Description
We are seeking a highly motivated and experienced Senior AI Engineer to join and help lead an experienced team of software developers. You will take a senior, hands-on technical role in building a new, strategically important AI system that directly powers one of Citi's Global Lending Platforms. This is a great opportunity to build AI at real scale inside a leading global financial institution, shaping architecture and technical direction while mentoring engineers and partnering closely with senior stakeholders, in a culture that values craft, ownership, and continuous learning.
Responsibilities
- Design and implement software components and applications for AI systems, with a primary focus on data
- Build MCP (Model Context Protocol) tools and AI agents that effectively utilize this data to solve business problems
- Act as a senior, hands-on technical leader within a skilled SCRUM team — take ownership of complex, ambiguous problems, drive features from design through production, and ensure delivery of high-quality, production-grade applications
- Thrive in a fast-paced, results-driven execution environment, balancing speed with engineering excellence, and proactively identify and resolve technical risks before they impact delivery
- Lead code reviews, drive technical discussions, and help define shared engineering standards; mentor and coach junior and mid-level engineers to raise the overall capability of the team
- Partner with product owners, architects, and senior stakeholders to translate business requirements into scalable, resilient technical solutions
- Exercise sound judgment on architecture, design trade-offs, and technology choices, balancing short-term delivery needs with long-term platform health
- Champion engineering rigor across the team, including testing, observability, security, and operational readiness for production AI systems
Skills & Qualifications
- Significant experience as a Software Engineer, with a track record of increasing scope, ownership, and technical leadership
- Experience working in complex enterprise environments, collaborating with global teams
- Experience applying large language models (LLMs) to solve real business problems, from ideation through to production deployment
- Deep fluency in the Python AI/ML ecosystem, including Pydantic, REST API integration, database access, and orchestration frameworks such as ADK or LangGraph
- Strong proficiency in SQL and working with complex data in enterprise environments
- Demonstrated experience leading or mentoring engineers, influencing technical direction, and driving engineering standards within a team – big plus
- A genuine team player who can also operate with full autonomy and ownership — equally effective in the office or working remotely
- Sharp, structured thinker with strong analytical skills, sound judgment, and the ability to independently research, evaluate, and master new technical domains
- Excellent interpersonal, communication, and stakeholder-management skills in English
- Bachelor's degree in Computer Science or related field; advanced degree a plus
What's in It for You
- Take on a senior, high-visibility role working alongside experienced engineers while helping shape the growth of others
- Work on a complex, high-stakes project deployed globally within a leading financial institution
- Operate in a culture that actively encourages and sponsors personal and professional development
- Build with cutting-edge AI tools — MCP, LLMs, agent frameworks — at real enterprise scale, with the latitude to influence architecture and technical direction
- Flexible hybrid working model supporting both office collaboration and remote productivity
