Lead the evolution of tails.com’s AWS platform - design scalable, secure, resilient systems & turn complexity into clear, modern patterns.
Who are we?
Hi, we’re Tails.com – we turn good days into great years for dogs and their humans.
We're working towards longer lives for millions of healthy, happy dogs by providing tailored nutrition that adapts to each dog’s unique needs. It all starts with a few simple questions about their age, breed, zoomie level, and tastebuds. From there, owners can create a personalised meal plan that's delivered to their door every month. No guesswork, no overwhelm. Just exactly the right care for every dog, every day. It's pretty clever stuff.
As a certified B Corp, being a responsible business is built into how we work – upholding high social and environmental standards to create better walkies for generations to come.
Now, we’re cooking up big plans. Having created an entirely new category in dog food, we have the backing of Purina – one of the world’s largest pet food companies. You’ll join a bunch of smart people working towards these same goals (and a bunch of very smart office dogs, all working on their own thing).
Job Title
Senior DevOps Engineer
Reporting of the role
Cloud Infrastructure Manager
Build our brand
We’re building an international brand, fast. We set ambitious goals. We challenge and support each other in equal measure. At the pace we’re moving, we prefer to test ideas and learn quickly rather than spend months building a business case. That means we celebrate when things go right, and we learn when things go wrong.
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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
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.
