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
- Node.js, event-driven architecture, React, TypeScript
- 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
