Security at Primer

As we continue to scale, we’re looking for an experienced Senior Engineering Manager to lead the next evolution of our security function, taking us beyond foundational protections and into mature, enterprise-grade resilience. You’ll take ownership of security engineering while helping shape broader business risk, privacy, and IT management strategies across a fast-paced, regulated environment.

🔍 What will the role involve?

• Defining and executing a long-term security strategy that goes beyond foundational protections, targeting enterprise-grade resilience.

• Leading and growing a high-impact security engineering team, embedding security into engineering, product and infrastructure at scale.

• Owning end-to-end vendor and workforce security processes, including onboarding, offboarding, and software procurement.

• Collaborating across teams to manage risks related to data privacy, regulatory compliance (e.g. GDPR), and IT operations.

• Driving readiness for security certifications such as future ISO 27001 compliance, as well as maintaining existing frameworks (SOC 2, PCI DSS, GDPR etc.)

• Acting as the key decision-maker for infrastructure security tooling and cloud security practices, ideally with deep AWS experience.

👀 What are we looking for?

• Proven leadership in scaling security functions within fast-growing, regulated industries

• Ideally experience or understanding of payments or eCommerce.

• Comfortable navigating ambiguity and change, managing stakeholders inc. c-suite.

• Hands-on experience with modern security standards and frameworks (SOC 2, PCI DSS, GDPR), with foresight into ISO 27001 readiness.

• A background in IT security management, with the ability to own workforce, device, and vendor risk processes.

• Strong grasp of cloud infrastructure security (preferably AWS) and how to operationalise it in production environments.

• Strategic mindset with the ability to elevate a security team from great to world-class

• Experience hiring and growing teams a must.

What’s the culture like at Primer?

We’re building a culture where people can come and do their best work and enjoy it. We want our people to be proud of the impact that they have at Primer, and of the work that they are doing. You will be working with a team of people who are mission-driven, smart, and reflective, and who are invested in building exceptional products and delivering success for our merchants (and we also know how to have fun along the way).

We work remotely. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships with each other through great remote working practices and thoughtfully designed face-to-face time together.

Finally, let’s go ahead and say it. The work that we do is challenging. Startups are a challenge, building category defining products is a challenge. You should be prepared for a challenge at Primer. But, there’s a big difference between a challenge and a struggle. The key difference is that the right challenge comes with the right support structures, an acceptance that not everything always goes to plan, a collaborative environment, and a great team around you. It’s never a challenge that you will face alone.
