What You'll Do As a Staff Software Development Engineer on the Connectors Engineering – SAP Portfolio team, you'll be the senior, hands-on technical resource for Ava Tax's most complex SAP implementations. You'll work directly with Certified Implementation Partners (CIPs) and customer IT/Basis/ABAP teams to diagnose and resolve technical issues that arise while deploying Ava Tax and related products across SAP ECC, SAP S/4

HANA (Private Cloud), and SAP S/4

HANA Public Cloud. You'll own problems end-to-end rather than routing them — debugging ABAP code, dumps, and BAdI/enhancement logic, navigating SAP S/4

HANA Public Cloud's Clean Core extensibility model (BTP, CDS views, restricted BAdIs), and resolving the large majority of issues yourself. You'll escalate to Connector Engineering only when an issue is a confirmed product defect, packaging it with the reproduction steps, logs, and traces engineering needs to act quickly. In doing so, you'll protect engineering's roadmap capacity, strengthen Avalara's credibility with high-stakes enterprise SAP partners, and help build the runbooks and mentoring that raise the broader SAP Tax Technology team's troubleshooting capability over time.

What Your Responsibilities Will Be Technical Ownership & Direct Issue Resolution Serve as the primary technical owner on partner-led and direct SAP implementation projects, joining CIP calls with the depth and authority to resolve issues on the spot. Diagnose technical issues from functional consultants, partners, and customers — spanning connector behavior, ABAP customization, BTP configuration, BAdI/enhancement logic, SAP Basis, or customer-specific code — and resolve them directly in the majority of cases.

Escalate to Connector Engineering only for confirmed product defects, with full reproduction steps, logs, and ABAP traces included. Own issues to full closure; success is measured by resolution, not hand-off speed. SAP Technical Troubleshooting & Debugging Debug live issues across SAP ECC, S/4

HANA Private Cloud, and S/4

HANA Public Cloud, including ABAP debugging, dump analysis, and connector/interface tracing. Review and advise on custom BAdI implementations, user exits, and enhancement logic partners/customers use to extend Avalara connector functionality (e.g., Flex Mapper custom field mapping, address validation BAdIs). Navigate SAP S/4

HANA Public Cloud's extensibility model (BTP, CDS views, restricted BAdI framework) to find compliant technical paths where standard extensibility is limited. Apply first-principles troubleshooting to distinguish connector defects from customer configuration, custom code, or platform issues. Understand tax calculation, VAT, and e-invoicing concepts — including country-specific mandates such as real-time reporting and clearance models — well enough to troubleshoot where they intersect with SAP tax determination and connector behavior.

Integration & API-Level Diagnostics Use REST API tooling (Postman, SOAP UI) and log/trace analysis to reproduce issues with evidence, inspecting JSON/XML payloads, authentication, and sync vs. async processing. Analyze connector, ERP-native, and internal logs/traces to pinpoint failure points and separate configuration, data, platform, and product-defect causes. Prepare escalation-ready diagnostic artifacts (repro steps, payloads, logs, error codes, business impact) for the rare genuine engineering escalations.
