Job description

We're looking for a Senior Software Engineer who enjoys working across the stack and building reliable, scalable products. You'll work on backend services, frontend applications, and the infrastructure that connects them.
This is a hands-on engineering role for someone who can take a feature from technical design to production, make pragmatic decisions, and collaborate effectively with product and engineering teams.
You'll be working with modern JVM technologies, React, React Native, AWS, and event-driven systems in a healthcare technology environment where reliability and delivery matter.

What you'll do

• Design, develop, and maintain backend services using Java, Kotlin, or Scala.
• Build and evolve APIs using REST, gRPC, and GraphQL, including Apollo-based integrations.
• Develop frontend applications with React, Next.js, and React Native (Expo).
• Design and implement real-time communication features using WebSockets, event queues, and message brokers.
• Work with AWS services and contribute to cloud infrastructure and deployment practices.
• Use Terraform and other infrastructure-as-code tools for basic infrastructure provisioning and management.
• Improve application observability using tools such as Grafana and Prometheus.
• Write maintainable, well-tested code and contribute to technical design discussions.
• Use AI effectively to improve development workflows, from exploration and implementation to testing, debugging, and documentation.
• Collaborate with product, design, and engineering teams to deliver features on time.

Qualifications

• Strong professional experience as a full-stack software engineer.
• Solid backend experience with the JVM ecosystem — Java, Kotlin, or Scala.
• Experience designing and building production-grade APIs with REST, gRPC, and GraphQL.
• Strong frontend experience with React and Next.js.
• Experience with React Native, preferably Expo.
• Experience working with AWS in production environments.
• Basic experience with Terraform or infrastructure-as-code practices.
• Experience with real-time systems, event-driven architecture, or message brokers such as SNS/SQS.
• Familiarity with application monitoring and observability tools such as Grafana and Prometheus.
• Strong problem-solving skills and a pragmatic approach to engineering decisions.
• Ability to work independently, communicate clearly, and take ownership of deliverables.
• Professional working proficiency in English, both written and verbal.
• A strong interest in using AI efficiently and responsibly in software development.
  Nice to have
• Experience in healthcare technology or other highly regulated industries.
• Experience with distributed systems and asynchronous processing.
• Experience with CI/CD, containers, and cloud-native deployment practices.
• Experience contributing to technical architecture and mentoring other engineers.

Qualifications

• Salary paid in USD, net.
• Payroll employment with the benefits of a permanent position.
• Access to our office at ODTÜ Teknokent, Ankara, with regular visits according to planned schedules.
• 100% private health insurance coverage for the employee.
• 50% private health insurance coverage for eligible family members, if you choose to include them.
• Floating vacation days: when a public holiday falls on a weekend, you can take the corresponding day off on a weekday of your choice, subject to applicable policies.
• The opportunity to work on meaningful healthcare technology products with a collaborative engineering team.
• A culture that values ownership, continuous learning, and delivering high-quality software.
