About the Team

This team operates

within a highly collaborative, scaled agile

environment where engineers are actively involved in both designing solutions and building them. Work is

not siloed—team members collaborate closely, openly communicate, and

proactively pick up work from the board.

The team plans in 10-week roadmaps and holds biweekly planning and refinement sessions.

Engineers are expected to take ownership by identifying available work,

delivering it, and holding high standards for quality.

Key cultural values include:

• Collaboration and open dialogue

• Proactive ownership of work

• Agile delivery with a focus on maintainability

• Quality over speed—building long-term, sustainable systems

Key Projects & Technical Focus

Work may rotate

between initiatives, but current strategic priorities include the Digital Associate Experience, which powers

daily workflows for bank associates.

Key goals include:

• Understanding and improving how banking associates work

• Streamlining workflows that currently span 25+ systems into a unified “single pane of glass” experience

• Supporting lending and leasing use cases

• Enhancing Customer 360 capabilities—providing a holistic view of customer relationships, loans, and leases

This work has a broad organizational impact and spans multiple

agile teams.
