Klaviyo is seeking a Senior Pre-Sales Solutions Engineer to join the EMEA Commercial team, covering the Entrepreneur and SMB segment. This role sits at the heart of the revenue motion—you'll act as a technical seller and trusted advisor, helping fast-growing commercial businesses understand how Klaviyo's platform solves their real challenges.
You will own the technical side of deals from first call through close, working closely with Account Executives across the German-speaking market and wider EMEA region. Your responsibilities include running focused technical discovery to understand prospects' goals, current tech stacks, data flows, and constraints; designing solution architectures that leverage Klaviyo's platform, APIs, and integrations; delivering tailored demos and presentations to both business and technical audiences; scoping and leading proofs of concept; and handling objections confidently in competitive situations.
Beyond deal work, you'll act as a go-to resource for prospects on data strategy, integrations, implementation approach, and scalability. You'll bring subject matter expertise in marketing technology, eCommerce, CDPs, and customer data. You'll collaborate with Product, Engineering, and Support on RFPs, security reviews, and technical evaluations, and stay close to the competitive landscape to bring useful intelligence into deals.
The team also builds beyond day-to-day selling. Recent projects include AI-powered demo data generators, Chrome extensions for troubleshooting API calls, web SDK injectors, and templated mobile apps to showcase SDK capabilities. You'll contribute to repeatable assets like demo narratives, reference architectures, playbooks, and templates that help the broader team move faster. You'll use AI tools and automation to scale your own impact, provide feedback loops to Product and GTM teams on feature gaps and market trends, and support partner and channel teams where relevant.
Success is measured by technical win rate and contribution to overall Commercial segment win rate, quality and consistency of solution designs and handoffs, impact on repeatable assets and team enablement, and feedback quality delivered back to Product and GTM on segment-specific needs.
Klaviyo empowers creators to own their destiny by making first-party data accessible and actionable. The company is building technology to nurture personalized experiences in eCommerce and beyond. The role may require up to 10% travel for new hire onboarding, client or partner work, team meetings, and industry events.

- Able to run live product demos and adjust in real time based on conversation
- Experience working with commercial customers, with appreciation for their pace, constraints, and how to design practical solutions that fit
