Job description

Overview

As our Sales Engineer you'll partner with sales teams to win business by translating customer needs into clear, technically sound API and data solutions.

Post-sale, hand over the detailed solution design to the Solution Architect function for deeper technical execution and customer onboarding.

Responsibilities

• Partner with Account Executives during the sales cycle to assess customer requirements and propose optimal API and data integration solutions.
• Lead technical discovery sessions with prospects to understand existing systems, data flows, and integration constraints.
• Articulate and demonstrate API capabilities, data models, and integration patterns to both technical and business stakeholders.
• Evaluate technical feasibility of proposed solutions, identifying blockers and mitigation strategies before contract close.
• Translate business requirements into high-level architecture diagrams, integration workflows, and technical statements of work.
• Powerful asset and partner for Product Marketing when rolling out new launches to the field, building new demo assets and then iterating and providing feedback on how these land with customers, gaps in functionality etc.
• Create and maintain pre-sales technical assets, including demo environments, sample API calls, code snippets, and reference integrations.
• Provide clear documentation of proposed integrations for smooth transition to the Solution Architect post-contract.
• Collaborate with product and engineering teams to validate solution approaches and ensure alignment with platform capabilities and roadmap.
• Act as the bridge between sales, product, and engineering during the sales process.
• Capture market and prospect feedback on API/data features to inform product development.
• Support RFP responses with technical input, diagrams, and integration feasibility assessments.

• First video interview with the hiring managers
• Second (and final) video interview with the hiring panel, often including a presentation, followed by a values conversation with members of the wider GWI community.
• Don’t be alarmed if there are other stages in the process, it’s all part of the plan for some of our roles.

Requirements

• Proven experience as a Pre-Sales Engineer, Sales Engineer, or Solutions Consultant role with a focus on APIs, SaaS platforms, or data integrations.
• Strong understanding of REST API design, authentication (OAuth, JWT), and data formats (JSON, XML, CSV).

• Strong verbal and written communication skills, able to explain technical solutions to mixed technical/business audiences.
