Job description

Accenture is expanding its Defense Technology practice with a visionary Lead Solution Architect to drive the next generation of mission-focused synthetic environments and AI-enabled platforms. In this role, you will play a critical part in shaping and delivering complex architecture for NATO defense organizations and leading global defense industry clients.

You will define the technical architecture for simulation, training, multi-domain operations (MDO), and AI-driven decision-support solutions. Our work is anchored in Accenture’s Common Synthetic Environment (CSE) — a strategic global asset developed collaboratively across our international engineering teams.

This is a unique opportunity to operate at the intersection of cutting-edge technology, national security, and large-scale digital transformation.

As a Lead Solution Architect, you will:

• Collaborate with client teams to understand requirements and define end-to-end simulation and AI architectures
• Design scalable, cloud-native synthetic environment platforms supporting training, operational planning, analytics, and wargaming usecases
• Shape architectural vision and platform strategies during sales and early engagement phases
• Guide and mentor development teams to ensure architectural integrity, compliance, and alignment with program objectives
• Lead architecture governance processes, including design reviews, decision records, standards, and best practices
• Oversee a team of architects across application, infrastructure, simulation, and data domains
• Contribute to the evolution of the CSE global asset, ensuring architectural consistency and technical excellence across markets
• Work with an ecosystem of industry-leading technologies and partners, including: NVIDIA, Palantir, Unity, Palantir, Varjo, Red Hat, Dell, OpenAI, OneArc, Plexsys, Battlespace Simulations, Hadean, Valkyrie Enterprises, and more.

What We Are Looking For:

• 10+ years of experience in senior architecture roles within complex, mission-critical environments
• Experience designing event-based, distributed, and federated system architectures
• Understanding of AI technologies and modern data platforms (e.g., Palantir, Databricks)
• Proficiency with architecture frameworks and modelling standards (Archimate, NAF, UML…)
• Background in DevOps, Infrastructure as Code, and secure-by-design engineering
• Solid programming fundamentals and ability to engage hands-on if needed
• Cloud expertise (OpenShift, Azure, or equivalent)
• Knowledge of system hardening, secure environments, and defense-sector requirements

Why Join Accenture?

• Collaborate with a global network of industry-leading experts in simulation, AI, and defense technologies
• Opportunity to work on mission-critical programs that directly support NATO nations and the broader defense ecosystem
• Access to the latest technology innovations, global R&D initiatives, and multi-domain operational programs
• A culture of continuous learning, career development, and cross-border collaboration
• The ability to make real impact — work that truly matters

All job ads will be reviewed in August. We encourage you to apply already in July, but please note that we will provide updates only from August onwards.
