Our client, a fast-growing organization developing secure, scalable technologies for next-generation AI applications, is seeking a Backend Engineer to join their core platform team.

In this role, you’ll help build and refine the foundational services that power authentication, observability, data flows, and high-availability systems across a distributed ecosystem. This is an opportunity to work on complex backend challenges while shaping the infrastructure that supports mission-critical applications.

• Develop, enhance, and support backend services that form the foundation of the platform.
• Build and maintain core authentication and authorization capabilities.
• Apply principles of Domain-Driven Design to guide how services and components evolve over time.
• Architect, extend, and support event-sourced systems to ensure durable, consistent operations at scale.
• Participate in API design and integration efforts across internal and external stakeholders.
• Implement and support messaging frameworks (e.g., NATS) to enable reliable service-to-service communication.
• Maintain and improve observability tooling—including metrics, tracing, and logging—to ensure healthy system performance.
• Work closely with infrastructure, Dev Ops, and engineering teams to ensure robust, secure, and maintainable operations.

• 3–6+ years of experience as a backend engineer.
• Strong knowledge of distributed systems and microservices.
• Proficiency in at least one modern backend programming language (C#, Go, Rust, etc.).
• Practical experience with IAM concepts and authentication/authorization frameworks.
• Exposure to event-sourcing patterns, DDD, and common messaging systems (e.g., NATS, Kafka, SNS, Rabbit
  
  MQ).
• Familiarity with Redis or similar in-memory caching technologies.
• Experience working with observability tools such as Prometheus, Jaeger, ELK, or Application Insights.
• Understanding of cloud-native environments and deployment workflows (AWS, Azure, or GCP).

You’ll contribute directly to a foundational platform used across an entire organization—impacting performance, reliability, and security at every layer. If you enjoy solving distributed-system challenges and working on complex, high-scale backend services, this is a strong match.
