Job description

Would you like to kick start your career in a supportive, collaborative and innovative company?

Do you enjoy working as part of an enthusiastic, passionate, and collaborative team?

Join our Service Systems Team

The Services Systems Engineering team delivers technical solutions that improve how internal teams operate across the business. We work closely with product, platform, architecture, operations and business stakeholders to understand problems, design practical solutions, and build sustainable software that supports real business outcomes.

Our solutions range from system integrations and automation through to full application development, deployment, support and ongoing improvement. We encourage curiosity, ownership and innovation, and you will have the chance to contribute to better ways of working and help deliver products that make a meaningful difference to our internal users and customers.

This is a hands‑on Senior Software Engineer role within one of our product squads, operating as part of our Product and Platform model.

You will work closely with Product, the Team Lead and the Principal Engineer, who hold overall technical direction; your contribution is strong individual delivery, sound technical judgement, and raising the bar through the quality of your own work and the support you give peers.

You should care about more than the code itself. We’re looking for someone who delivers customer‑focused outcomes for internal users, seeks feedback, challenges assumptions constructively, and helps the squad make sensible trade‑offs between delivery, maintainability, reliability and business value.

You’ll thrive in a team that values ownership, collaboration and continuous improvement, with “you build it, you support it” central to how we work.

As Senior Software Engineer, you’ll be responsible for:

• Product squad delivery: Build and ship production code as a core hands‑on contributor within a cross‑functional product squad
• Automation and integration: Design and build automation and integration solutions across internal systems and third‑party platforms, reducing manual effort
• Performance and architecture: Apply sound performance and architectural judgement to keep what you build maintainable and scalable, in line with direction set by the Principal Engineer and Team Lead
• Hands‑on programming: Write clean, well‑tested code in Node.js, React, Python and Go, meeting our standards for performance, scalability and security
• Mentoring and knowledge sharing: Support junior and mid‑level engineers through pairing, code reviews and technical discussion, contributing to a collaborative engineering culture

We’d love you to have

• Strong hands‑on engineering capability: Current, active coding ability in Go, Node.js, React and Python — you should be comfortable being one of the most active coders in the squad
• Automation and integration skills: Experience building automation or integrations that improve business processes or connect systems reliably, including APIs and third‑party platforms
• Mentoring and support for others: A track record of supporting less experienced engineers through code reviews, pairing or informal mentoring, without needing to be the formal technical authority
• Collaboration and communication: Confidence working with cross‑functional stakeholders, and the ability to explain technical concepts in plain, business-friendly language
• Ownership and accountability: A genuine belief in “you build it, you support it”, with the discipline to monitor and resolve issues in what you own

We also acknowledge that the confidence gap and imposter syndrome are a real thing and can get in the way of us meeting fantastic talent, so please don't hesitate to apply – we would love to hear from you!

Work in a way that works for you

We recognise that everyone is different and that the way in which people want to work and deliver at their best is different for everyone too. In this role, we can offer the following flexible working patterns:

• Hybrid working
• Working flexible hours - flexing the times you start and finish during the day
• Flexibility around school pick up and drop offs

Working with us

Wherever you work, we want you to experience the freedom and autonomy to realise your potential. You will feel supported by a team that celebrates individuality, encourages different perspectives, and embraces every background.

If you have a disability or neurodiversity, we can provide support or adjustments that you may need throughout our recruitment process or any mitigating circumstance you wish for us to consider. Any information you share on your application will be treated in confidence. You can find out more about life at Softcat and our commitments to diversity and inclusion at jobs.softcat.com/jobs/our-culture/

Here at Softcat, we don't prohibit the use of AI (artificial intelligence) in our application process, as we understand how far it can go to creating a truly equitable candidate experience. That being said, as a culture‑driven organisation, we believe that the genuine essence of each person is what truly matters, so we highly encourage you to be as authentically you as possible when submitting your application to showcase your true and whole self.
