We prioritise efficiency, performance, observability, and high‑quality support while handling millions of requests, making integration with Docplanner smooth, reliable, and impactful.

We build APIs and services that handle millions of requests every day, ensuring doctors, patients, and partners can interact seamlessly across platforms. Our work enables innovations like AI‑powered doctor services to improve their efficiency as well as integrating with third‑party health care systems. We value innovation, scalability, and reliability, but above all, we care about creating technology that makes a real impact on people’s lives.

• Collaborate with product managers, designers, and stakeholders to deliver well‑designed, maintainable solutions.
• Promote agile practices, CI / CD, and DevOps culture within the team.
• Contribute to code reviews, automated testing, and comprehensive documentation.
• Support integration partners with reliable tooling and strong developer experience.
• Explore and integrate emerging technologies, including AI / ML, where relevant to backend systems.

Qualifications

• A senior backend engineer with deep expertise in designing and building highly scalable, reliable, and observable systems.
• Comfortable working across multiple modern programming languages.
• Curious, collaborative, and thrive in cross‑functional teams.
• Passionate about creating backend architectures that perform under high load, recover gracefully from failures, and provide clear insights through observability.
• Committed to clean, testable, and well‑documented code that supports long‑term maintainability.
• Excited to tackle complex technical challenges at scale and make strategic system design decisions that enhance overall reliability and performance.

What Will Help You Thrive?

• 8+ years of experience designing and building scalable backend systems.
• Strong expertise in designing distributed systems, async programming, and service‑oriented architectures.
• Hands‑on experience with message brokers, queues, or event‑driven systems (e.g., RabbitMQ, Kafka).
• Solid knowledge of database design and optimisation (SQL + NoSQL).
• Familiarity with cloud‑native practices, containerisation (Docker), and orchestration (Kubernetes).
• Strong grasp of software engineering best practices (SOLID, DRY, testing, CI / CD).
• Proficiency in English (B2+) for effective collaboration.
