Mast Jobs

Job title: Principle Security Engineer

Location: Leeds, UK

Overview of the role:

We have an exciting new role in our PokerStars Platform Security Architecture team for a Principle Security Engineer. You will support us during our strategic journey in the modernisation of our applications and platform.

You’ll be reporting into the Head of Platform Security Architecture in a team who all share a passion for our products and understanding of our customers behaviour.

You will work with our product, solution architects and engineering teams to ensure our new platforms, their integrations and the supporting AWS cloud infrastructure are secure by design and implemented to best practices. You will provide security expertise and technical thought leadership to a critical function who are building a new platform (Flutter Studios) to provide casino games as a capability across our group.

Our Leeds office is at the heart of our business. The 8-storey building has an onsite staff gym and cafeteria, two heated rooftop terraces, a dedicated gaming room and a staircase amphitheatre. The space brings all our teams under one roof in the biggest private letting office in Yorkshire. 

What you’ll do:

  • Work closely with our solution architects and engineers to provide expert security guidance and direction ensuring the platform components are built and consumed in adherence to industry security standards.

  • Be embedded in the Flutter Studios function of our company, acting as a single point of contact for all security matters.

  • Provide hands-on support in building security controls or contributing to secure configurations and features (e.g. cloud security policies, zero-trust authorisation mechanisms).

  • Help teams in a practical manner to identify and effectively treat risks within our environment, ensuring that ultimately our end players can trust us.

  • Work with other members of the wider Security Engineering team to ensure we have a consistent and measured approach to security.

What you’ll bring:

  • Experience protecting customer data in regulated production environments, ensuring compliance with both security best practices and regulatory requirements.

  • Extensive experience performing security analysis of cloud native architectures using a threat-based approach, implementation of defence in depth, and prioritisation of security controls.

  • Extensive experience in defining security controls for multi-tenancy platforms with various API driven integration points and data streaming services.

  • Real world technical “hands-on” experience deploying complex solutions and designing countermeasures to identified security risks.

  • Experience defining both data plane and control plane security controls for cloud environments ensuring there are no toxic combinations.

  • Experience defining and implementing modern authentication and authorisation models based on zero trust (ideally with exposure to token-based architecture and verification mechanisms).

  • Practical working experience and knowledge of workplace technology security solutions e.g., network, email, and endpoint security controls.

  • Knowledgeable in implementing controls to prevent exploitation of OWASP Top 10, CWE Top 25 vulnerabilities.

Your skills:

  • Ability to perform security assessments using threat modelling, playbooks, and security patterns to identify weaknesses and appropriate treatment of risks for associated threats.

  • Ability to identify toxic combinations of design weaknesses in both data and control planes and provide effective remedies.

  • Ability to provide security patterns, hardening and vulnerability remediation advice.

  • Ability to apply cybersecurity and privacy principles to organizational requirements (relevant to confidentiality, integrity, availability, authentication, non-repudiation).

  • Knowledgeable in applying and embedding security as part of the wider software development lifecycle (SDLC) process.

  • Understand the context of requested changes and ensure that implementation does not weaken the security posture.


  • Sound understanding and experience working with APIs, AWS, Kubernetes, Kafka, and mTLS.

  • Sound understanding of cybersecurity standards, methodologies, and frameworks.

  • Sound understanding of network access controls and identity and access management.

  • Versed in modern authentication and authorisation practices of zero-trust architectures.

  • In-depth knowledge of each security domain and how each domain relates to support a secure platform.

  • A keen interest in learning innovative technologies and a passion for information security.

  • Be able to work with multiple teams across the business with differing priorities.

  • Be able to drive initiatives & operate autonomously with support where needed with limited supervision.

  • Apply a pragmatic and balanced approach to security risk against delivery timelines and business objectives.
