Summary Generated by Built In

We’re reinventing payments. In less than four years, Dojo disrupted the market to become the largest and most loved acquirer in the UK. Our payments infrastructure, purpose-built for in-person commerce, is game changing.

 

Now, over 150,000 customers across four countries choose to transact billions with us every year. But we’re just getting started.

 

Our people are the driving force behind our success. They are our greatest investment and our ultimate competitive advantage. We hire exceptional people and give them the autonomy, trust, and ownership to thrive. The results take care of themselves.

The role

 

At Dojo, we are building the next generation of reliable, secure payment infrastructure. We are looking for an experienced Platform Engineer to take technical ownership of the core foundations powering our products. In this role, you will design and evolve scalable cloud platforms that empower engineering teams to build, deploy, and operate services with greater speed and confidence.

 

As a senior individual contributor within our Core Infrastructure team, you will lead high-impact initiatives from discovery through to production, translate complex requirements into simple self-service capabilities, and make architectural decisions that deliver lasting value.

 

What you will do...

 

  • Own major platform initiatives end to end, making pragmatic architectural decisions and delivering measurable outcomes across core infrastructure.
  • Design, build, and operate reusable cloud capabilities across compute, networking, identity, and data, elevating standards for reliability, security, and observability.
  • Create secure self-service patterns and clear platform interfaces that reduce operational overhead and empower developer teams.
  • Lead workload modernisations and migrations onto supported cloud platforms, driving consistency, scalability, and efficiency.
  • Partner cross-functionally with engineering and security teams to establish guardrails, drive adoption, and mentor engineers.
  • Participate in a compensated on-call rotation, resolving complex technical challenges and turning incident learnings into better automation and resilience.

 

What you will bring...

 

  • Proven production experience designing, operating, and taking technical ownership of scalable cloud-native platforms.
  • Deep cloud-native expertise in Kubernetes, Infrastructure as Code (Terraform), and public cloud environments (GCP or AWS).
  • Strong software engineering skills in Go, C#, or TypeScript applied to production tooling, services, or automation.
  • Experience with GitOps, ArgoCD, and CI/CD pipelines, including automated policy guardrails and clear infrastructure APIs.
  • Solid knowledge of distributed systems and networking, including service mesh (Istio), edge technologies (Cloudflare), IAM, and observability.
  • Strong technical judgement and collaborative communication, with developer empathy and the ability to articulate trade-offs clearly to diverse audiences.

 

Dojo home and away

 

We believe our best work happens when we collaborate in-person. These “together days” foster communication, drive innovation and spark our brightest ideas.

 

That's why we have an office-first culture. This means working from the office 4+ days per week.

 

With offices across Europe, we know a thing or two about staying dynamic. Need deep focus? Head to a quiet zone. Big ideas? Collaboration spaces have you covered. Just here for a catch-up? Our social hubs make it easy. Do work that counts, in spaces made for you.

 

Question: what’s curious, relentless, and customer obsessed?

 

If you’re keen to know the answer, you’re a third of the way to meeting our Dojo values.

 

If the following speak to you, let’s talk:

 

You’re curious. You have a real desire to learn and create.

 

You’re relentless. You keep going even when it’s easier not to. 

 

You’re customer-obsessed. You know how important customers are to what you do. 

 

Diversity, equity, and inclusion at Dojo

 

From local bakeries to well-known eateries, Dojo payments serve over 150,000 places across the UK.

 

And something that’s fundamental to creating relevant, innovative products at Dojo is to build teams to reflect the diversity of the businesses we serve.

 

Our drive to improve diversity, equity, and inclusion is closely linked to helping employees thrive and innovating for better customer experiences.

 

If you care about your work, you’re curious, and you think customer-first, you have a place at Dojo.

 

To make sure you’re the best you can be throughout the recruitment process, let us know if you need any extra adjustments to help you thrive.
