Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Engineer/Engineering Lead - Senior Vice President - **Company:** Citigroup Inc. - **Location:** London, UK (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Software Quality, Code Review, Continuous Integration, Data Mining, Python (Programming Language), PostgreSQL, Machine Translation, OpenShift, Oracle (Applications), Software Technical Review, Generative AI, AI Platforms, Kubernetes, Information Technology, Production Code, Machine Learning Operations, Virtual Agents, Functional Programming, Jenkins - **Published:** August 22, 2026 - **Apply:** https://dejobs.org/x/x/5032C0A02B0F481C95060067B775A406/job/ ## About the Role * Significant experience as a senior developer, technical lead, or similar role. Working alongside other teams to ensure that solutions work seamlessly across business verticals * Extensive experience crafting prompts across a variety of Generative AI models - you have strong, well-formed opinions on prompt structure and clarity, approaching it with the same rigor as The Elements of Style brings to writing. * Creative mindset -the problems we're solving often require novel solutions but are constrained by regulatory and compliance requirements. * Experience building production systems for one or more of: document/data extraction, NLP-based classification, machine translation, fraud or anomaly detection, or workflow automation. * Experience evaluating the performance of Generative AI applications - exposure to Mlflow, experiment design, evaluation methodologies. * Strong background in functional programming, technical design, and architecture. * Proficiency in Python- with hands-on experience. Exposure to Postgres/Oracle and Kubernetes (Openshift) is valuable. * Practical experience with CI/CD tooling (e.g. Jenkins, uDeploy, Tekton, Harness, or equivalent). * Exposure to Agentic AI, specifically ADK. * Strong problem-solving skills, attention to detail, and the ability to troubleshoot distributed problems. * Excellent communication and collaboration skills, with the willingness to engage at all levels. * Ability to adapt quickly in a dynamic environment where priorities evolve. Education * Bachelor's degree in computer science, science and engineering, or a related field. * Graduate-level or continuing education in a relevant discipline is a plus. ## Description This is a senior role within a deliberately flat team structure. You will be expected to take ownership, bring fresh thinking, and collaborate closely with colleagues across disciplines to deliver outcomes that genuinely make a difference. You will write bulletproof, production-grade code - not prototypes - to solve novel problems that sit at the frontier of applied Generative AI. Typical problem spaces you'll work on include intelligent data extraction from unstructured and semi-structured documents, content classification and routing, cross-language translation, fraud and document-tampering detection, and workflow optimisation across business processes. You'll be trusted to turn ambiguous, often first-of-a-kind problems into dependable services that the business can run its operations on. Because these solutions operate in a regulated banking environment, resilience, explainability, and auditability are as important as raw model performance - and you will move fluidly between experimentation, evaluating models, prompts, and architectures, and hardening the winning approach into dependable, scalable production code. You will gain meaningful exposure to AI development and solutions, alongside a broad range of technical work in a fast-moving, delivery-focused environment. Responsibilities * Own the design and build of high-quality, reliable software that scales. * Own, lead, and manage technical components end-to-end, ensuring alignment with business objectives and the wider product strategy. * Work with partners in Risk and other AI platform teams to help evolve Citi technology and procedures. * Partner with senior stakeholders to shape a compelling vision and technical roadmap for our products. * Provide technical guidance and mentorship to junior team members, elevating the team's overall capability. * Ensure software quality through rigorous code reviews, technical design reviews, and a strong testing culture. ## Related Videos - [Coffee with Developers - Maria Apazoglou](https://www.wearedevelopers.com/videos/1209-coffee-with-developers-maria-apazoglou) - [Optimizing Discovery: PostgreSQL's Role in Transforming GetYourGuide's Search](https://www.wearedevelopers.com/videos/1647-optimizing-discovery-postgresql-s-role-in-transforming-getyourguide-s-search) - [This Is Not Your Father's .NET](https://www.wearedevelopers.com/videos/967-this-is-not-your-father-s-net) - [The Road to MLOps: How Verivox Transitioned to AWS](https://www.wearedevelopers.com/videos/1050-the-road-to-mlops-how-verivox-transitioned-to-aws) - [The Future of Developer Experience with GenAI: Driving Engineering Excellence](https://www.wearedevelopers.com/videos/1107-the-future-of-developer-experience-with-genai-driving-engineering-excellence) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [The Prompt Engineer ✍️](https://www.wearedevelopers.com/magazine/216-the-prompt-engineer) - [Coffee with Developers - Maria Apazoglou - Making AI understandable for all in production](https://www.wearedevelopers.com/magazine/475-coffee-with-developers-maria-apazoglou-making-ai-understandable-for-all-in-production) - [Prompt Engineering is a Job of the Past](https://www.wearedevelopers.com/magazine/342-prompt-engineering-is-a-job-of-the-past) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Got AI ideas but no money?
