Principal Enterprise Architect - Estimation Systems

job summary: Randstad is seeking a high-caliber Principal Enterprise Architect - Estimation Systems to serve as a key technical authority driving the R&D, design, and long-term evolution of advanced estimation platforms for a leading rail transportation client in the Washington, D.C. area. Sitting at the intersection of enterprise architecture leadership and advanced computational science, this role requires deep expertise in physics-based modeling, statistical algorithms, and real-time data processing. You will lead cross-functional engineering teams through major legacy-to-modernization transformations-bridging mainframes with modern cloud-native, event-driven architectures-while aligning solutions with enterprise standards (TOGAF, BizBOK, DAMA-DMBOK) across operational, planning, and financial domains.

location: Washington, Washington, D.C. job type: Contract salary: $75 - 85 per hour work hours: 9am to 5pm education: Bachelors

responsibilities: Architecture & Technical Leadership: Architect and evolve scalable, high-accuracy estimation platforms utilizing event-driven microservices, real-time data processing, and distributed systems patterns.

R&D & Algorithmic Innovation: Drive R&D initiatives applying advanced mathematics, statistics, optimization algorithms, and physics-based simulation models to solve complex, domain-specific estimation challenges.

Enterprise Standards & Governance: Establish and enforce enterprise architecture standards aligned with frameworks such as TOGAF, BizBOK, and DAMA-DMBOK within a SAFe (Scaled Agile) environment.

Domain & Solution Modernization: Lead large-scale rail transportation modernization efforts, designing integrated solutions that address complex multi-domain business challenges spanning operations, planning, and finance.

Legacy-to-Cloud Transformation: Formulate and execute transition strategies migrating legacy platforms (IBM Mainframe, TPF) to modern, cloud-native tech stacks (Java, Spring Boot).

Stakeholder & Technical Guidance: Act as the primary technical advisor to senior business and engineering leaders, translating complex requirements into architectural roadmaps while mentoring junior architects and engineers.

qualifications: Education: Bachelor’s degree in Computer Science, Engineering, Applied Mathematics, Physics, or a related quantitative field (Master’s degree preferred).

Experience: 15+ years of total IT experience, including 10+ years in senior enterprise or systems architecture roles.

Domain Expertise: Proven track record delivering enterprise-scale architecture solutions within the rail transportation industry.

Computational Depth: Demonstrated experience designing complex estimation, statistical, optimization, or physics-based modeling systems.

Modern Stack Proficiency: Deep technical knowledge of event-driven architectures, microservices, distributed systems, Java/Spring Boot, and real-time data frameworks alongside legacy systems (IBM Mainframe/TPF).

Frameworks & Agile: Working experience with enterprise frameworks (TOGAF preferred, BizBOK, DAMA-DMBOK) and 5+ years of experience operating within SAFe or equivalent Agile-at-scale environments.

Leadership & Communication: Outstanding problem-solving ability with proven success influencing executive stakeholders and leading cross-functional engineering teams.
