Vision for Tomorrow’s Opportunities.\nJoin William Blair, the Premier Global Partnership.\nWe are hiring a Senior AI Engineer to join a newly formed AI Innovation Function, part of the Investment Banking AI & Technology team. This is not a back-office engineering role. This role follows the Forward Deployed Engineer philosophy: you will not build in isolation. You will be embedded with deal teams and industry/sector groups, understanding their day-to-day workflows and delivering tools that create immediate, measurable impact on how they originate, execute, and close deals.\nYou will work across the full stack-data pipelines, ML models, LLM-powered applications, and Salesforce integrations-with a bias for shipping fast, learning from real user feedback, and iterating relentlessly.\nResponsibilities include but may not be limited to:\nBuild AI-powered features and agents using Enterprise Claude and proprietary ML models, integrated directly into the Salesforce workflows bankers use every day.\nDevelop LLM applications for banking use cases including automated comparable analysis, buyer recommendation, meeting intelligence summarization, and deal status briefings.\nDesign and maintain data pipelines using Databricks and Dagster for feature engineering, model training, and real-time analytics.\nWork directly with deal teams and industry groups to identify high-impact automation opportunities and translate banker pain points into working solutions.\nPerform rapid prototyping and exploratory analysis-build proof-of-concept tools quickly to validate ideas before investing in production-grade implementations.\nIntegrate third-party AI tools (Rogo.ai, Blueflame AI, Fellow.ai) via APIs and ensure seamless data flows across the composable architecture.\nWrite well-tested, production-quality code with rigorous engineering practices: code reviews, CI/CD, monitoring, and documentation.\nContribute to the team’s engineering standards and share knowledge as the team scales.\nQualifications:\n3+ years of software engineering experience with full-stack capability and a track record of shipping production applications.\nExperience building applications or agents using large language models: prompt engineering, RAG architectures, LLM orchestration, or tool-use patterns.\nExperience building interconnected multi-agent ecosystems - implementing agent coordination, shared tooling, and communication patterns across autonomous components.\nSolid ML fundamentals: ability to perform data analysis, build and evaluate models, and work with feature pipelines.\nRigorous engineering habits-you believe in tested code, clean architecture, and building for maintainability from the start.\nFamiliarity with capital markets; experience in or adjacent to investment banking, private equity, venture capital, or hedge funds is strongly preferred.\nExperience with cloud platforms (Azure preferred), data tools (Databricks, Spark), and pipeline orchestration (Dagster, Airflow, or similar).\nOutcome-focused mindset-you care about whether bankers actually use what you build and whether it moves the needle on their productivity.\nPreferred Qualifications:\nExperience in a Forward Deployed Engineer, solutions engineer, or embedded technical role with direct business stakeholder accountability.\nExperience deploying multi-agent ecosystems into production environments - including operational monitoring, failure handling, and end-to-end lifecycle management.\nExposure to financial services workflows: deal execution, pitch preparation, due diligence, or financial modeling.\nExperience working with Salesforce APIs or CRM platforms as integration surfaces.\nA builder’s mentality: you have side projects, open-source contributions, or a portfolio that demonstrates curiosity and initiative beyond your day job.\nA reasonable estimate of the current base salary range at time of posting is below. Base salary does not include other forms of compensation or benefits. Actual base salary within the specified range is based on several factors, including but not limited to applicant's skills, prior relevant experience, specific degrees and certifications, job responsibilities, market considerations and, if applicable, the location of the position.\nThis role is eligible for either a discretionary annual bonus (based on company, business unit and individual performance) and/or commission-based incentives.\nOur featured benefit offerings include medical, dental and vision coverage, employer paid short & long-term disability and life insurance, 401(k), profit sharing, paid time off, Maven family & fertility benefit, parental leave (including adoption, surrogacy, and foster placement), as well as other voluntary benefits. \nSalary Range\n$157,000—$187,000 USD\n\nAbout Our Firm\nWilliam Blair strives to attract qualified candidates who specialize in investment banking, investment management, private wealth management, and other strategic resource groups.
