Job description

Office requirement: Hybrid with two days a week in office

Employment type: Full Time Permanent

At GWI we’re always looking for extraordinary people who thrive on making an extraordinary impact. Right now we’re looking for a Sales Engineer to play a key role in our Revenue team in London. If that’s you and making a difference gets you out of bed in the morning, keep reading. It could be the start of something well extraordinary.

Sounds great: what will I be doing

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. Serve as the technical lead in the pre‑contract phase engaging with prospects to define solution approaches, demonstrate capabilities and ensure proposed integrations are feasible and aligned with business objectives. Post‑sale hand over the detailed solution design to the Solution Architect function for deeper technical execution and customer onboarding.

Key Responsibilities

Pre‑Sales Technical Leadership

• 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 any blockers and mitigation strategies before contract close.
• Translate business requirements into high‑level architecture diagrams, integration workflows and technical statements of work.
• Be a 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.

Solution Proposal & Documentation

• 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.

Collaboration & Feedback Loop

• 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.

It’s also fun; shaking things up is what working for a growing company is all about. So you’ll need to be flexible, comfortable with continuous change and working in a high‑tempo environment as we grow.

What do I need to bring with me

You’ll need to be able to demonstrate the core skills this role requires. You don’t have to tick all the boxes right away; the important thing is that you’re willing to learn. Here’s what the team will be looking for:

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).

Familiarity with common integration patterns (ETL, webhooks, event streaming, middleware, orchestration).

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

Comfortable in fast‑paced sales cycles balancing multiple opportunities simultaneously.

Equally important is attitude. We want people who think big (to make an impact), ask why (to find a better way) and show respect (to everyone at every level all the time). Those are our values exemplified by our leadership team and they’re a big part of what we’re looking for in you.

Interview steps

• Preliminary phone call with the Talent Team (no video required)
• 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.
