CTO / Lead Developer - Platform Team

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.

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.

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.
