Architect and Lead Software Engineer

As anArchitectand Lead Software Engineeron a large-scaleplatform ofmodernization engagement, you will drive the end-to-end architecture from thedata layerthrough the API and services tier to thefront-end presentation layer. The client environment spans both Microsoft Azure cloud services andon-premisesinfrastructure, so you must be equally comfortabledesigningcloud-native workloads and hybrid integration patterns. You will lead architectural decision-making across multiple workstreams, produce reference architectures and migration roadmaps, and work hands-on with engineering teams tovalidatedesigns through prototypes and proofs of concept. This is a high-visibility role that requires you to present architectural options, trade-offs, and recommendations directly to senior technical andbusiness leaders.

What qualificationsmake youanAubrantArchitectand Lead?

• You are a full-stack thinker. You see thesystem, fromthe user interface to the database, and you design architectures thatoptimizeacross all layers rather than shifting complexity from one tier to another.

• You lead through technical authority. Engineering teams trust your judgment because you combine deep hands-on experience with the ability to articulate clear, defensible rationale for every architectural decision.

• You are comfortable navigating hybrid environments. You understand that modernization is rarely a clean lift-and-shift; you know how to design transitional architectures that bridgeon-premisesystems and cloud services without disrupting business operations.

• You communicate architecture in business terms. When you present to senior leaders, you translate technical trade-offs into cost, risk, timeline, and capability impact.

• You have a builder's instinct. Youvalidateyour designs with working prototypes and proofs of concept, not just diagrams. You believe architecture should be proven, not assumed.

• You thrive in ambiguity. Legacy modernization is messy; you bring structure, prioritization, and clarity to environments where documentation issparseand tribal knowledge is the norm.

Responsibilities:

Architecture & Design:

• Define the target-state architecture for the modernized platform, spanning front-end frameworks, API/services layer, data persistence,integrationmiddleware, and infrastructure (Azure andon-premise).

• Produce referencearchitectures, architectural decision records (ADRs), and migration roadmaps that guide engineering teams through phased modernization milestones.

• Design hybrid integration patterns that allow cloud-native andon-premisecomponents to coexist during transitional phases, including networking, identity, and data synchronization strategies.

Technical Leadership:

• Lead architectural reviews and design sessions across front-end, back-end, data, and infrastructure workstreams, ensuring consistency, quality, and alignment with the target architecture.

• Mentor and guide senior engineers and tech leadsonarchitectural patterns, modernization strategies, and Azure best practices.

• Evaluate and recommend technologies, frameworks, and platforms; produce decision memos with clear trade-off analysis for leadership review.

Modernization Execution:

• Conduct legacy system assessments, including codebase analysis, dependency mapping, performance profiling, and data architecture review, to informmodernizationsequencing and risk mitigation.

• Design andvalidatemigration strategies (re-platform, re-architect, re-factor) for individual system components, balancing speed, risk, and long-term maintainability.

• Build and oversee proofs of concept and reference implementations that de-risk critical architectural decisions before full-scale engineering begins.

Stakeholder Engagement:

• Present architectural strategies, options, and progress to senior technical and business leadership, translating complex technical concepts into clear business impact.

• Collaborate with the client's existing architecture, engineering, and infrastructure teams toalignstandards, governance, and shared technical direction.

• Partner with program management to ensure architectural decisions are reflected in delivery plans, resource needs, and risk assessments.

Qualifications:

• Bachelor's degree in computer science, Software Engineering, orrelateddiscipline, or equivalent experience.

• MUST be proficient in written and spoken English (85%).

• 10+ years of professional software engineering experience, with at least 5 years in asolutionsarchitect or enterprise architect capacity.

• Demonstrated mastery of architectural design across the full application stack: front-end (React, Angular, or equivalent modern frameworks), API/services tier (RESTful APIs, microservices, event-driven architectures), and data layer (relational databases, NoSQL, data pipelines).

• Deepexpertisein Microsoft Azure cloud services, including App Services, Azure Kubernetes Service (AKS), Azure SQL, Cosmos DB, Azure Functions, Azure API Management, Azure DevOps, and AzureNetworking(VNets, Private Link, ExpressRoute).

• Proven experience designing and implementing hybrid architectures that span Azure cloud andon-premiseinfrastructure, including identity federation (Entra ID/Active Directory), data synchronization, and network connectivity.

• Expert-levelproficiencyin API design and integration architecture, including API gateway patterns, service mesh, and enterprise integration patterns for bridging legacy and modern systems.

• Strong experience with application modernization strategies: monolith decomposition, strangler fig pattern, database migration, and phased re-platforming.
