Job description

About the Opportunity

As a Solutions & Infrastructure Engineer, you will play a key role in designing and delivering secure, supportable and commercially viable technology solutions for our clients.

This is a hybrid position combining the technical depth of an experienced infrastructure engineer with the design and consultancy responsibilities of a solutions engineer.

You will contribute across the lifecycle of client engagements, from technical discovery and solution design through to implementation, validation, handover and ongoing service improvement.

Solution Design is a primary focus of the role, alongside the delivery of complex infrastructure, cloud and modern workplace projects. You will also provide specialist technical capability to the wider engineering team where your expertise is required.

You will work closely with the Technical Delivery Manager, Account Management, Service Desk and other engineers to ensure proposed solutions are technically sound, secure, supportable and aligned with Aabyss standards and service capabilities.

The role is ideal for an experienced MSP engineer who enjoys both designing solutions and remaining technically hands‑on.

Key Responsibilities

Solution Design & Consultancy

• Participate in client discovery workshops, technical assessments and solution planning.

• Design secure, scalable, resilient and supportable technology solutions.

• Translate identified client requirements and technical risks into viable technical approaches.

• Produce and contribute to Statements of Work (SoWs), technical designs, implementation requirements and network diagrams.

• Define technical scope, assumptions, dependencies, risks and high‑level effort requirements.

• Provide technical input into project scoping and solution recommendations.

• Support Account Management with technical consultancy and solution development.

• Present and explain technical recommendations to clients and internal stakeholders where required.

• Ensure proposed solutions align with Aabyss technical standards, operational services, support capabilities and strategic technology direction.

• Escalate designs where requirements, risks or dependencies fall outside established standards or capabilities.

• Contribute to design reviews and provide peer review for solutions produced by other suitably competent engineers.

Commercial pricing, contract negotiation and commercial approval remain outside the accountability of this role.

Complex Planned Work & Project Delivery

• Deliver complex infrastructure, cloud, networking and modern workplace projects.

• Lead technical implementation activities across multiple technologies.

• Implement approved designs in accordance with agreed scope and technical standards.

• Identify and elevate risks, dependencies or design issues discovered during delivery.

• Ensure technical work is completed to agreed quality standards.

• Test and validate delivered solutions before transition into ongoing support.

• Complete appropriate technical documentation and knowledge transfer.

• Ensure solutions are supportable before handover into live service.

• Provide specialist technical support to other engineers involved in project or planned work.

Technical Assurance

• Review technical solutions for supportability, resilience, security and operational risk.

• Identify technical assumptions, dependencies and risks before implementation.

• Challenge solutions that introduce unnecessary complexity, unsupported technology or avoidable operational risk.

• Contribute to the development and improvement of approved technical standards, patterns and implementation approaches.

• Support the Technical Delivery Manager in maintaining consistent technical quality across solution design and delivery.

• Capture learning from delivery outcomes and use it to improve future solution design.

Specialist Escalation & Incident Support

• Provide specialist technical capability for exceptional, complex or high‑impact incidents where additional expertise is required.

• Support Major Incident response when specialist technical input is required.

• Provide technical consultation and assistance to Service Desk and Engineering teams without automatically assuming ownership of operational tickets.

• Diagnose complex issues spanning cloud, infrastructure, networking, security and identity platforms where specialist intervention is appropriate.

• Identify underlying technical problems and contribute to long‑term remediation and service improvement.

This role is not a routine Service Desk escalation tier. Solution Design and planned technical delivery remain the primary focus of the position.

Security by Design & Technical Risk

• Ensure security is considered throughout solution design and technical delivery.

• Design and implement security controls appropriate to client requirements, risk and agreed standards.

• Identify technical and operational security risks during discovery, design and implementation.

• Support security reviews, gap assessments and remediation activity.

• Contribute technical capability to Cyber Essentials and Cyber Essentials Plus initiatives where required.

• Design and deliver technologies including:

  • Conditional Access
  • Multi‑Factor Authentication
  • Intune security controls
  • Entra ID security controls
  • Secure remote access
  • Email security
  • Backup and disaster recovery

• Promote secure, supportable and proportionate technical solutions.

Technical Leadership & Continual Improvement

• Mentor and support engineers across technical disciplines.

• Share knowledge and help develop technical capability across the engineering team.

• Contribute to technical documentation, standards, patterns and best practices.

• Participate in continual service improvement activity.

• Identify opportunities to improve consistency, efficiency, security and supportability.

• Help reduce dependency on individual technical knowledge by documenting and sharing repeatable approaches.

• Support the development of broader Solution Design capability across the engineering team.

Role Boundaries

The Solutions & Infrastructure Engineer provides primary day‑to‑day Solution Design capability but is not the sole source of Solution Design expertise within Aabyss.

Suitably competent technical resources may contribute to solution design, technical assurance and delivery within defined standards and controls.

The role:

• Does not own commercial pricing, contract negotiation or account management.

• Does not own overall project governance or delivery management.

• Does not replace the Technical Delivery Manager's accountability for technical delivery quality, standards and governance.

• Does not act as the default owner for Service Desk escalations.

• Does not assume ongoing ownership of live services following successful transition into support.

• Does not have authority to bypass established technical, change or service governance.

Experience & Skills Required

Essential

• Minimum 5 years' experience within an MSP or IT services environment.

• Proven experience designing and delivering complex infrastructure, cloud or modern workplace solutions.
