Role Summary
We’re Wellness Coach—a B2B wellness platform. We’re hiring a dedicated, AI-first full-stack engineer with a backend emphasis who owns features end-to-end across Node.Js / TypeScript / NestJS (primary) and React / TypeScript (secondary). You’ll ship with strong CI / CD , uphold SonarQube quality gates, and drive scaling & optimization across the stack.
Responsibilities (backend-heavy)
- End-to-end delivery : requirement Gathering → design → estimate → implement → test → deploy → observe → iterate.
- Backend (primary – Node.Js / TS / NestJS) :
- Design and deliver REST APIs;
enforce OAuth / JWT auth,RBAC, and rate limiting.
Build high-throughput services with caching (Redis), message queues / streams (RabbitMQ / Kafka), and webhooks.Engineer resilient, observable microservices (retries, idempotency, circuit breakers, backpressure).Data :Schema design & migrations ( PostgreSQL / MySQL / MongoDB );indexing, query tuning,partitioning.
Thoughtful use of Redis for caching, locks, and ephemeral data.Frontend (supporting – React / TS) :Implement and maintain accessible, responsive UIs;routing / forms;pragmatic state mgmt (React Query / Zustand / Redux).
CI / CD :Build → test → scan → SonarQube quality gate → deploy ( blue / green / canary ) with automated rollbacks.Security & quality :SAST / DAST, dependency health, OWASP practices, meaningful code reviews, secret hygiene.Observability :Logs / metrics / traces (Sentry, Grafana / Prometheus), actionable alerts & SLOs.Scaling & optimization :Improve throughput / latency / memory, tune Node event loop, connection pooling;SSR / Next.Js perfwhere relevant;capacity planning & cost control.
AI-first workflow :Use Cursor / Copilot / LLM reviewers for coding, tests, and PR feedback with prompt hygiene, determinism, and secret safety.Working Hours & Collaboration
Maintain 4–5 hours daily overlap with the US team, typically 2 : 00–11 : 00 PM IST (Mon–Fri) .Participate in sprint rituals, design reviews, incident / launch windows during the overlap.Minimum Qualifications
5–10 years building & shipping production systems with Node.Js (TypeScript) and NestJS ;strong React (TypeScript) proficiency.
Proven scaling & optimization achievements : DB / query tuning, effective caching / CDN, queueing / streaming, horizontal scaling, Core Web Vitals awareness for user-facing flows.Hands-on with Docker , CI / CD (GitHub / GitLab Actions), and a major cloud ( AWS / GCP / Azure ).Solid SonarQube experience (quality profiles, coverage gates, security hotspots).Testing depth : Jest / Vitest , React Testing Library , Playwright / Cypress ;testcontainers for integration tests.
Excellent ownership, documentation, and cross-functional collaboration.Nice to Have
Fastify, Next.Js, GraphQL, WebSockets / event-driven designs.IaC ( Terraform / CDK ), GitOps / ArgoCD, feature flags, experimentation (Mixpanel).Node profiling ( clinic.Js ), cost / perf tuning, accessibility (WCAG).CI / CD & Quality (Expectations)
Branching : trunk-based or GitFlow with protected main;mandatory PR checks.
Pipelines include : type-check, lint, unit → integration → e2e tests, SonarQube scan , SCA (Dependabot / Snyk), Docker build, deploy, smoke checks, auto-rollback hooks.Quality bar :Test coverage ≥ 80% overall ( ≥ 90% on core paths).0 blocker issues in SonarQube;no new critical vulnerabilities / smells.
Frontend preview builds meet perf budgets (LCP / TTFB / CLS).Definition of Done
CI green (type-check, lint, tests);SonarQube gate passed .
Telemetry & alerts configured;runbook / README updated;ADR / OpenAPI updated as needed.
Feature flags set for safe rollout;migrations and rollbacknotes included.
30 / 60 / 90 Success Plan
15 days : Local env ready;ship a small backend-led feature behind a flag;SonarQube green;dashboards wired.
45 days : Lead a medium backend feature;improve a pipeline step(caching / parallelism);add alert + runbook.
60 days : Own a service / domain;propose an ADR;measurably raise reliability / perf for a critical path.
