About the Role In 2021, Costello Medical launched its own in-house Technical Development (TechDev) team. Since then, our talented team have created and developed innovative products and services that enrich our internal workforce and provide exceptional value to our external clients. Blending the power of software development, automation, and research, the TechDev team drives forward the application of technology, streamlining client project outcomes and boosting internal efficiencies across the company.

As the team continues to expand in both size and capability, we are seeking a motivated and ambitious Front-End Developer to support the development and optimisation of high-performing and scalable web applications. You will play a key part in shaping user experiences, enhancing application efficiency, and delivering innovative front-end solutions.

Key responsibilities will include:

• Engaging in all aspects of front-end development. Apply your expertise to build robust, scalable, and user-friendly interfaces
• Strong collaboration within the TechDev team. Work closely with Senior Developers to build product features and address a variety of challenges
• Delivering with distinction. Ensure the timely delivery of new products and services, adhering to budgets and project deadlines, all whilst maintaining an unwavering commitment to quality and professional integrity
• Championing exceptional service. Uphold outstanding customer service standards, balancing varied demands effectively to produce work of the highest quality

At Costello Medical, our front-end is powered by Angular with Typescript, which enables the creation of dynamic and responsive user interfaces. Meanwhile, on the back-end, we primarily utilise Node.js and Go for performance critical services, while Python is employed for AI and machine-learning solutions.

While prior experience with these technologies is a plus, joining our TechDev team means you'll have access to comprehensive training and support. We're committed to equipping you with the knowledge and skills needed to excel with our technology stack.

Hybrid Working Policy: We believe that having face-to-face time in the office holds many benefits and is central to ensuring that the community we have created, where people have a workplace they belong to and feel part of, is never lost. At the same time, we recognise that homeworking can improve work life balance, reduce commuting times and costs, and providing the opportunity to juggle personal commitments.

Therefore, we offer flexible working arrangements that allow our colleagues who have passed probation to work from home up to half their time, measured across a 2-week rolling period. During your probationary period (normally the first 6 months of the role), you will be able to work from home 1 day per week.
