We're looking for a Senior Software Engineer to contribute to the development of Graal Cloud Service, a platform bringing high-performance, polyglot runtime capabilities to cloud-native environments.

This is an opportunity to work at the intersection of runtime technologies, cloud infrastructure and developer platforms, helping applications achieve faster startup times, lower memory consumption and improved performance at scale.

In this role, you'll design, develop and optimise components of cloud-native runtime systems using GraalVM, native image compilation and modern cloud technologies.

You'll work alongside experienced engineers, contribute to technical design discussions and help deliver reliable, scalable and secure solutions.

Responsibilities
What You'll Do

- Design, develop and maintain cloud-native runtime components leveraging GraalVM and native image technologies, including integration with Oracle Database.

- Build and enhance solutions supporting low-latency execution, serverless runtimes and multi-tenant environments.

- Contribute to the development and integration of runtime capabilities supporting applications and workloads.

- Analyse and optimise application startup time, memory utilisation and throughput in distributed systems.

- Implement performance improvements using profiling, benchmarking and diagnostic tools.

- Develop, test, debug and maintain high-quality software components following established engineering practices.

- Collaborate with infrastructure, database and application engineering teams to develop and integrate runtime capabilities.

- Participate in technical design discussions, contribute engineering recommendations and help improve existing architectures.

- Support the development of scalable, reliable, observable and secure cloud services.

- Investigate complex technical issues, identify root causes and implement effective solutions.

- Contribute to code reviews, technical documentation, knowledge sharing and continuous improvement initiatives.

- Explore opportunities to apply automation and data-driven approaches to improve platform efficiency and developer experience.

What You'll Bring

- Bachelor's or Master's degree in Computer Science, Software Engineering or a related technical field, or equivalent practical experience.

- Typically 5+ years of professional software development experience, ideally involving systems engineering, runtime technologies or cloud infrastructure.

- Strong programming skills in Java, with experience developing, debugging and maintaining production-quality software.

- Good understanding of JVM internals, compilers or runtime systems , such as GraalVM, HotSpot or LLVM.

- Experience with distributed systems and cloud-native architectures, including technologies such as Kubernetes, microservices or serverless computing.

- Practical experience with performance optimisation, profiling, debugging and system troubleshooting.

- Understanding of software design principles, algorithms, data structures and concurrent programming.

- Experience developing and maintaining reliable, scalable software services.

- Ability to investigate complex technical problems and implement effective engineering solutions.

- Strong collaboration and communication skills, with the ability to contribute effectively within a technical team.

- Willingness to learn new technologies, share knowledge and continuously improve engineering practices.

What We Offer

- Join a collaborative team where innovation, knowledge sharing and teamwork are valued.
