Qentelli - Full Stack Developer

Fullstack Developer

Job Location : Hyderabad

Experience : 5 - 12 Years

Np : Immediate to 15 Days

Mode of Work : 5 Days office - Fulltime

Shift Timings : General shift

Platform Layers You'll Work Across :

- Experience : React, TypeScript, Optimizely, Apollo GraphQL

- API & Orchestration : Apigee, GraphQL, Auth0, Redis, Kafka

- Leadership Intelligence (AI) : OpenAI, Google Gemini, Neo4j, Snowflake, PostgreSQL, dbt, Airflow

- Systems of Record : Salesforce, PostgreSQL

- DevOps & Hosting : AWS/Azure, Kubernetes, Terraform, Datadog

What You'll Do :

- Own the full feature lifecycle architecture, implementation, code review, QA, deployment, and post-launch monitoring.

- Build responsive React/TypeScript frontends integrated with Optimizely; design Apollo GraphQL schemas and resolvers served through Apigee; build modular Node.js/NestJS backend services using Redis for caching and Kafka for event-driven workflows.

- Design and query PostgreSQL schemas (TypeORM/Prisma); collaborate on Snowflake pipelines and dbt models feeding the Leadership Intelligence layer.

- Integrate OpenAI and Google Gemini APIs for AI-powered discovery, recommendations, and matching; work with Neo4j graph data for relationship-driven insights.

- Use AI-assisted development workflows (pair programming, code generation, test scaffolding) to increase velocity without compromising quality; handle AI feature failures, timeouts, and token costs with a production mindset.

- Instrument features with PostHog and Datadog; design and run A/B experiments and feature-flag rollouts via Optimizely; use data to drive iteration.

- Contribute to architecture decisions, ADRs, and post-incident reviews; address performance bottlenecks across the stack (GraphQL resolvers, N+1 queries, frontend rendering, mobile time-to-interactive).

- Partner with product, design, the Lead Security Engineer, and DevOps to ensure features are secure, well-architected, and operationally sound from the start.

Required Qualifications :

- 5 - 7 years of professional software engineering experience shipping production-grade products end-to-end.

- Strong TypeScript/React skills (component architecture, state management, hooks, performance).

- Backend experience with Node.js and NestJS building modular, tested services.

- GraphQL experience (schema design, resolvers, subscriptions, Apollo client/server) and familiarity with API gateway patterns (Apigee or equivalent).

- PostgreSQL proficiency (query optimization, schema design, TypeORM/Prisma).

- Experience with Auth0 or equivalent identity platforms.

- Familiarity with Redis and Kafka (or similar) for caching and event-driven/message-queue patterns.

Nice to Have :

- Bachelor's degree in Computer Science, Engineering, or related field, or equivalent experience.

- Production experience with OpenAI, Google Gemini, or other LLM APIs (prompt engineering, rate limiting, fallback handling, cost management).

- Strong architectural thinking and clear technical communication; experience with high-autonomy, end-to-end ownership.

- Neo4j or other graph database experience.

- Snowflake/data warehouse experience with dbt or Airflow.

- Optimizely or similar experimentation/feature-management platforms.

- Salesforce integration experience.

- AWS experience (ECS, RDS, Lambda, S3, CloudWatch).

- Docker, Kubernetes, or Terraform.

- Testing with Vitest, Jest, or Playwright (unit, integration, e2e).

What YPO Offers :

- Meaningful scale, genuine ownership, and a mission worth caring about - building products used by some of the world's most accomplished leaders.

- Competitive compensation commensurate with experience, comprehensive benefits, and a collaborative engineering culture.
