Paystack’s mission is to power African ambition. Over 300K businesses across Nigeria, South Africa, Ghana, and Kenya use Paystack’s modern payments gateway, including Qatar Airways, MTN, Burger King, UPS, Africa World Airlines, AXA Mansard Insurance, FairMoney, PiggyVest, Crocs, Under Armour, Richemont Lifestyle Group, and many others.
Over the last 10 years, we’ve built products that have helped shape online payments in Africa, from automated recurring payments to direct bank payments and automated chargebacks. Today, Paystack is part of The Stack Group (TSG), a family of technology brands building modern infrastructure across payments, banking, consumer products, and emerging technologies.
At Paystack, we hire talented people, treat them with genuine respect, and give them the space, resources, and support to do the best work of their lives. We’d love your help.
Every engineering team at Paystack builds on a shared cloud platform. If that platform is not secure, nothing built on top of it is secure. This role owns that foundation - not as an oversight function or as a policy team but as the engineering layer that makes the platform trustworthy by design.
The decisions made here are not team-level decisions. You will own Paystack's AWS organisation end-to-end: its architecture, its account structure, and the organisation-wide controls that govern how every team operates within it. The guardrails you set, the permission model you design, and the security primitives you build are what all engineering teams depend on to do their own work effectively. You are upstream of all of them, and what you build has direct consequences for Paystack's customers, merchants, and regulatory standing across multiple markets.
You will inherit a functioning platform and take full ownership of it - improving what exists, completing what was started, and defining what comes next. This is not a role where someone hands you a roadmap. You will identify what needs to be solved before it is articulated, set the technical direction for how platform security works at Paystack, and make architectural decisions with company-wide reach. You will also build the Platform Security function - shaping what it looks like, how it operates, and who it eventually comprises.
Own and evolve the security architecture and organisation-wide controls across Paystack’s multi-account AWS environment.
Design scalable identity and access-management systems, including secure, self-service ways for engineering teams to request and manage access.
Establish secure-by-default cloud standards and build automated controls that help engineering teams meet them.
Partner closely with DevOps and engineering teams, bringing security into infrastructure decisions from the outset.
Strengthen security across secrets management, network controls, containers and the infrastructure supply chain.
Ensure security logs and signals are reliably generated, structured and delivered to the Security Operations team.
Translate regulatory and compliance requirements into practical infrastructure controls and automated audit evidence.
Build production-quality tooling and automation that solve recurring cloud security problems.
Anticipate emerging platform risks and evolve Paystack’s controls as its products, markets and infrastructure grow.
