Job description

Overview

Join to apply for the Software Engineer .NET role at Dojo

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. 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 As a Software Engineer in the Data Products team, you will play a key role in shaping how we transform Dojo’s payments data into valuable insights for our merchants. You’ll contribute to building scalable data products and APIs that enable small businesses to understand their performance, benchmark against peers, and unlock new opportunities for growth. You will actively participate in Agile ceremonies such as daily stand-ups, sprint planning, and retrospectives, collaborating closely with product managers, analysts, and engineers across the business. Our team is at the heart of Dojo’s mission to help merchants thrive by providing intelligent, data-driven insights through accessible and impactful products. This is a unique opportunity to work on greenfield initiatives, designing systems that scale with millions of transactions while using modern technologies and best practices.

What You Will Do

• Design, develop, and maintain scalable backend services and APIs using .NET.
• Build and optimise data models (SQL/NoSQL) to process and serve high-volume payments data.
• Work closely with product managers and data analysts to turn raw data into actionable insights.
• Implement reliable data pipelines and integrations that ensure merchants receive accurate, timely, and meaningful analytics.
• Write clean, maintainable, and well-documented code with a strong focus on testing and observability.
• Collaborate with other engineers through code reviews, technical discussions, and knowledge-sharing sessions.
• Contribute to architectural decisions to ensure our systems are scalable, secure, and future-proof.

What You Will Bring

• Solid experience with .NET for building APIs and backend services.
• Strong understanding of data modelling and performance tuning (SQL/NoSQL, ideally MongoDB).
• Knowledge of data pipelines, event-driven systems, or batch processing.
• Familiarity with best practices in software development (CI/CD, automated testing, version control).
• Good communication skills and the ability to collaborate in cross-functional teams.
• Passion for solving problems with data and building products that help customers grow.

Nice to have

• Experience with frontend frameworks like React (or willingness to learn).
• Exposure to cloud platforms (e.g. Google Cloud Platform, AWS, or Azure).
• Familiarity with Kafka, gRPC, or other streaming/event-driven architectures.
• Knowledge of data analytics tools or business intelligence platforms.
• Experience with Infrastructure as Code (Terraform, Pulumi).
• Exposure to machine learning workflows or building highly efficient, scalable data processing pipelines.

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. 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. Building teams to reflect the diversity of the businesses we serve is fundamental to creating relevant, innovative products. 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.
