Digital AI / Agentic Software Engineer Job ID: 102335 Do you want to work on complex and pressing challenges-the kind that bring together curious, ambitious, and determined leaders who strive to become better every day? If this sounds like you, you've come to the right place. Your Impact You will work with our firm's top technical minds on a solution that will enable the next generation of client service. You'll be part of building a platform that will be deployed across regions, sectors and functions. Focusing on a distinctive combination of AI capabilities, domain expertise, and human judgement. You'll be at the forefront of developing exciting technology for our firm. As an AI / Agentic Software Engineer, you will design, build, and operate agentic systems that power GenAI applications. You'll use LangGraph and LangChain to author multi-step, tool-using agents with robust state management, planning, and recovery; define and evolve function/tool schemas; implement tool routing, parallelization, and fallbacks; integrate retrieval, memory, and context windows; add guardrails, evaluation harnesses, and tracing for safety and observability; and expose agents via APIs and workflows. You'll also integrate ETL-heavy procedural workflows through modern orchestrators (e.g., Airflow, Prefect, Dagster, AWS Step Functions), modeling long-running DAGs as tool-invocable tasks with retries, backfills, idempotency, SLAs, lineage, and data-quality checks-so agents can schedule, monitor, and adapt pipelines in response to real-time signals. You'll write production-grade Python/TypeScript with comprehensive tests, create and modify GitHub Actions CI/CD pipelines, and operate AWS- and Docker-based infrastructure with attention to reliability, latency, and cost.
