Position: Performance Engineering Architect – ERP (SAP/Oracle/Workday/Dynamics)
Location: San Diego, CA
Job Type: 3 Days a week Onsite
Shift: General
We are seeking a Performance Engineering Architect with deep expertise in ERP platforms to own end-to-end performance strategy, architecture, and engineering. You will define and enforce non-functional requirements (NFRs), design scalable & resilient ERP architectures, lead performance testing (load, stress, soak, scalability, reliability), and drive observability and tuning across application, integration, database, and infrastructure layers. This role partners closely with Enterprise/Solution Architects, ERP product teams, SRE/Cloud Ops, DBAs, and QA to ensure our ERP solutions meet throughput, latency, and availability objectives at scale.
Key Responsibilities:
Architecture & Strategy
Define and own Performance Architecture for ERP landscapes (core, integrations, customizations, extensions, analytics/reporting).
Translate business SLAs into NFRs (response time, concurrency, throughput, error budgets, availability, capacity headroom).
Design for scale, burst, and resilience: partitioning, CDN, caching (Redis/Coherence), connection pooling, async patterns, backpressure, batching, circuit breakers, message queuing.
Create reference architectures & performance blueprints for ERP modules (e.g., Order-to-Cash, Procure-to-Pay, HCM/Payroll, Financial Close).
Lead capacity modeling & forecasting (peak seasons, payroll runs, quarter-end close, Black Friday) and right-sizing (cloud compute/storage/network).
Performance Engineering & Testing
Define end-to-end performance test strategy, scenarios, and workloads (API/UI, batch jobs, integrations, EDI, middleware, reports).
Establish test data strategies (volume, variety, privacy/compliance, synthetic data) and environment parity with production.
Lead execution of load, stress, endurance/soak, spike, failover tests; analyze results to identify bottlenecks & regressions.
Build performance regression pipelines integrated into CI/CD with automatic baselining and SLO/SLA gating.
Observability, Diagnostics & Tuning
Implement observability (APM, distributed tracing, metrics, structured logs, RUM) across ERP, middleware, and integrations.
Perform deep-dive profiling: thread/heap analysis, GC tuning, SQL plan analysis, network profiling, JVM/CLR/Node tuning.
Optimize databases & reports (indexes, partitioning, materialized views, HANA modeling, parallelism, statistics, hints).
Drive middleware/integration optimization (JMS/Kafka, MuleSoft/Boomi/OIC, API gateways, ESB, ETL/ELT).
Champion cost-aware performance (FinOps) to balance latency/throughput vs. TCO.
Governance & Leadership
Establish performance guardrails and readiness criteria for go-live and significant releases.
Run performance triage/war rooms, produce exec-ready dashboards & root-cause analyses, and lead remediation plans.
Mentor engineers, uplift squads on performance-first design and coding patterns.
Align with security on TLS overhead, WAF rules, bot mitigation, DDoS preparedness, and zero-trust implications on performance.
Required Qualifications
10–15+ years in performance engineering, with 7+ years hands-on in ERP platforms (SAP S/4HANA/ECC, Oracle E‑Business Suite/Oracle Cloud ERP, Workday, Microsoft Dynamics 365).
Proven leadership of enterprise-scale ERP performance programs (≥5k concurrent users or equivalent batch volumes).
Expert with performance testing tools: LoadRunner/Performance Center, JMeter, NeoLoad, Gatling or k6.
Strong with APM/observability: Dynatrace, AppDynamics, New Relic, Datadog, Prometheus/Grafana, OpenTelemetry.
Deep knowledge of databases: Oracle (AWR/ASH/ADDM), SQL Server, SAP HANA, PostgreSQL; SQL tuning & execution plans.
Solid background in integration/middleware: Kafka/RabbitMQ/JMS, MuleSoft/Apigee/WSO2, SAP PI/PO/CPI, Oracle Integration Cloud, Boomi.
Cloud: AWS/Azure/GCP (Auto Scaling, Load Balancers, managed DBs, caching, storage, network).
Proficiency in one or more languages for tooling/automation: Java, Python, JavaScript/Node, or Go.
Hands-on with CI/CD (Jenkins, GitHub Actions, Azure DevOps), Infrastructure-as-Code (Terraform/CloudFormation), containers (Docker/Kubernetes).
Strong understanding of SRE (SLOs, SLIs, error budgets), resiliency patterns, and chaos testing fundamentals.
Excellent communication: ability to translate performance insights into business impact and executive updates.
