Lead .Net Platform Engineer; Ingestion - Senior Vice President

About the Role

We are seeking an experienced, hands‑on Senior .Net Lead to contribute to the development of our engineering frameworks, with a strong focus on microservice architecture. This senior engineering leadership role merges hands‑on technical contribution with organizational accountability. The ideal candidate will remain deeply involved in the code and architecture while simultaneously owning the platform strategy, defining engineering standards, and guiding a scrum team in developing core functionalities within the payments lifecycle.

• Actively code in .Net developing reusable frameworks while performing system design, architecture reviews, and code reviews for the core cheque payment platform.
• Contribute to the design of distributed, fault‑tolerant, real‑time systems for high‑volume, low‑latency transaction processing.
• Write, review, and refactor production‑grade code in .Net setting a high technical standard for the team.
• Independently design event‑driven, microservices‑based architectures utilizing REST APIs, .Net. React knowledge is a plus.
• Apply hands‑on experience with Kafka, including message schema design, topic partitioning, consumer group strategies, and fault‑tolerant processing.
• Design and govern data architecture across Oracle (SQL) and MongoDB (No
  
  SQL), covering schema design, indexing strategies, query optimization, and data consistency patterns.
• Champion continuous development, feature flags, and progressive delivery, contributing to the design and optimization of CI/CD pipelines.
• Produce and review Architecture Decision Records (ADRs) and technical design documents for key platform components.

• Maintain and enforce engineering standards within the scrum team, including Test‑Driven Development (TDD), reusable framework development, CI/CD, secure coding, and observability.
• Conduct code reviews for critical platform components, providing detailed technical feedback to enhance team quality and capacity, ensuring the development of scalable and reusable services.
• Drive the adoption of AI‑powered quality practices, including leveraging tools like Git Hub Copilot for coding, utilizing LLMs (Gemini experience preferred) to improve payment processing quality, and implementing automated test script generation and vulnerability remediation.
• Lead performance engineering initiatives, including profiling JVM‑based applications identifying performance hotspots, and optimizing critical settlement processing paths.
• Own the security and compliance posture of the cheque payment platform by participating in threat modeling, vulnerability assessments, and secure design reviews.
• Ensure all engineering delivery aligns with Citi Engineering Excellence Standards, including CI/CD, Dev Ops, cloud‑native practices, and modern ways of working.

• Define and own the engineering roadmap for modernizing the cheque payment platform, migrating global components from monolithic mainframe and legacy applications to a reusable microservices architecture.
• Develop strong domain knowledge in the payment lifecycle, settlement, and cheque image processing to inform sound engineering decisions.
• Own the platform's SLA commitments, driving architectural decisions to meet availability, throughput, and latency targets.
• Develop cross‑platform integration by governing API contracts, data flows, and system dependencies across the Payments, Settlements, DDA, and Data Lake ecosystems.
• Drive capacity planning and investment prioritization, making informed decisions on platform scaling, technology refresh, and resource allocation.
• Partner with Operations, Risk, Compliance, and Business teams to ensure the platform meets all regulatory requirements and business needs.

• Act as the primary engineering point of contact for the core Cheque Processing pillar, engaging with senior business, technology, and operations stakeholders.
• Clearly communicate platform health, delivery progress, engineering strategy, and risks to senior leadership.
• Partner with Product, Operations,…
