Job Summary

Toshiba Global Commerce Solutions is seeking a Principal Software Engineer Developer Experience Platform to build and operate the engineering system that moves work from requirement through local development focused validation CI/CD deployment and production feedback across a mature retail point-of-sale estate.

This is not an advisory architecture will work directly in Java and JavaScript repositories Maven builds Docker and Kubernetes environments GitLab/Jenkins pipelines platform services andOpenTelemetrytraces. You will reproduce developer friction write the critical code andownimprovements through rollout and adoption.

You will also direct agentic engineering workers AI coding and analysis agents that execute bounded engineering tasks. You will supply context and constraints decompose work supervise executionreviewand correct output enforce deterministic gates and remain accountable for every accepted change.

Developer Experience is treated as an engineering product not a collection of tools. Success means engineers can onboard build test provision deploy diagnose and learn from production with less waiting less cognitive load and fewer manual handoffs.

Mission

Build a developer platform and agentic engineering operating model that lets engineers move from requirement to safe production feedback with less waiting cognitive load and manual coordination. Success isdemonstratedthrough working software faster feedback reliable self-service and sustained adoption not through the volume of diagrams or standards produced.

Engineering Environment

  • A mature POS estate spanning Java and JavaScript applications Maven builds Docker-based local and CI environments Kubernetes and Helm deployment assets and GitLab/Jenkins delivery workflows.
  • Cloud and store-edge software with different connectivity rollout recovery security and operational constraints.
  • A large business-facing Cucumber BDD suite with browser-driven validation seeded test data service dependencies parallel execution and release-gating implications.
  • ExistingOpenTelemetry-based diagnostics and an evolving browser-automation path that must be integrated into useful developer feedback rather thanoperatedas isolated tooling.
  • An expanding agentic engineering model in which AI workersassistwith analysis implementation testing review triage and release preparation under controlled access and deterministic validation.

Key Responsibilities

Hands-On Platform Engineering and Technical Ownership

  • Personally build andoperatedeveloper-facing services command-line tools integrations templates reusable pipeline libraries portal or catalog capabilities and environment automation.
  • Use profiling logs metrics traces and controlled experiments to reproduce bottlenecks andeliminateroot causes across local CI environment deployment and production-feedback workflows.
  • Carrycritical changes from design through code migration deployment runbooks adoption and operational follow-through. A recommendation is not complete until the path works for engineers.

Developer Experience as an Engineering Product

  • Map the end-to-end developer journeyidentifythe highest-cost frictionmaintaina prioritized improvement roadmap and publish clear ownership and service expectations.
  • Use developer research workflow telemetry support demand and delivery data to distinguish systemic constraints from isolated preferences.
  • Maintain platform contracts lifecycle policies deprecation paths and architecture decisions that are backed by working reference implementations and practical migration plans.

Onboarding Local Development and the Inner Loop

  • Create reproducible automated setup for source access dependencies configuration secrets local services test data and development environments.
  • Improve edit-build-test-debug cycles through caching incremental execution targeted validation realistic mocks or service virtualization and actionable local diagnostics.
  • Replace tribal knowledge with executable documentation ownership metadata runbooks and self-service guidance thatremainscurrent because it is part of the delivery system.

Golden Paths and Platform Self-Service

  • Define paved roads for services APIs user interfaces data and configuration security observability testing deployment and store-edge components.
  • Build and govern templates scaffolding reusable libraries pipeline components policy automation and a developer portal or catalog that exposes ownership documentation dependencies health and support paths.
  • Enable on-demand and ephemeral environments preview environments seeded or synthetic test data automated access and lifecycle cleanup throughinfrastructure ascode.

CI/CD Release and Production Feedback

  • Engineer and evolve developer-facing GitLab/Jenkins workflows that provide fast tiered feedback for local changes merge requests integration release qualification deployment and post-deployment verification.
  • Improve build and pipeline performance through profiling caching parallelism dependency discipline failure isolation and clear separation of product test environment and infrastructure failures.
  • Standardize artifact versioning provenance promotion rollback SBOM generation signing and software-supply-chaincontrols without turning routine delivery into a ticket queue.
  • Put logs metrics traces deployment state runbooks and production signals directly in the engineers workflow so failures can be understood andacted onquickly.

Agentic Engineering Workforce

  • Build controlled integrations that give agentic workers least-privilege auditable access to source code work items documentation build systems test systems environments and telemetry.
  • Turn ambiguous engineering goals into bounded agent work packets with repository context architecture constraints acceptance criteria risk test strategy stop conditions and escalation paths.
  • Supervise concurrent agent work detect stalls loops scope drift and conflicting solutions and intervene directly when the work requires Principal-level judgment.
  • Review test andmodifyagent-produced code and analysis. Require deterministic build test security policy and observability evidence before accepting output.
  • Create reusable agent skills and workflows for analysis implementation refactoring test authoring pipeline changes documentation defect triage and release preparation.
  • Measure accepted output rework defect impact cycle-time change and execution efficiency so agentic capacity compounds team output without reducing quality or accountability.

Measurement and Continuous Improvement

  • Own DORA measures together with developer-flow indicators such as onboarding time feedback speed build and test duration environment wait merge-request cycle time cognitive load satisfaction and tooling or process friction.
  • Create end-to-end observability for the developer platform usingOpenTelemetryor equivalent instrumentation including queueing environment readiness pipeline stages failure classes and deployment latency.
  • Use baselines service-levelobjectives experiments and adoption data todemonstrate measurable improvement without degrading quality reliability security or developer sustainability.

Required Qualifications

  • Substantial software engineering or platform engineering experience including sustained Staff or Principal-level influence across multiple teams or products.
  • A recent hands-ontrack recordofpersonallyshipping and operating production platform code automation integrations or delivery infrastructure.
  • Demonstrated success designing and delivering internal developer platforms developer-productivity capabilities or large-scale engineering enablement used in complex production environments.
  • Strong software engineering ability in at least one modern language with the depth to build production-quality platform services integrations automation and reference implementations.
  • Strong experience with CI/CD architecture build systems Maven or comparable tooling GitLab/Jenkins or comparable platforms artifact management and release automation.
  • Strong experience with Docker Kubernetes Helm infrastructure as code environment lifecycle management and cloud and store-edge deployment models.
  • Practical observabilityexpertiseacross metrics logs traces profilingOpenTelemetry service-levelobjectives and failure analysis.
  • Working knowledge of secure software delivery including secrets identity and access policy automation dependency controls SBOMs provenance signing and least privilege.
  • Experience directing AI coding agents or agentic engineering workflows including task decomposition context design tool permissions output review and deterministic validation.
  • Ability to influence globally distributed engineering quality platform security operations and delivery teams without relying on direct reporting authority.

Preferred Qualifications

  • Experience with retail POS payments store systems peripherals or other high-availability edge environments.
  • Experience improving Java and JavaScript workflows across many repositories including portals catalogs scaffolding ownership metadata and platform-product operating models.
  • Understanding of large Cucumber/Selenium or other browser-driven test estates and how specialized test platforms should integrate into the broader developer journey.
  • Experience building agent platforms reusable agent skills model-context integrationsor governedmulti-agent engineering workflows.
