Requirements

What we're looking for

What will make you successful in this position?

✅ A solid track record with Apache Tomcat

Your proven experience in Tomcat migrations and upgrades will allow you to quickly identify risks, dependencies, and critical points of a migration toward Tomcat 11.

✅ Experience in Middleware architecture

Your global vision of infrastructure, applications, and communications will be key to analyzing load balancers, reverse proxy, DNS, firewall, networking, clustering, and session management.

✅ Mastery of configuration and troubleshooting

Your experience with server.xml, context.xml, connectors, JVM, logs, SSL/TLS, and monitoring will allow you to get to the root of problems and technically validate each scenario.

✅ Knowledge of SQL DBs

Your experience with SQL Server and SQL databases will help you understand the dependencies between middleware, applications, and databases and anticipate possible impacts during the migration.

✅ Experience with Jakarta EE and Tomcat 11

Your knowledge of the implications of the Jakarta EE ecosystem will allow you to anticipate incompatibilities and distinguish infrastructure problems from those that should be referred to the partner responsible for the code.

✅ Auditor mindset and consultative capacity

Your success will depend as much on your technical knowledge as on your ability to ask the right questions, detect risks, and convey your conclusions clearly to the client.

✅ Autonomy in complex environments

You will have space to apply your professional judgment, work independently, and provide solutions, maintaining close communication with the client and the teams involved.

Do you feel like putting your Tomcat experience at the service of a high-level technical challenge?

If Apache Tomcat is one of your areas of expertise and you enjoy diving into complex architectures to understand them, detect risks, and make them evolve, this project may be a fit for you.

Take the next step and tell us how you would contribute your experience to this migration.

The role

Would you like to put your Apache Tomcat experience at the service of a critical project, acting as a technical reference in a migration to Tomcat 11? You will have autonomy, remote work, and a consulting project where your technical judgment will make the difference.

For approximately 4-6 months, you will accompany the client in the audit and validation of their middleware infrastructure, working with technologies such as Tomcat, Linux, SQL Server, JVM, Jakarta EE, networking, and security.

What will you find in this project?

✅ Autonomy and consultative vision

You will be the expert reference to analyze the existing architecture, detect risks, and provide an independent technical second opinion.

✅ A technically challenging feat

You will participate in a migration to Apache Tomcat 11, working on configuration, compatibility, infrastructure, security, performance, and Jakarta EE.

✅ Real impact in a critical environment

Your experience will help guarantee the stability, security, and evolution of a technological infrastructure key to the client's business.

Your mission

Your mission will be to provide an expert and independent vision regarding the client's middleware infrastructure, helping to validate that the migration to Apache Tomcat 11 is carried out with technical guarantees.

You will analyze architecture, configuration, security, performance, compatibility, and infrastructure to anticipate risks and turn your experience into technical decisions that provide stability and evolutionary capacity.

What you'll do

You will audit the current configuration and infrastructure and perform a technical analysis before and after the migration to Apache Tomcat 11.
You will accompany the migration process by providing your expertise, validating decisions, and detecting possible risks or incompatibilities.
You will propose improvements to the existing architecture and configuration and, when necessary, participate in their implementation.

How you'll work

✅ 100% remote work

The client is located in Madrid, but you will be able to develop the project remotely, maintaining the necessary coordination with the teams involved.

✅ Flexible schedule

You will be able to organize your workday with flexibility, ensuring availability for the necessary meetings and coordination moments with the client.

✅ Project of approximately 4-6 months

The initial planned duration is between 4 and 6 months, depending on the complexity of the audit and the evolution of the project.
