About us

Averna powered by Spherea designs, manufactures and supports complex test systems for aerospace, defence and other regulated industries.

The role

You will connect customer needs with the technical solution, translating operational and test objectives into clear requirements, architectures, interfaces and verification strategies for hardware, software, mechanical and production teams.

The role spans customer workshops, system design, technical reviews, laboratory integration, acceptance testing and commissioning. Regular in-person work alongside engineers and physical equipment is required; UK and international travel, including some overnight stays, may be required.

Key responsibilities

Work with customers and stakeholders to understand products, test objectives, operating environments, constraints and acceptance expectations. Plan and lead requirements workshops, resolve unclear or conflicting needs, define concepts of operation and use cases, and translate needs into structured, verifiable system and subsystem requirements.

Establish requirements baselines and traceability; identify assumptions, dependencies, constraints, exclusions and customer obligations; control changes and assess their technical, cost and schedule impact. Develop system concepts and assess feasibility.

Define functional and physical architectures, decompose requirements across hardware, software, mechanical and operational elements, and document internal and external interfaces. Lead or contribute to technical trade-off studies and evidence-based recommendations.

Work with specialists to select technologies, instruments, interfaces and design approaches, balancing performance, safety, reliability, maintainability, obsolescence, cost and schedule. Ensure solutions can be manufactured, integrated, tested, commissioned and supported throughout their intended life.

Identify technical risks and mitigation actions, support modular and reusable solutions, and maintain technical coherence as detailed design develops. Support the full engineering lifecycle: stakeholder-needs analysis, concept of operation, feasibility, requirements, architecture, preliminary and detailed design, manufacture, integration, verification and validation, factory/site acceptance, commissioning, warranty and in-service support.

Prepare for and contribute to system requirements, preliminary design, critical design and test-readiness reviews. Define evidence needed to demonstrate design maturity, coordinate specialist inputs and ensure decisions, deviations, concessions and changes are controlled. Develop verification and ...
