Senior Pre-Sales Solutions Engineer - Enterprise

At Klaviyo, we value the unique backgrounds, experiences and perspectives each Klaviyo (we call ourselves Klaviyos) brings to our workplace each and 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

At Klaviyo, the Sales team prides itself on being made up of marketing and product experts. We’re looking for a Senior Solutions Engineer who brings deep technical mastery, strategic thinking, and the ability to own the most complex, high-stakes Enterprise deals. This is a high-impact individual contributor role for someone who thrives in ambiguity, rolls up their sleeves to master our product at a molecular level, and uses AI and automation to punch above their weight.

As a Senior SE, you’ll be a trusted advisor to both customers and our sales organization — leading technical strategy in 6–7 figure deals, owning solution design, and setting the standard for Solutions Engineering excellence through your work.

What We Do as Solutions Engineers

• We’re technical sellers who drive revenue by winning complex Enterprise deals.
• Our job is to own the technical win — building champions, proving value, and ensuring prospects choose Klaviyo over the competition.
• We work directly with customers to architect solutions that integrate seamlessly into their tech stacks, taking a consultant-first approach that builds confidence and secures technical buy-in.
• Beyond closing deals, we use customer engagements as opportunities to prototype and ship improvements to Klaviyo.

If you’re a creator excited by winning high-stakes deals, prototyping technical solutions, and driving strategic revenue outcomes, this could be the role for you.

How You’ll Make a Difference

• Lead the Technical Win in High-Stakes, Complex Deals
• Own technical strategy for the most complex Enterprise opportunities, navigating multi-layered stakeholder environments, competitive pressures, and sophisticated buying processes with minimal oversight.
• Drive advanced technical discovery, uncovering nuanced pain points and proactively identifying differentiation opportunities.
• Host technical workshops that align solutions to business outcomes, demonstrating executive presence and strategic communication.
• Architect and execute Proof of Value plans that secure technical selection over competitors.
• Partner closely with AEs on deal strategy, bringing competitive intelligence and industry expertise to influence outcomes.

Bring Subject Matter Expertise and Industry Leadership

• Serve as a domain expert in marketing technology, CDPs, AI-driven personalization, analytics, and eCommerce.
• Act as a go-to resource for competitive and industry landscape questions.
• Build strong relationships with R&D, collaborating to drive positive outcomes and influence Klaviyo’s roadmap.
• Contribute high-impact content to the SE Learning Library and mentor peers through example.

Operate with Deep Technical Mastery and Innovation

• Become an expert across Klaviyo’s platform, from data pipelines and integrations to technical trade-offs between implementations.
• Develop broad, advanced familiarity with web development, APIs, cloud computing, and modern software development practices.
• Confidently coach experienced engineers on complex solution design.
• Leverage AI tools and automation to scale impact and improve customer outcomes.
• Prototype solutions and build proof-of-concepts that clearly demonstrate Klaviyo’s differentiation.

Who You Are

Required

• 5+ years of experience in Solutions Engineering or Pre-Sales, with 3+ years leading technical strategy on high-complexity Enterprise deals (6–7 figures) with minimal oversight.
• Familiarity with AI-assisted development tools (e.g. Codex, Claude Code) and emerging patterns such as MCP.
• Strong domain knowledge in marketing automation, CDPs, eCommerce systems, analytics, or data engineering.
• Advanced discovery and requirements-gathering skills across multi-layered stakeholder environments.
• Executive presence with exceptional communication skills, from executive-level conversations to deep technical discussions.
• Proven ability to manage objections, handle challenging conversations, and deliver strategic insights.

What Sets You Apart

• You’ve used AI to scale your effectiveness through automation, research, solution design, or development.
• You bring deep competitive intelligence and understand the landscape intimately.
• You build strong R&D relationships and drive outcomes through influence rather than authority.
• You roll up your sleeves, dig in, and become the expert.
• You elevate team performance through example and enablement.
• You thrive in ambiguity and fast-moving environments.
