At IBM Software, we transform client challenges into solutions. Building the world’s leading AI-powered, cloud-native products that shape the future of business and society. Our legacy of innovation creates endless opportunities for IBMers to learn, grow, and make an impact on a global scale. Working in Software means joining a team fueled by curiosity and collaboration. You’ll work with diverse technologies, partners, and industries to design, develop, and deliver solutions that power digital transformation. With a culture that values innovation, growth, and continuous learning, IBM Software places you at the heart of IBM’s product and technology landscape. Here, you’ll have the tools and opportunities to advance your career while creating software that changes the world.

Your role and responsibilities
  • Design, build, and operate production-grade Python backend services using FastAPI, Pydantic, and Uvicorn (ASGI architecture) with a focus on low-latency, high-reliability systems.
  • Own services end-to-end in production, including architecture design, implementation, testing with pytest, deployment, monitoring, and incident response.
  • Design API contracts and service boundaries for distributed systems, ensuring clear data flow, backward compatibility, and scalable integration patterns.

  • Build and operate LLM and agent-based production systems, integrating frameworks such as LangChain/LangGraph and model providers (e.g., AWS Bedrock, LiteLLM) into real workflows.
  • Distinguish and maintain separation between experimentation and production AI systems, ensuring safe rollout of model-driven features.
  • Design and evolve CI/CD pipelines that enforce automated testing, security validation, and deterministic, rollback-safe deployments.
  • Debug and resolve production incidents in distributed systems using logs, metrics, and distributed tracing (OpenTelemetry / ddtrace patterns), with clear ownership of service health.
  • Operate cloud-native services on AWS, including secure configuration, secrets management, IAM-controlled access, and production runtime reliability.
  • Design and maintain containerized workloads using Docker and Kubernetes, including rollout strategies (blue/green or rolling), health checks, autoscaling, and resource tuning.
  • Build systems with observability standards (metrics, tracing, logging) to ensure measurable reliability, performance, and failure diagnosis.
  • Participate in on-call or production support rotation with ownership for service-level outcomes and incident resolution.
  • Collaborate in Agile teams to translate stakeholder requirements into production systems, with emphasis on technical design ownership and delivery accountability.

  • Experience implementing security best practices in production, including least-privilege access, secrets rotation, and secure service-to-service communication.

ABOUT BUSINESS UNIT

IBM Software infuses core business operations with intelligence—from machine learning to generative AI—to help make organizations more responsive, productive, and resilient. IBM Software helps clients put AI into action now to create real value with trust, speed, and confidence across digital labor, IT automation, application modernization, security, and sustainability. Critical to this is the ability to make use of all data, because AI is only as good as the data that fuels it. In most organizations data is spread across multiple clouds, on premises, in private datacenters, and at the edge. IBM’s AI and data platform scales and accelerates the impact of AI with trusted data, and provides leading capabilities to train, tune and deploy AI across business. IBM’s hybrid cloud platform is one of the most comprehensive and consistent approach to development, security, and operations across hybrid environments—a flexible foundation for leveraging data, wherever it resides, to extend AI deep into a business.
