHog, Amplitude, Mixpanel

• GA4, Looker Studio, Google Tag Manager

• Webflow, Unbounce, basic HTML/CSS/JS

• LangChain, CrewAI, AutoGen, Semantic Kernel

• Lightweight orchestration of agents via Make or CLI

• REST API integration, webhook chaining

• Python or Node.js scripting for workflow logic

• Git for version control

• 2–3 years’ experience in MarTech, automation, or technical growth roles.

• Strong knowledge of CRM customisation and automation workflows.

• Experience working with APIs, event tracking, and data pipelines.

• Strong interest or experience in AI tools, agent architecture, or prompt engineering

• Passion for optimisation, scalability, and measurable results.

• Excellent problem-solving skills and the ability to work cross-functionally in a fast-moving environment.

• Shape the growth infrastructure of a next-generation global AI platform.

• Work on cutting-edge marketing and automation technologies that redefine how users discover and interact with AI-powered characters.

• Join a diverse, ambitious, and creative team pushing technical and creative boundaries.
