Solution​/Modernization Architect; C++ projects

Solution/Modernization Architect (C++ projects)

Location:

Poland (Krakow business trip occasionally).
Engagement type: part-time on pre‑sales activities, discovery phase; full‑time as more load appears. Contract agreement.

• Lead architecture and discovery phases for C++ platform modernization programs, covering application structure, dependencies, integration points, runtime behavior, and non‑functional constraints.
• Assess existing internal C++ systems, including monolithic applications, shared libraries, internal frameworks, batch or background processes, service layers, interfaces, and platform dependencies.
• Define target‑state architectures for modernization of legacy platforms, with a focus on Java‑based solutions, modular system design, service enablement, cloud readiness, and long‑term maintainability.
• Design modernization strategies tailored to each platform, including incremental refactoring, modularization, service extraction, phased migration, partial rewrite, coexistence patterns, and strangler‑style transformation.
• Evaluate and define the role of AI‑assisted code transformation within the modernization approach, including its applicability, risks, review process, and quality controls.
• Define approaches for modernization of legacy business logic, internal APIs, service interfaces, integration flows, and platform components while preserving critical business behavior.
• Facilitate workshops, architecture reviews, and solution design sessions with both technical and business stakeholders.
• Provide architectural guidance to engineering and delivery teams during implementation, helping ensure that modernization decisions remain aligned with the intended target architecture.

• 5+ years of experience in solution architecture, modernization architecture, or enterprise application transformation.
• Proven track record of designing complex modernization or migration solutions in enterprise environments.
• Strong understanding of legacy application modernization challenges, especially for large C++‑based internal systems with long‑lived business logic and significant technical debt.
• Strong understanding of modern Java‑based architectures and target‑state design principles for enterprise platforms.
• Experience in defining different modernization strategies.
• Ability to evaluate and communicate architecture trade‑offs related to maintainability, performance, state handling, concurrency, interoperability, and operational complexity.
• English – C1;
  Polish – C1/C2.

• Direct experience with C++ to Java modernization or similar legacy‑to‑modern language/platform transformation programs.
• Familiarity with AI‑assisted code transformation practices or tooling used in modernization initiatives.
• Familiarity with modernization‑supporting tools for static analysis, dynamic analysis, dependency mapping, and architectural assessment.
• Experience with modernization of integration‑heavy systems, internal APIs, messaging flows, and hybrid platform architectures.
• Experience with AWS or other cloud target environments used for platform modernization.
• Experience with performance‑sensitive or highly concurrent enterprise platforms.
