While each business retains its own identity, culture, and technical specialism, all are supported by a central group function that invests in people, systems, and long-term sustainable growth.
This role is central to the day-to-day success of Arbtech and contributes directly to operational performance and customer outcomes. As a Junior Full-Stack AI/ML Engineer, you will be responsible for building innovative AI and mobile solutions, supporting data pipelines, and automating operational processes to improve efficiency across the business.
This is a hands-on role suited to someone who thrives in a fast-paced technical environment and enjoys taking ownership, solving problems, and making a tangible impact.

- Develop cross-platform mobile applications using Flutter for iOS and Android
- Design and maintain scalable backend systems handling data pipelines and model inference
- Create intuitive front-end and mobile interfaces that make AI accessible
- Contribute to operational automation to improve processes and efficiency at HQ
- Work collaboratively with internal teams and stakeholders
- Contribute to continuous improvement, compliance, and quality standards
Who you are

- 2–4 years of experience building and shipping full-stack applications
- Strong Python skills with experience in AI/ML libraries (PyTorch, TensorFlow, etc.)
- Experience with Flutter and Dart, including widgets, state management, and navigation
- Exposure to modern frontend frameworks (React/Next.js or similar)
- Basic knowledge of cloud deployment (Docker, CI/CD, AWS/GCP)
- Interest in LLMs, model deployment, or data pipelines
You are also:
- Comfortable working independently while taking initiative
- Curious and eager to grow across the full stack
- Able to debug and troubleshoot across the front-end, backend, and infrastructure
- Proactive in seeking feedback and finding ways to add value
Bonus points
- Flutter apps you’ve built and published
- Mobile app integration with backend APIs and cloud services
- App Store or Google Play deployment experience
- AI/ML tools or applications you’ve shipped or contributed to
- UI/UX design skills or open-source contributions
- Experience with Firebase, database design, API development, or responsive design
You’ll be joining a business where your contribution matters and where professionalism, integrity, and teamwork are genuinely valued. As part of the wider Celnor Group, you’ll benefit from group-wide investment, shared expertise, and opportunities to develop your career as the organisation continues to grow.
