Backend Engineer - Node.js/Python

About the Role :

We are seeking a skilled Backend Engineer to design, build, and optimize the core services that power
our SaaS platform. The ideal candidate has strong expertise in Node.js and Python, database
performance tuning, and cloud-native deployments on Azure. You will work closely with frontend,
DevOps, and product teams to deliver secure, scalable, and reliable backend systems.

Key Responsibilities :

Core Backend Development :

- Build scalable APIs using Node.js (REST & GraphQL).

- Develop microservices and user-deployable logic in Python, including AI/ML service integrations.

- Implement robust API security with OAuth2, JWT, and role-based access control.

Database Expertise :

- Ensure consistency, transactions, and scalability in distributed database setups (including sharding).

- Apply caching strategies (Redis, in-memory stores) for high-performance applications.

Cloud & DevOps (Azure) :

- Deploy and manage services on Azure App Services, AKS (Kubernetes), Functions, Service Bus,
and Event Grid.

- Work with CI/CD pipelines (Azure DevOps/GitHub Actions) to automate deployments.

- Manage secrets, configurations, and environments with Azure Key Vault and Config Servers.

Architecture & Scalability :

- Design and implement event-driven and microservices architectures using queues and async
processing.

- Build multi-tenant SaaS backends with isolation, rate limiting, and usage metering.

- Apply distributed systems knowledge to balance latency, reliability, and fault tolerance.

Testing & Reliability :

- Implement observability practices: structured logging, metrics, tracing (Azure Monitor, ELK,
OpenTelemetry).

- Debug and profile backend performance to ensure system stability.

Collaboration & Agile Practices :

- Contribute to CI/CD workflows and iterative delivery.

- Participate in code reviews, architectural discussions, and Agile ceremonies.

Qualifications :

- 810 years of backend development experience in SaaS or large-scale applications.

- Proficiency in Node.js (REST & GraphQL) and strong working knowledge of Python.

- Strong expertise in MongoDB and caching systems (Redis).

- Experience deploying workloads on Azure (App Services, AKS, Functions).

- Familiarity with CI/CD, Docker, and Kubernetes.

- Strong testing, debugging, and observability skills.

- Good understanding of distributed systems, microservices, and event-driven architecture.

- Excellent problem-solving and collaboration skills.

What We Offer :

- Exposure to modern architectures (microservices, event-driven systems, AI/ML integrations).

- Collaborative and growth-oriented work environment.

- Competitive compensation and benefits.
