Are you a hands-on Software Engineer who wants to build great technology, solve interesting problems and help shape how an organisation engineers for the future?

Great Ormond Street Hospital Charity is looking for a Senior Software Engineer to join our Digital Experience Engineering team and play a key role in Driven by Data, our digital and data transformation programme.

You’ll initially have a major focus on Seamless Data—modernising how data moves between our systems and partners by replacing fragmented, manual integrations with secure, reliable and scalable services.

But the opportunity is broader than one programme. As a permanent member of our Engineering team, you’ll work across software, integrations, cloud technology and digital experiences—taking technical ownership of projects and helping shape the engineering standards and technology that support GOSH Charity’s future.

The salary for this role is £68,000per annum and we operate a hybrid working policy of a minimum of 2 days per week in the office.

In line with our EDI strategy and Total Reward policy, we calculate our salaries based on benchmarking data across the charity sector. To ensure fairness for existing staff and new joiners, we do not offer salaries above the advertised rate.

Key Responsibilities

• Design, build, test and run secure, production-grade software across front-end, back-end and integration services.
• Take technical ownership of projects from discovery and architecture through to deployment and ongoing support.
• Design and build APIs, integrations and automations that connect our systems and external partners, including work within our Driven by Data transformation programme.
• Build and operate solutions in AWS, using modern DevOps and Infrastructure as Code practices.
• Contribute to our digital experiences, including our website and future web technologies, working with multidisciplinary teams to build solutions around user needs.
• Make pragmatic architectural decisions, balancing user and organisational needs with security, accessibility, resilience, maintainability and cost.
• Help shape engineering standards across code quality, testing, security, observability, documentation and deployment.
• Mentor and support other engineers through code reviews, architecture discussions and collaborative problem-solving.
• Explore emerging technologies and approaches where they add genuine value, including automation, event-driven architecture and the responsible use of AI.
• Work with technical and non-technical stakeholders to understand the problem behind the request and develop solutions that deliver meaningful outcomes.

Skills, Knowledge and Expertise

• Strong experience delivering complex, production-grade software from technical design through to deployment and support.
• Strong full-stack engineering experience, with the ability to architect solutions across both front-end and back-end technologies.
• Experience designing and delivering REST APIs and systems integrations, including third-party or legacy systems.
• Strong experience designing and operating production workloads on AWS.
• Experience using Infrastructure as Code, ideally Terraform.
• Strong professional experience with Python and another backend language, alongside modern front-end development using frameworks such as React or Svelte.
• Strong DevOps experience and a you build it, you run it approach to engineering.
• Experience implementing event-driven or distributed systems.
• Strong understanding of software architecture, systems design, security and the trade-offs involved in building scalable, maintainable services.
• Strong stakeholder management skills, with the ability to collaborate with technical and non-technical colleagues and explain technical decisions clearly.

Our current stack includes Python, TypeScript/Node, React, PostgreSQL, AWS, Terraform, GitLab CI/CD and Docker. You don’t need to have used every technology, but you’ll need strong experience across a similar modern engineering stack.

DBS - note a Basic DBS check is required for this role.

• 30 days annual leave (plus bank holidays)
• A flexible approach to working arrangements.
• Access to our enhanced pension scheme
• Life assurance

Every day, around 750 children and young people from across the UK are seen at Great Ormond Street Hospital (GOSH). At Great Ormond Street Hospital Charity, we help the hospital go above and beyond for seriously ill children, enabling kinder and better treatments, bringing hope for children with the rarest and most complex illnesses, and making hospital a little bit easier and a lot more fun for the thousands of children who are treated at GOSH every year. Our staff raise vital funds to support ground-breaking research, cutting-edge medical equipment, and the creation of child-centred facilities to help save more young lives, and essential support services that help save childhoods too.

Together, we can help give seriously ill children the best chance, and the best childhood, possible.

Our commitment to Equity, Diversity and Inclusion

We believe that GOSH Charity and the charity sector more widely should reflect the diversity of patients, communities, and society at large. We also know that having a more diverse and inclusive workforce will make us more innovative, challenge the status quo, and enable us to deliver more impact. We encourage applications from people of all backgrounds. In particular, we encourage applications from those who are currently under represented within the charity sector as they may be marginalised by race and/or ethnicity, sexual orientation, disability, long-term health conditions, or socioeconomic status.

As a Level 2 Disability Confident Employer we are more than happy to make reasonable adjustments wherever possible throughout the recruitment process.
