The posting

The Mill Adventure is a scale-up with the ultimate mission of building awesome products that will change the way the iGaming industry operates. We started our journey in 2019, with the vision of building a technology driven organisation and creating a fast moving team consisting of the best of the best specialists in their respective fields.

Today, we provide a complete gaming platform, for rapid deployment and success in iGaming. Our team of 100+ technology and iGaming experts is guided by passion for invention, operational excellence and commitment to improve the inefficient.

We trust and value our team and we strive to accommodate the right working conditions for each individual, in remote, office based or mixed models. We see the strength in being different and embrace the cultural diversity existing in our group.

One of our key strengths is the modern technology stack, which we think is exciting to work with and allows us to move fast. The event-driven architecture of domain-specific services, organized in monorepo with automated CI/CD pipelines, not to mention being natively serverless creates a unique development environment, that is a joy to work with. We want to stay lean and agile, without the overhead of artificial processes and a minimal number of meetings. We work closely, yet with a lot of autonomy.

As our gaming platform is a quite complex system, you will have an opportunity to get involved in a variety of different tasks. From integration with payment or game providers, preparing for new markets, introducing new features, and improving and optimizing existing ones. We have a lot of unique and interesting projects:

  • SmartLobbies (AI-powered, personalized game recommendations),
  • Tournaments (a flexible system supporting real-time competitions between players),
  • Automated withdrawals (rule-based component for automating critical processes),
  • Betpool (innovative social gaming solution).

If that sounds interesting, we are looking for a Senior Back End Developer to join us in our adventure.

The role includes the following responsibilities:

  • Develop and maintain our gaming platform, including customer-facing features, compliance and reporting systems, and core platform components
  • Review and debug code with attention to quality, data integrity, edge cases and unintended effects across the platform
  • Participate in software design and architecture discussions
  • Take ownership of changes throughout the software development life cycle, clarifying requirements, assessing impact and verifying behaviour after release
  • Collaborate with internal teams, vendors, and partners
  • Use AI-assisted development tools, scripting and automation to improve development and engineering workflows, critically evaluating outputs and remaining accountable for the quality of changes
  • Design and perform tests that verify business rules, data accuracy and failure scenarios, working with QA to ensure changes are adequately covered

Requirements

You'll be a great fit if you have:

  • Knowledge of JavaScript, TypeScript, and Node.js ecosystem
  • Previous experience working with AWS (or similar) solutions (DynamoDB, Kinesis, Lambda, Quicksight, S3, etc.)
  • Experience designing and maintaining automated unit and integration tests
  • An analytical and methodical approach to problem-solving, with a strong focus on the initiative to investigate unclear requirements and underlying causes
  • The ability to work independently
  • Self-management and communication skills
  • Proven experience as a Senior Software Engineer, working with Back-End
  • Experience with event-driven architectures
  • Experience developing highly available, fault-tolerant systems and maintaining data consistency in event-driven architectures
  • Practical experience using AI tools in software development, with the ability to critically review generated code and validate its behaviour; an interest in extending AI and automation into engineering workflows
  • Experience with compliance, regulatory reporting or other systems where data accuracy, traceability and auditability are essential would be an advantage

Our general expectations are:

  • High communication standards - participate in team chats, provide help when someone needs, ask for help when needed, participate in internal discussions and chats with stakeholders
  • Pro-activeness - plan your own work, seek for new tasks, participate in activities beyond primary tasks, eg. monitor alerts, help in questions from your area of expertise
  • Professionalism - provide high quality of work, seek and suggest improvements
  • Kindness - be good to others

Benefits

  • A lean, focused company, offering a flexible working environment
  • The opportunity to work with and learn form a highly skilled, talented team
  • A great company culture, where accountability is innate, transparency is key and competency is virtue
  • Being part of a small, tight knit, caring community
  • Work equipment of your choice
  • Private health insurance
  • Learning budget
  • Fitness benefit
  • Parking/transport or co-working allowance
  • Company wide and team based get togethers

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
