Principal Backend Architect
SaaS · MVP → Series B
Designs modular NestJS backends for SaaS scaling from MVP to Series B. Clean Architecture, database optimization, full DevOps ownership.
00 Node.js · Backend
Hire a Node.js developer who builds backends that scale— not ones you rebuild in 6 months.
Dedicated Node.js engineers for APIs, microservices, and real-time systems. Embedded in your team full-time, not borrowed from a marketplace.
01 · What this role does on your team
Embedded in your team, owning real production work.
- Designs and builds REST and GraphQL APIs with Express, Fastify, or NestJS
- Architects microservice systems with message queues (RabbitMQ, Kafka, SQS), event-driven patterns, and service mesh
- Manages databases — PostgreSQL, MongoDB, Redis — including schema design, query optimization, and migration strategies
- Implements authentication, authorization, and session management (JWT, OAuth2, RBAC)
- Writes automated tests, configures CI/CD pipelines, and owns deployment to cloud environments (AWS, GCP)
02 · What we vet for
We accept the top 2% — and we vet specifically.
-
Production Node.js backends serving real traffic — not Express hello-world tutorials
-
Understanding of the event loop, non-blocking I/O, and when Node.js is the wrong tool (CPU-bound work)
-
Database design skills — normalized schemas, indexing strategy, query performance tuning
-
NestJS or equivalent framework experience for structured, maintainable backend architecture
-
Ability to debug production issues under pressure — memory leaks, connection pool exhaustion, race conditions
03 · Stack & tools
Production tooling, not tutorial setups.
- Node.js
- NestJS
- Express
- Fastify
- TypeScript
- PostgreSQL
- MongoDB
- Redis
- RabbitMQ
- Kafka
- Docker

05 · Compliance note
Built for regulated environments.
Node.js backends in HealthTech handle PHI through API endpoints — every route needs audit logging, access control, and encrypted data transmission. Our backend engineers implement HIPAA-compliant data flows as default architecture, not as a retrofit.
06 · Pricing
Transparent monthly rates. No hidden fees.
Mid-Level Node.js developers from $2,750/mo. Senior from $3,500/mo. Full rate card with all six tiers.
