The posting

Hacksaw Studios is looking for a highly experienced CTO / Lead Developer to join and lead our platform team. The platform team is responsible for building, maintaining, and continuously improving the core remote gaming server platform used across the group. This is a high-volume, transactional system operating in the online gaming industry, where scalability, security, reliability, and code quality are critical. This is a senior, hands-on technical leadership role. You will take ownership of the ongoing development and maintenance of the remote gaming server platform, as well as other platform-related services including API gateway solutions, back-office systems, integrations, and future unannounced projects. The role As CTO / Lead Developer for the platform team, you will be expected to combine strong technical leadership with hands-on development. You will work closely with the engineering team, senior management, and other departments to ensure that our platform continues to scale, perform, and meet the high standards required in a regulated industry. You will be responsible for driving technical decisions, improving architecture, reviewing and writing code, mentoring developers, and ensuring that the platform remains stable, secure, and maintainable as the business grows. A key part of the role will also be communication. You will need to clearly explain technical decisions, platform changes, risks, priorities, and ongoing work to both technical and non-technical stakeholders. This includes regular reporting to senior management, as well as close collaboration with departments such as Frontend, DevOps, Sysadmin, and Support to ensure they understand the platform, upcoming changes, operational impact, and how best to support the systems in production.

Requirements Extensive professional experience with C# and .NET Strong experience building scalable, production-grade backend systems Very strong SQL skills, including performance optimization and data modelling Understanding of caching principles in Redis or similar Experience working with transaction-based systems, ideally in online gaming, fintech, payments, trading, or similar industries Experience designing and operating horizontally scaled systems Strong understanding of system architecture, API design, reliability, and security Experience working with high-volume systems where uptime and correctness are critical A strong focus on code quality, testing, and maintainability Comfortable being hands-on and spending a significant amount of time coding Strong communication skills, with the ability to explain complex technical topics clearly to both technical and non-technical audiences Experience working across departments such as DevOps, infrastructure, support, product, or operations Ability to make pragmatic technical decisions in a fast-moving environment

Nice to have Experience from the online gaming or gambling industry Experience working in regulated environments Experience with remote gaming server platforms, payment systems, or other mission-critical transactional platforms Experience designing analytics systems for handling very large data sets for reporting purposes Experience leading engineering teams or acting as a technical owner for a major platform Experience with back-office systems, API gateways and integrations into third-party systems Experience reporting to or working directly with senior management

What we are looking for We are looking for someone who enjoys taking real technical ownership who is a strong, hands-on developer. You should be excited by complex backend systems, care deeply about quality, and be comfortable balancing long-term architecture with hands-on delivery. You should be able to lead from the front, contribute directly to the codebase, and help the team make good technical decisions while keeping the platform secure, scalable, and reliable. Just as importantly, you should be a strong communicator. The platform team works closely with DevOps, sysadmin, support, and senior management, and this role will be expected to create clarity across those teams. You should be comfortable explaining what the platform team is doing, why certain technical decisions are being made, what risks or priorities exist, and how other departments are affected. About Hacksaw Hacksaw is a fast-growing company in the online gaming industry, building products and platforms used by operators and players across multiple markets. We work in a highly regulated environment and place strong emphasis on quality, reliability, and responsible technical delivery. If you are an experienced C# developer and technical leader who wants to take ownership of a critical high-volume gaming platform, we would like to hear from you.

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
