Cognizant Hiring 2026 brings an opportunity for experienced Java Full Stack Developers with 6 to 10 years of experience. The opening is for a Java Full Stack Developer role mentioning Angular and AI, with job locations in Chennai, Bengaluru and Hyderabad.
Although the job title highlights Angular and AI, the detailed job description focuses primarily on Java, Spring Boot, Spring Batch, RESTful web services, AWS, CI/CD and database technologies such as Aurora or PostgreSQL.
If you are considering applying, it is important to understand what Cognizant actually expects from candidates. This guide covers the job requirements, technical skills, experience criteria, locations, interview preparation and application tips to help you assess this opportunity.
The listing in brief
- Company: Cognizant, IT services and consulting
- Role: Java Full Stack Developer, with Angular and AI in the post title
- Experience: 6 to 10 years on the header; the description says more than 6 years
- Level of hire: SA, which most likely stands for Senior Associate (the post does not spell it out)
- Locations: Hyderabad, Chennai and Bengaluru, on a hybrid basis
- Salary: not disclosed
- Openings: one, with more than 100 applicants two days after posting
- Education: any graduate
- Type: full time, permanent
What the headline says and what the body says
The title includes “Angular” and “AI”. The description never mentions either. Its primary skills are Java, Spring Boot, Spring Batch, RESTful web services, AWS and CI/CD, plus working knowledge of Aurora or Postgres. Its secondary skills are Kafka, monitoring tools such as Kibana and Datadog, and API gateway and load balancer knowledge. The “Key Skills” tags on the page confirm the same list and add nothing about front-end work.
That gap matters in two ways. First, you should not skip the application because you have no Angular or AI experience; the written requirements are backend and cloud heavy. Second, you should not assume the interview will stay there either. A title is often written by the hiring team and may reflect where the project is heading, so having a short, honest answer about Angular and about AI tools is a sensible precaution. Ask the recruiter which of the two is actually needed on the project.
The post also opens with the line “application development and enhancement, FSE”. That points to work on an existing product, adding features and fixing problems, rather than building a system from nothing.
The primary stack, in the order the post lists it
Java and Spring Boot. These are the foundation, and at six-plus years you are expected to know them well. Beyond the syntax, be ready to talk about how Spring Boot starts up, how beans are wired, how profiles and configuration work across environments, and how you handle errors and validation in a service.
Spring Batch. This is the item that separates this posting from a generic Java role, and it appears in the primary list and in the key skills tags. Spring Batch is the framework for jobs that process large volumes of records in chunks: reading from a source, transforming, and writing out. Know the vocabulary of job, step, reader, processor and writer, how chunk size affects memory and transaction boundaries, how restart and skip behaviour work after a failure, and how job metadata is stored. Many strong Spring Boot developers have never used it, so even a small project here sets you apart.
RESTful web services. Expect the usual: resource design, status codes, idempotency, versioning, pagination and error responses. The post lists API gateway and load balancer knowledge as secondary, which suggests the services sit behind managed infrastructure, so be able to explain what each of those layers does for you.
AWS. The post names AWS without listing services, so prepare the ones a Java backend most often touches: compute such as EC2, ECS or EKS, Lambda for event-driven pieces, S3 for files, IAM for permissions, and the managed database service. Aurora appears in the key skills, so be clear on how it relates to a standard Postgres or MySQL deployment.
CI/CD. Describe a pipeline you have worked with from commit to deployment: build, unit and integration tests, static analysis, packaging, deployment and rollback. The post does not name a tool, so speak about the one you know and the principles that carry across tools.
Aurora or Postgres. The post asks for working knowledge. That means writing and reading SQL comfortably, understanding indexes and query plans, transactions and isolation, and connection pooling from a Java service.
The secondary stack
The secondary skills are described as advantages, so treat them as tie-breakers in a crowded field.
- Kafka. Know topics, partitions, consumer groups, offsets and delivery guarantees, and why you would put an event stream between two services.
- Kibana and Datadog. These are about observability. Be ready to describe how you traced a slow request or a failing job using logs, metrics and dashboards.
- API gateway and load balancer. Understand routing, authentication at the edge, rate limiting, health checks and how traffic is spread across instances.
A weekend project that covers most of the post
With one opening and a large pool of candidates, concrete evidence helps. A small project can touch nearly every line of the description:
- Build a Spring Boot service that exposes a REST endpoint to upload or trigger a file of records.
- Add a Spring Batch job that reads the records in chunks, validates them and writes them to Postgres.
- Publish a Kafka event for each processed batch so another small service can react.
- Package it, set up a CI pipeline that builds and tests it, and deploy it to an AWS free-tier environment.
- Send logs to a dashboard and write down what you would alert on.
You do not need to finish all five steps to benefit. Even the first three give you something real to explain in an interview, and the answer to “tell me about a Spring Batch job you built” stops being theoretical.

Where Angular and AI might come in
The post gives no detail, so the following is a reasonable guess, not a fact. A full stack label with Angular preferred usually means some screens in Angular and TypeScript that call the services you build. The AI mention could mean a team that uses AI-assisted development tools, or a product with AI features that your services feed. In either case, a modest, truthful answer works: describe the Angular work you have done, or say you have used it lightly and can pick it up, and explain how you use AI tools to write or review code responsibly. Avoid claiming depth you do not have.
Interview questions to rehearse
- How does a chunk-oriented Spring Batch step handle a failure halfway through? Cover transaction per chunk, skip and retry policies, and restart from the last committed point using job metadata.
- How would you process ten million records nightly without running out of memory? Talk about chunk size, streaming readers, paging queries, partitioning the step and parallel processing.
- A REST endpoint is slow in production. What do you check first? Start with metrics and logs to find where time goes, then database queries and connection pool, then downstream calls.
- Why might you use Kafka between two services instead of a direct call? Decoupling, buffering bursts, replay, and the cost of added complexity and eventual consistency.
- What is the difference between a load balancer and an API gateway? One spreads traffic across instances; the other handles routing, authentication, throttling and request shaping.
- Walk me through a deployment that went wrong. Describe detection, rollback and what changed in the pipeline afterwards.
Applying: what to put in front of the recruiter
Lead your resume with Java, Spring Boot, Spring Batch, AWS and CI/CD, in that order, since the post does. Add a line each for Postgres or Aurora, Kafka and your monitoring tools. Put numbers on outcomes: records processed per run, runtime reduced, incidents avoided. State which of the three cities you prefer and your notice period, as the post does not specify one. Because the salary is not disclosed, arrive with a figure based on your experience and current package, and ask about the number of days expected in the office under the hybrid model.
