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.\nOver 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.\nAt 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.\nAbout the Senior Platform Security Engineer role\nEvery 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.\nThe 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.\nYou 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.\nWe’ll trust you to\nOwn and evolve the security architecture and organisation-wide controls across Paystack’s multi-account AWS environment.\n\nDesign scalable identity and access-management systems, including secure, self-service ways for engineering teams to request and manage access.\n\nEstablish secure-by-default cloud standards and build automated controls that help engineering teams meet them.\n\nPartner closely with DevOps and engineering teams, bringing security into infrastructure decisions from the outset.\n\nStrengthen security across secrets management, network controls, containers and the infrastructure supply chain.\n\nEnsure security logs and signals are reliably generated, structured and delivered to the Security Operations team.\n\nTranslate regulatory and compliance requirements into practical infrastructure controls and automated audit evidence.\n\nBuild production-quality tooling and automation that solve recurring cloud security problems.\n\nAnticipate emerging platform risks and evolve Paystack’s controls as its products, markets and infrastructure grow.\n\nSet the technical direction and standards for Platform Security, making secure practices straightforward for engineering teams to adopt.nditions, not just the ones you can see today\n\nYou’ll thrive in this role if you\nHave deep, hands-on experience securing AWS environments at scale, including multi-account architecture, organisation-wide policies and access governance.\n\nCan design access-control systems that remain secure and manageable as a company grows.\n\nWrite high-quality, defensive code and build security infrastructure, automation and tooling yourself.\n\nBring breadth across Platform Security, including IAM, secrets, networks, containers, infrastructure and software supply chains.\n\nUnderstand web security end to end and can connect application-level risks with cloud infrastructure failure modes.\n\nHave improved complex, live systems without unnecessarily disrupting what already works.\n\nHave operated in regulated environments and automated security controls and audit evidence across multiple compliance frameworks.\n\nAre a credible, practical partner to engineers: you identify risks early, communicate clearly, challenge decisions constructively and drive issues through to resolution.\n\nWork with high agency, remain calm under pressure and build scalable systems that outlast your direct involvement.\n\nBonus points if you\nHave helped establish or shape a Platform Security function.\n\nUnderstand the regulatory and data-protection landscape across Paystack’s markets.\n\nHave worked within a parent-company security programme while independently owning a regional or subsidiary environment.\n\nHave owned the infrastructure during security incidents.\n\nHave built security standards and reference architectures that engineering teams genuinely adopted.\n\nBenefits\nCompetitive compensation package and benefits\n\n13th month bonus\n\nTSG Equity compensation\n\nFull medical coverage\n\nWellbeing stipend\n\nHybrid working environment\n\nSmart, kind colleagues who are invested in your growth.\n\nPaystack is an equal opportunity employer and prohibits discrimination and harassment of any kind.

Our employment philosophy is to hire the best people and empower them to do the best work of their lives.
