Senior Software EngineerEngineering & Tech·London·Hybrid

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.

With over 30 years of expertise and a presence in 170+ countries, we partner with industry giants to create smarter, more meaningful customer interactions. Our portfolio includes Priority Pass—the world’s leading airport experiences programme—as well as a suite of loyalty and benefits solutions trusted by hundreds of organisations worldwide.

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

What Collinson Offers:

• Flexible and hybrid working options

• Work from anywhere – 8 weeks a year

• Generous parental leave and family-friendly policies

• Career development, mentorship, and training

• A supportive, inclusive culture with employee resource groups and diversity initiatives.
