Backend Developer

**Backend Developer — AI & Automation**
Remote · Philippines · Full-time · Mid–Senior (3+ years experience)

**About Priventix**

Priventix.ai is a fast-growing digital security brand — Antivirus, VPN, and Cloud Storage — sold to consumers across the US, UK, EU, and AU. We operate a high-volume affiliate and direct-response business built on AWS, and we're scaling fast.

We're looking for a backend developer who doesn't just build APIs — someone who uses AI tools natively as part of their workflow and can help us integrate and automate with OpenAI, Claude, and Gemini across our products, funnels, and internal operations.

**What You'll Work On**
- Build and maintain backend services, APIs, and microservices that power Priventix's subscription platform (license provisioning, billing, renewals, user accounts)
- Integrate AI APIs — OpenAI, Claude (Anthropic), Gemini — into product features, internal tools, and automated workflows (e.g. smart onboarding, threat summaries, support automation)
- Design and build AI-assisted automation pipelines for affiliate management, campaign reporting, and customer lifecycle triggers
- Connect and maintain third-party integrations: Stripe webhooks, AWS services, and vendor APIs (e.g. Cloudike, antivirus partners)
- Build internal tools and dashboards that pull data from our CRM, affiliate stack, and payment processors — with AI-powered summaries and alerts
- Write clean, well-documented, testable code and participate in code reviews
- Proactively identify where AI tooling can replace manual work and propose and implement those solutions
- Collaborate closely with the founder and team on product architecture decisions

- Hands-on experience with at least 2 AI APIs (OpenAI, Claude, Gemini)
- Strong command of Node.js or Python
- Experience building with AWS services
- Excellent written English — async-first team
