Mô tả công việc

We're looking for a Senior Backend Engineer to design and build reliable, scalable backend systems that power our internal platforms and business operations. You'll own systems end to end - from architecture and implementation through deployment, observability and production troubleshooting.

As we expand into AI, you'll also build and integrate LLM-powered capabilities and AI agent workflows into real internal processes.

What You'll Do: 
• Design and build backend systems: Own the architecture and development of scalable, reliable backend services and APIs.
• Solve distributed-system challenges: Design for idempotency, concurrency, consistency, retries, failure handling, and asynchronous or event-driven workflows.
• Build production-ready AI systems: Integrate LLM APIs or self-hosted models into backend services, and design the supporting systems for reliability, scalability, observability and maintainability.
• Build AI agent workflows: Tool calling, multi-step workflows, orchestration, and reliable AI-powered automation.
• Ensure performance and reliability: Optimize databases and queries, build observability through logging, metrics and tracing, and troubleshoot production issues.
• Drive engineering practices: Make architecture decisions, improve code quality, run code reviews, and mentor other engineers.

Yêu cầu

• Bachelor's degree in Computer Science, Software Engineering, Information Technology or a related technical field.
• 4 - 5 years of experience as a Backend Engineer, with strong ownership of production systems.
• Strong experience with at least one backend language such as Go, Python, Java or Node.js.
• Strong understanding of system design, API design and backend architecture.
• Experience with PostgreSQL, MySQL, MongoDB or similar databases, including performance tuning, indexing and transaction handling.
• Experience with message queues or event-driven architecture such as Kafka, RabbitMQ, Pub/Sub or SQS.
• Good understanding of distributed systems, including idempotency, concurrency, consistency, retries and failure handling.
• Experience with observability - logging, metrics and tracing.
• Experience diagnosing and troubleshooting production issues in large-scale or business-critical systems.
• Strong understanding of SOLID principles and Clean Architecture.
• Strong problem-solving skills, and the ability to independently research and evaluate new technologies and approaches.

Nice to Have: 
AI / LLM
• Hands-on experience with LLM applications, RAG, AI agents, tool calling or workflow orchestration.
• Experience integrating OpenAI, Claude or other LLM providers, or working with self-hosted open-source models.
• Experience building production-grade AI systems with a focus on reliability, evaluation, observability and scalability.
Platform & delivery
• Experience with Kubernetes or cloud-native technologies.
• Experience with AWS, GCP or similar cloud platforms.
• Experience building internal tools or workflow/AI platforms.
