About the Team:

The Microservices Digital Software Engineer – Citi Retail Services is a seasoned engineering leader who brings both the depth of a hands-on technologist and the vision of a strategic architect to one of Citi's most consequential transformation programs. This is a role defined by duality: the ability to operate with precision within a complex, high-performance current-state environment while simultaneously charting the course toward a Next Generation target architecture. The ideal candidate does not simply maintain what exists — they elevate it, challenge it, and lead the charge toward what's possible. At Citi Retail Services, this individual will be a trusted technical voice in shaping how modern Microservices, containerized applications, and hybrid cloud solutions come together to power financial products that serve millions of customers.

The successful candidate will bring 8+ years of infrastructure management and software engineering experience and will operate at the intersection of technical execution and organizational influence. They will collaborate with cross-functional engineering squads, business partners, and technology leaders to drive the design, delivery, and evolution of enterprise-grade platforms — bridging the gap between today's production systems and tomorrow's cloud-native architecture. Their contributions will be felt across the application lifecycle, from system design and architectural trade-off analysis to performance engineering in high-throughput Java environments.

This is an opportunity to leave a lasting mark on Citi Retail Services' technology landscape. The engineer who thrives here will be someone who treats architecture as a craft, infrastructure as a strategic asset, and transformation as a shared mission — bringing technical excellence, collaborative leadership, and an unwavering commitment to innovation to everything they build.

Responsibilities:

• Accountable for executing and driving mid-size feature application design and development efforts to completion, serving as a development lead on medium-scale projects and supporting the execution of larger efforts.

• Proficient at operating with considerable autonomy and discretion as you will significantly influence the way an application is designed and developed by providing subject specific expertise and an advanced level of understanding of application programming principles.

• Sought after due to ability to analyze and troubleshoot coding, application performance and design challenges.

• Communicate progress, anticipate bottlenecks, provide escalation management, identify, assess, track and mitigate issues/risks at multiple levels.

• Recognize discordant views and take part in constructive dialog to resolve them.

• Work across teams to optimize processes.

• Regularly review metrics and proactively seek out new and improved mechanisms for visibility ensuring your program stays aligned with organization objectives.

• Continuously assess development processes, test plans, and operations.

• Work with teams to improve concurrent project delivery.

• Streamline and/or eliminate excess process in any area of architecture, build, delivery, production operations environment, or business area where the same efforts (or issues) are repeated year-over-year.

• Share knowledge with the team in various forums (brown bags, engineering forums etc.) and demonstrate a higher level of knowledge through industry certifications.

• Appropriately assess risk when business decisions are made, demonstrating particular consideration for the firm's reputation and safeguarding Citigroup, its clients and assets, by driving compliance with applicable laws, rules and regulations, adhering to Policy, applying sound ethical judgment regarding personal behavior, conduct and business practices, and escalating, managing and reporting control issues with transparency.

• Experience with integration technologies such as TIBCO, Apache Kafka, or MuleSoft, including designing event-driven and message-based architectures for high-volume, mission-critical financial services platforms.

• Strong knowledge of CI/CD tools including Jenkins, GitLab CI/CD, GitHub Actions, or ArgoCD, with experience automating build, test, and deployment workflows at scale across large engineering teams.

• Proficiency with relational and NoSQL databases such as PostgreSQL, MongoDB, Oracle, or Redis, including performance tuning, schema design, and data modeling for high-throughput transactional systems.

• Experience implementing monitoring and observability solutions using Prometheus, Grafana, ELK Stack, or Splunk, with a focus on ensuring system reliability, SLA adherence, and uptime in production environments.

• Experience conducting architectural trade-off analysis using structured models (e.g., ATAM, ADRs), with the ability to evaluate competing design approaches and recommend solutions that balance performance, cost, and maintainability.

• Skilled at working with third-party service providers and technology vendors to align implementation plans with strategic technology roadmaps.

• Excellent written and oral communication skills, with the ability to articulate complex technical concepts clearly to both engineering peers and non-technical stakeholders.
