EJH Engineering Consultants is a UK systems engineering consultancy. We help engineering teams and programme leads define, design, integrate and prove complex systems, bringing systems engineering, software development and electrical & electronic engineering together so the whole system works as one.

What our systems engineering consultants do

Systems engineering is the discipline that holds a complex programme together. It turns what stakeholders need into requirements engineers can build to, shapes an architecture that divides the problem sensibly, manages the interfaces between subsystems, teams and suppliers, and builds the evidence that the finished system does what it should. Our consultants do this hands-on, working inside your programme rather than alongside it.

Across the whole lifecycle

01

Requirements

Stakeholder needs turned into a clear, testable, traceable requirements baseline.

Requirements management → 02

Architecture

A system structure with clear responsibilities, interfaces and room to grow.

Systems architecture → 03

Integration

Interfaces defined and owned early, so subsystems come together as one.

Systems integration → 04

Verification & validation

Evidence that the system meets every requirement and the real operational need.

Verification & validation → 05

Safety & assurance

Structured safety arguments backed by traceable evidence.

Safety & assurance → 06

Software & electronics

Software and electrical & electronic design engineered as part of the system.

Software development →

Systems, software and electronics, engineered together

Many systems engineering consultancies stop at the system level. EJH also develops software and carries out electrical & electronic design, so the requirements, architecture and interfaces we define are the ones the software and hardware are actually built to. The result is fewer hand-offs, clearer accountability and a system that integrates smoothly.

When to bring in a systems engineering consultant

  • A new programme needs its requirements and architecture set up properly from the start.
  • Several suppliers or teams are delivering subsystems that must work together.
  • A design review, integration phase or acceptance milestone is approaching.
  • A customer, regulator or certification body needs traceable evidence.
  • Your team needs senior systems engineering capacity or mentoring for a defined period.

Why EJH

  • Senior engineering judgement, with no hand-off to junior delivery.
  • Across the whole system: systems, software and electronics considered together.
  • Evidence that stands up: traceability, verification and assurance built in from day one.
  • Commercially aware: decisions made with cost, schedule and risk in view.
  • Flexible engagement: scoped projects, embedded support or retained advisory.

Frequently asked questions

What does a systems engineering consultant do?

A systems engineering consultant makes sure a complex system is defined, designed, integrated and proven as a whole. That means turning stakeholder needs into clear requirements, shaping the system architecture, managing the interfaces between subsystems and suppliers, and planning the verification and validation that proves the system works and is the right system.

When should we bring in systems engineering consultants?

As early as possible: at concept and requirements stage, decisions are cheapest to change. Many clients also bring us in at critical moments, such as before a major design review, ahead of integration, when evidence is needed for acceptance or certification, or when an in-house team needs extra senior capacity.

Do you only do systems engineering?

No. EJH combines systems engineering with software development and electrical & electronic engineering, so the whole system, including the software and hardware within it, is engineered together.

Do you work across the UK?

Yes. EJH works with clients throughout the UK, on site and remotely, depending on what the programme needs.

Can you work within our existing processes and tools?

Yes. We adapt to your processes, tools and document standards rather than imposing our own, and leave your team with work they can own and maintain.

How do engagements work?

Most engagements are a scoped project with defined deliverables, embedded support that plugs into your team, or retained advisory access to senior judgement. We agree the scope, deliverables and cost before work starts.

Will you sign an NDA?

Yes. We're happy to sign a non-disclosure agreement before any detailed discussion, and early conversations are free and confidential.
