- Company: Paystack
- Location: Nigeria (Hybrid)
- Job type: Full-time
About the role
Paystack is a technology company helping merchants in Africa get paid globally. As a Senior Platform Security Engineer, you will take full ownership of the security architecture for Paystack’s shared cloud platform. This is not an oversight role; you will act as the engineering layer that makes the platform trustworthy by design. You will set the technical direction for platform security, make architectural decisions with company-wide reach, and build the function from the ground up. Your work will directly impact the security of all engineering teams, Paystack’s customers, and its regulatory standing across multiple markets.
Responsibilities
- Own and evolve the security architecture and organization-wide controls across Paystack’s multi-account AWS environment.
- Build production-quality tooling and automation to solve recurring cloud security problems.
- Design scalable identity and access-management systems, including secure self-service access requests for engineering teams.
- Set technical direction and standards for Platform Security to make secure practices straightforward for engineers.
- Translate regulatory and compliance requirements into practical infrastructure controls and automated audit evidence.
- Partner with DevOps and engineering teams to integrate security into infrastructure decisions from the outset.
- Strengthen security across secrets management, network controls, containers, and the infrastructure supply chain.
- Ensure security logs are reliably generated, structured, and delivered to the Security Operations team.
- Establish secure-by-default cloud standards and build automated controls to help teams meet them.
- Anticipate emerging platform risks and evolve controls as Paystack’s products and markets grow.
Requirements
- Ability to write high-quality, defensive code and build security infrastructure, automation, and tooling.
- Broad experience across Platform Security, including IAM, secrets, networks, containers, and software supply chains.
- Deep, hands-on experience securing AWS environments at scale, including multi-account architecture and access governance.
- End-to-end understanding of web security and the ability to connect application-level risks with cloud infrastructure failure modes.
- Experience operating in regulated environments and automating security controls across multiple compliance frameworks.
- Ability to design access-control systems that remain secure and manageable as the company grows.
- High agency, calm under pressure, and a track record of building scalable systems.
- Strong communication skills to act as a credible partner to engineers, identifying risks early and driving issues to resolution.
- Experience improving complex, live systems without unnecessary disruption.
Bonus points:
- Experience working within a parent-company security program while owning a regional environment.
- History of building security standards that engineering teams genuinely adopted.
- Understanding of the regulatory and data-protection landscape across Paystack’s markets.
- Experience establishing or shaping a Platform Security function.
- Ownership of infrastructure during security incidents.
