Job summary

Digital Zone in Turkey is expanding its platform and seeks a seasoned SRE/Platform engineer to scale services across Go, TypeScript, and PHP/Laravel environments. This role focuses on enabling teams through scalable infrastructure and reliable practices.

You will own capacity planning, autoscaling, caching, and the incident lifecycle, driving improvements across the observability stack and automation.

Qualifications

• 5+ years in SRE, platform, or backend engineering with ownership of large-scale systems.
• Proven experience scaling systems during traffic spikes and running load/failure tests.
• Fluent with AWS, Postgres performance, and observability tooling.

Responsibilities

• Build scalability foundations: capacity planning, autoscaling, caching, queues, and graceful degradation.
• Establish load and failure testing as standard practice across teams, with frameworks and runbooks.
• Own SLOs, error budgets, and the observability stack across TypeScript, Go, and PHP/Laravel services; instrument for scale.
• Harden Postgres and AWS infrastructure for performance and availability; automate toil via IaC.
• Lead incident response and blameless postmortems; drive systemic fixes upstream into design and campaign planning.
• Collaborate with engineering teams early on capacity and resilience to enable self-sufficiency in scaling their systems.

Job description

Your mission is to make DigitalZone able to scale. You will build the platform's capacity to absorb campaign-level traffic spikes, and you will give every engineering team the tools, standards, and practices to load- and failure test their own systems. This is an enablement role at its core: you raise the reliability bar across the org by building capability, not by owning every service yourself.

What you'll do

• Build the platform's scalability foundation: capacity planning, autoscaling, caching, queueing, and graceful degradation designed for large campaign spikes rather than steady-state load
• Establish load and failure testing as a standard engineering practice, giving teams the frameworks, tooling, and runbooks to test their own services and act on the results
• Own SLOs, error budgets, and the observability stack (metrics, logs, traces, alerting) across TypeScript, Go, and PHP/Laravel services, and standardize how teams instrument for scale
• Harden Postgres and AWS infrastructure for performance and availability, and reduce toil through automation and IaC
• Lead incident response and blameless postmortems, and drive the systemic fixes upstream into design and campaign planning so reliability is built in, not bolted on
• Partner with engineering teams early on capacity and resilience, acting as the multiplier that makes them self-sufficient at scaling their own systems

What you'll bring

• 5+ years in SRE, platform, or backend engineering, with strong production ownership of large-scale systems operating at 10s of thousands of requests per minute
• A track record of scaling systems through real traffic spikes, and of designing and running load and failure testing programs that other teams adopted
• Deep AWS experience and a solid grasp of Postgres performance and scaling
• Fluency with observability tooling and infrastructure-as-code, plus scripting in Go, TypeScript, or similar
• A calm, systematic approach to incidents, and the communication skills to influence and enable other teams rather than gatekeep

Benefits

• Immediate, large-scale impact on a high-growth business
• Top-of-the-market compensation packages
• Work alongside top regional talent, with team members from Talabat, Careem, Etisalat, and more
