Senior Software Engineer – Connected Data Platform

📍 Manchester - Hybrid x2 a week
🧠 CAPTG ¦ Greenfield Product

Build the platform that will power our business for the next decade.

We’re looking for a Senior Software Engineer to play a key role in building our Connected Data Platform – a greenfield, cloud‑native product that will sit at the heart of Cox Automotive Europe.

This platform will provide customers with a single view of all their assets across our ecosystem and will form the technical foundation of the business for the next 10+ years. If you enjoy solving complex problems, shaping technical direction, and working with modern cloud technologies, this is a role where you can make a genuine long‑term impact.

What you’ll be working on

As a Senior Software Engineer, you’ll be hands‑on in designing, building and evolving scalable software solutions while working closely with product, engineering and platform teams.

You’ll:

* Design and build high‑quality, cloud‑native solutions on AWS
* Write clean, well‑tested, maintainable code and champion engineering quality
* Contribute to technical design and help shape our future tech stack
* Work in a product‑led, Agile environment delivering real customer value
* Identify and resolve performance, scalability and security challenges
* Support and mentor other engineers through collaboration and code review
* Contribute to knowledge‑sharing across engineering and wider technology teams

This is a role where your voice matters — we actively encourage engineers to challenge the norm and improve how we build and deliver software.

Our tech stack (and why it’s exciting)

This is a true greenfield platform, so our stack is evolving — and you’ll help influence it.

Current core technologies include:

* AWS (cloud‑native, managed‑service first)
* .NET 7 on Linux, Docker, EKS / ECS
* Infrastructure as Code using Terraform
* Event‑driven architecture (Kafka / AWS MSK, SNS/SQS, EventBridge)
* SQL & NoSQL (Aurora, DynamoDB, DocumentDB)
* AWS Lambda (JavaScript / Python)
* React for web experience
* GitHub Enterprise & GitHub Actions for CI/CD

What we’re looking for

You don’t need to tick every box, but you’ll ideally bring:

* Strong experience as a Software Engineer working with .NET and AWS
* Experience building scalable systems using modern engineering practices
* A solid understanding of event‑driven architectures and cloud platforms
* Experience with Infrastructure as Code (Terraform or similar)
* A passion for clean code, testing (including TDD), and continuous improvement
* Confidence working with both technical and non‑technical stakeholders

Just as importantly, you’ll be curious, collaborative, and motivated to keep learning.

Why join us?

* A high‑impact greenfield product with long‑term strategic importance
* The chance to shape technical direction, not just follow it
* Modern engineering practices and cloud‑native tooling
* A culture that values quality, learning, and collaboration

Ready to help build what’s next?

If you’re a Senior Software Engineer who enjoys solving meaningful problems, shaping platforms, and working with modern cloud technology, we’d love to hear from you.
