About the Role Were looking for a Senior Full-Stack Engineer who can own technical direction on a production multi-tenant SaaS platform. Youll work across backend, frontend, cloud, and CI/CD - designing solutions, mentoring experts on the team, and shipping reliable features end to end. Solid communication and hands-on technical leadership are as important as coding depth.

What Youll Do

Lead design and implementation across a TypeScript monorepo (Fastify API, Next.js web UI, shared packages) using Domain-Driven Design. Build and evolve scalable backend services with Fastify, Azure Functions, MongoDB/Cosmos DB, and Azure storage/queue services. Deliver rich frontend experiences with Next.js, React, TypeScript, TanStack Query, and modern UI patterns. Own and improve Azure DevOps CI/CD pipelines, deployments, environments, and release quality for API, web, and async workers. Design multi-tenant data models, APIs, permissions, and integrations (including Azure AD B2C / MSAL auth). Propose and drive technical solutions for complex product problems - architecture trade-offs, performance, reliability, and observability.

Partner with product and engineering experts: code reviews, design discussions, mentoring, and clear written/verbal communication.

Ensure production readiness: testing, monitoring (OpenTelemetry), Dockerized services, and operational support.

What Were Looking

For 7+ years of full-stack software development, with clear senior/lead ownership of systems in production.

Strong

TypeScript/Node.js expertise; hands-on experience with Fastify (or similar Node frameworks) and Next.js/React.

Solid experience with Azure cloud services: App/Functions hosting, Storage (Blob/Queue), identity (Azure AD B2C / Entra),



and related SDKs. Hands-on Cosmos DB (MongoDB API) or MongoDB - modeling, indexing, query performance, and multi-tenant data design.

Experience with Azure DevOps pipelines, CI/CD, and shipping services safely across environments. Comfort with Domain-Driven Design, REST APIs, shared type contracts, and typed monorepo workflows (e.g. Turborepo/npm workspaces).

Ability to lead technical decisions, communicate clearly with stakeholders, and work effectively with a team of specialists. Strong problem-solving, code quality, testing discipline, and production support mindset. Full-time availability and willingness to take end-to-end ownership of features and platform improvements.

Nice to Have Experience with Azure Web PubSub, Communication Email and similar Azure integrations. Familiarity with async/background job architectures (Azure Functions + queues). Exposure to media/workflow-heavy products (video/PDF processing, real-time UI, 3D/canvas tooling).

Observability experience (OpenTelemetry, metrics, tracing, logging). Docker, infrastructure-as-code, or multi-environment Azure operations. Prior to mentoring, tech lead, or architecture ownership in a SaaS/multi-tenant product.
