Core Responsibilities

Primary Functions

Define and drive the overall technical and architectural vision for a specific product domain or a suite of enterprise applications.
Lead the design and implementation of high-performance, scalable, and highly available distributed systems and microservices architectures.
Create and maintain comprehensive architectural documentation, including system diagrams, data flow models, and technology stack specifications.
Act as the primary technical authority during all phases of the software development lifecycle, from initial ideation and requirements gathering to deployment and post-launch support.
Evaluate and recommend new technologies, tools, and frameworks to enhance our systems, improve developer productivity, and maintain a competitive edge.
Establish and enforce architectural standards, design patterns, and best practices across multiple engineering teams to ensure consistency and quality.
Conduct in-depth architectural reviews and provide constructive feedback on designs proposed by engineering teams, ensuring alignment with the strategic vision.
Collaborate closely with product managers, business stakeholders, and executive leadership to ensure that the technical architecture directly supports business objectives and user needs.
Lead technical discovery and proof-of-concept projects to de-risk new technologies and validate architectural approaches for complex problems.
Mentor and coach senior and principal engineers, fostering a culture of technical excellence, innovation, and continuous learning within the organization.
Champion non-functional requirements such as security, performance, scalability, reliability, and maintainability throughout the design and development process.
Own the long-term technical debt backlog, creating strategies for its remediation and balancing feature development with system health improvements.
Facilitate cross-team communication and resolve technical disagreements, ensuring that architectural decisions are made collaboratively and are well-understood.
Design and oversee the integration strategy for connecting disparate systems, both internal and external, through robust and well-defined APIs.
Define the cloud architecture strategy, guiding teams on the optimal use of cloud services (e.g., AWS, Azure, GCP) for cost, performance, and security.
Develop and maintain a multi-year technology roadmap that anticipates future business needs and industry trends.
Act as the key technical liaison with external partners, vendors, and clients, articulating our system's capabilities and architectural integrity.
Lead incident post-mortems for major system failures, identifying root causes and driving architectural changes to prevent recurrence.
Drive the "build vs. buy" decision-making process by conducting thorough analyses of third-party solutions against in-house development efforts.
Govern the evolution of the system architecture, ensuring changes are intentional, well-communicated, and adhere to established principles.

Secondary Functions

Support ad-hoc data requests and exploratory analysis to inform strategic decisions.
Contribute to the organization's broader technology strategy, intellectual property portfolio, and open-source initiatives.
Collaborate with business units to translate ambiguous or emerging data needs into clear, actionable engineering requirements.
Participate actively in sprint planning, retrospectives, and other agile ceremonies to provide architectural guidance and unblock teams.
Assist in the recruitment, interviewing, and onboarding of senior technical talent to grow the engineering organization.
Develop and deliver technical presentations and training sessions to both technical and non-technical audiences.

Required Skills & Competencies

Hard Skills (Technical)

Cloud Architecture: Deep, hands-on expertise in designing and deploying complex solutions on at least one major cloud platform (AWS, Azure, or GCP).
System Design & Modeling: Mastery of architectural patterns (e.g., Microservices, Event-Driven, SOA), data modeling, and UML or C4 modeling.
Containerization & Orchestration: Proficient with Docker, Kubernetes, and associated ecosystem tools for building and managing containerized applications.
API Design & Management: Strong knowledge of REST, gRPC, and GraphQL, along with experience using API gateways and management platforms.
