Hot Skills 2026

Skills with the fastest-growing presence in Indian JDs right now

1

GitHub Copilot

AI Dev Tools

🚀 Explosive

Expected at 90%+ of product company teams in 2025. Knowing how to use Copilot effectively — not just accepting suggestions blindly — is now a baseline expectation.

"Comfortable working with AI-assisted coding tools such as GitHub Copilot or Cursor."
2

Spring AI

Java + AI

🚀 Explosive

Spring's official AI integration framework. Companies building Java products are adding AI features and reaching for Spring AI first. Huge demand at mid/senior level.

"Experience with Spring AI or LangChain4j to build LLM-powered backend services."
3

LangChain4j

Java + AI

📈 Rising

The Java-native LLM framework. RAG pipelines, AI agents, tool calling — all in familiar Java/Spring idioms. Growing fast in fintech and enterprise Java shops.

"Build RAG pipelines using LangChain4j or Spring AI with vector store integration."
4

RAG (Retrieval-Augmented Generation)

AI Architecture

📈 Rising

The pattern behind AI features that use your own data. Showing up in senior JDs across all industries — especially fintech, edtech, and enterprise SaaS.

"Design and build RAG-based document Q&A systems using pgvector or Pinecone."
5

Kubernetes (K8s)

DevOps / Cloud

✅ Steady

No longer optional at mid/senior level. Companies migrated to K8s 2–3 years ago and now expect engineers to operate, not just deploy to it.

"Hands-on with Kubernetes — deployments, services, HPA, config management."
6

Prompt Engineering

AI Dev Skills

📈 Rising

Writing effective prompts is now a developer skill — for code generation, spec writing, test generation, and documentation. Showing up explicitly in JDs.

"Strong prompt engineering skills to leverage LLMs in development and feature delivery."
7

Virtual Threads (Java 21)

Java

📈 Rising

Java 21 virtual threads are replacing reactive frameworks for I/O-heavy services. Companies on Spring Boot 3.2+ are already migrating. Strong differentiator at mid/senior level.

"Familiar with Java 21 features including virtual threads and structured concurrency."
8

Apache Kafka

Messaging

✅ Steady

The event backbone of every serious product company in India. No longer just for FAANG — Swiggy, Flipkart, Paytm, PhonePe — all use Kafka heavily.

"Strong understanding of Kafka — topics, partitions, consumer groups, offset management."
