Sword is a leading provider of business technology solutions within the Energy, Public and Finance Sectors, driving transformational change within our clients. We use proven technology, specialist teams and domain expertise to build solid technical foundations across platforms, data, and business applications. We have a passion for using technology to solve business problems, working in partnership with our clients to help in achieving their goals.
About the role:
As a Senior OT Architect, you will play a leading role in shaping how organisations design, evolve and secure their operational technology environments. This is a senior, client-facing position focused on discovery, architectural design and technical leadership across complex OT landscapes. You will work closely with senior stakeholders, delivery teams and engineering specialists to define practical, scalable solutions that reflect the realities of operational environments.
The role sits at the intersection of strategy and delivery — guiding architectural direction, supporting major programmes of work, and ensuring that designs are grounded, implementable and aligned to operational needs. You will act as a trusted technical authority across engagements, helping organisations understand their current environments, define improvement roadmaps and establish the foundations required to support long-term resilience and maturity.
Working within our IACS Community:
Our Industrial Automation & Control Systems (IACS) capability sits at the heart of how we support organisations operating complex OT and ICS environments. As part of this practice, you’ll be part of a community of experienced architects, consultants and engineers who collaborate across a wide range of operational settings. Knowledge gained from live environments is shared openly, helping shape how the practice continues to evolve.
Architects operate with a high degree of autonomy while remaining closely connected to the wider team — providing technical leadership, supporting delivery teams, and contributing to the development of standards, methodologies and architectural approaches across the practice. This is an environment where experience is valued, collaboration is natural, and individuals play a meaningful role in shaping how OT services are delivered.
As a Senior OT Architect, you will:
- Lead discovery engagements and define architectural approaches across complex OT environments
- Design end-to-end OT solutions aligned to operational requirements, safety considerations and long-term sustainability
- Partner with commercial and delivery teams to support technical proposals, scope definition and solution shaping
- Act as the senior technical escalation point across OT engagements
- Lead and oversee site surveys to understand OT systems, networks and asset landscapes
- Guide security and compliance assessments across operational environments
- Facilitate risk identification and support the development of mitigation strategies
- Develop architectural roadmaps to support capability uplift and long-term improvement
- Support the creation of governance models, policies, standards and operating frameworks
- Oversee third-party suppliers and technical partners across project delivery
- Present architectural approaches, findings and recommendations to senior stakeholders
- Provide technical leadership, mentoring and direction to OT consultants and engineers
- Work alongside project managers to ensure delivery aligns with scope, timelines and outcomes
Requirements
- Significant experience working within OT, ICS or industrial environments in an architectural, senior consultant or technical leadership capacity
- Strong background in one or more OT domains, such as:

- Excellent communication and stakeholder engagement skills
Desirable
- Significant experience within OT security, industrial environments or critical infrastructure
- Previous consultancy experience across sectors such as energy, oil & gas, chemicals, manufacturing or utilities
- Knowledge of recognised industry frameworks and standards including:
