Senior Full-Stack Engineer — Backend-Focused

Remote · Platform Engineering · Full-time · 4–5 years experience

About the Role

We're a healthcare technology company building a multi-tenant case-management platform that orchestrates

complex clinical, payment, and communication workflows. You'll build backend services that power the product

— a TypeScript GraphQL API on Node.js, backed by PostgreSQL/Prisma and deployed on Google Cloud,

integrating a broad ecosystem of third-party healthcare, payment, and communication providers.

This is a senior, high-ownership role on a remote-first team. You'll design systems, lead complex integrations,

mentor engineers, and influence our architecture as we scale.

What You'll Do

• Design, build, and operate backend features on our Node.js + TypeScript platform using Express + Apollo

GraphQL in a modular-monolith architecture.

• Model and evolve a large, multi-tenant data layer with Prisma 7 on PostgreSQL (including read replicas),

with attention to performance, indexing, and data integrity.

• Build and harden third-party integrations — payments (Stripe, NMI), communications (SendGrid, Twilio),

CRM (HubSpot), scheduling (Calendly), and healthcare systems (Dosespot, pharmacy/consult-provider

APIs).

• Design event-driven and asynchronous workflows using Google Cloud Pub/Sub, scheduled jobs (App

Engine Cron), and Cloud Functions — for payment retries, follow-ups, escalations, and batch processing.

• Implement secure authentication and RBAC (Firebase Admin, JWT, OTP flows, granular permissions) in a

multi-tenant, compliance-sensitive context.

• Work with GCP services — App Engine, Cloud Storage, BigQuery, Document AI, Secret Manager — and

contribute to CI/CD via GitHub Actions and Prisma migration pipelines.

• Make full-stack changes when needed — wiring up the Vue 3 / Apollo frontend to ship a feature completely.

• Write robust tests with Vitest + Supertest and Firebase emulators; ensure reliability, observability

(Winston/Cloud Logging), and safe rollouts.

• Mentor engineers, lead design discussions, and own systems end-to-end in production.

What We're Looking For

• 4–5 years of professional backend or full-stack engineering experience, with a track record on

medium-to-large-scale production systems.

• Strong Node.js + TypeScript expertise and solid API design skills (GraphQL strongly preferred; strong

REST background welcome).

• Deep relational database experience — schema design, query optimization, migrations — ideally with

Prisma/PostgreSQL or comparable ORMs.

• Experience building and maintaining complex third-party integrations and webhook-driven systems,

including payments.

• Familiarity with cloud infrastructure (GCP preferred; AWS/Azure transferable), async messaging/queues,

caching (Redis), and CI/CD.

• Solid grasp of authentication, authorization (RBAC), and security best practices.

• Enough frontend competence to contribute to a Vue/React + GraphQL client when a feature demands it.

• Demonstrated ability to own systems independently, take responsibility for reliability and on-call quality,

and reason about scale and trade-offs.

• Excellent written and verbal communication — essential for our remote, async culture.

• Leadership qualities: you mentor others, drive technical design, and raise engineering standards.

Nice to Have

• Experience with Pub/Sub, BigQuery, Document AI, or other GCP-native services.

• Background in healthcare, fintech, or regulated/compliance-sensitive domains (HIPAA awareness a plus).

• Experience with multi-tenant SaaS architecture and data isolation.

• Familiarity with AI/LLM integrations (Claude, OpenAI, vector DBs like Pinecone).

• Experience scaling systems with rate limiting, observability, and performance tuning.

Development and Customization:

Build and customize Frappe modules to meet business requirements.

Develop new functionalities and troubleshoot issues in ERPNext applications.

Technical Support:

Participate in code reviews for quality standards.

Continuous Improvement:

Stay updated with Frappe developments and optimize application performance.

Skills Required:

Proficiency in Python, JavaScript, and relational databases.

Knowledge of Frappe/ERPNext framework and object-oriented programming.

Experience with Git for version control.

Strong analytical skill

Design and develop scalable web applications using MEAN/MERN stack.

Build & optimize AI/LLM workflows using LangChain or LangGraph.

Implement vector storage & semantic search using FAISS / Pinecone / Chroma / Milvus.

Build APIs, microservices, and integration layers.

Optimize application performance and ensure code quality.

Collaborate with cross-functional teams (product, design, backend, DevOps).
