Lead the evolution of tails.com’s AWS platform - design scalable, secure, resilient systems & turn complexity into clear, modern patterns.

Changing the world of pet food for good

Build our brand

Sound like a team you want to join? Here’s how you’ll make a difference:

We want to reshape our cloud platform so it is intentionally designed for where the business is heading - scalable, resilient, secure, and cost-effective by design rather than by accumulation. This is where you come in.

As a Senior DevOps Engineer, you will help lead that evolution from within the platform. You will take a critical, system-level view of our AWS environment, its architecture, deployment model, resilience patterns, observability, security guardrails, and cost structure, and help define what good looks like for the next phase of tails.com.

This is not about incremental patching or maintaining the status quo. It is about applying sound engineering judgement to decide what should be retained, what should be simplified, and what should be redesigned. You will help turn accumulated complexity into clear, repeatable platform patterns that enable engineering teams to move quickly and safely.

You will work closely with our engineering teams to ensure services are designed for operability and scale from the outset, and with the tails.com security function to embed secure-by-default principles and strengthen resilience and detection capabilities across the platform.

This role is suited to a senior engineer who enjoys reducing systemic complexity, shaping architecture through influence rather than authority, and remaining hands-on while improving the foundations beneath a growing product organisation.
