Job description

We’re excited to welcome a Senior Software Engineer to our newly forming Onsite Messaging team at Voyado.

Onsite Messaging (OSM) is one of Voyado’s most important customer engagement channels. Instead of communicating through email or SMS, OSM enables retailers to engage customers directly on their websites with personalized experiences based on real‑time behavior. Every interaction can be measured, understood and optimized, making OSM a key part of creating seamless customer journeys.

We’re now bringing OSM onto Voyado’s Engage platform, and we’re looking for an experienced frontend‑focused engineer who wants to help build the future of the product. You’ll join a small team with a high level of ownership, working closely with our Staff Software Engineer and colleagues in India to shape both the product and the engineering practices.

About The Role

This is a role for someone who loves building great frontend experiences while enjoying enough backend work to understand the full picture.

You’ll take ownership of the frontend for Onsite Messaging, building both the OSM editing experience inside Engage and the lightweight JavaScript that powers personalised experiences on customers’ websites. These solutions need to be fast, scalable, secure and reliable, serving millions of visitors across hundreds of retailer websites.

Although your primary focus is frontend development, you’ll also contribute to our backend APIs in .NET when features require it. You’ll work closely with the team to evolve the product, review code across our distributed team and help drive the transition of the project and migrating things onto Engage.

You’ll spend your first months learning the existing solution, collaborating with our engineering team in India and gradually taking ownership of larger parts of the frontend. Over time, you’ll become one of the main technical owners of the OSM frontend and continue building new capabilities as the product evolves.

Who you are

We’re looking for an experienced software engineer who enjoys building performant frontend applications while understanding how they interact with scalable backend systems.

You Don’t Need Experience From Our Exact Technology Stack, But We Believe You’ve Worked With Several Of The Following

• Modern frontend development using JavaScript and TypeScript
• Frameworks such as React, Vue, Angular or similar (experience with Aurelia is a bonus)
• Fullstack development with experience working in backend services when needed, ideally in C#/.NET or similar languages
• Public‑facing, high‑traffic web applications where performance, security and scalability matter
• Cloud platforms — we run some of our services on Azure, and some on AWS, including Lambda for our backend services
• Modern frontend tooling, build pipelines and component‑based architectures

We Also Think You

• care about clean, maintainable and high‑quality code
• enjoy giving thoughtful and constructive code reviews
• are curious about performance optimization and frontend architecture
• communicate well across teams and cultures
• thrive in collaborative environments with shared ownership
• use AI coding tools as a natural part of software development and know how to review AI‑assisted code with the same care as any other contribution

High Impact. Great People. Real Growth.

You’ll join a company with strong momentum, modern technology, and a collaborative culture where ideas and initiatives are encouraged.

At Voyado, we care about creating an environment where people can grow, collaborate, and enjoy the journey together. We move quickly, challenge ideas, and work closely across teams to deliver meaningful impact.

Some Of Our Benefits

• 30 days of vacation
• Wellness allowance
• Personal development opportunities
• Summits and team activities
• Four days from the office and one day from home

Making it personal with AI

We believe you’ll position yourself best for success in the interview process by being yourself, with support from AI where it makes sense. Later in the process, you may even be expected to use AI. At the end of the day, what matters is meeting you — the person behind the application.
