Position Overview

We are looking for a Senior Enterprise Architect with strong experience designing enterprise-scale, cloud-native, and distributed systems. The ideal candidate will have deep practical expertise in Domain-Driven Design (DDD) , combined with knowledge of modern architecture methodologies, integration, data, cloud, security, modernization, and AI architectures.

Key Responsibilities

• Define current-state, target-state, and transition architectures aligned with business strategy.

• Apply DDD to complex business problems and translate business capabilities into domain-aligned technology architectures.

• Create architecture models using the C4 Model, including Context, Container, Component, and Deployment diagrams.

• Define application, integration, data, cloud, security, and technology architectures.

• Establish architecture principles, standards, reference architectures, ADRs, and technology roadmaps.

• Lead architecture reviews and provide technical direction to engineering and product teams.

• Evaluate architectural trade-offs across scalability, reliability, security, performance, cost, and maintainability.

• Guide legacy modernization and transformation initiatives.

Domain-Driven Design – Core Expertise

Strong practical experience with Strategic and Tactical DDD is required. The architect should be able to:

• Identify business domains, subdomains, core domains, supporting domains, and generic domains.

• Perform domain decomposition based on business capabilities and business processes.

• Define Bounded Contexts and establish clear ownership and boundaries between domains.

• Create Context Maps and define relationships between bounded contexts.

• Facilitate Event Storming and domain modeling workshops with business and technical stakeholders.

• Establish and maintain a Ubiquitous Language between domain experts, product owners, architects, and developers.

• Identify and model: Entities, Value Objects, Aggregates and Aggregate Roots, Domain Services, Application Services, Repositories, Domain Events, Domain Policies, Define Aggregate boundaries and transaction boundaries.

• Translate DDD models into microservices, modular monoliths, APIs, events, and data ownership boundaries.

• Understand when DDD is appropriate and avoid unnecessary domain complexity.

The architect should demonstrate how DDD drives the architecture, rather than using DDD only as a modeling or documentation technique.

C4 Architecture – Core Expertise

Strong hands-on experience with the C4 Model:

• System Context diagrams

• Container diagrams

• Component diagrams

• Deployment diagrams

• Architecture landscapes

• System and service dependencies

Experience with Structurizr, PlantUML, Mermaid, Draw.io, or Lucidchart is preferred.

• Strong practical experience with Domain-Driven Design and C4.

• Proven experience designing enterprise-scale distributed systems.

• Strong understanding of cloud, APIs, integration, data, and security architecture.

• Experience producing architecture models and technical documentation.

• Strong communication, stakeholder management, and technical leadership skills.

Ideal Candidate

A hands-on architect who can connect:

Business Capability → Domain → Subdomain → Bounded Context → System → Service → API/Event → Data → Cloud Infrastructure

and translate this into a practical, scalable implementation roadmap for engineering teams
