About Boxbar Tech
Boxbar Tech is an award-winning, high-growth technology company transforming the way drinks are served across stadiums, arenas, festivals, events and hospitality venues around the world.
Our automated self-service drinks technology helps our partners serve customers faster, reduce queues, improve drink quality and increase operational efficiency. Behind the physical hardware is a growing technology platform combining Android applications, cloud services, payment integrations, management software and real-time data.
We design, build, deploy and support our technology in live environments where performance and reliability genuinely matter.
As Boxbar continues to scale, we are looking for a Mid-Level Software Developer who enjoys solving real-world problems, working across a varied technology stack and taking ownership of features from initial design through to deployment.
The Opportunity
You will join a small, collaborative engineering team working across several products and technologies.
No two weeks will be the same. You could be developing new features for our Android kiosk application, building backend services, integrating a new payment provider or investigating an issue involving hardware, software and networking.
This is an excellent opportunity for a developer who enjoys broad technical challenges and wants the freedom to contribute ideas, influence technical decisions and see their work operating in major venues and events around the world.
You will work closely with colleagues across Engineering, Product, Operations and Client Success to turn commercial and operational requirements into reliable, maintainable software.
What You'll Be Doing
Your responsibilities will include:
Developing new features for our Android kiosk application
Building and maintaining backend services and REST APIs
Integrating third-party payment providers and external platforms
Working with cloud infrastructure and serverless technologies
Supporting integrations between software, payment devices and physical hardware
Investigating and resolving issues across applications, devices, hardware and networks
Improving application performance, stability and reliability
Contributing to architecture and technical design discussions
Writing clean, testable and maintainable code
Reviewing code and helping maintain high engineering standards
Supporting deployment, monitoring and continuous improvement
Working closely with Product and Operations teams to deliver new functionality
Taking ownership of features from initial concept through to production
What You'll Work On
Projects may include:
Android kiosk software
Cloud APIs and backend systems
AI-assisted data analysis and internal insight tools
Real-time data processing
Payment-provider integrations
Hardware and peripheral integrations
Remote device management
Internal operational tooling
Application performance and reliability improvements
About You
We are looking for someone who:
Enjoys learning and working with new technologies
Takes ownership and follows work through to completion
Approaches problems pragmatically
Writes clean, maintainable code
Is comfortable working independently while collaborating with a wider team
Communicates technical information clearly
Enjoys investigating complex problems rather than working within a narrow remit
Can balance speed of delivery with quality and reliability
Is comfortable in a fast-moving scale-up environment
Wants to contribute ideas rather than simply implement specifications
Essential Skills and Experience
You will have experience in most of the following:
Approximately three to five years of commercial software-development experience
Strong Java and/or Kotlin development skills
Commercial Android application development
Building or consuming REST APIs
Working with SQL databases
Git and collaborative source-control workflows
Object-oriented programming principles
Debugging complex software issues
Writing clear, structured and maintainable code
Managing your own workload and priorities
Communicating effectively with both technical and non-technical colleagues
You do not need to have experience with every technology listed. Strong software engineering fundamentals, curiosity, and a willingness to learn are more important than matching the entire stack.
Desirable Experience
Experience in any of the following would be beneficial:
AWS
Serverless development using AWS Lambda or API Gateway
PostgreSQL
Firebase
Docker
Linux
Python
Node.js
Networking fundamentals
Payment integrations
Bluetooth, USB or serial communications
Embedded systems or IoT devices
CI/CD pipelines
GitHub Actions
Applications interacting with physical hardware
Remote monitoring or device-management platforms
Our Current Technology Stack
Our current technology stack includes:
Kotlin and Java
Android
AWS
PostgreSQL
Firebase
Docker
REST APIs
GitHub Actions
The stack will continue to evolve as the business and our products grow.
