As aÌýSystems Engineer II,Ìýyou’llÌýlead the architecture,ÌýintegrationÌýand verification of our hypersonic vehicle systems. Working across multiple engineering disciplines,Ìýyou’llÌýturn missionÌýobjectivesÌýinto practical solutions, define system requirements and interfaces, and ensure designs are delivered from concept through to verification.

Ìý

This is a rare opportunity to get hands-on withÌýcutting-edgeÌýhypersonic technology in a fast-paced, high-growth environment.ÌýIfÌýyou’reÌýdriven by innovation, thrive on tackling complex problems, and want the autonomy to make a real impact,Ìýwe’dÌýlove to hear from you.Ìý

WhatÌýyou’llÌýownÌý

Responsibilities include:Ìý

• Develop and maintain requirements documents, traceability matrices (RTM) and verification cross-reference matrices (VCRM) with our Requirements Management Tool.  Ìý
• Write clear, testable and unambiguous requirements that flow logically from parent requirements to design implementation. 
• Develop verification strategies (test, analysis, inspection, demonstration) and define acceptance criteria for each requirement.Ìý
• Work closely with design and test teams to ensure design choices are implementable and testable.Ìý
• Champion engineering rigor, technical documentation standards and continuous improvement within the systems team.Ìý
• Collaborate with suppliers and internal teams to define technical specifications, review designs and manage interface changes.Ìý
• Hands-on integration and testing of COTS avionics, sensors and electromechanical equipment into vehicle systems.Ìý
• Define system and subsystem architecture for vehicle platforms, including avionics, propulsion interfaces, fuel systems and test infrastructure. Ìý
• Decompose high-level mission requirements into subsystem and component specifications with clear performance budgets (mass, power, thermal, data rates). Ìý
• Develop interface control documents (ICDs) defining mechanical, electrical, data and fluid interfaces between subsystems and external/internal stakeholders. Ìý
• Make informed trade-off decisions on design alternatives using structured methods.
• Perform hazard analysis on flight and ground systems to identify failure modes, hazards and safety-critical functions.Ìý
