Senior Application Architect - #26-14488

Duration: 6 Months
 
Job Description:

• We are seeking an experienced Senior Architect to lead the design and evolution of complex enterprise systems. The ideal candidate will have deep experience in architecting scalable distributed systems, working across multiple technologies, and guiding engineering teams in delivering high-quality solutions.
• This role places special emphasis on experience with Domain Driven Design (DDD) architecture and brownfield modernization projects, where new systems are designed to incrementally replace or modernize existing legacy platforms without disrupting business operations.
• The architect will collaborate closely with engineering teams, product managers, and business stakeholders to drive architectural decisions that align with business goals and long-term platform strategy.

Responsibilities:

• Design and implement scalable, resilient, and maintainable system architectures for enterprise applications.
• Apply Domain Driven Design (DDD) principles to structure complex domains into well-defined bounded contexts and services.
• Lead brownfield modernization initiatives, designing systems that incrementally replace legacy platforms while maintaining operational continuity.
• Define architecture patterns for microservices, APIs, event-driven systems, and distributed architectures.
• Partner with engineering teams to ensure architectural standards and best practices are implemented effectively.
• Evaluate existing systems and create roadmaps for modernization and technical transformation.
• Provide technical leadership, mentoring engineers and guiding architecture decisions across teams.
• Ensure systems meet requirements for scalability, performance, security, and reliability.
• Work closely with DevOps teams to define CI/CD, observability, and operational excellence standards.
• Participate in design reviews, architecture governance, and technical decision-making forums.

• 12 years of experience in software engineering, including significant experience in system architecture.
• Proven experience designing and delivering large-scale distributed systems.
• Strong experience applying Domain Driven Design (DDD) in real-world enterprise applications.
• Demonstrated experience working on brownfield systems, particularly projects involving incremental replacement or modernization of legacy platforms.
• Experience with API-driven architectures, microservices, and event-based systems.
• Strong understanding of software architecture patterns, system design principles, and design trade-offs.
• Experience working with modern cloud environments such as AWS, Azure, or Google Cloud.
• Excellent communication skills with the ability to collaborate with both technical and business stakeholders.

• Data Structures & Algorithms
  • Strong understanding of fundamental data structures and algorithms.
  • Ability to reason through problems and explain the selected approach.
  • Comfortable solving technical problems through whiteboard coding.
• Database Concepts
  • Strong understanding of database fundamentals, including:
  • Data modeling
  • Relational database concepts
  • Query optimization fundamentals
  • Indexing
  • Transactions and concurrency
  • Data consistency and integrity
  • Performance considerations
• Core Engineering Fundamentals
  • Strong software engineering fundamentals, with a solid understanding of:
  • Object-oriented design and programming principles
  • Design patterns
  • SOLID principles
  • Clean and maintainable code
  • API and service design
  • Scalability and performance
  • Reliability and fault tolerance
  • Security fundamentals
• Architecture & System Design
  • Strong experience in solution architecture and system design, with the ability to design systems considering:
  • Scalability
  • Performance
  • Availability
  • Maintainability
  • Security
  • Integration
  • Data management
  • Operational considerations
  • Ability to explain architectural trade-offs and justify design decisions.
• Problem-Solving & Engineering Mindset
  • The ideal candidate should demonstrate a structured and independent approach to problem solving. During technical discussions, the candidate should be able to:
  • Understand and decompose ambiguous problems.
  • Identify assumptions, constraints, and dependencies.
  • Evaluate multiple approaches.
  • Explain trade-offs clearly.
  • Arrive at practical and implementable solutions.
  • Think independently rather than relying solely on predefined processes or instructions.
  • Take ownership of the outcome from problem definition through implementation.
• Communication & Leadership
  • Strong communication and executive presence are critical for this role. The candidate should demonstrate:
  • Excellent verbal and written communication.
  • Strong presentation and storytelling skills.
  • Confidence when communicating with technical and non-technical stakeholders.
  • Clear and structured thinking.
  • Ability to articulate complex technical concepts in a simple and understandable manner.
  • Ability to explain and defend technical and architectural decisions.
  • Strong collaboration and stakeholder-management skills.
  • Ability to influence technical direction through sound reasoning and technical credibility.

• Data Structures & Algorithms
• Database Fundamentals
• Core Software Engineering Concepts
• Hands-on / Whiteboard Coding
• System & Solution Design
• Architecture Trade-offs
• Real-world Problem Solving
• Technical Communication & Presentation
• Ownership and Leadership Scenarios

• Bachelor’s degree in Information Systems, Computer Science, Business, Engineering, or related field, or equivalent experience.

• Experience leading architecture for large enterprise platforms.
• Experience with modern data architectures and distributed data systems.
• Familiarity with containerization and orchestration technologies (Docker, Kubernetes).
• Experience implementing observability frameworks (monitoring, logging, tracing).
• Experience mentoring teams and establishing engineering best practices.
