Role Overview

As a Software Engineer, you will work on backend services and integrations that power real-world healthcare processes, collaborating closely with a cross-functional team of developers, QA, and business analysts.

We are looking for candidates who have experience with Java and .NET

Responsibilities

• Design, develop, test, and maintain backend services and APIs using Java (Spring / Spring Boot or equivalent frameworks).
• Contribute to the healthcare platform, including features related to patient/clinical data workflows, reporting, and system integrations.
• Write clean, well-tested, maintainable code and participate in code reviews.
• Work with relational databases (e.g., PostgreSQL, MS SQL, Oracle) for data modeling, queries, and performance tuning.
• Collaborate with QA, DevOps, and business analysts to deliver features that meet functional and non-functional requirements, including healthcare data security and compliance considerations.
• Where relevant, support or contribute to .NET-based components or integrations within the broader system landscape.
• Participate in Agile ceremonies (sprint planning, stand-ups, retrospectives) and contribute to continuous improvement of team practices.
• Troubleshoot and resolve production issues, including root-cause analysis and post-incident follow-up.

Requirements

• Solid hands-on experience with Java (Core Java, OOP principles); experience with Spring / Spring Boot is a strong advantage.
• Working knowledge of .NET (C#) is a plus — ability to read, understand, and work with .NET code/integrations when needed.
• Experience with relational databases and SQL.
• Familiarity with REST API design and integration patterns.
• Understanding of version control (Git) and collaborative development workflows.
• Good problem-solving skills and attention to detail, especially given the sensitivity of healthcare data.
• Good communication skills in English (written and spoken), sufficient for working with an international/cross-functional team.
