Principal Architect London / WFH
to £130k
Do you have an in-depth knowledge of secure system development?
You could be progressing your career in a senior, hands-on role at a successful and expanding Cyber Security software house that provide encryption and information security products to a range of finance, government, defence, law enforcement, and pharmaceutical companies.
About the Role
As a Principal Architect in a senior individual contributor role within a secure technology environment, you'll help shape the architecture of hardened Linux endpoints and Cross Domain solutions.
You'll work closely with the CTO, engineering, product, security, and customer-facing teams, providing technical leadership across multiple product lines. There's no large team to manage; instead, you'll influence through technical expertise, sound judgement, and the ability to make complex decisions.
Your Role
- Define the architecture and technical direction for new products and major initiatives
- Make complex architectural decisions and navigate technical trade-offs
- Embed security, assurance, and maintainability into product design
- Provide architectural input into complex customer deployments and integrations
- Identify opportunities for shared platforms, services, and tooling
- Act as a technical escalation point for challenging engineering and customer issues
- Develop architectural capability across the senior engineering community
- Be hands-on with complex systems, investigating problems and working alongside engineers to find the right solution
