• Develop and maintain the server-side logic of our applications using Java.
• Implement efficient and performant backend code for high-volume production applications.
• Monitor application health and reliability in the production environment.
• Contribute to all phases of the development lifecycle, from concept to deployment.
• Review and refactor code, establishing best practices for code hygiene and organization.
• Lead a team of developers while providing mentorship to less-experienced developers, fostering an environment of continuous learning and improvement.
• Identify and manage risks regarding project deadlines and technical solutions.

• Strong understanding of Agile process, roles within the process, and key ceremonies.

Optional requirements:

• Experience with API contract testing.
• NoSQL (e.g., MongoDB, Cassandra).
• Prompt engineering and experience with integration of GenAI LLMs into productions (ideally) or pet projects at least (OpenAI, Azure OpenAI, Bard, Llama)
• Familiarity with federated Graph architectures.
• Hands-on experience with Google Cloud Platform.
• ReactJS experience is a nice-to-have.

Personal attributes:

• Strong communication and team collaboration skills.
• Ability to learn quickly and adapt to new technologies.
