Job Title: Senior SAP Commerce Cloud / Hybris Developer – Durable Workflows
Location: Remote (U.S.)
Employment Type: Contract (W2 through ZipStaff — No C2C or 1099)
About the Opportunity
ZipStaff is seeking a senior SAP Commerce Cloud / Hybris Developer to modernize a large commerce platform through hands-on engineering, durable workflow orchestration, and AI-assisted development for a major retail organization.
This is a hands-on engineering role focused on building reliable, long-running commerce processes that remain correct across failures, deployments, retries, and extended execution periods. Experience with Temporal-style programming models (Temporal, Cadence, Azure Durable Functions, Conductor, or equivalent) is required.
What You’ll Do:
- Develop and support SAP Commerce Cloud capabilities using Java and Spring.
- Build integrations with OCC and REST APIs.
- Design durable workflows for long-running commerce processes (cart workflows, order orchestration, inventory updates, recovery operations).
- Separate deterministic orchestration logic from side-effecting activities.
- Design workflows that support durable state and event-history replay, automatic retries with configurable backoff, idempotent activity execution, timeouts/timers/cancellation, compensation and business rollback, signals/events/external callbacks, human-in-the-loop processing, workflow queries and operational visibility, versioning of production workflows, and safe recovery after worker or dependency failure.
- Establish meaningful workflow identifiers, task queues, concurrency limits, and rate controls.
- Prevent unbounded workflow histories through appropriate continuation and lifecycle strategies.
- Build automated workflow, activity, replay, integration, and failure-path tests.
- Integrate durable workflows with SAP Commerce, Kafka, APIs, databases, and external services.
- Apply AI and context engineering to code discovery, implementation, testing, documentation, incident response, and release analysis.
- Build reusable AI instructions, agent skills, MCP integrations, repository context, and verification guardrails.
- Diagnose SAP Commerce performance issues involving FlexibleSearch, persistence, caching, TaskEngine, Kafka consumers, and database contention.
Required Qualifications:
- 7–8+ years of senior-level experience delivering distributed production systems.
- Strong SAP Commerce Cloud / Hybris (or similar platform) development experience.
- Advanced Java and Spring development skills.
- Experience with React.js and modern JavaScript or TypeScript.
- Hands-on experience with at least one durable orchestration platform (Temporal, Cadence, Azure Durable Functions, AWS Step Functions, Conductor, or comparable).
- Strong understanding of workflow determinism and replay, workflow vs. activity responsibilities, at-least-once execution semantics, idempotency, retry classification, compensation/saga patterns, durable timers, asynchronous events, workflow versioning, and failure recovery.
- Experience designing event-driven integrations using Kafka or comparable messaging technology.
- Demonstrated use of AI coding assistants or agentic engineering tools on substantive software work.
- Practical understanding of context engineering (equipping AI systems with domain knowledge, tools, instructions, examples, and validation).
- Strong automated testing, debugging, performance analysis, and production support skills.
- Must be legally authorized to work in the United States without sponsorship now or in the future.
Preferred Qualifications:
- Temporal Java SDK experience and hands-on operation of Temporal workers, task queues, namespaces, schedules, search attributes, signals, queries, and updates.
- Experience testing workflow replay and safely evolving active workflow definitions.
- Knowledge of Protobuf, schema evolution, and backward-compatible contracts.
- SAP Commerce 2211, Java 21, and Spring 6 experience.
- Experience with OpenTelemetry, Dynatrace, Kubernetes, Azure, and centralized logging.
- Experience building AI agents, MCP servers, reusable agent skills, or retrieval-augmented development systems.
