Founding Engineer

We need a senior engineer who can own the platform end to end. You will work directly with the CTO on product architecture, integrations, and the infrastructure that makes Twintual reliable at scale. This is not a ticket-taking role. You will decide what gets built, how it gets built, and ship it.

The role

What you will actually do

• Design and build channel integrations (Slack, WhatsApp Business, Teams, Telegram): OAuth flows, webhooks, token refresh, rate limits, the lot.
• Own the Supabase backend: schema design, RLS policies, edge functions, performance tuning.
• Run production workloads on Google Cloud (GKE) for AI pipelines and long-running jobs. Keep costs sane, keep things observable.
• Manage the Vercel dev and web environments, and the deployment path from dev to production.




• Ship FlutterFlow features and extend them with custom code when FlutterFlow hits its limits.
• Set up the engineering foundations: CI/CD on GitHub Actions, monitoring, error budgets, on-call rotation.
• Hire and mentor the next engineers. You will be the technical bar for the team.
• Talk to pilot customers when a bug or an edge case needs a real answer.

Reports to

CTO, Mat Bertrandy

Day 90 goal: Slack and WhatsApp integrations in production, Supabase schema clean and well-indexed, GKE workloads observable and cost-controlled, new engineers onboarding from your docs.
