TL;DR
- An aerospace engineer designs, develops, tests and supports aircraft, spacecraft, missiles and their systems. O*NET's tasks for the occupation run from formulating the conceptual design of aeronautical or aerospace products to meet customer requirements, through mathematical modelling, stress and environmental tests on models and prototypes, and diagnosing performance problems from field reports, to writing technical documentation and evaluating vendors. Prospects describes an industry that spans civil and military aircraft, defence systems, satellites and space vehicles.
- The responsibilities fall into seven groups across a product's life: requirements and conceptual design, analysis and modelling, detail design and integration, test, certification and compliance, in-service support and investigation, and documentation and the team. Aerospace is a family of specialisms, from aerodynamics, structures and propulsion to avionics, flight test, systems integration and space systems, and the advert should name the one it is hiring, because a stress engineer and a flight controls engineer are different candidates.
- Entry is usually a degree or degree apprenticeship in aerospace, aeronautical or a related engineering discipline, with the National Careers Service and Prospects both listing lower-level apprenticeship and college routes with further study. Accreditation by the Royal Aeronautical Society helps towards incorporated or chartered status, and Prospects notes that defence and some space roles need security clearance and that some technical roles specify normal colour vision. Write the advert around the specialism, the product, the phase of its life and the clearance, and set objectives on the deliverables, the evidence and the schedule.
An aircraft is certified, not just built. Every structure, system and component on it has to be designed to a requirement, analysed against it, tested to prove it, documented so a regulator can check it and supported for decades in service. The aerospace engineer job responsibilities follow that life, and the job description for an aerospace engineer is only useful when it says where in that life the job sits and which of the discipline's many specialisms it belongs to.
This article sets out the responsibilities using three primary sources, the US O*NET occupational database, the UK National Careers Service and the Prospects graduate careers service, groups them into seven duties, lists the specialisms, separates the aerospace engineer from the mechanical engineer, the avionics engineer and the licensed maintenance engineer, covers qualifications, registration and clearances, and gives a job description template with objectives.
Engineers work to requirements, and their own objectives should be as clear as the ones they design to. See how New Dynamics Goals & OKRs keep an engineer's objectives, evidence and reviews in one place across a long programme.
What does an aerospace engineer do?
O*NET describes the occupation as performing “engineering duties in designing, constructing, and testing aircraft, missiles, and spacecraft”, with research into the adaptability of materials and equipment and improvements to testing equipment and techniques. Its reported titles show the breadth: aeronautical engineer, aerospace stress engineer, avionics engineer, design engineer, flight controls engineer, flight systems test engineer, flight test engineer, structural analysis engineer and structural test engineer.
The Prospects profile calls aerospace “a broad multidisciplinary industry encompassing a range of engineering disciplines”, covering civil and military aircraft, missiles and defence systems, and satellites and space vehicles, with a focus on “improving safety, performance, fuel efficiency, speed and weight, while reducing costs and meeting customer and regulatory requirements”. The National Careers Service lists the day-to-day tasks: build and test prototypes using CAD software; analyse test results to improve aircraft structures and aerodynamics; research new types of fuel and ways to reduce engine emissions; manage projects and supervise engineers and technicians; develop new instruments and software for spacecraft; and plan and supervise maintenance programmes.
Aerospace engineer responsibilities: seven duties across a product's life
Grouped from the O*NET tasks and the two UK profiles, the work follows the product.
- Requirements and conceptual design. Analyse project requests, proposals and engineering data to determine feasibility, producibility, cost and production time, in O*NET's words; formulate the conceptual design to meet customer requirements and regulations; develop design criteria including testing methods, quality standards and completion dates.
- Analysis and modelling. Formulate mathematical models and computer analysis to develop, evaluate or modify the design: aerodynamics, structures and stress, thermal, propulsion, control laws. This is where the aerospace stress engineer and the structural analysis engineer in O*NET's titles live.
- Detail design and integration. Produce the design in CAD; support assembly, integration and installation of systems and components, as Prospects lists; resolve the issues that arise between disciplines when the parts meet.
- Test. Plan and conduct experimental, environmental, operational and stress tests on models and prototypes; contribute to ground and flight-test programmes to assess performance, safety and reliability; evaluate product data from inspections for conformance to engineering principles, customer requirements and quality standards.
- Certification and compliance. Produce the evidence that the design meets the airworthiness, environmental and customer requirements; communicate technical and regulatory advice to clients, teams and suppliers; evaluate and approve vendors by studying their past performance.
- In-service support and investigation. Diagnose performance problems from customer and field reports or by inspecting damaged products; plan and coordinate the investigation and resolution of technical problems; analyse in-service performance and support maintenance, repair and upgrade; contribute to incident and accident investigations where relevant.
- Documentation and the team. Write technical reports, handbooks and bulletins for engineering staff, management and customers; maintain performance records; direct or coordinate engineering and technical personnel in design, fabrication, modification and test. The National Careers Service includes managing projects and supervising engineers and technicians.

The specialisms
Prospects lists the areas an aerospace engineer may work in: aerodynamics, avionics, materials and structures, propulsion, systems integration, and space systems and spacecraft engineering; and notes that job titles vary, from aerospace design engineer and flight test engineer to propulsion engineer, systems engineer and test engineer. The National Careers Service adds fuel efficiency, satellite and space technology and air accident investigation as fields to specialise in with experience.
The advert should name the specialism in the title, because the candidates do not overlap: a stress engineer searches for stress engineer, not aerospace engineer. Name the product too, whether a civil airliner wing, a military platform, a satellite bus or an engine, and the phase of its life the job sits in.

Aerospace engineer vs mechanical engineer vs avionics engineer vs maintenance engineer
| Role | Works on | Distinctive knowledge |
|---|---|---|
| Aerospace engineer | Aircraft, spacecraft, missiles and their systems | Aerodynamics, flight, airworthiness and the certification process |
| Mechanical engineer | Machines and mechanical systems in any industry | Mechanics, thermodynamics, manufacturing |
| Avionics engineer | The electronic systems on aircraft and spacecraft | Electronics, software, control and communications |
| Licensed aircraft maintenance engineer | Aircraft in service | Maintenance, inspection and release to service under a licence |
Many aerospace engineers hold mechanical or electrical degrees, which the National Careers Service lists as accepted routes in, and the mechanical engineer job description and the electrical engineer job description cover those neighbouring roles. The difference is the environment the product operates in and the regulatory process it must pass.
Skills employers look for
Prospects lists strong technical knowledge of aerospace systems, materials and manufacturing processes; analytical and problem-solving skills for complex engineering challenges; creativity and innovation in developing, testing and improving designs; attention to detail and a methodical approach to ensure safety, quality and compliance; communication and teamworking in multidisciplinary teams; and the ability to manage time, adapt to change and meet deadlines, with language skills useful in international joint ventures. The National Careers Service adds knowledge of engineering science, maths and physics, design skills, analytical thinking, verbal communication and confidence with computer systems and software.
For the advert, add:
- Rigour with evidence. The habit of showing, not asserting, that a requirement is met.
- Tolerance for long programmes. Aircraft take years; the engineer has to keep the standard up through the eighth iteration.
- Working across disciplines, because every aerospace problem crosses at least two.
Hours and environment. Prospects describes standard office hours with extra hours at busy times and to meet deadlines, hybrid arrangements common, and occasional out-of-hours technical advice in in-service support, test or defence roles. The National Careers Service lists factories, offices, aircraft and hangars, sometimes in protective clothing.
Qualifications, registration and clearances
Entry. Prospects says many aerospace companies' graduate schemes require entry at level 6, through a degree or degree apprenticeship in aeronautical or aerospace engineering, with mathematics, physics or another engineering discipline often accepted; entry at a lower level is possible through apprenticeships or college courses at levels 3 to 5 with further study, often supported by employers. The National Careers Service lists degrees and postgraduate courses in aerospace engineering, avionics, electrical, mechanical or manufacturing engineering, physics, astronautics, software engineering or mathematics, and an HNC or HND before a trainee technician job. O*NET places the occupation in Job Zone four, usually a bachelor's degree.
Professional registration. Prospects notes that a degree or Masters accredited by the Royal Aeronautical Society helps meet the educational requirements for registration as an incorporated or chartered engineer. State whether the company supports it.
Clearances and requirements. Prospects says security clearance may be required for defence and some space roles, depending on the employer and the work, and that some technical roles specify normal colour vision. Put both in the advert if they apply; they decide who can take the job.
Progression. The National Careers Service gives specialisation, project management, consultancy and technical sales; Prospects adds that experienced and chartered engineers may work on a consultancy or contract basis.
