• 3–5 years experience in a hardware-focused technical support, diagnostics, or test/validation role
• A working appreciation of software systems and connectivity sufficient to understand integrated hardware/software products
• Excellent interpersonal and communication skills, with the ability to translate technical findings for engineers and customers at all levels
• A proactive, ownership-driven mindset with confidence to make diagnostic calls in ambiguous situations
• Experience contributing to or building new processes and functions, rather than simply operating within established ones
• Strong organisational skills and the ability to manage multiple cases simultaneously while maintaining customer experience

Responsibilities:

• Capture and interpret CAN bus traffic from our hardware using Vector tools, identifying fault signatures and root causes at the message and signal level
• Decode CAN messages against DBC files and translate findings into structured, actionable reports for our engineering teams
• Act as the first point of escalation for inbound technical support queries, distinguishing genuine hardware and software faults from user error or configuration issues
• Determine whether issues can be resolved remotely or require field service deployment based on diagnostic evidence
• Liaise with our outsourced field service partner to coordinate site visits with clear technical briefs that reduce repeat visits and diagnosis time
• Build and maintain customer relationships, keeping communication proactive and solution-focused
• Work with the Head of Aftersales to design help desk processes, workflows, and escalation procedures
• Build a knowledge base of common CAN fault signatures and resolution paths to support consistent diagnosis as the team grows
