Senior Security Engineer (Product Security) (Hiring Immediately)

Anticipate attacks, outsmart threats and safeguard innovation.

Gallup is seeking a senior security engineer (product security) to help build and scale security into the core of our products. This role sits at the intersection of engineering and offensive security — ideal for someone who enjoys breaking things thoughtfully and then helping teams rebuild them stronger.

You’ll bring an attacker’s mindset to uncover real-world risks across our applications and then partner directly with senior, staff engineers and engineering managers to turn those findings into durable, secure solutions. This is a high-impact role with the autonomy to shape how security is embedded across Gallup technology.

What You’ll Do

• Perform penetration testing across web, mobile and API applications to identify and validate security vulnerabilities
• Partner with engineering teams to incorporate security into applications from the start through secure coding guidance.

What Makes You Stand Out

• Clear communication: You turn complex risks into clear, actionable guidance.
• Self-starter mindset: You thrive working independently while knowing when to pull in others.
• Impactful speed: You move quickly without cutting corners, ensuring durable results.
• Adaptive focus: You stay effective across shifting priorities and varied demands.
• Calm under pressure: In urgent incidents, you bring clarity and steadiness.
• Persistence and precision: You solve tough security challenges with practical, scalable solutions.

What You Need

• Bachelor’s degree in cybersecurity, information assurance, computer science or a related field required
• At least four years of experience in testing applications and contributing to improving their security required
• Demonstrated deep expertise in mobile, web and API penetration testing required
• Proven ability to partner with engineering teams to remediate vulnerabilities and improve secure development practices required
• Strong programming or scripting skills in at least one language (e.g., Python, JavaScript, C#, Java) required
• Participation in bug bounty programs or responsible disclosure is a plus
• Certifications such as OSCP, OSWE, GWAPT and GXPN are a plus
• A commitment to working on-site at Gallup’s London office at least three days per week required
• Eligibility to work in the United Kingdom; this position is not eligible for employment visa sponsorship
