Job description

Build with us

Today, more than 250,000 companies use Mollie to get paid, manage money and grow – with products designed to be simple, scalable, and dependable.

With 950+ Mollies across 14+ locations, we care deeply about autonomy and craft. So we work in small teams, with real ownership, and we trust you to make the right decisions.

We're building for the long term, so we provide the tools you need, processes you can rely on, and a balanced work environment to help you do work you're proud of.

Sales Engineer I

As a Sales Engineer at Mollie, you sit at the intersection of technology and business, supporting our sales team through the pre-sales phase with solutioning, demos, and technical presentations. You are the technical voice in the room for our Netherlands commercial team, helping mid-to-upmarket customers understand exactly how Mollie's payment solutions solve their challenges and close deals through genuine technical value selling.

This role sits within a newly formed professional services structure, separate from the commercial organisation. That means real autonomy in how you work, dedicated leadership focused on craft and efficiency, and a direct line to product teams. You will own the full customer lifecycle from initial discovery through to deal closure, going deep on complex API integrations and custom solutions rather than off-the-shelf implementations.

You are joining at a pivotal moment. Mollie is growing fast in the Netherlands, moving upmarket into more complex, longer deal cycles, and building out Sales Engineering as a true centre of excellence. The work you do here will directly shape how we win in one of our most important markets.

What you'll ship

• Custom technical demos and solution pitches tailored to specific customer problems, built using tools like Postman and AI to bring Mollie's API capabilities to life in a compelling and relevant way
• Deep technical discovery across complex customer cases, from initial sales qualification through to contract signature, ensuring every deal is grounded in a thorough understanding of the customer's environment
• Scalable solutions architecture work that addresses mid-to-upmarket customer challenges, focusing on custom API integrations rather than standard plugin implementations
• Collaborative upsell and revenue initiatives with the CSM team, contributing technical expertise to identify and unlock growth opportunities within existing accounts
• Knowledge-sharing sessions and internal training on Mollie products and the payments market, raising the technical bar across the broader sales and commercial teams
• Structured handovers to post-sales implementation management at contract signature, ensuring a clean and high-quality transition that sets customers up for success

What you'll bring

• 2 to 3 years of experience in a sales engineering, solutions engineering, or pre-sales technical role, ideally with a background in engineering (mechanical, software, or similar)
• A solid understanding of APIs and REST APIs, with hands-on experience using tools such as Postman to build and demonstrate integrations
• Fluency in Dutch and English, with strong communication and presentation skills that allow you to translate complex technical concepts clearly for both technical and non-technical stakeholders
• Proven ability to bridge business and technology perspectives, turning difficult technical problems into clear product solutions and pitching those solutions confidently to customers
• Experience in a SaaS or e-commerce environment, with exposure to external customers and merchant interactions
• Strong stakeholder management skills, with the ability to work effectively across internal teams and with customers at varying levels of seniority, including examples of using AI in demos or pitches

Grow your way

At Mollie, growth is personal. We believe everyone should have the chance to develop their skills, explore new challenges and shape their career on their own terms.

You'll get regular feedback and performance reviews to support your development, with fair and transparent salary reviews along the way. Many Mollies move into new roles or take on new projects to stretch themselves, and we actively hire from within to help you take the next step.

No matter if you're aiming for promotion, exploring a different career path or building new skills, you'll be supported with the tools, trust and opportunities to grow your way.

AI at Mollie

We believe in Always Be Shipping, and AI brings that philosophy to life across every team, every role, every day.

AI is core to how we build. It helps us move faster, simplify work and make smarter decisions, creating real impact for the businesses we serve. We're looking for people who are excited to use AI to shape the future of finance with us.
