Job Title: Security Engineer

Salary: £110K – £200K + Offers Equity

Company Description: Incident.io - Series B AI incident response platform backed by Index Ventures and Insight Partners.

Job Description:
Join Incident.io as our first Security Engineer to lead application security for a 60+ person product team. You will partner with engineers to design secure systems from the ground up, identifying vulnerabilities through white-box and black-box testing. This foundational role shapes the security culture at a rapidly scaling, high-trust engineering organization.

Location: London, UK

Why this role is remarkable:

• Foundational hire opportunity to build the security function from scratch without inheriting tech debt or rigid legacy processes.

• Join a high-growth Series B startup that has raised $100M from world-class investors like Index Ventures and Insight Partners.

• Work within a high-trust, ex-Monzo leadership culture that prioritizes shipping quality product daily and values engineering excellence.

What you will do:

• Partner directly with product teams to design and review features with security deeply integrated from the initial architecture phase.

• Identify and mitigate vulnerabilities using a mix of code reviews, architecture analysis, penetration testing, and automated fuzzing techniques.

• Implement pragmatic security tooling and automation across the CI/CD pipeline and GCP infrastructure to strengthen defenses without slowing delivery.

The ideal candidate:

• Senior or Staff-level professional with a deep track record in application security, vulnerability research, or specialized red teaming.

• Hands-on experience with modern web stacks, specifically Go, TypeScript, React, and cloud security within Google Cloud Platform (GCP).

• Collaborative mindset that thrives when embedded in product teams, acting as a coach rather than a gatekeeper for secure coding practices.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
