About the Role

In 2021, Costello Medical launched its own in-house Technical Innovation and Development (TechDev) division. 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 an experienced Senior Front-End Developer, specialising in the Angular framework, to lead 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 in the Angular framework to build robust, scalable, and user-friendly interfaces
• Innovating and transforming. Use your innovative mindset to shape the future of technical advancement at Costello Medical. You will also support with the exploration and development of AI-driven solutions, further elevating our service offerings and setting new industry standards
• Forging strong partnerships. Work closely with key stakeholders from the get-go, offering technical insights whilst defining project visions and strategies
• Communicating with clarity. Act as the central pillar for clear communication, translating complex project requirements into actionable plans and addressing technical queries as they arise
• 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 unmatched customer service standards, balancing varied demands effectively to produce work of the highest quality
• Empowering and enlightening. Act as a mentor within your team, reviewing colleagues’ work with a constructive eye, as well as providing training and guidance to elevate the team’s capabilities
• Cultivating knowledge. Play a pivotal role in enhancing Costello Medical’s technical landscape by leading internal training sessions, sharing your knowledge and encouraging company-wide innovation

At Costello Medical, our technical solutions leverage industry-standard tools. 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. Our front-end is powered by Angular, which enables the creation of dynamic and responsive user interfaces. Our infrastructure, orchestrated with Kubernetes and Docker, ensures scalability across AWS and DigitalOcean cloud platforms.

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 recognise that home-working can improve work life balance, reduce commuting times and costs, and provide the opportunity to juggle personal commitments. At the same time, 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.

Therefore, we offer flexible working arrangements that allow our colleagues who have passed probation to work from home for up to half of the 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 for 1 day per week.
