The Senior Software Engineer will join Apple's Wallet, Payments, and Commerce (WPC) team, focusing on building and operating critical systems that support Apple Pay and related services. This role emphasizes designing observability platforms, reliability tooling, and AI-powered automation to enhance system performance and user experience. The engineer will tackle complex challenges at the intersection of payments infrastructure and DevOps tooling. The position requires strong design and architecture skills to ensure high standards of availability, security, and correctness.

• 7+ years of experience in software engineering with a strong emphasis on building backend systems, platforms, and tooling.
• Proven experience building observability or reliability tooling such as monitoring systems, alerting platforms, log pipelines, tracing infrastructure, or diagnostic tools.
• Deep technical understanding of the Otel ecosystem, including configuring Collectors, SDKs, and Exporters.
• Strong proficiency in Kotlin, Go, Python, or Java, with Kotlin experience highly valued.
• Deep understanding of distributed systems concepts including data pipelines, event-driven architectures, API design, and service-to-service communication.
• Experience designing systems that handle high-throughput data ingestion and processing such as telemetry pipelines, streaming systems, or transaction processing platforms.
• Solid understanding of datastores and their trade-offs including relational databases, NoSQL, time-series databases, caching layers, and message brokers.
• Working knowledge of production infrastructure concepts including containers, Kubernetes, cloud platforms, networking fundamentals, and CI/CD systems.
• Experience with observability platforms and standards such as Prometheus, Grafana, Datadog, OpenTelemetry, Splunk, or similar.
• Hands-on experience with LLMs and AI APIs, building integrations, agents, or automation pipelines that solve real operational problems.
• Experience building internal developer tools, platforms, or CLIs that are adopted and used daily by engineering teams.
• Familiarity with SRE practices including SLOs/SLIs, error budgets, incident management, and post-incident review.
• Strong software design skills, writing clean, well-tested, maintainable code and caring deeply about system architecture.
• Excellent communication and collaboration skills with the ability to lead design reviews and drive technical alignment across teams.
• BS or MS in Computer Science, Software Engineering, or a related field, or equivalent professional experience.
• Experience working on payment systems, financial services platforms, or other high-compliance, high-availability domains.
• Experience applying AI/ML to operational problems such as anomaly detection, transaction pattern analysis, log summarization, automated diagnostics, or intelligent alerting.
• Familiarity with security and compliance considerations in financial and payment systems including PCI-DSS, tokenization, encryption at rest and in transit.
• Experience with Infrastructure-as-Code tools such as Terraform or Pulumi as a tooling builder.
• Experience building systems that require strong correctness guarantees including idempotency, exactly-once processing, auditability, and data integrity at scale.

• Design and develop observability platforms and reliability tooling for WPC engineering teams.
• Implement AI-powered automation to enhance system performance and user experience.
• Collaborate with cross-functional teams to resolve issues in real time.
• Ship production-quality software that supports Apple Pay and related services.
• Ensure high standards of availability, latency, security, and correctness in systems.
