Job description

Role overview

A senior platform engineer is needed to shape the core infrastructure and developer experience for a real-money prediction and trading platform that lets users invest in outcomes across sports, entertainment, and political events. The role blends deep hands-on engineering with systems thinking, owning complex features from ideation through production while partnering with engineering leads to balance rapid innovation with stability and security. A defining element of the position is pioneering AI-augmented development, using coding assistants as true collaborators rather than experimental tools.

Responsibilities

• Establish team standards for AI-augmented development, including prompt engineering and validation frameworks that raise velocity without compromising code quality.
• Review AI-generated output for security gaps, over-abstraction, or architectural weaknesses, and contribute to team productivity metrics.
• Design, build, and maintain highly available cloud-native infrastructure that scales reliably with a growing user base.
• Build and optimize CI/CD pipelines and developer tooling to streamline the software delivery lifecycle.
• Implement platform security safeguards and compliance standards, and advance observability through monitoring, tracing, and alerting.
• Translate technical requirements into scalable platform solutions in partnership with product and engineering teams, mentor junior and mid-level engineers, lead incident response, and advocate for modern engineering practices.

Requirements

• Five or more years in platform engineering, DevOps, or backend roles, with a track record of scalable cloud-native environments on AWS and Kubernetes.
• Demonstrated proficiency using AI coding collaborators such as Claude Code, Cursor, or "GitHub Copilot" to ship production-grade code.
• Ability to evaluate AI-generated code for security and architectural issues and apply rigorous testing strategies.
• Strong hands-on experience with infrastructure-as-code frameworks such as Terraform, Pulumi, or CloudFormation.
• High proficiency in Java and Python; comfort bridging infrastructure and application logic, with Golang as a plus.
• Experience building mature CI/CD pipelines and working with observability tools such as Prometheus, Grafana, or Datadog.
• Proven ownership of complex projects in fast-paced environments, with strong communication skills for collaborating across distributed teams.

Nice to have

• Background in high-growth startup environments.
• Familiarity with financial systems, real-money transactions, or regulatory compliance.
• Experience building internal developer tools or CLI applications.
• Prior leadership of small project groups or squads within a larger team.

Benefits and work setup

• Fully remote position based in the United Kingdom.
• Home office setup stipend may be available for remote employees.
• Visa sponsorship is not available for this role.
