Principal Solutions Architect

Role Overview

As a Principal Solutions Architect, you will specialise in the design, development and governance of integrated digital project controls environments across major capital programmes. This domain‑specialised architecture role focuses on Programme Management, PMO systems, Project Controls processes and EPPM technology ecosystems.

• Define enterprise‑aligned solution architectures for programme controls platforms covering cost, schedule, risk, performance reporting and data governance.
• Lead evaluation, selection, design and configuration of programme controls systems such as Eco Sys, Oracle Primavera P6, Unifier, Aconex, CDEs including SharePoint and Project Wise, and related digital delivery tools.
• Translate business, PMO and programme requirements into scalable, secure and maintainable solution designs aligned to enterprise architecture standards and major programme delivery strategies.
• Design and govern integration architectures across APIs, data pipelines, reporting tools and wider programme delivery systems to ensure seamless interoperability and consistency of controls data.
• Identify architectural risks, constraints and dependencies, develop mitigation strategies and ensure solutions meet performance, scalability, resilience and security requirements.
• Act as the technical authority for implementation teams, software vendors and delivery partners, ensuring solutions meet business, technical and quality specifications throughout the delivery lifecycle.
• Support digital transformation across PMO and project controls, including process harmonisation, standardisation, change adoption and optimisation of digital ways of working.
• Provide strategic architectural input across bidding, mobilisation and programme delivery phases, advising on technology roadmaps, solution options and implementation approaches.

• Strong experience designing and implementing Programme Management and Project Controls technology solutions, ideally within major capital programmes or complex delivery environments.
• Solid understanding of core project controls processes, including cost management, planning and scheduling, risk, change control, governance and performance reporting.
• Hands‑on experience with project controls and EPPM platforms including Eco Sys, Primavera P6, Primavera Unifier, Aconex and CDEs such as SharePoint and Project Wise.
• Ability to design robust technical architectures covering integration models, data structures, coding frameworks, workflow design and interoperability patterns relevant to project controls ecosystems.
• Experience assessing and optimising existing systems architectures, identifying opportunities to improve reliability, scalability and analytical capability.
• Background supporting digital transformation in PMO and project controls, including business process improvement, operating model changes and standardisation of ways of working.
• Excellent communication and stakeholder engagement skills, capable of articulating technical trade‑offs, solution options and dependencies to non‑technical audiences.
• Strong analytical and data modelling capabilities, with experience shaping structured programme data environments for integrated reporting and performance analytics.

• Experience designing, implementing or supporting PMO and Project Controls systems including Eco Sys, Primavera P6, Unifier, Aconex or equivalent EPPM technologies.
• Proven experience evaluating, configuring and deploying COTS and SaaS solutions using structured assessment, selection and implementation methodologies.
• Knowledge of enterprise architecture frameworks such as TOGAF, MODAF or NAF and their application within programme delivery and governance environments.
• Familiarity with Dev Ops‑aligned delivery practices and CI/CD concepts, particularly relating to integration environments, automated deployment models and cloud‑based delivery pipelines.
• Experience with reporting and analytics tools including Power BI, Tableau or equivalent BI platforms used for programme performance reporting.
• Strong understanding of integration technologies including API design, ETL processes, data…
