Tasks

• Design, build, and maintain backend services and REST APIs powering AI-enabled solutions: clean interfaces, robust domain models, and maintainable data access patterns.
• Deliver cloud-native microservices using Docker and Kubernetes, with attention to scalability, resilience, and cost.
• Build and maintain CI/CD pipelines with automated tests, quality gates, and secure delivery practices.
• Integrate and standardize API exposure via gateway patterns, including usage policies, throttling, authentication/authorization, and versioning (Azure API Management where applicable).
• Establish and maintain observability standards using Azure Monitor and Application Insights (dashboards, alerting, distributed tracing, and runbooks).
• Diagnose and resolve complex issues across microservices, clusters, and pipelines; perform root-cause analysis and preventative improvements.
• Embed security and resilience: secrets management, least privilege, container security best practices, and disaster recovery patterns.
• Engineer for regulated environments: implement audit-friendly practices such as traceable changes, reliable logging, and disciplined handling of sensitive data (minimization, access controls, retention).
• Collaborate with ML Engineers, Platform Engineers, AI Architects, and DevOps to deliver shared foundations and consistent standards across global teams.

Profile

• 5+ years professional backend engineering experience; MLOps or AI platform experience is a strong plus.
• Expert-level Python; ideally FastAPI, Pydantic, SQLAlchemy (or equivalent frameworks).
• Strong engineering fundamentals: testing strategies, REST API versioning, documentation, code quality, and pragmatic system design.
• Production experience with Docker and Kubernetes.
• Strong CI/CD experience (GitHub Actions preferred; ArgoCD or similar also relevant).
• Familiarity with Azure cloud platforms and services, particularly AKS, ACR, Key Vault, Azure Monitor/Application Insights, and Azure API Management (APIM).
• Strong experience with PostgreSQL including schema design, migrations, and performance tuning fundamentals.
• Familiarity with distributed systems and event-driven architectures using Kafka.
• Strong troubleshooting skills and an operational mindset.
