The Role

Are you ready to take your engineering career to the next level? We’re looking for a Senior Software Engineer to join our high-performing, cross-functional squad, where innovation meets impact. You’ll play a central role in building scalable, cloud-native systems using the latest in AI, automation, and modern architecture.

This is more than just a coding job—you’ll be deeply involved in product development, architectural decisions, and best-practice engineering culture. If you're passionate about writing clean, well-tested code and collaborating with talented peers, this is your opportunity to make a real difference.

What you will be doing:

• Code That Matters: Design, build, and maintain robust full-stack solutions across our platform using TypeScript, AWS, GraphQL, and more.
• Own the Stack: From frontend to backend to infrastructure, you’ll take full ownership of the code you write and the systems you build.
• Innovation First: Help us integrate AI and automation into our products, solving real-world problems in smarter ways.
• Collaborate & Learn: Engage in pair programming, code reviews, and technical discussions that drive engineering excellence.
• Build It Right: Apply a test-driven mindset with robust automated testing and CI/CD pipelines (GitHub Actions).
• Keep It Running: Ensure systems are secure, scalable, observable (hello, DataDog), and performant in production.

What we are looking for:

• Senior-Level Expertise: Proven experience as a Senior Engineer or multiple years in software engineering roles.
• Full-Stack Fluency: Deep understanding of JavaScript/TypeScript, Node.js, React, GraphQL, and AWS (EKS, Lambda, RDS).
• API & Data Mastery: Skilled in building resilient APIs (REST/GraphQL) and managing backend services & databases.
• TDD Enthusiast: Proficient with testing frameworks like Jest, Pact, and a strong belief in quality-first development.
• CI/CD Experience: You’ve shipped code using GitHub Actions (or similar), and you know how to keep the pipeline green.
• Observability & Reliability: Experience with monitoring and alerting tools like DataDog.
• Proactive Problem-Solver: You take initiative, work independently, and thrive on solving complex technical challenges.

Interview Process

We want our process to be fair and transparent, so it’s only right that we tell you what the various interview stages are:

Stage 1 - We'll do a screener call with our recruitment team, where you can learn a bit more about Collinson, our values and we can confirm what you’re looking for in a new role.

Stage 2 - We'll do a short call with the VP of Software Engineering for around 30 minutes, who will tell you more about the team, our projects and ask questions about your career history and suitability for the role.

Stage 3 - We'll ask you to do a tech test at home. It will take around an hour.

Stage 4 - This is final and main stage, where we’ll meet you for around 2 hours, and you’ll get to spend time with different members of the engineering team. We’ll talk through your technical test and ask questions about your solution, alongside more job-specific scenarios.

Collinson is an equal opportunity employer and welcomes differences in all their forms including: colour, race, ethnicity, gender identity, sexual orientation, neurodivergence, family status, age, individuals with disabilities and people from all backgrounds, cultures and experiences as we strongly believe this contributes to our on-going success.
