Application Architect

Application Architect is a senior technical leader responsible for the endtoend design, architecture, and technical integrity of complex enterprise applications. This role defines architectural patterns, drives engineering excellence across teams, and ensures applications are scalable, secure, maintainable, and aligned with enterprise standards. Application Architect collaborates closely with engineering teams, product owners, business stakeholders, and the Enterprise Architecture (EA) group to ensure technology decisions support longterm business strategy.

Experience Level: 18+ years

1. Key Responsibilities

Architecture & Design

• Own end-to-end application architecture, including conceptual, logical, and physical designs.
• Create high-quality technical design documents, sequence diagrams, integration flows, and architectural blueprints.
• Perform architecture reviews to ensure adherence to standards, scalability, performance, and security requirements.
• Define and enforce architectural patterns such as microservices, domain-driven design (DDD), event-driven architecture, and modular front-end architectures.
• Ensure consistency of technology choices, coding standards, and design conventions across multiple engineering teams.
• Provide architectural guidance during planning, grooming, and solutioning phases.

Collaboration & Stakeholder Interaction

• Partner with the Enterprise Architecture team to align application solutions with enterprise-wide principles, reference architectures, and strategic roadmaps.
• Collaborate with product management, business analysts, quality engineering, and DevOps teams to ensure cohesive solution delivery.
• Communicate architectural decisions, trade-offs, and technical risks to technical and non-technical stakeholders.

Engineering Excellence & Best Practices

• Recommend and institutionalize best practices for coding, design, performance optimization, and application security.
• Conduct code reviews across teams to ensure maintainability, readability, and alignment with architectural principles.
• Define shared libraries, reusable components, and design system conventions to promote consistency.
• Promote high-quality engineering through automation, CI/CD maturity, testability, and observability practices.

Technical Leadership

• Mentor senior and mid-level engineers on architecture, design, patterns, and problemsolving approaches.
• Provide hands-on technical leadership when needed debugging complex issues, reviewing critical PRs, or guiding performance tuning.
• Influence platform strategy, modernization roadmaps, and long-term engineering direction.

System Understanding & Problem Solving

• Maintain a deep, holistic understanding of interconnected systems, integration patterns, and data flows.
• Lead the design of high-availability, high-performance, mission-critical systems.
• Evaluate new tools, frameworks, and platforms to determine fit for purpose and long-term maintainability.
