This is a new AppSec-focused addition to Security Engineering, working closely with product engineering teams across the SDLC. The role provides technical input as needed rather than end-to-end ownership.
We're currently hiring a Senior Application Security Engineer to own AppSec end-to-end across our development lifecycle: from design-stage threat modelling through to code review, tooling, and remediation of findings. This is a hands-on engineering role, not a compliance or customer-facing one.
What you’ll do:
- Own the AppSec programme for Flagstone and report back on its success to relevant stakeholders including leadership.
- Formalise a secure development lifecycle which includes owning threat modelling and secure design review for new features and systems.
- Run and continuously improve secure code review practices, including SAST/DAST/SCA tooling integrated into CI/CD pipelines.
- Coordinate external and execute internal penetration test engagements and drive remediation to closure with engineering teams.
- Maintain and evolve secure coding standards, and run a security champions programme to scale AppSec practice across engineering.
- Track and report on vulnerability management across the application estate.
- Contribute AppSec expertise to incident response where application-layer issues are involved.
- Manage application cyber risk according to the internal Flagstone Risk Framework.
What we’re looking for:
- 5+ years in application security or a security engineering role with a strong AppSec component.
- Practical experience embedding security in the SDLC.
- Hands-on experience with SAST/DAST/SCA tooling and CI/CD pipeline integration.
- Strong grasp of OWASP Top 10 and secure coding practices.
- Experience coordinating and running penetration testing programmes.
- Comfortable communicating security risk clearly to engineering and product audiences.
- Demonstrable experience with adversarial security testing.
- Great communication skills and stakeholder management.
- Strong critical thinking skills and a curiosity for learning new technologies and frameworks.
Nice to Have:
- A strong link to the AppSec community and industry.
- OSCP, CSSLP, or equivalent hands-on offensive/AppSec certification.
- Experience in a regulated financial services environment.
- Exposure to cloud-native application security.
How we reward you:
- Competitive bonus scheme.
- Flexible benefits budget.
- A range of salary sacrifice options.
- Around the World scheme - 3 months work from anywhere scheme.
- Mental wellbeing support.
- Learning and development - £1,000 personal development budget.
- Private health care.
- Medical cash plan.
- Life insurance and Income Protection.
- Matched pension contributions up to 5%.
- 25 days holiday - plus bank holidays, well-being days and volunteering days.
- Enhanced Parental Leave.
All are welcome. At Flagstone, we're assembling a diverse team that defies our industry's norms.
