Job summary

Apple Pay seeks an Architect to set the technical direction for reliability, scalability, and availability of Apple Pay's distributed systems at global scale. You will define metrics, SLOs, incident postmortems, and guide teams across client, server, and devops to ensure architecture decisions reflect real-world operations.

You will review designs for resilience, write prototypes, lead incident reviews, and mentor engineers on distributed systems fundamentals such as replication, partitioning,

Qualifications

• Proven track record designing and operating distributed systems at scale in high-throughput, low-latency production environments.
• Deep expertise in distributed systems fundamentals: replication, partitioning, consensus, and failure handling across partitions.
• Hands‑on experience defining and instrumenting metrics for availability and scalability (SLOs, error budgets, tracing).
• Experience with scalable system building blocks: load balancing, caching, messaging/streams, database sharding, service mesh.

Responsibilities

• Guide the evolution of Apple Pay's distributed systems with a clear point of view on trade-offs appropriate to payment-critical infrastructure.
• Define and drive reliability engineering practices across the org: SLIs/SLOs/SLAs, capacity planning, failure-mode analysis.
• Establish observability and metrics strategy for latency, traffic, errors, tracing, and alerting.
• Collaborate with engineering teams to review designs for scalability bottlenecks and resilience gaps.
• Write code and prototypes to validate architectural decisions and unblock teams.
• Lead incident reviews and postmortems to drive systemic fixes, not patches.
• Mentor engineers on distributed systems fundamentals and trade-offs.

Job description

New York City, New York, United States Software and Services

Apple Pay builds and operates the systems that power Apple Pay transactions at global scale, where downtime or a scalability shortfall means a failed payment for a real person at a register or checkout. This Architect role is responsible for setting the technical direction for how Apple Pay's systems achieve reliability, scalability, and availability — not just in design docs, but in the metrics, SLOs, and operational practices that hold them accountable in production. It is a role for someone with strong, well-reasoned opinions about how distributed systems should behave under load, failure, and partial degradation, and who can translate those opinions into concrete architecture, tooling, and team practices across the org.

Description

The Architect will own the technical direction for Apple Pay's distributed systems — driving reliability engineering practices, observability strategy, and scalability architecture across a high-throughput, payment-critical infrastructure. Day to day, this means reviewing designs for resilience gaps, writing code and prototypes to validate architectural decisions, and leading incident reviews and postmortems that drive systemic fixes. The role also involves close collaboration with client, server, devops, and product engineering teams to ensure architecture decisions account for real-world operational constraints at Apple's global scale.

Responsibilities

• Guide the evolution of Apple Pay's distributed systems with a clear point of view on trade-offs (consistency vs. availability, latency vs. durability, cost vs. redundancy) appropriate to payment-critical infrastructure
• Define and drive adoption of reliability engineering practices across the org: SLIs/SLOs/SLAs, error budgets, capacity planning, and failure-mode analysis tailored to systems where correctness and availability directly affect transaction success
• Establish the observability and metrics strategy needed to operate payment systems reliably at scale — including latency, traffic, errors, distributed tracing, and alerting that reflects real transaction impact
• Partner with teams across Apple Pay to review designs for scalability bottlenecks, points of failure, and resilience gaps
• Write code and prototypes where it matters — diving into the codebase to validate designs, unblock teams, or resolve production issues
• Lead technical reviews and postmortems for major incidents affecting Apple Pay systems, driving systemic fixes rather than one-off patches
• Mentor engineers on distributed systems fundamentals: consensus, replication, partitioning, idempotency, exactly/at-least-once semantics, and trade-offs relevant to payment processing
• Collaborate with client, server, devops, and product engineering teams to ensure architecture decisions account for real-world operational constraints (deployment, rollback, multi-region failover, capacity headroom) at Apple's global scale

Minimum Qualifications

• Proven track record designing and operating distributed systems at scale in high-throughput, low-latency production environments
• Deep expertise in distributed systems fundamentals: replication, partitioning/sharding, consensus protocols, eventual vs. strong consistency, idempotency, and failure handling across network partitions
• Hands‑on experience defining and instrumenting metrics for availability and scalability (e.g., SLOs, error budgets, distributed tracing) and using them to drive concrete engineering decisions
• Strong background in the building blocks of scalable systems: load balancing, caching layers, message queues/event streaming, database sharding/replication, service mesh, and rate limiting/backpressure mechanisms
• Demonstrated ability to set technical direction across multiple teams without direct management authority, and to communicate trade‑offs clearly to both engineers and leadership
• Track record of leading incident reviews or reliability programs and turning postmortem findings into durable systemic improvements
• Skilled at operating with ambiguity across large, complex system landscapes and driving alignment across multiple teams and stakeholders

Preferred Qualifications

• Experience with multi‑region or globally distributed systems, including failover and disaster recovery design at scale
• Prior experience in payments, fraud/risk systems, or other regulated, high‑availability financial infrastructure
• Contributions to open‑source distributed systems projects or published technical writing on the subject
• Experience establishing or maturing a devops/reliability practice within an organization
