Tech Lead

About the Role

We're building scalable, secure healthcare products (EMR/HIMS, pharmacy, claims automation) used by hospitals, clinics, and insurers. You'll own end-to-end modules across MERN (MongoDB, , ) with an emphasis on solid system design, event-driven architecture (Kafka), and containerized deployments (Docker, Kubernetes). Basic DevOps know-how is expected.

Key ResponsibilitiesSystem Design & Architecture

·      Translate product requirements into HLD/LLD; choose datastore patterns; design REST/GraphQL APIs, event models, and caching strategies.

·      Apply microservices and event-driven patterns (saga/outbox, idempotency, back-pressure, retries, DLQs).

·      Evaluate trade-offs (CAP, consistency, throughput vs. latency) and document decisions via ADRs.

Backend / TypeScript)

·      Build REST/GraphQL services with Express or NestJS; write clean, modular, typed code.

·      Model schemas (Mongoose) and optimize MongoDB (indexes, aggregations, transactions).

·      Implement secure auth (JWT/OAuth2/OIDC), RBAC/ABAC, input validation, and rate limiting.

Frontend (React / )

·      Develop dashboards, forms, and real-time views; leverage SSR/ISR where appropriate.

·      Own state management (Redux Toolkit/Zustand) with resilient API integrations and error handling.

·      Ensure accessibility, responsiveness, and performance best practices.

Event Streaming (Kafka)

·      Design topics/partitions/keys; implement producers/consumers with proper retries and idempotency.

·      Manage schema evolution (Avro/JSON/Protobuf) and DLQ strategies; monitor lag and throughput.

Containerization & Delivery

·      Write efficient Dockerfiles (multi-stage builds); tune image size and startup time.

·      Create Kubernetes manifests/Helm values; configure probes, resource requests/limits, and ingresses.

·      Set up CI/CD pipelines (GitHub Actions/GitLab CI) with automated tests and zero-downtime deploys.

Quality & Observability

·      Define testing strategy (Jest, Supertest, Playwright) with meaningful coverage for core logic.

·      Implement structured logging, metrics, and tracing (ELK/EFK, Prometheus/Grafana, OpenTelemetry).

·      Own SLOs and alerting for critical paths.

Collaboration

·      Participate in grooming, estimations, and code reviews; mentor junior developers.

·      Work closely with product/design and clinical domain experts; document designs and trade-offs.

Must-Have Qualifications

·      3–5 years hands-on MERN development in production environments.

·      Strong + TypeScript; Express/NestJS and modular architecture.

·      React 18 / proficiency for complex, performant UIs.

·      System design fundamentals (CAP trade-offs, consistency models, data modeling, API design).

·      MongoDB expertise (indexes, schema design, performance tuning); Redis for caching/queues.

·      Kafka experience (producers/consumers, partitioning, retries, DLQs).

·      Docker (multi-stage builds) and Kubernetes basics (pods, deployments, services, ingresses, health probes).

·      CI/CD basics, Git workflows, and effective debugging in Linux containers.

·      Security hygiene: OWASP Top 10, secrets management, TLS, JWT validation via JWKS, and input sanitization.

Good-to-Have (Domain & Platform)

·      Healthtech/Insurtech exposure: EMR/HIMS, claims workflows, payer–provider integrations; knowledge of ABDM/ABHA, NHCX, or HL7 FHIR.

·      Identity & SSO: Keycloak/Auth0, OAuth2/OIDC/SAML; multi-tenant RBAC.

·      Data layer extras: PostgreSQL, Prisma; Kafka Connect/Debezium; Schema Registry (Avro/JSON/Protobuf).

·      Infra as Code (Terraform), Helm, Argo CD; cloud (AWS/GCP/Azure) and cost-aware design.

·      Realtime features (WebSockets), file/queue pipelines, media handling.

• ·      Performance profiling (Node/Chrome DevTools), Lighthouse, Core Web Vitals.
