Senior Infrastructure Engineer: Databases

About Lesaka

Lesaka Technologies is a Southern African fintech building the connected ecosystem for financial inclusion -

transactional banking, lending, insurance, payments and cash management for merchants, consumers and enterprise

clients across the region. We're publicly listed (Nasdaq: LSAK / JSE: LSK) and growing fast.

Lesaka Enterprise runs the payment and token-vending platforms that banks, utilities and large retailers depend on every

day.

The role

Our payment platforms run on data that cannot be lost, late or wrong. You'll be the senior hands-on owner of the

database layer beneath them: its availability, performance, security and recovery. You'll work with engineering and

operations to keep it fast, resilient and audit-ready as volumes grow.

What you'll own

• Design, build and run production database platforms (SQL Server, PostgreSQL and MySQL) across on-premises and

cloud.

• Deliver high availability and disaster recovery, with tested failover and recovery objectives you can prove.
• Tune query and platform performance before slow queries become incidents.
• Plan and execute migrations, upgrades and patching with minimal downtime.
• Define and enforce database security: access control, encryption, auditing and compliance evidence.
• Automate provisioning, backup, monitoring and alerting using infrastructure as code.
• Lead database incident response and root-cause reviews through to permanent fixes.

What you bring

• 6+ years in database administration or infrastructure engineering on high-volume production systems.
• Deep, hands-on expertise in at least two of SQL Server, PostgreSQL and MySQL.
• Proven experience with replication, clustering, backup and recovery design.
• Strong performance tuning skills: execution plans, indexing, locking and capacity planning.
• Infrastructure-as-code and scripting experience (Terraform, Ansible, PowerShell or Python).
• Experience with monitoring and observability tooling.
• Working knowledge of regulated environments (PCI DSS, SOX or similar).

Nice to have

• Cloud-managed database experience (AWS RDS/Aurora or Azure SQL).
• Experience in payments, banking or other transaction-heavy environments.
• Kubernetes or containerised database workloads.

Our culture - what we expect from you

Lesaka is a fast-paced fintech. The people who thrive here have a few things in common:

• Ownership. You don't wait to be asked. If something is broken or unclear, you call for the ball and fix it.
• Fast adaptation. Priorities shift, markets move, regulations change. You don't flinch - you re-plan and move.
• Execution mindset. Ideas are cheap. Shipping is the job. You walk slow, run fast: think it through, then move with

urgency.

• Customer first. The merchant, consumer or enterprise client is why we exist. Your decisions trace back to them.

If you'd rather optimise a process to perfection over six months than ship something useful in six weeks, this won't be the

right fit.
