About the Senior IT Engineer role

  • Our IT Operations team is a small, high-impact platform engineering unit.
  • We manage the identity, endpoint, network, and access infrastructure for over 300 employees and 100+ outsourced agents across six offices (Lagos, Nairobi, Accra, Cape Town, and Dubai).
  • We manage a fully automated macOS fleet, every physical office network, and roughly thirty core applications secured behind SSO.
  • We do all of this inside a highly regulated fintech environment that holds PCI-DSS and ISO 27001 certifications and operates under the CBN.
  • Our environment is heavily integrated and highly automated.
  • We've built an identity lifecycle that flows automatically from our HR systems into our identity provider.
  • Macs deploy zero-touch, and access requests provision themselves.
  • As our scale and complexity increase, we are bringing on a Senior IT Infrastructure Engineer to expand our engineering capacity and provide critical redundancy across our Tier-1 systems.
  • Reporting directly to the Head of IT, you will help drive, manage, and maintain this integrated ecosystem while executing on our long-term infrastructure roadmap.

We'll trust you to

  • Drive Identity Management: Manage our identity lifecycle. You will configure SAML and OIDC across our application estate, maintain SCIM provisioning, manage attribute-driven RBAC, and enforce phishing-resistant authentication.
  • Maintain Lifecycle Automation: Support and improve the joiner/mover/leaver pipeline. Build automated processes for accessmenent from approval to access provisioning
  • Manage the Fleet & Device Trust: Oversee our macOS environment. This includes automated enrollment, configuration profiles, EDR, and enforcing DLP on outsourced devices. You will help maintain device trust as a real, certificate-backed control that rejects unmanaged or unpatched devices.
  • Maintain Global Networks: Manage the physical network across six locations. You'll handle multi-WAN failover, VLAN segmentation, centrally managed wireless/switching, server rooms, and the carrier connectivity linking our on-premise infrastructure to the cloud.
  • Drive the Zero Trust Migration: Help us execute the transition away from legacy VPNs. You will drive our move to Zero Trust Network Access (ZTNA), enforcing per-application authorization based on real-time device posture.
  • Build as Code: Treat the IT environment as code. You'll use Terraform, Git-based staging-to-production pipelines, and Python/Bash where no provider exists. Your first instinct should always be to reach for an API before logging into an admin console.
  • Enforce Automated Compliance: Turn regulatory requirements into automated controls that generate their own evidence. We balance ISO 27001, ISO 20000, PCI-DSS, NDPR, and the CBN IT Blueprint simultaneously.
  • Resolve Complex Tickets: We all work tickets leadership included. You will handle complex escalations and diagnose faults that span a firewall, a carrier, and a cloud provider all at once.
  • Document for the Future: Write documentation to a standard that survives your absence.

You'll thrive in this role if you have

  • 5+ years in infrastructure or systems engineering, ideally including time on a small, high-leverage team.
  • Real depth in at least two of the four areas below, and enough baseline competence in the rest to handle an escalation (we are not looking for a unicorn who is a master of all four):
  • Identity & Access Management: SAML 2.0, OIDC, OAuth 2.0, SCIM 2.0, LDAP, WebAuthn/FIDO2. You have actually built lifecycle automation, not just clicked through SSO setup wizards.
  • Endpoint Management at Scale: Apple MDM protocols, zero-touch enrollment, declarative configurations, and compliance enforcement across hundreds of devices.
  • Network Engineering: Multi-site and multi-carrier setups, VLANs, complex routing, firewall policies, multi-WAN failover, 802.1X, and RADIUS.
  • Infrastructure as Code: Terraform, Git workflows (with peer review), and enough Python, Go, or Bash to confidently build against a REST API.

You should also have:

  • Experience operating under external assessors with multiple active compliance frameworks.
  • A track record of inheriting live, critical systems and improving them without breaking what already works.
  • The engineering judgment to know when not to automate. (Not everything needs to be code).
  • Strong technical writing skills. You write specs, procedures, and audit responses that other teams can actually understand and act on.

Bonus points if you:

  • Experience with public cloud networking, certificate management, and identity federation.
  • Knowledge of X.509, mTLS, ACME, or SCEP for certificate-backed device identity.
  • Experience using osquery (or equivalent) and turning CIS benchmarks into enforced configurations.
  • Experience enforcing security baselines on BPOs and devices you do not physically own.
  • Tenant-level administration of enterprise collaboration suites, including deep DLP classification.
  • ITSM design experience under ISO 20000 or ITIL.

Benefits

  • Competitive compensation package and benefits
  • 13th month bonus
  • TSG Equity compensation
  • Full medical coverage
  • Wellbeing stipend
  • Hybrid working environment
  • Smart, kind colleagues who are invested in your growth.
