Job Description

We are seeking a versatile Technical Pre-Sales and Field Application Engineer to build technical credibility, shape customer requirements, and enable sales conversion.

Supporting the full customer lifecycle — from early opportunity discovery through deployment, integration, and ongoing technical success — this hybrid role combines the customer-facing solution design strengths of pre-sales with the hands-on technical delivery and support capabilities of a Field Application Engineer (FAE).

You will collaborate closely with the sales, engineering, and operations teams, acting as both a technical evangelist and trusted advisor. The ideal candidate can translate business problems into technical solutions, deliver compelling demonstrations, and provide expert implementation and troubleshooting support.

Key Responsibilities:

Customer Discovery & Technical Positioning

• Support the sales team during customer engagements to identify requirements, challenges, and objectives.
• Lead technical discovery sessions, evaluating environments and integration constraints.
• Translate customer needs into Oakdoor solution architectures and value‑driven propositions.

Solution Design, Demonstrations & Proposals

• Create maximum value for customers by building compelling technical solutions that leverage the Oakdoor portfolio.
• Deliver compelling demonstrations, workshops, and proof-of-concepts to de-risk and accelerate opportunities through technical validation.
• Produce technical documentation including architectures, BoMs, implementation approaches, and content for RFP/RFI responses.
• Clearly articulate Oakdoor’s competitive advantages and technical differentiators.

Technical Implementation & On‑Site Support

• Support customers during installation, configuration, commissioning, and system integration.
• Perform diagnostic analysis, troubleshooting, issue resolution, and system validation.
• Conduct testing, performance checks, and acceptance procedures.
• Provide both remote and on‑site assistance as required.

Customer Enablement & Long‑Term Success

• Deliver technical training and knowledge‑transfer sessions for customers and partners.
• Advise customers on best practices, product optimisation, and operational efficiency.
• Build strong, trusted relationships with customer engineering and operations teams.

Internal Collaboration & Product Feedback

• Act as an extension of the Oakdoor engineering and support teams, building deep understanding and trust with customers and technical leaders.
• Capture insightful feedback to help inform and prioritise key technology and product roadmap decisions, including enhancements and new features.
• Analyse market trends, competitor activity, and customer needs to inform our wider business strategy.
• Support internal teams during opportunity qualification, solution validation, and technical reviews.

Technical Authority & Continuous Learning

• Maintain expert-level knowledge of Oakdoor products, integrations, and use cases.
• Stay current with relevant technologies and industry trends, such as cybersecurity, networking, and hardware/software systems.
• Contribute to internal enablement, technical guides, and reusable solution assets.

Qualifications

• Strong technical background in hardware, software, cybersecurity, or systems integration.
• Previous experience in a Technical Pre-Sales, Solutions Engineer, FAE, Systems Engineer, or similar customer-facing technical role.
• Demonstrated ability to design architectures and deliver hands-on implementation support.
• Excellent troubleshooting, analysis, and problem-solving abilities.
• Confident communication skills, with the ability to present complex topics clearly to both technical and non-technical audiences.
• Experience preparing proposals, diagrams, and technical documentation.
• A hands-on, agile, sleeves-rolled-up attitude to getting things done in a rapidly changing and evolving environment.
• You must be eligible for UK Security Clearance.
