At Collinson, we shape the experiences behind some of the world’s most recognisable brands. From airlines and hotels to financial services leaders, our products power loyalty, travel, and customer engagement at global scale.

Now, we’re looking for a Senior Software Engineer to help us build what’s next.
The role
This isn’t a maintenance role. You’ll be working on greenfield, cloud-native products, shaping systems from the ground up alongside a cross-functional team of engineers, product managers, and designers.
You’ll own features end-to-end—from early design through to deployment and monitoring—while contributing to a culture that values clean code, strong engineering practices, and continuous improvement.
Expect to be hands-on every day: writing code, reviewing PRs, refining ideas, and solving meaningful technical challenges that directly impact global users.
What you’ll be doing
Designing and building scalable, secure, cloud-native applications using TypeScript (Node.js & React)
Owning complex features from concept to production
Collaborating closely with your squad to shape solutions and deliver high-quality software
Championing automated testing, CI/CD, and engineering best practices
Deploying and operating services in AWS using tools like Terraform, Kubernetes, and GitHub Actions
Driving improvements in observability and system reliability (DataDog)
Exploring and integrating AI-powered development tools and automation
Mentoring engineers and contributing to a strong, supportive engineering culture
Our tech environment
Frontend: React, TypeScript
Backend: Node.js, event-driven architecture
Cloud: AWS (plus exposure to Azure)
Infrastructure: Terraform, Kubernetes
CI/CD: GitHub Actions
Observability: DataDog
Ways of working: Agile, collaborative, high-trust
What you’ll bring
5+ years of experience building modern software, with strong TypeScript expertise
Solid understanding of JavaScript fundamentals and full-stack development
Experience designing and running production systems in the cloud
Confidence working with event-driven architectures
Strong grounding in TDD and automated testing practices
Experience building and maintaining CI/CD pipelines
A pragmatic, product-focused mindset—you solve problems, not just write code
Who you are:
You’re curious and always looking to improve how things work
You think creatively and bring fresh ideas to the table
You communicate clearly and collaborate effectively across teams
You care about the quality of your work—and it shows
You want to make a real impact, technically and operationally
