Senior Backend Engineer

As a physician-founded and led organization, ensuring everyone has access to quality healthcare is what inspires us. The magic we’ve created lies in Carbon Health’s custom EHR and the collaboration among clinical teams, engineers, and designers who work side-by-side to deliver innovation like our hands free AI charting tool. That’s why we hire people who genuinely care about patients, solving healthcare challenges, and making a positive impact every day. Join us and help change the future of healthcare for the better.

About the role

We're looking for a Senior Backend Engineer who enjoys building reliable, scalable services that real clinical workflows depend on. You'll design and own backend systems, APIs, and the event-driven infrastructure that connects them.

This is a hands-on engineering role for someone who can take a service from technical design to production, make pragmatic decisions, and collaborate effectively with product and engineering teams.

You'll work with modern JVM technologies, AWS, and event-driven systems in a healthcare technology environment where reliability, data integrity, and delivery matter.

What you'll do

• Design, build, and own JVM backend services (Java, Kotlin, or Scala) from technical design through production.
• Build reliable service-to-service communication with gRPC: well-defined contracts, deadlines and timeouts, retries with backoff, idempotent operations, and graceful degradation when a dependency fails.
• Design public and internal APIs (REST, GraphQL)
• Build event-driven and asynchronous workflows that stay consistent under failure, using patterns such as idempotent consumers, dead-letter handling, Saga, and Transactional Outbox.
• Own the infrastructure your services run on: define and evolve it with Terraform, review infrastructure changes like application code, and ship through automated CI/CD pipelines.
• Make services observable with metrics, structured logging, distributed tracing, and alerting tied to service-level objectives.
• Model data and tune queries in relational databases so performance stays predictable as data grows.
• Handle sensitive healthcare data responsibly through access control, encryption, and audit trails.
• Write maintainable, well-tested code, lead technical design discussions, and help raise the bar through reviews and mentoring.
• 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 building and operating backend systems in production.
• Solid experience with the JVM ecosystem: Java, Kotlin, or Scala.
• Hands-on experience with gRPC or a similar RPC framework for service-to-service communication, including timeouts, retries, and failure handling.
• Experience designing production-grade APIs with REST and GraphQL.
• Experience with event-driven architecture and message queues, and with the delivery and consistency challenges that come with them.
• Solid relational database experience: schema design, indexing, and query performance.
• Hands-on experience managing cloud infrastructure (AWS preferred) with Terraform.
• Experience running services in production: observability, incident response, and root-cause analysis.
• 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 healthcare data standards such as HL7 or FHIR.
• Experience with resilience patterns such as circuit breakers, bulkheads, and rate limiting.
• Experience with stream processing or change data capture.
• Experience with containers and container orchestration.
• Some frontend familiarity to collaborate smoothly across the stack.
• Experience contributing to technical architecture and mentoring other engineers.

What we offer

• Remote-first, full-time, permanent employment in Türkiye.
• 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.
