Remote C# Engineer

SBS is seeking a skilled AI Engineer to join its Data & AI / Engineering organization in the UK or EU. This role will focus on designing, building, and deploying AI-driven solutions that enhance SBS products and client offerings. The ideal candidate will combine strong software engineering fundamentals with applied AI/ML expertise, enabling the development of scalable, production-grade AI systems in a regulated financial services environment.

Location: UK or EU

Hybrid/Remote: Remote (Occasional travel required)

Responsibilities:

• AI Solution Development: Design, build, and deploy AI/ML models and intelligent applications across SBS platforms. Develop solutions leveraging Machine Learning (ML), Natural Language Processing (NLP), and Generative AI (GenAI / LLMs). Translate business requirements into technical AI solutions that deliver measurable impact.
• Model Deployment & MLOps: Implement and manage end-to-end ML pipelines, from data ingestion to model deployment and monitoring. Collaborate with DevOps and engineering teams to ensure scalable, reliable production deployment. Maintain and optimize model performance, accuracy, and efficiency over time.
• Product Integration: Integrate AI capabilities into core banking, payments, and digital platforms. Work closely with Product Managers, Architects, and Developers to embed AI into customer-facing solutions. Support API development and microservices architecture for AI-driven features.
• Data Engineering Collaboration: Partner with data engineers to ensure data quality, availability, and pipeline integrity. Work with structured and unstructured datasets across large-scale, distributed systems.
• Innovation & Continuous Improvement: Stay current with advancements in AI, GenAI, and emerging technologies. Contribute to experimentation, prototyping, and innovation initiatives. Identify opportunities to improve automation, efficiency, and decision-making through AI.

Qualifications:

• Software Architecture & Design: Strong grasp of clean/hexagonal architecture, dependency injection, SOLID principles, and protocol-based interfaces. Can design well-structured Python services with clear separation of concerns, testable components, and maintainable codebases.
• API design: Experience designing and maintaining RESTful API contracts. Understands OpenAPI specifications, versioning strategies, schema evolution, and backward compatibility.
• System design: Distributed systems thinking — understands event-driven patterns, asynchronous communication, eventual consistency, and the trade-offs of different integration approaches.
• Data modeling: Can design domain models, define data flows between system components, and make pragmatic schema design decisions.
• AI & LLM Application Skills: Hands-on experience building production applications powered by LLMs. Must go beyond API calls — RAG pipelines, chain-of-thought reasoning, structured output parsing, multi-step workflows.
• Model-agnostic design: The candidate must design against standardized API interfaces (OpenAI-compatible, LiteLLM, or equivalent abstraction layers).
• Agentic system design: Demonstrated experience designing multi-step AI systems where the model makes decisions about what to do next.
• Prompt engineering depth: Can demonstrate iterative prompt development for complex tasks.
• Python Engineering: Strong async Python with FastAPI or equivalent framework. Comfortable with Pydantic for data validation, SQLAlchemy for data access, and structured logging.
• Engineering Qualities: The candidate joins a substantial existing codebase and architecture. They must be comfortable reading, understanding, and extending code they did not write.
