Twintual is seeking a founding engineer to own the platform end to end, collaborating with the CTO on architecture, integrations, and the infrastructure needed to keep Twintual reliable at scale. You will design and ship core features, own the Supabase/Postgres backend, run production workloads on Google Cloud (GKE), and manage deployments via Vercel and GitHub Actions. This is a high-autonomy, founding-role with direct access to the founding team.
