Distinguished Tech Innovator: 3Pillar warmly extends an invitation for you to join an elite team of visionaries. Beyond software development, we are dedicated to engineering solutions that challenge conventional norms. Envision you: steering the foundational architecture that will enable a major financial services client to transition from a 12-week regression testing cycle to a 2-week continuous delivery model. Your invaluable expertise will serve as the cornerstone in shaping the future direction of our testing frameworks, utilizing cutting-edge agentic development to accelerate automation.

This role transcends the ordinary realms of coding; it's about orchestrating technological marvels that disrupt industries. Seize this extraordinary opportunity to lead a team that is actively shaping the tech landscape for our clients, and sets global standards along the way.

Responsibilities

• Independently guide the technical direction and implementation of core testing frameworks (Desktop Harness, Vendor Simulation, Document Verification) from conceptualization to deployment within a rapid 2-month initial build phase.
• Evaluate trade-offs between correctness, robustness, performance, and customer impact to ensure the development of highly scalable automation frameworks, with client success at the forefront.
• Create and lead the team's technical documentation and repository management practices, ensuring a seamless handover of the established frameworks to the QA automation team.
• Collaborate with the Solutions Architect, Product Development Manager, and client stakeholders to provide necessary oversight of architecture and dependencies influencing product strategy and direction.
• Contribute to code reviews, documentation, and addressing complex bug fixes with a focus on auto-healing capabilities, performance, and reliability.
• Be an active leader in the Engineering Practice community, mentoring QA Engineers as they transition to utilizing the new frameworks across multiple workstreams.

Requirements

• A minimum of 7+ years of experience/expertise working as a Full Stack or Framework Engineer, with proficiency in the specified technologies.

• Strong proficiency in .NET, WPF, and WinForms required to evaluate and build custom automation test harnesses.

• Extensive experience with API mocking, simulation layers, and API testing tools such as GraphQL and Pact.js.

• Demonstrated experience using agentic development tools (e.g., Autogent, GitHub Copilot) to accelerate code and framework generation.

• High level of English proficiency required to interact with a globally-based development team.

• US-based alignment required for this specific engagement.

• Demonstrated experience following and adapting high-level architecture to project and client needs, with the ability to verify/validate architecture implementations.

• Desktop Application Test Harness Deliverables

  • Evaluate tooling and build a test harness for a WPF/WinForms Windows client application.
  • Validate automated interaction patterns against static administrative screens to enable reliable UI-level testing.

• Integration & Vendor Simulation Deliverables

  • Design and develop an MVP simulation and mocking architecture for 2-3 high-value vendor integrations.
  • Scale reusable mocking patterns to support approximately 80 third-party API integrations that restrict direct platform automation.

• Document Verification Deliverables

  • Build an automated verification pipeline template that complements the client's existing Azure Document Intelligence system.
  • Implement validation logic to automatically extract and verify calculated values (rates, fees, payments, escrow) from generated mortgage PDFs.

• Quality, Reliability & Collaboration Deliverables

  • Harden all frameworks and successfully hand them off to the QA execution team by the end of Month 2.
  • Provide tapered technical support (25% allocation), troubleshooting, bug fixes, and edge-case framework extensions during Months 3 through 6 as the QA team scales velocity
