• Ensure environments are secure, well-structured, and cost-aware
• Act as a technical expert on cloud architecture decisions

Data & Platform

• Own and evolve the data technology stack (data stores, pipelines, access patterns)
• Ensure data systems are reliable, observable, and fit for analytics and product use

We're at an exciting stage in our growth as a digital HealthTech company, with increasing traction across clinical trials and life sciences. Over the past year, we've invested significantly in our application and data and infrastructure to support a scalable, reliable, and secure platform for the next phase of growth. We're now looking for someone to take ownership of that platform, continuing to scale the capabilities and operational maturity in a health tech environment., Little Journey was founded by Dr Chris Evans, a paediatric anaesthetist and researcher who witnessed first-hand the impact that procedural anxiety, poor preparation, and inconsistent communication can have on patient experience, engagement, and clinical outcomes. Partnering with Sophie Copley, an expert in human-centred product design, the healthcare platform was developed and demonstrated significant benefits in improving care efficiency, compliance and patient experience. It was rapidly adopted across the NHS supporting children undergoing surgery, before being expanded to support a wide variety of common procedures. Building on this initial success, Little Journey expanded into clinical trials, applying the same principles of personalised education, emotional support, and engagement to research settings. Our Life Science platform, Trial Flow, supports trial participants and their families across therapeutic areas, to alleviate the burdens they face as they navigate participating in a clinical trial. The platform is now a global solution, and we work with major pharmaceutical companies. Little Journey is a Series A HealthTech start-up, and we are a highly collaborative, mission-driven organisation with a team of about 30 (including Product & Tech, Sales & Marketing, Operations & Delivery). We aim to change the future of personalised paediatric care, one empowered family at a time. We value honesty and integrity, trust and accountability, reflection and learning, proactive thinking, and a deep commitment to helping others.
