About the Position

We are looking for a senior technical Program / Project Manager who can provide organization and coordination support for Change-The-Bank electronic trading infrastructure initiatives covering all technologies in this domain. 

The role sits within Citi’s Global Markets: High Performance Architectures – Infrastructure (HPAi) group.  This team is responsible for all electronic trading infrastructure architecture and engineering across all markets globally for the firm.  It is composed of low latency Subject Matter Experts (North America, EMEA) and Systems Architects (both regional and asset class aligned).   Technology is key to our business; this role will require you to foster delivery in a large multi-faceted and complex environment.  This ICG Tech “business aligned tech” resource will collaborate with ICG Markets “the business”, CTI “Enterprise Infrastructure”, and CISO “Security” teams tracking and driving technical delivery of CTB and End of Vendor Support (EoVS) initiatives where we choose to innovate. 

Reporting to the head of High Performance Architectures - Infrastructure, the TPM will perform Program Management functions, lead team SCRUMS, write executive summaries, etc.  The resource will additionally be responsible for the Markets connectivity team – ensuring timely delivery of connectivity requests.  All activities will be done in collaboration with CISO and CTS resources aligned to HPAi who represent Enterprise and CISO priorities and standards.  Active collaboration with all parties is required to be successful.  The resource should be able to effectively collaborate with the Markets-Tech Electronic Trading organization (our clients), steer other technology organizations directly or through influence, and love rolling up their sleeves and working as an individual contributor.  The resource will leverage the full strength of the supporting non-ICG technology organizations (dedicated and non-dedicated to HPAi).  The role is very broad requiring a resource that is not afraid to do new things and be challenged on a regular basis with a can-do attitude and an engineering mindset.  Ideal candidate has deep desire to drive results and an unquenchable desire to understand how technology primitives work (and how to abuse them).
