Job summary

JobCubby is seeking a senior SRE to own reliability across our large-scale platform, handling tens of thousands of requests per minute. You will shape capacity planning, implement autoscaling, caching, queues, and graceful degradation to survive campaign spikes.

You will lead load testing, define SLOs and error budgets, manage the observability stack, and Harden Postgres and AWS. Collaborate with engineers early to multiply their scaling and resilience in a fast-growing environment.

Qualifications

• 5+ years in SRE, platform, or backend engineering with ownership of large-scale systems.
• Experience scaling systems against real traffic spikes.
• Deep AWS experience and Postgres performance tuning.
• Fluency with observability tools and IaC; scripting in Go or TypeScript.
• Calm, methodical incident response and cross-team communication.

Responsibilities

• 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.

Job description

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.

• 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
