### About the role and team:

### Senior Backend Engineer

### Build software that matters. Shape the future of engineering.

We're looking for an experienced Senior Backend Engineer who is passionate about building scalable, high-quality software and helping teams grow. This is more than a hands-on engineering role—you'll influence technical direction, mentor other engineers, drive architectural decisions, and help us embed AI and automation into the way we deliver value for our clients.

You'll thrive here if you enjoy solving complex problems, challenging assumptions, collaborating openly, and taking pride in delivering software that makes a real business impact.

### What You'll Do

### As a Senior Backend Engineer, you will:

- Design, build and maintain scalable, secure and resilient backend systems using Kotlin and Spring Boot

- Lead technical design and architectural discussions, ensuring solutions are maintainable, performant and aligned with best practices.

- Develop and evolve RESTful APIs with a focus on security, versioning, performance and reliability.

- Champion engineering excellence through clean code, automated testing, documentation and code reviews.

- Drive delivery across multiple initiatives while balancing speed, quality and commercial value.

- Mentor engineers through coaching, pairing and constructive feedback, helping raise capability across the team.

- Collaborate with cross-functional teams to solve problems together and deliver outstanding outcomes for clients.

- Research and evaluate emerging technologies, frameworks and AI capabilities that improve how we build software.

- Promote automation wherever possible, removing repetitive work so teams can focus on solving meaningful problems.

- Contribute to a culture of continuous learning, innovation and technical excellence.

### What You'll Bring

### Technical Expertise

### You'll have strong commercial experience with:

- Spring Boot and the wider Spring ecosystem

- Spring Data JPA / Hibernate

- Spring Security including OAuth2 and JWT

- REST API design and implementation

- Microservices and distributed system design

- SQL databases with strong query optimisation skills

- NoSQL databases

- Messaging technologies such as Kafka or RabbitMQ

- Docker and containerised application development

- Cloud platforms (AWS, Azure or GCP)

- CI/CD pipelines using tools such as Jenkins or GitLab CI

- Git and modern software development workflows

- Observability tooling including logging, metrics and distributed tracing

- Comprehensive testing across unit, integration and functional layers

- Maven or Gradle

- Java concurrency and JVM performance fundamentals

### What Success Looks Like

### You'll demonstrate:

### Technical Excellence & Craft Mastery

- Write clean, maintainable and highly optimised code.

- Set high standards for quality, testing and documentation.

- Coach others in engineering best practices and modern development techniques.

### Architectural Leadership

- Design scalable, resilient and secure systems.

- Make thoughtful architectural decisions that support long-term maintainability.

- Evaluate new technologies and guide adoption where they add value.

### Commercial Delivery

- Lead projects from discovery through delivery.

- Understand client challenges and translate them into practical technical solutions.

- Deliver outcomes that create measurable business value.

### Leadership & Collaboration

- Lead engineering ceremonies and facilitate productive technical discussions.

- Mentor and develop engineers across the team.

- Communicate effectively with both technical and non-technical stakeholders.

- Foster an environment where knowledge sharing and continuous improvement are part of everyday work.

### AI & Innovation

- Explore and implement AI-driven approaches that improve engineering efficiency.

- Champion responsible adoption of AI across delivery teams.

- Help shape our engineering practices for the future.

### What we’ll offer you:

We trust people to do their best work. That means flexibility over rigid rules, impact over activity, and real investment in your growth both professionally and personally. You’ll be part of a supportive, and friendly culture, surrounded by smart, curious people who care deeply about what they do.

We offer flexible working, including hybrid and remote options. Our office hubs are located in Edinburgh, Leeds, Manchester, London and Bulgaria, with occasional travel to client sites or CreateFuture offices when needed.

We trust you to manage your time balancing collaboration with client time and focused work. What matters is the impact you have, not how busy you look.

### Our hiring process

We try to keep our hiring process clear, fair and respectful of your time. We aim to get back to everyone who applies and we will be upfront about where you are in the process.

### It usually looks like this:

- Call with our Talent Acquisition Team

- Role specific capability interview

Depending on the role, we might also ask you to do a short presentation, a practical or technical task or have a values focused conversation. We will explain what is involved before anything happens.

### Inclusion at CreateFuture

We believe diverse teams build better workplaces and better products. We want CreateFuture to be a place where people feel able to be themselves and do their best work.

If you need any adjustments or support during the application process, just. We will do what we can to help.

We look forward to your application!

**Live in Xdesign’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
