• Team Leadership: Mentor, supervise, and drive the output of a skilled engineering team, ensuring quality and adherence to industry standards.
• Cross-Functional Collaboration: Partner with PMs and Firmware/Electronics Engineers to ensure seamless integration of hardware and software.
• Customer Facing: Act as a technical authority, presenting designs and progress to both internal stakeholders and Ministry of Defence (MoD) customers.
• Modernization: Drive the adoption of modern practices, including Docker and containerization, within traditional embedded environments.

 
Your Technical Arsenal

• The Core: Expert-level C++ development within Linux/Windows environments.
• Design: Proficiency in structured design tools (specifically Enterprise Architect or similar UML tools).
• Domain Expertise: Proven experience in Embedded Real-Time applications and/or Acoustic Signal Processing.
• Process: Deep understanding of the full lifecycle—from requirement capture to V&V (Verification and Validation).
• Leadership: A track record of managing technical work packages and mentoring junior-to-mid-level engineers.
