Full-time
What youll do
You will be a core member of the Credit Cards engineering team, a high-impact unit responsible for the full card lifecycle, from ordering and issuing to limiting, managing, and monitoring card transactions. The team integrates with third-party payment processors, 3D Secure systems, and MasterCard, ensuring seamless, secure, and high-performance card operations for our customers.
You will lead technical initiatives across card systems, designing, building, and validating robust backend solutions that scale with business needs.
You will work closely with architects, security, product, and operations teams to modernize the existing card systems into a new event-driven architecture, introduce cloud-native patterns. Build it from scratch while ensuring that card business services remain reliable, secure, and performant.
Who you are:
You are a seasoned Senior Backend Engineer with deep expertise in backend systems and cloud architectures. You thrive in complex, fast-moving environments and excel at turning ambiguous requirements into concrete, reliable solutions.
You bring strong technical ownership and accountability, balancing long-term architectural thinking with pragmatic delivery. You embrace change, learn quickly, and continuously adapt to new technologies, business needs, and integration challenges with external partners.
You are proactive, curious, and confident in making informed decisions. You influence others through technical excellence and clear communication, collaborating closely with product, architects, security, and operations teams to ensure alignment, adoption, and lasting impact.

You will be a core member of the Cloud Modernization Commando, an elite, high-impact engineering unit focused on accelerating cloud modernization across R&D teams in the organization. The team operates as a force multiplier, taking on complex, high-priority, and high-value cloud initiatives that require deep technical expertise, fast execution, and strong cross-team collaboration.
You will lead initiatives from a technical front, designing, building, and validating modern cloud patterns, unblocking critical initiatives, and shaping solutions that other teams can confidently adopt. This is not a long-term feature delivery role; stakeholders and missions change frequently. Instead, you will operate in a mission-driven model, engaging where impact is highest, creating momentum, and handing over sustainable ownership to product teams once the mission is complete.
You will work closely with architecture, platform, security, and product teams to modernize legacy systems, introduce cloud-native practices, and raise the overall cloud maturity across the R&D organization.
Who you are
You are a seasoned Senior Backend Engineer with a strong sense of ownership and accountability. You are comfortable operating in fast-moving, complex environments and excel at turning ambiguity into concrete, executable solutions.
You bring deep backend, cloud, and architectural expertise, balancing long-term thinking with pragmatic delivery.
You embrace change and learn quickly, continuously adapting to new technologies, architectures, and organizational needs. You are curious by nature, proactive in closing knowledge gaps, and comfortable making informed decisions even when not all answers are known yet.
You thrive in cross-team environments, earning trust through technical excellence and clear communication. You influence design, implementation, and example rather than authority, and enjoy collaborating closely with product, architecture, security, and infrastructure teams to ensure alignment, adoption, and lasting impact.
You are impact-driven, not territory-driven, measuring success by how effectively you enable other teams and improve the organizations cloud capabilities as a whole.
