Senior Software Engineer C++

London /
Science & Technology – Cyber & Quantum Technologies /
In this role, you will be part of the group that develops, maintains and supports our flagship cybersecurity platform. You will work closely with your colleagues to design and implement new features, as well as troubleshooting issues and solving problems.  You will undertake other related tasks that are typical for a software engineer.  This will involve collaborating closely with our internal architects, establishing testing pipelines for new software, etc.  Your manager is technical and
Overall, our main development language is C++, and therefore a good understanding of C++ is required.  We have different products for different use-cases, with our main product being cloud-based and written in C++ with some Rust.  We also have client-based software, again written predominantly in C++. 
We maintain CLIs rather than GUIs for our tools, and GUI experience is not required, though naturally if you have experience in this area it would be good to hear it!  We use relatively standard development practices that will be familiar to most (Git, Artifactory, Jira for Kanban ticket management).  The team generally uses CLion for development, but you can use the tools that are best for you and the task at hand.  The software engineering manager comes from a technical background, having previously been a senior software engineer and technical lead themselves, and continues to use this knowledge to support the team.

Job Role and Responsibilities:

    • Working both independently and as part of the team to develop, maintain and expand Quantinuum’s cybersecurity software suite in a manner typical of a senior software engineer
    • Adapting to new programming languages and frameworks, as needed.  We will support you with formal (paid) and informal (internal) training, including the time to train.
    • Providing support and guidance to others in areas of technical expertise.
    • Identifying areas where personal improvement is necessary and working with the Manager to identify suitable training.
    • Presenting and demonstrating to others on your work and progress.
    • Taking ownership of projects or parts of projects to ensure effective delivery.
    • Working with internal stakeholders (Product and Solutions teams) to identify technical requirements for projects.
    • Working independently, or as part of a team, to design products and integrations.
    • Ensuring code quality through development of automated tests and participation in peer reviews.
    • Keeping tickets up-to-date with current status.  Creating new tickets as necessary.
    • Identifying areas of potential improvement throughout our products and work processes, and informing others of your findings.
    • You may be asked to mentor or guide junior members of the team.
