About the Role

We’re looking for a Frontend Software Engineer who is eager to level up to a senior role. You’ll be working on ambitious and creative ecommerce projects, marketing websites, and digital products, collaborating closely with experience designers, backend engineers, and DevOps teams to deliver cutting-edge digital experiences.

At Inviqa, you’ll have the opportunity to work on large-scale projects that involve deep collaboration with our Experience Design team, who specialise in customer research, UX, and UI design. Together, you’ll help validate the viability and feasibility of solutions before they go into development, ensuring that the digital products we create are both technically sound and user-centric.

Our clients span industries including food & beverages, hospitality, retail, and sports, and most have partnered with us for over five years. Many of our delivered projects enter a longer-term support and maintenance phase, giving you the chance to work on continuous improvement, performance optimisations, and iterative enhancements post-launch.

What You’ll Do

• Develop and maintain high-performance frontend applications using frameworks such as React, Next.js, and Tailwind CSS. React Router experience is a bonus but not essential.
• Implement server-side rendering (SSR) and static site generation (SSG) with Next.js to optimise performance and SEO.
• Work on headless ecommerce solutions, integrating with Shopify, BigCommerce, and leading headless CMS platforms like Contentstack, Contentful, and Sanity.
• Collaborate with the Experience Design team to refine UX/UI solutions, ensuring a seamless connection between design and development.
• Manage GitHub version control workflows, including branching, merging, and pull requests.
• Contribute to long-term support and maintenance of delivered projects, helping refine and enhance solutions over time.
• Occasionally engage in client-facing conversations to clarify requirements, ask questions, and ensure alignment with project goals.
• Contribute to internal learning initiatives, mentor junior developers, and help shape engineering communities of practice.
• (Optional) Take part in thought leadership activities, such as blogging, speaking at events, or sharing insights within the company.

What We’re Looking For

• Comfortable working in a fast-paced agency environment, with the ability to context switch between multiple projects.
• Experience working on large-scale digital projects, collaborating with designers, researchers, and backend engineers.
• A problem-solving mindset, with a focus on building scalable, maintainable, and user-friendly web applications.
• Ability to communicate effectively with clients, clarifying requirements and addressing technical questions in a professional manner.
• An openness to learning, mentorship, and contributing to the wider engineering community.
• UK-based, with a preference for flexible, remote-first working.

Why Join Inviqa?

By joining Inviqa, you’ll get to work on high-profile digital experiences for global brands across diverse industry sectors. Additionally, you’ll collaborate with a distributed team of engineers across the UK, Europe, and Asia.

We pride ourselves in flexible working arrangements – whether you prefer fully remote, hybrid, or occasional office time, we support a healthy work-life balance.

The Inviqa way encourages us to engage in continuous learning and development, with opportunities to lead learning initiatives, mentor others, and shape communities of practice.

Working at Inviqa means you become part of HAVAS, a global leader in marketing, advertising, and communications, giving you access to a broad professional network and finally you get to work on projects that have long-term value, where you’ll have the opportunity to contribute to both initial delivery and ongoing support and evolution of digital products.
