Your impact
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
bring Mollie's API capabilities to life in a compelling and relevant way
ensuring every deal is grounded in a thorough understanding of the customer's environment
rather than standard plugin implementations
opportunities within existing accounts
the broader sales and commercial teams
transition that sets customers up for success
What you'll bring
background in engineering (mechanical, software, or similar)
integrations
concepts clearly for both technical and non-technical stakeholders
solutions and pitching those solutions confidently to customers
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.

WHAT YOU’LL NEED * Proven experience in technical consulting, technical customer success, solution engineering, or a similar customer-facing technical role. * Hands-on experience with DevOps practices and tooling, including CI/CD systems, source control platforms, cloud infrastructure, and containerized environments. * Proficiency with software development tools, gained through practical work in software development, QA, system administration, or release automation. * A practical understanding or hands-on exposure to AI/LLM applications within software development workflows. * Professional fluency in English, with strong verbal and written communication skills for remote and in-person presentations, product demos, and roadmap discussions. * The ability to travel internationally as required by the role. WHAT SUCCESS LOOKS LIKE Success in this role means earning your customers' trust through sound architectural guidance and reliable support.
