Staff Engineer (Android) (Hiring Immediately)

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.

About the role

Our mission is to decouple payments from hardware by building a flexible, software-first payments platform that works across apps, devices, and partners.

As an Android Staff Engineer, you will operate at the platform level, working horizontally across multiple teams and domains to define and evolve the technical foundations of Dojo’s in-person payments ecosystem. This role is central to ensuring that Android technology across Dojo is coherent, secure, scalable, and built for long-term growth.

You will work across:

• Dojo Pay App: Customer-facing payment experiences

• Device OS: The software platform that runs on all Dojo devices, including launchers, SDKs and low-level Android system capabilities

• Device Management: Provisioning, updates, fleet management, and observability

• Payment Engine: Core payment acceptance SDKs and libraries

• Integration Platform: Partner and third-party integrations consuming Dojo’s Android capabilities

This is a senior technical leadership role for an engineer who thrives on complex systems, cross-team influence, and building platforms used by many teams and partners.

What you will do

• Provide technical leadership across Android domains, ensuring architectural alignment between apps, OS-level components, SDKs, and partner integrations.

• Define and evolve shared Android platform foundations including APIs, SDKs, libraries, patterns, and tooling used across Dojo Pay App, Device OS, Device Management, Payment Engine, and Integration Platform.

• Lead the design of secure, resilient, and scalable Android payment capabilities, from system services to developer-facing SDKs.

• Drive cross-cutting initiatives spanning multiple teams, such as security hardening, resilience, performance, observability, and compliance.

• Partner closely with backend, hardware, product, and security teams to deliver cohesive end-to-end payment solutions.

• Act as a technical authority for Android, setting standards for architecture, quality, documentation, testing, and release processes.

• Mentor senior engineers and tech leads, raising the bar for Android engineering across the organisation.

• Influence long-term platform strategy, identifying risks, reducing technical debt, and enabling faster, safer product development.

What you will bring

• Deep expertise in Android and Kotlin, with experience spanning applications, libraries, SDKs, and system-level components.

• Proven track record of staff-level impact, influencing architecture and direction across multiple teams or products.

• Strong experience designing and maintaining Android platforms or SDKs consumed by internal teams and external partners.

• Solid understanding of modern Android architecture including modularisation, Clean Architecture, Coroutines, dependency injection, and build tooling.

• Experience in payments, fintech, security, or other regulated domains, with a strong grasp of secure software design, or experience

• Ability to lead through technical influence rather than authority, navigating ambiguity and aligning diverse stakeholders.

• A platform mindset, balancing short-term delivery with long-term sustainability and developer experience.

• Passion for building mission-critical, high-reliability systems used at scale.

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.
