Application Architect Lead

Introduction


Overview

The Application Architect needs broader enterprise application experience, strong problem-solving and stakeholder communication skills, and enough technical depth to work across applications, APIs/integration, data, cloud, and AI. We are looking for someone who can operate in ambiguous situations and turn a business need into an implementable solution, rather than someone who specializes primarily in one technology area.

How you'll make an impact

Responsibilities:

• Define and continuously enhance the organization’s AI-enabled SDLC.
• Establish context-engineering standards for existing applications.
• Structure business processes, requirements, source code, architecture, data, integrations, and operational knowledge for effective AI use.
• Embed with application teams to identify opportunities and implement practical AI-assisted solutions.
• Build AI agents, retrieval solutions, engineering workflows, evaluations, and automation.
• Integrate AI with repositories, documentation, testing, work-management, and CI/CD platforms.
• Measure improvements in delivery speed, software quality, testing, and developer experience.
• Evaluate emerging AI technologies and scale effective practices across teams.

About you

• Strong enterprise software engineering and production delivery experience (minimum 7 years).
• Hands-on experience with generative AI, agentic AI, retrieval, context engineering, and evaluation.
• Proficiency in .Net, C#, Java, JavaScript, TypeScript, or a comparable language.
• Experience integrating AI with applications, APIs, repositories, and enterprise data.
• Ability to quickly understand unfamiliar applications and business processes.
• Strong business acumen with the ability to engage non-IT stakeholders.
• Exceptional communicator who can clearly establish and drive adoption of standards.
• Comfortable operating in a fast-paced environment where AI technologies evolve rapidly.
