Deep hands-on expertise in .NET Core / C# or Java, with strong experience designing and delivering enterprise-grade backend systems and APIs.
Strong experience with microservices, distributed systems, and cloud-native application design.
Strong understanding of software architecture, scalable system design, engineering patterns, and how to apply them effectively in enterprise solutions.
Experience with relational databases such as PostgreSQL and MySQL, including strong SQL and data modeling skills.
Experience with Docker, Kubernetes, and one or more major cloud platforms such as Azure, AWS, or GCP.
Ability to guide technical design, influence architecture decisions, and mentor peers through hands-on technical leadership.
Strong analytical and problem-solving capabilities, including the ability to work independently and manage dynamic priorities.
Excellent communication, presentation, and documentation skills, with the ability to explain technical concepts to non-technical stakeholders.
Proven success using modern engineering and automation approaches to help teams reduce cycle time, increase reuse, and accelerate delivery in cloud-native and distributed system environments.

Responsibilities

Own technical direction and engineering outcomes for a defined DI&F product, platform, or capability area, ensuring solutions align with business needs, platform strategy, and engineering standards.
Design, develop, and enhance high-performance APIs and distributed platform capabilities used for fraud prevention, identity verification, and account validation.
Provide hands-on technical leadership through solution design, architecture guidance, code review, prototyping, issue resolution, and implementation support across the software development lifecycle.
Lead the design and evolution of microservices-based distributed systems using cloud-native architecture and modern engineering practices.
Work closely with architects, product owners, and quality leads to decompose solutions into epics, lead design planning, and break initiatives into executable journeys for engineering teams.
Own delivery of critical platform capabilities, working with a high degree of autonomy while mentoring others and helping ensure timely completion of work across the team.
Improve engineering quality, resilience, performance, observability, security, and reusability through shared patterns, technical standards, and strong implementation discipline.
Drive a security-first and risk-aware engineering approach by evaluating design trade-offs, resolving blockers, and building resilience and operational readiness into systems and delivery practices.
Build and deploy containerized solutions using Docker and Kubernetes across cloud platforms such as Azure, AWS, or GCP.
Ensure code quality through adherence to SOLID principles, sound design patterns, automated testing, and engineering quality tooling such as SonarQube and Coverity.
Use data, experimentation, customer feedback, and operational insight to validate assumptions and continuously improve systems and engineering methods.
Build strong relationships with internal and external stakeholders and communicate complex technical information clearly to both technical and non-technical audiences.
Mentor engineers and raise the bar for technical quality, delivery practices, and engineering capability across the team.
