Senior Software Engineer (Observability Solutions) - Enterprise Technology Services

Apple IS&T’s infrastructure powers billions of transactions every day. At this scale, the systems we build must be resilient, observable, and extraordinarily efficient. We are looking for a Senior Software Engineer with deep expertise in Go and distributed systems to join our team and help architect the next generation of Observability Platform.

This is a senior individual contributor role where your technical judgment will directly shape system architecture, team direction, and engineering culture. You'll collaborate across teams, mentor engineers, and take end-to-end ownership of a mission-critical service.

Our team is building an observability platform that supports some of Apple IS&T’s most critical and high-traffic services. We are designing a platform that must remain consistent and performant even as it grows to handle petabytes of data resulting from billions of daily transactions.

As a Senior Software Engineer, you will be a technical anchor for the team. You won't just write code — you'll define how we build, shape our architectural direction, and raise the engineering bar across every layer of the stack. You'll partner directly with peer architects to translate ambiguous, high-stakes problems into concrete, elegant solutions.

Responsibilities

• Architect and deliver highly available, fault-tolerant distributed system that operate reliably at petabyte scale.
• Design and build core backend services in Go, with a deep focus on performance, correctness, and operational simplicity.
• Drive technical strategy and architecture decisions.
• Lead technical design reviews and establish engineering best practices across the team.
• Identify performance bottlenecks and drive systematic improvements across the stack.
• Mentor and grow engineers across experience levels through code reviews, design discussions, and 1:1 coaching.

Minimum Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, or equivalent.
• 3 or more years of experience in Go.
• Hands-on experience building or scaling systems that handle large data workloads
• Hands-on experience on RDBMS or NoSQL.
• 10 years or more of overall experience.

Preferred Qualifications

• Experience building or operating observability platforms — including metrics pipelines (Prometheus), log aggregation (Elasticsearch), and Application Performance Monitoring (APM) tools.
• Experience designing and operating distributed systems
• Strong understanding of database internals — including storage engines, query optimization, transaction management, indexing strategies, and consistency models.
• Proficiency in Go (Golang) with production experience building backend services or infrastructure components.
