Graduate Software Test and Development Engineer

About the Role

This is an exciting opportunity for a Graduate Software Test & Development Engineer to join a product development team working on software-controlled power systems used in long-life, safety-critical applications.

This role is well suited to someone early in their career who enjoys writing code, breaking software (on purpose), and understanding how software interacts with real hardware.

You don't need prior industry experience - training, mentoring, and hands-on support are built into the role.

You'll help develop and test the software used to manage power feeding equipment, which provides controlled electrical current to complex infrastructure systems.

Your work will directly contribute to system safety, reliability, and performance.

What You'll Be Working On

Based in Greenwich, you'll work closely with software developers, test engineers, and the wider product development team to:

• Develop and test software used to control power systems


• Carry out unit testing, integration testing, and system-level testing


• Help verify that software operates within defined safety and design limits


• Produce clear test evidence and compliance reports


• Identify bugs, unexpected behaviour, and opportunities for improvement

This is a hands-on role that blends software development, testing, and real-world system understanding.

What You'll Be Learning & Doing

With support from experienced engineers, you will:

• Plan and execute test cases alongside a Software Test Engineer


• Test software builds to ensure they are ready for release


• Support the software release process


• Investigate, reproduce, and evaluate software bugs


• Contribute to the development of software tools and utilities


• Perform system-level testing where software controls hardware behaviour


• Document results clearly and provide structured technical feedback

What We're Looking For

This role is designed for graduates - we're more interested in curiosity, problem-solving, and clear thinking than deep industry experience.

You might be a good fit if you can relate to some of the following:

Software & Programming

• Experience writing software in C and/or C++ (through university projects, placements, or personal work)


• Some familiarity with HTML


• Interest in or exposure to JavaScript / TypeScript and Linux (desirable, not essential)


• Enjoyment of debugging and understanding why something doesn't behave as expected

Testing & Systems Thinking

• An interest in software testing across firmware, software, and hardware boundaries


• Awareness of different testing levels (unit, integration, system)


• A methodical approach to validating behaviour against requirements

Hardware Awareness (Beneficial but Not Required)

• Basic electrical or electronic understanding


• Exposure to lab or test equipment such as oscilloscopes, power supplies, or multimeters


• Curiosity about how software controls physical systems

Key Responsibilities (With Support)

• Test software builds prior to release


• Support and follow structured software release processes


• Evaluate and document software bugs


• Assist with compliance and validation reporting


• Work collaboratively with software developers and test engineers


• Learn and apply safe testing practices in a system-level environment

What You'll Bring

• A degree (or Level 5 qualification) in Software Engineering, or Electronic Engineering with a software focus


• A logical, detail-oriented mindset


• Willingness to learn and ask questions


• Clear communication and good documentation habits


• Interest in building reliable, well-tested software

Why Join?

• A genuine graduate role with structured learning and mentoring


• Exposure to real-world, safety-critical software systems


• Opportunity to develop skills in software testing, development, and system validation


• A supportive, inclusive team environment based in Greenwich


• Work that has real impact on long-life engineering products
