This person is recognized as a team's authority and technical expert who drives innovation and organizational growth through their contributions.

· They get their adrenaline rush by coding away in IDEs. They spend majority of their time in writing non-feature code. They are hands all the time and collaborate by writing interfaces, tests (unit or acceptance) and architecture fitness functions, outside of meeting rooms. Tools like JDepend, ArchUnit, ADRs and NetArchTest make them feel at home.

· Domain driven design in their game. They code to enforce the contextual mappings and aggregates for each bounded context. They drive implementation of consumer driven contracts to allow for evolution and learning of the domain model with hyper speed while meeting our promises to other teams internally and customers alike.

· They are polyglot engineering gurus. they bring cutting edge engineering practices to life in multiple evolving frameworks – Feature flags, fitness functions and whatever is required to reduce the cost and increase the lifecycle value of next feature delivered by engineering teams.

· They love declarative paradigm and functional programming. No one can stop them from paying off technical debt and refactoring the code for better SDLC, performance and availability.

· Work on complex enterprise-wide initiatives spanning multiple services/programs and drives resolution

· Work with business/product owners to architect and deliver on new services to introduce new products and bundles

· Participate and contribute to team's agile process and decisions. Understand and contribute to Prioritization. Drive prioritization decisions and trade-offs in working with product partners

· Drive the architectural design, including dependent services, service interactions, and policies

· Contribute and lead Guild initiatives by engaging and mentoring Engineers at all levels to improve the craftsmanship of Software Engineering

· Simplify and improve the cost/benefit of a function/service/architecture strategy

· Venture beyond comfort zone to take on assignments across different areas of Software Engineering

· Take on organization-wide and public speaking engagements and publishes white papers and blogs on relevant and emerging technical topics

· Consult across teams and across organization lines to identify synergies and reuse opportunities

· Participate and contribute to Principal review architecture meetings and drive resolutions to enterprise-wide challenges and regulatory needs

· Write recommendations for job promotions based on an unbiased view of one's accomplishments

· Conduct technical interviews for hiring engineering staff and raising the performance bar

· Progressively grown career with proven design and development experiences in Java,,Springboot, Microservices, API, Distributed systems, event driven architecture, SQL, secure coding standards (e.g., OWASP, CWE, SEI CERT), and vulnerability management.

· Has an expert understanding and experience of DevOps best practices to guide developers and abstract application development from underlying hosting platforms and infrastructure. Infrastructure as code and cloud first software development knowledge experience preferred.

· Experienced in the skills required to implement advanced test set ups in production environment (e.g., A/B testing, canary releases, blue-green deployment, feature flags)

· Experience in Continuous Integration (CI) and Delivery (CD) concepts, and capabilities to support automation, pipelines, virtualization, and containerization

· Understands internals of operating systems (Windows, Linux, Mainframe) to write interoperable and performant code.

· Has skills to develop and evangelize on reference architecture and run principles to help teams adopt Engineering Principles from the start (poison pill, active/active/active, auto-scaling, self-healing, others)

· Understands use cases for advanced design patterns (e.g., service-to-worker, MVC, API gateway, intercepting filter, dependency injection, lazy loading, all from gang of four) to implement efficient code

· Understands and implements Application Programming Interface (API) standards and cataloging to drive API/service adoption and commercialization

· Has skills to engage engineers across Technology organization to promote standard software patterns and reuse of common libraries and services

· Has experience in leading and coaching teams to perform software planning and estimation for large scale complex programs

· Has skills to drive trade-off discussions to set right development capacity based on value drivers (e.g., regulatory, security, new business, market parity, technical debt)

· Has experience in design and execution of automation across multiple business areas and provides guidance on best methods and tools.

· Performance engineering experience to ensure applications are built to scale, run, and perform for varying demands

· Has skills to perform architecture and cost analysis for internal, hybrid, and public cloud environments

· Has skills to succinctly articulate architecture patterns of complex systems, with business and technical implications, to executive and customer stakeholders

· Has skills to define and drive advanced chaos and other operational testing practices to test points of failures, monitors, and system behaviors under adverse conditions (e.g., resource spikes, network congestion, component or infrastructure failure)

· Experienced in agile and modern SDLC practices (Scrum/Kanban/Continuous Delivery/DevOps/Quality engineering) and the delivery situations they are used for.To find US Salary Ranges, visit People Place.
