Job Description

DevOps Engineer

Role Overview

We are looking for a hands-on, responsible and growth-oriented DevOps Engineer with approximately 1–2 years of experience who is interested in building strong practical expertise in Linux, Docker, CI/CD, server management, deployment automation, security, monitoring and infrastructure management .

GwayERP and ThiranERP are growing rapidly, and we are preparing our infrastructure and deployment processes to support an increasing number of ERP implementations and frequent application releases.

The selected candidate will work closely with the development, QA and technical teams to maintain the existing environments, improve the current infrastructure, automate repetitive activities, strengthen security, improve documentation and progressively build a reliable deployment ecosystem.

This role is ideal for someone who has a good foundation in DevOps and is willing to learn deeply, take responsibility, research solutions independently and grow into larger infrastructure and DevOps responsibilities .

The candidate does not need to know everything from day one.

However, The Candidate Must Have The Mindset:

“If I don't know it, I will learn it, understand it properly, implement it safely and document it.”

Work with developers to improve the way GwayERP and ThiranERP applications are deployed.

The candidate will help establish a standardized deployment process such as:

Code → Build → Release → Deploy → Verify

Responsibilities Include:

Understanding application deployment requirements.

Preparing deployment scripts.

Automating repetitive deployment tasks.

Supporting application updates.

Maintaining deployment configurations.

Performing deployment verification.

Supporting rollback procedures.

Maintaining deployment documentation.

The candidate should continuously identify opportunities to eliminate unnecessary manual steps.

Preparing for High-Volume Deployments

GwayERP and ThiranERP are expected to be deployed to an increasing number of customers.

The candidate will work with technical team members and developers to understand this requirement and progressively improve the deployment architecture.

Responsibilities Include:

Identifying deployment bottlenecks.

Automating repetitive deployment tasks.

Improving deployment speed.

Improving deployment reliability.

Standardizing client deployment procedures.

Supporting parallel deployment where appropriate.

Maintaining deployment records.

Learning and implementing suitable DevOps practices for higher deployment volumes.

The candidate is expected to grow with the requirement and continuously improve the deployment system as the number of clients increases.

Secure Client Deployment

GwayERP And ThiranERP Applications May Be Deployed In:

Customer on-premises servers

Customer-preferred cloud servers

Other approved customer environments

The candidate will assist in developing a deployment architecture where the application can run securely in the customer's environment without unnecessarily exposing the organization's source code.

The candidate should learn and work with concepts such as:

Docker images

Private container registries

Build artifacts

Runtime configuration

Secrets management

Access control

Secure deployment packages

Application versioning

Container security

The Objective Is:

ERP Applications Will Continuously Receive:

Bug fixes

Security fixes

New features

Performance improvements

Workflow enhancements

The DevOps process must support updating existing client installations safely.
