About Triba Health

Triba Health is a danish company with operations in South Africa. We are a mission to revolutionize Type 2 Diabetes management through a scalable, white-labeled, multi-tenant health platform. We are designing a system that can dynamically adapt to different B2B partners while maintaining high performance, security, and flexibility.

We are looking for a Senior Backend Engineer to take ownership of multi-tenancy architecture, backend scalability, event-driven workflows, and seamless integrations with third-party services. This role requires deep experience in tRPC, Node.js, PostgreSQL (Supabase), and event-driven backend design.

Your role:

You will play a critical role in defining our backend architecture, optimizing data flows, and ensuring seamless multi-tenant operations. Your work will decouple frontend and backend, allowing for clear contracts between services and efficient scaling.

You will be working with tRPC, Apollo GraphQL, Vercel, Supabase, PostHog, Customer.io, and event-driven backend processes (e.g., Inngest).

What you'll be doing:

Multi-tenancy & white-labelling

  1. Implement multi-tenant architecture in tRPC with dynamic tenant-based data access
  2. Use Supabase Row-Level Security (RLS) to enforce tenant data isolation and optimize permission handling.
  3. Build a white-labeled backend system that allows dynamic branding and configurations per partner.
  4. Optimize API contracts between the frontend and backend, ensuring React Native & Next.js frontends communicate efficiently.

Backend data flow & BI integrations

  1. Set up data pipelines to sync analytics to PostHog and customer engagement tools (Customer.io).
  2. Ensure data is tracked properly across the user journey for behavioral insights and nudging workflows.
  3. Work with the UX and product teams to implement nudging logic for improved user engagement.

Third-party integrations & async event-driven workflows

  1. Design async backend processes with Inngest (e.g., user actions triggering follow-up events).
  2. Integrate GetStream (chat & community features), calendar scheduling tools, and other external services.
  3. Implement event-driven backend processes to handle batch processing, real-time analytics, and background jobs efficiently.
  4. Optimize Vercel hosting, Supabase performance, and CDN configurations for high scalability and low latency.
  5. Implement OAuth, JWT authentication, and security best practices to ensure data privacy and compliance.
  6. Improve caching strategies, database indexing, and API performance to reduce response times.

What we are looking for:

Required skills:

  1. Solid proficiency in TypeScript, ensuring strict typing across backend logic.
  2. Strong expertise in Node.js, with a deep understanding of backend service architecture.
  3. Expertise in authentication & security (OAuth, JWT, role-based access control).
  4. Experience working with event-driven architectures (Inngest, queues, or async workflows).
  5. Strong experience in third-party API integrations (GetStream, calendar tools, email automation).
  6. Hands-on experience with Vercel hosting & optimizing serverless deployments.
  7. Understanding of frontend/backend contracts and how to decouple frontend & backend development.

Bonus Skills:

  1. Solid understanding of TRPC APIs
  2. Experience with Apollo GraphQL & MCP (Microservices Control Plane) servers.
  3. Familiarity with React & React Native, enabling efficient collaboration with frontend teams.
  4. Knowledge of caching strategies & performance optimizations for large-scale apps.

Build a cutting-edge, scalable health platform with modern tech.

Own backend architecture decisions and drive multi-tenancy design.

Fully remote & flexible work – results-driven, no micromanagement.

High-impact role in a growing digital health company.

Work with a passionate, fast-moving team that values autonomy & innovation.

The Hiring process:

  1. Application Review – Screening of your resume & GitHub portfolio.
  2. Initial Chat – 30-minute discussion on your experience and technical background.
  3. Technical Task – Short, real-world backend challenge.
  4. Final Interview – Deep dive into your approach to multi-tenancy, event-driven systems, and backend scalability.
  5. Offer & Onboarding – Join Triba Health and help shape the future of digital health
