Citi is looking for a Principal Engineer to join its Payments Technology team, where you will drive the technical vision and hands-on engineering behind one of the most strategically important payment platforms in global financial services. This is an end-to-end technical leadership role — spanning core APIs, microservices architecture, integrations, and the infrastructure that underpins a comprehensive suite of payment capabilities for Citi's clients worldwide. If you combine deep engineering craft with the instinct to solve complex design problems and the conviction to raise standards across a team, this is the role for you.
Responsibilities
Architect and deliver end-to-end technical solutions across the payments platform, from core client-facing APIs through to integrations and supporting infrastructure.
Set and enforce engineering standards across the team — championing clean code, SOLID principles, and disciplined design practices that reduce technical debt and improve long-term maintainability.
Lead design reviews, proof-of-concept initiatives, and technical experiments that evaluate new approaches and establish the best path forward for platform evolution.
Translate complex system requirements into clear, well-structured software design artifacts that guide consistent, high-quality implementation across engineering teams.
Guide and mentor engineers at all levels on what good code and good design look like in practice, through hands-on collaboration, pairing, and direct technical coaching.
Coordinate technical delivery across internal and cross-functional teams, owning estimation, solution planning, and implementation leadership for concurrent initiatives.
Embed resilience and high-availability thinking into every layer of the architecture, ensuring platform reliability at the scale Citi's clients demand.
Manage technical risk with transparency and pragmatism, identifying issues early and communicating clearly to protect delivery timelines and platform integrity.

10 or more years of hands-on design and development experience, with deep Java expertise and a demonstrable commitment to clean code and SOLID engineering principles.
Practical experience building medium to large-scale applications using Spring Boot, Microservices, and Kafka on open-source technology stacks.
Hands-on experience with MongoDB and a strong grasp of data modelling and persistence patterns within distributed systems.
Proven ability to design and build resilient, high-availability architectures that perform reliably under real-world, high-throughput conditions.
Experience building and maintaining CI/CD pipelines and single-click deployment workflows, with familiarity across tooling such as Tekton, Harness, Lightspeed, or OpenShift.
Fluency in test-driven and behaviour-driven development practices, including writing unit and integration tests using JUnit and standard testing frameworks.
An active practitioner of AI tools and generative AI technologies, applying them to drive engineering productivity and delivery efficiency.
Clear, confident communicator who can articulate technical decisions and surface delivery risks effectively to both engineering and non-technical audiences.
Beneficial Skills & Qualifications
Experience authoring functional and technical specification documentation to a standard that enables independent implementation by distributed engineering teams.
Familiarity with site reliability engineering principles and a genuine interest in how reliability engineering shapes product development outcomes.
A bachelor's degree in Computer Science, Engineering, or a related technical discipline, or equivalent practical experience.
A master's degree or equivalent postgraduate qualification in a relevant technical field.
