For over 100 years, bp has focused on discovering, developing, and producing oil and gas in the nations where we operate. We are one of the few companies globally that can provide governments and customers with an integrated energy offering. Delivering our strategy sustainably is fundamental to achieving our ambition to be a net zero company by 2050 or sooner! Job DescriptionSummary Were looking for engineers who think holistically, automate relentlessly, and are fluent in the fast-moving world of AI tooling and infrastructurebut grounded in disciplined engineering principles. Our AI organization is building high-impact AI-powered applications that deliver real business value at speed. As a Senior Software Engineer, youll play a critical role in building and deploying scalable AI-powered applications through solid software engineering excellence combined with pragmatic use of modern AI capabilities. This is a role for seasoned engineers who are excited about applying AI in practical and scalable ways. Were looking for individuals who thrive at the intersection of disciplined software development and modern AI applications. You should be comfortable working across the full lifecycle of a productfrom ideation and architecture to deployment and automationwhile navigating ambiguity and driving toward execution. Strong systems thinking, ownership mindset, and the ability to ship value fast are essential. Job ResponsibilitiesDesign, develop, and maintain production-grade AI applications and services using modern software engineering practices (CI/CD, testing, observability, cloud-native design). Define and implement foundational platforms and tools (e.g., conversational bots, AI-powered search, unstructured data processing, GenBI) that are reusable and scalable across the enterprise. Participate in cross functional team initiativesembedded projects with business stakeholdersto rapidly build and deploy AI solutions that solve high-priority business problems. Evaluate and integrate existing AI tools, frameworks, and APIs (e.g., LLMs, vector DBs, retrieval-augmented generation, AI agents) into robust applications. Champion automation in workflowsfrom data management ingestion and preprocessing to evaluation, to model integration and deployment. Collaborate with data scientists, product managers, and other engineers to ensure end-to-end delivery and reliability of AI products. Stay current with emerging AI technologies, but prioritize practical application and delivery over experimental research. Contribute to the internal knowledge base, tooling libraries, and documentation to scale AI engineering best practices across the organization.
