Technology is one of Targets top four enterprise priorities. It plays an outsized role in powering growth speed reliability and innovation across the company. From merchandising and supply chain to stores and digital our technology platforms directly enable the most critical outcomes for 2026 and beyond.

Target Tech builds and operates the intelligence powered architecture that fuels these outcomes. Our teams design scalable platforms modern data ecosystems and resilient infrastructure that allow thousands of engineers to deliver secure high performing systems at enterprise scale.

About the Observability Team

Reliability is foundational to delivering on Targets purpose. Every register scan Drive Up order search result inventory update and fulfillment workflow depends on systems that are resilient measurable and continuously improving.

The Observability team builds and operates the enterprise platform that enables engineering teams to understand measure and improve the reliability and performance of their products. We provide standardized telemetry logging tracing metrics alerting system maps and operational insights across more than 20000 services. Our platform enables:

• Enterprise-scale metrics logs and traces built on OpenTelemetry standards
• Real-time system maps and dependency graphs across complex service ecosystems
• SLO management error budget tracking and reliability showback
• Integrated alerting on-call alignment and actionable operational insights
• AI-driven root cause analysis and automated remediation capabilities

We operate at massive scale in 24x7 production environments. Technologies commonly used across the team include Golang Kubernetes Kafka ClickHouse InfluxDB Grafana React and distributed systems patterns that support high-volume telemetry pipelines. We are moving beyond traditional monitoring: our ambition is an intelligent agent-enabled observability platform that proactively detects degradation explains system behavior and recommends or executes recovery actions before guests are impacted.

About the Role

As a Principal Engineer you are the senior-most individual-contributor technical leader on the Observability team. You partner closely with three Senior Engineering Managers and product leadership to set the technical vision architecture and standards for a unified intelligent reliability platform serving all of Target Tech. This is a hands-on technical leadership role: you lead through depth design and influence rather than through direct reports.

Principal Engineers operate at the overall Infrastructure level. While you are assigned to a domain in this case Observability you are expected to contribute meaningfully to broader Infrastructure priorities including initiatives and problems that lie outside your assigned team. Your expertise is applied wherever it moves the wider organization forward.

You will be accountable for:

• Technical direction. Owning the end-to-end architecture of the observability platform metrics logs traces alerting SLOs system maps and AI-driven root cause analysis across teams and roadmaps.
• The hardest problems. Solving the distributed-systems and high-volume telemetry-pipeline challenges where vendor defaults break down at Target scale and no standard playbook exists.
• Platform as a product. Driving observability as an internal product with first-class developer experience self-service adoption and observable by default instrumentation embedded directly in developer workflows.
• Engineering standards. Setting technical standards leading design and architecture reviews and multiplying the effectiveness of engineers across all three teams.
• Infrastructure impact. Contributing to Infrastructure-wide technical priorities beyond Observability applying your judgment and expertise to problems that span teams and domains.
• Enterprise influence. Representing Observability in cross-domain and enterprise architecture forums and aligning the platforms direction with the broader Target Tech strategy.

Success in this role requires exceptional technical judgment clear communication operational discipline and the ability to drive clarity and consensus in ambiguous high-scale environments.

What Were Looking For

This role is defined by three pillars. We expect a Principal Engineer to be outstanding across all three:

Technical Depth. Deep current expertise in distributed systems and high-volume telemetry pipelines OpenTelemetry internals columnar and time-series storage and query engines (e.g. ClickHouse InfluxDB) streaming with Kafka and performance cost and reliability engineering at scale. You can go deep enough to debug the pipeline and broad enough to shape the platform.

Technical Leadership. Proven ability to influence across an organization without direct authority setting standards driving architectural consensus and mentoring senior engineers. You raise the technical bar of everyone around you and bring clarity to ambiguous contested problem spaces.

Platform / Product. A product mindset toward internal platforms. You measure success by adoption and developer experience not just capability designing self-service reducing friction and making reliability and instrumentation the path of least resistance for thousands of engineers.

Why This Role Is Compelling

This role sits at the center of one of Targets top enterprise priorities. You will directly shape how reliability performance and operational intelligence are delivered across the company. You will:

• Influence how thousands of engineers build and operate software
• Shape the evolution from reactive monitoring to AI-assisted and autonomous reliability
• Protect revenue brand trust and guest experience through resilient platform design
• Solve distributed systems challenges at enterprise retail scale that are not in any playbook
• Play a visible senior role in advancing Targets intelligence-powered architecture

If you are motivated by scale impact and deep technical challenges this role offers all three.

What Success Looks Like

Within 12 to 18 months you will have:

• Ratified a clear platform architecture and technical roadmap adopted across the three engineering teams
• Delivered measurable improvements in telemetry-pipeline scale cost efficiency and query latency
• Raised standard-telemetry adoption and observable by default developer experience across production TAP applications
• Reduced mean time to detect and mean time to engage during critical incidents through better platform capabilities
• Strengthened the senior engineering bench through design leadership mentorship and durable technical standards
• Made a visible meaningful contribution to at least one Infrastructure-wide priority beyond Observability applying your expertise across teams and domains

About You

You are a technical leader who leads through depth and influence. You are energized by architecture telemetry design distributed systems and failure analysis and equally by helping other engineers grow in scope and impact. Desired experience includes:

Building and operating large-scale telemetry or data-intensive distributed systems

• 4 yeardegree or equivalent experience. Continuing education to maintain thorough knowledge of technical domains along with staying current in latest technologies
• 12 years of experience in technology development or services
• 4 years of experience in strategic planning and setting technical direction
• Supporting and operating 24x7 business-critical capabilities
• Instrumenting products with metrics logs and traces to make them observable by default
• Designing and deploying scalable APIs and microservices
• Working with streaming and columnar/time-series data stores (e.g. Kafka ClickHouse InfluxDB)
• Depth in one or more platform languages such as Golang and orchestration with Kubernetes
• Using version control (Git) and working in Linux/Unix-based environments
• Communicating complex technical solutions clearly across diverse technical and non-technical audiences
• Working effectively across multiple teams in a product-oriented environment
• Experience in Java/ J2EEsql/ no-sql(postgremongoDB Cassandra graph structure etc.) Python Ruby Chef Drone Kubernetes containers Cloud tech etc.

Minimum Qualifications

• In-depth knowledge of system design build test and operational debugging practices
• Demonstrated experience architecting and delivering production distributed systems at scale
• A track record of sustained technical influence and standard-setting across multiple engineering teams
• Commitment to continuous learning and staying current with evolving technologies
