Software & Application Security Lead

Permanent | Hybrid (UK - a few visits per month) | Up to £84,000

We're partnered with a modern, forward-thinking professional services firm that puts security at the heart of everything they build. As part of their growing technology function, they are looking for a Software & Application Security Lead to shape how security is embedded into every stage of their digital product journey.

This role has real influence – you will define the software security strategy, guide engineers on best practice, and ensure the products they deliver are secure by design. You will work closely with developers, architects, and business stakeholders to create an environment where secure coding and proactive risk management come naturally.

What you’ll be doing

You will lead the promotion of a security‑first culture across agile product teams, defining and delivering a clear application security strategy aligned with business goals. Working hand‑in‑hand with developers, you will weave security seamlessly into the software development life cycle – from designing controls and integrating testing into CI/CD pipelines to supporting vulnerability management and remediation. Acting as the go‑to expert for secure design, threat modelling, and compliance, you will enable teams to build securely from the start. You will also maintain clear documentation and provide regular updates to senior leaders, ensuring transparency and visibility across the organization’s overall security posture.

What we’re looking for

• A strong background in both software development and security, confident working with code and understanding risk.
• Proven experience embedding security in agile development environments.
• Hands‑on knowledge of cloud platforms, CI/CD pipelines, and scripting (PowerShell, YAML, JSON, etc.).
• Familiarity with frameworks and standards such as OWASP, NIST SSDF, ISO27001, or NCSC.
• Practical experience with threat modelling, security tooling, and risk assessments.
• Excellent communication skills, able to influence and engage at all levels from developers to executives.
• A collaborative, proactive approach to solving problems and improving security culture.

Why this role?

You’ll join a business that truly values security and invests in doing it properly – not as a box‑ticking exercise. You’ll have the freedom to shape how security fits into product development, the support of a talented engineering community, and the flexibility of a modern hybrid setup.

Location

London (hybrid – typically a few office visits each month)

Salary

Up to £84,000 + benefits
