Job Description Summary
The Opportunity

The electricity grid is changing fast - and the software that runs it needs to keep pace. At GE Vernova's Electrification Software Global Delivery Center in Bucharest, you'll work on the systems that keep energy markets running: trading, settlement, balancing, capacity auctions, and more.

These aren't proof-of-concept projects. They're large-scale, distributed platforms used across multiple countries to manage real energy flows in real time.
If you're someone who finds deep technical problems genuinely interesting - and who wants to see your work matter at a systems level - this role was designed with you in mind.

Job Description

What You'll Do

You'll join an R&D team in the Market Management System (MMS) department, building a modern, modular platform for electricity market operations. You'll own your work end-to-end - from architecture decisions to deployment - and contribute to a team that values craft, collaboration, and continuous improvement.

• Design, build, and maintain high-quality Java code on a product used in live electricity markets across multiple regions.

• Take end-to-end ownership of the software lifecycle: solution design, architecture, coding, testing, deployment, and ongoing support.

• Optimize distributed systems for performance - working across transactions, caching, message queues, REST endpoints, and JVM profiling.

• Collaborate directly with business and domain experts to translate complex market rules and regulatory requirements into reliable, scalable software.

• Contribute to team standards in code quality, CI/CD, and software design - and actively share what you know.

• Troubleshoot and resolve issues across the full stack, including database query performance, concurrency, and integration points.

Who You Are

You're a seasoned Java engineer who thrives when the problems are hard and the stakes are high. You bring solid hands-on experience with enterprise systems, a sharp eye for performance, and the communication skills to explain complex solutions to both technical and non-technical audiences. You're comfortable owning your work and just as comfortable learning from the people around you.

Required

• Solid hands-on experience with Java 17+ and the Spring Boot ecosystem - including dependency injection, transactions, multithreading, concurrency, and aspect-oriented programming

• Strong proficiency in Hibernate / JPA: transactional behavior, query optimization, persistence best practices, and L1/L2 caching

• REST API development: design, error handling, and integration with front-end or third-party services

• Web security fundamentals, including OWASP principles and secure authentication/authorization flows

• Database proficiency across relational databases (Oracle, PostgreSQL, MS SQL), including query tuning and transactional integrity

• JVM and database query profiling and performance optimization

• Strong written and spoken English communication skills - you're able to explain complex technical solutions clearly.

Preferred

• Experience with distributed applications, messaging (JMS/MQ), workflow engines (Flowable/BPMN)

• DevOps/CI-CD tooling: Jenkins, Docker, Kubernetes, Argo CD, Helm

• Front-end exposure: Angular, TypeScript

• Scripting: Bash, Batch, Groovy.

Education

A formal education and subsequent Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field is nice to have, but we are most interested in your total experience and professional achievements.

What We Offer

GE Vernova employees rise to the challenge of building a world that works. To support that, we offer benefits designed to reward strong performance and help you manage your personal and family needs.

• Hybrid working model with flexible hours

• Private Medical Insurance (extendable to family members)

• Annual performance-based salary review and annual bonus

• Increasing vacation entitlement based on your work experience

• Full access to GE Vernova's learning platform, including Udemy and KodeKloud subscriptions

• Wellbeing programme including health-focused events, free wellness apps, and a confidential employee assistance programme

• Bookster subscription, corporate fitness discounts, meal vouchers, gift vouchers (Christmas and Easter), additional days off, and family benefits including children's events and gifts

We invest in your development with training programmes throughout the year and ongoing opportunities to grow your career through hands-on learning and structured support.
