Senior Pre-Sales Solutions Engineer

Commercial | EMEA | French Speaking

At Klaviyo, we value the unique backgrounds, experiences and perspectives each Klaviyo brings to our workplace every day. We believe everyone deserves a fair shot at success and appreciate the experiences each person brings beyond the traditional job requirements. If you're a close but not exact match with the description, we hope you'll still consider applying.

About the Opportunity

Solutions Engineers at Klaviyo are technical sellers at the heart of our revenue motion. We don't just demo software. We work as trusted advisors, helping fast-growing commercial businesses understand how Klaviyo can solve their real challenges, and then we prove it.

We're looking for a Senior Pre-Sales Solutions Engineer to join our EMEA Commercial team, covering the Entrepreneur and SMB segment. This is a role for someone who can move quickly through a sales cycle, run sharp discovery, design practical solutions, and deliver demos that actually land. You'll be comfortable talking to both developers and marketers, and you know how to adapt on the fly.

You'll work closely with Account Executives across the French-speaking market and wider EMEA region, owning the technical side of deals from first call through to close. You bring structure and momentum to the sales cycle without slowing it down.

What We Do as Solutions Engineers

We're technical sellers who drive revenue by winning Commercial deals. Our job is to own the technical win. That means building champions, demonstrating clear value, and making sure prospects choose Klaviyo.

We work directly with customers to architect solutions that integrate into their existing tech stacks, taking a consultative approach that builds confidence and secures buy-in from technical and business stakeholders alike.

Our team builds beyond the day-to-day too. Recent projects include AI-powered demo data generators, a Chrome extension for troubleshooting API calls, web SDK injectors, and templatised mobile apps to showcase our SDK capabilities. If you're someone who builds things to solve problems, you'll fit right in.

How You'll Make a Difference

Own the Technical Win

• Partner with Account Executives to lead the technical side of Commercial opportunities from qualification through to close.


• Run focused technical discovery to understand a prospect's goals, current stack, data flows, and constraints.


• Design solution architectures that make the most of Klaviyo's platform, APIs, and integrations to meet customer needs and best practices.


• Deliver tailored demos and presentations to both business and technical audiences, clearly connecting capabilities to real customer outcomes.


• Scope and lead proofs of concept where needed, defining success criteria and keeping things on track.


• Handle objections confidently, navigate competitive situations, and bring clear strategic thinking to deal with conversations.

Be a Trusted Advisor

• Act as a go-to resource for prospects on topics like data strategy, integrations, implementation approach, and long-term scalability.


• Bring subject matter expertise across marketing technology, eCommerce, CDPs, and customer data.


• Collaborate with Product, Engineering, and Support on RFPs, security reviews, and deeper technical evaluations.


• Stay close to the competitive landscape and bring that intelligence into deals in a way that's useful, not just informational.

Build and Contribute

• Contribute to repeatable assets like demo narratives, reference architectures, playbooks, and templates that help the broader team move faster.


• Use AI tools and automation to scale your own impact and improve how you work.


• Provide clear feedback loops to Product and GTM teams on feature gaps, market trends, and what SMB customers are actually asking for.


• Support partner and channel teams where relevant, helping them position and implement Klaviyo effectively for commercial customers.

Who You Are

Required

• Fluent in French and English, written and spoken.


• 3+ years of experience in a pre-sales, solutions engineering, or solutions architecture role at a B2B SaaS company.


• Solid understanding of web technologies, APIs, and data integrations including REST APIs, webhooks, and ecommerce or marketing platforms.


• Comfortable engaging with both technical stakeholders (developers, architects) and business stakeholders (marketing, operations, leadership).


• Strong customer-facing communication skills, with the ability to make complex concepts feel simple and relevant.


• Able to run live product demos and adjust in real time based on the conversation.


• Experience working with commercial customers, with an appreciation for their pace, constraints, and how to design practical solutions that fit.


• A bias toward action and solid problem-solving instincts in fast-moving sales cycles.

Nice to Have

• Hands-on experience with JavaScript, Python, or SQL for light technical validation, data exploration, or integration work.


• Background in marketing technology, CDPs, or customer engagement platforms.


• Familiarity with AI-assisted development tools (e.g. Claude Code, Cursor) and how to use them to move faster.


• Experience with ecommerce technology stacks such as Shopify, Magento, or custom storefronts.


• Experience working with partners or consultancies that serve SMB customers.

What Sets You Apart

• You've used AI to genuinely scale your effectiveness, whether that's through automation, research, demo prep, or light development.


• You roll up your sleeves and become the expert on whatever you need to know.


• You bring competitive intelligence into deals without it feeling like a script.


• You contribute to the team through the assets, playbooks, and feedback you leave behind.


• You thrive in a fast-moving environment and don't need everything mapped out to get started.

How We'll Measure Success

• Technical win rate and contribution to overall win rate in the Commercial segment.


• Quality and consistency of solution designs and handoffs to implementation and Customer Success teams.


• Impact on repeatable assets, team enablement, and process improvements for the broader go-to-market team.


• Feedback quality delivered back to Product and GTM on segment-specific needs.
