Security Architect – Offensive Security
London | Manchester
Adeptis Group is recruiting a Security Architect with a strong offensive security background to join a leader in cyber security who focuses on proactive and innovative strategies to protect businesses, individuals and society from real-world threats. Their team is made up of highly skilled and creative professionals who bring diverse perspectives and deep expertise to their work. With a strong commitment to pushing the boundaries of the industry, they empower their people to drive their own growth and development both professionally and personally.
They are currently seeking an experienced Security Consultant with a strong foundation in architecture, design reviews, threat modelling and risk analysis. This role also values hands-on technical expertise, such as penetration testing and security assessments. The position involves working closely with a key client, providing tailored insights and strategic guidance to strengthen their security posture.
The ideal candidate will have a good grasp of networking, infrastructure, and application security - across both on-premises and cloud environments (e.g., AWS, SaaS). Experience with SDLC toolsets and infrastructure-as-code solutions will further enhance your ability to excel in this role. If you thrive in a fast-paced, high-impact environment, this opportunity offers a unique chance to advance your career.
Key Responsibilities:
You’ll be a critical part of the client’s security team, providing security-oriented perspectives on core design decisions. Key areas of focus will include:
Authentication & Authorisation: Advising on secure implementations, including technologies like OAuth and identity providers, while addressing common flaws and bypass techniques.
Data Security: Ensuring secure storage and transfer of sensitive data, balancing technical and architectural considerations.
Input Validation: Advocating for best practices, such as allow-lists over deny-lists, and offering guidance on specific language implementations.
Logging & Monitoring: Promoting robust logging practices for security-relevant activities and integrating logs into centralised sources like SIEMs.
Supply Chain Security: Evaluating third-party SaaS solutions and discussing key considerations such as tenancy models, authentication options, and platform testing.
Cloud Security: Leveraging knowledge of AWS, Azure, and other cloud platforms to ensure secure hosting of applications and workloads.
Emerging Technologies: Quickly adapting to new or niche technologies, identifying potential weaknesses, and providing hardening strategies.
Your expertise will help define and implement secure design patterns while developing standards where none exist.
Professional Development:
This role includes a balance of client-focused work and professional growth, with approximately 20% of your time allocated for:
* Training (both receiving and delivering)
* Research
* Service development
* Internal security assessments
Key requirements:
* Hands-on technical security expertise (e.g., penetration testing, security assessments)
* Experience working with large enterprise environments and global teams
* Familiarity with cloud platforms and infrastructure-as-code solutions
* Strong communication skills, with the ability to convey technical issues to non-technical stakeholders
* Certifications such as CREST CRT, Cyber Scheme Team Member, or OSCP
This is a hybrid role with flexibility to work remotely most of the time. Office locations are London and Manchester, where you’ll have opportunities to collaborate, train and socialise with a supportive and talented team.
