Job title: Senior Technical Customer Support Engineer

Reports to: Team Lead Technical Customer Support Engineer

Department: TRG

Location: Alpharetta, GA

Grade: 18

About the Role:

This role plays a critical part in helping enterprise and strategic partners successfully integrate with and adopt Priority's embedded commerce platform. As the technical lead within Partner Solutions, you will serve as a senior technical authority across partner integrations: working at the intersection of Solution Architecture, Implementation Engineering, Product, Engineering, Technical Account Management, and Technical Support.

You will be hands-on throughout the partner lifecycle, from technical discovery and solution design through implementation and early production support. You will help partners navigate complex APIs, integrations, authentication, transaction flows, data, and distributed systems while ensuring proposed solutions are scalable, supportable, and aligned with the direction of the platform.

Beyond solving individual partner problems, you will identify recurring technical challenges and turn those learnings into scalable solutions - including improved APIs, integration patterns, tooling, documentation, Postman collections, golden-path examples, and AI-enabled workflows. You will help reduce unnecessary demand on core Product and Engineering teams while creating a feedback loop that improves the platform and accelerates partner adoption.

This is a high-impact individual contributor role for an experienced engineer who can operate with technical depth, customer empathy, and strong business judgment. You will lead through expertise and influence rather than direct people management and will be expected to raise the technical bar across the broader Partner Solutions organization

Responsibilities:

• Serve as the senior technical lead and subject-matter expert for complex partner integrations across the Partner Solutions organization.
• Partner with Solution Architects during technical discovery to understand partner business requirements, technical environments, architectures, financial flows, and integration needs.
• Translate partner requirements into scalable technical solutions that leverage Priority's existing products and platform capabilities.
• Help partners and their technical teams understand and successfully integrate with Priority APIs, SDKs, widgets, and other platform capabilities.
• Participate in technical demonstrations and solution discussions with partners, particularly for complex or highly technical use cases.
• Act as a trusted technical advisor to partner engineering teams and technical buyers, building confidence in Priority's platform and proposed solutions.
• Serve as the technical escalation point for complex integration, implementation, API, transaction, and production issues.
• Own complex technical issues through investigation, root-cause identification, resolution, and follow-through.
• Provide hands-on technical leadership during customer implementations, working closely with Implementation Engineers and Technical Project Managers.
• Troubleshoot issues across APIs, authentication, webhooks, transaction flows, application services, data, and distributed systems.
• Use logs, metrics, traces, transaction data, Postman, SQL, and other engineering tools to investigate and resolve complex technical problems.
• Reproduce partner issues and integration failures in sandbox or test environments and develop clear paths to resolution.
• Work directly with Product and Engineering teams to identify defects, technical gaps, and opportunities for systemic improvement.
• Help determine when partner requirements can be addressed through existing platform capabilities versus configuration, integration patterns, custom solutions, or product development.
• Identify recurring partner and integration issues and drive efforts to eliminate root causes rather than repeatedly solving the same problems.
• Establish and promote technical standards, integration patterns, troubleshooting practices, and engineering best practices across Partner Solutions.
• Create reusable technical assets including solution guides, Postman collections, API examples, golden-path implementations, troubleshooting guides, and other integration enablement resources.
• Improve the partner integration experience by identifying opportunities to make integrations faster, simpler, and increasingly self-service.
• Partner with Solution Architects, Implementation Engineers, Technical Account Managers, Product, Engineering, and Support to ensure smooth transitions. across the partner lifecycle.
• Support the 30/60/90-day post-implementation period by helping monitor technical health, resolve issues, and capture learnings for future implementations.
• Ensure technical learnings from partner implementations and support are captured and fed back into Product and Engineering roadmaps.
• Participate in regular deal reviews and technical retrospectives to surface technical risks, unblock opportunities, and identify recurring partner pain points.
• Contribute to technical solution reviews and architectural discussions, ensuring solutions are scalable, reliable, secure, and supportable.
• Build lightweight tools, scripts, automation, and internal capabilities that improve technical investigation, integration, and partner support.
• Drive adoption of AI-enabled technical workflows, including AI-assisted troubleshooting, knowledge retrieval, issue summarization, integration guidance, and agent/MCP-based solutions.
• Use AI-assisted development tools to accelerate technical problem solving while maintaining appropriate technical review, accuracy, security, and quality.
• Mentor and coach other engineers and technical team members through pairing, technical reviews, knowledge sharing, and hands-on problem solving.
• Raise the overall technical capability of the Partner Solutions organization by creating reusable knowledge, patterns, and solutions.
• Represent Partner Solutions in technical discussions with internal stakeholders and, when appropriate, directly with strategic partners.
• Continuously identify opportunities to improve Partner Solutions' ability to scale without increasing dependency on individual experts or core Product and Engineering teams.

What Success Looks Like:

• Partners have a high-quality, technically credible experience from discovery through implementation and early production.
• Complex partner integrations are solved quickly, accurately, and with clear technical ownership.
• Partners and their engineering teams view Priority's Partner Solutions organization as trusted technical advisors.
• Technical discovery results in scalable solutions that minimize unnecessary custom development, refactoring, and future migration effort.
• Partner implementations are completed more quickly, with fewer technical blockers and less rework.
• The Technical Lead is consistently relied upon as the escalation point for the organization's most complex technical challenges.
