Klaviyo has a unique take on the Solution Architect role. While most companies hire SAs to give demos, fill out questionnaires, and explain complicated setups, that makes us yawn. We built a product that anyone can use (just ask our more than 150,000 customers) and we have smart sales reps and customer success colleagues who are true product experts.
So what do we do? We work directly with a small percentage of prospective and existing customers, alongside our sales & customer success teams, as customer-facing engineers to accelerate complex deals and customer value, and technically enable strategic growth. We use these engagements as an opportunity to learn, prototype, and ship meaningful improvements to the Klaviyo experience. We look for interesting problems and aim for solutions that are extensible and reusable (e.g. see our publication Solutions @ Klaviyo ).
When a solution calls for it, we like writing code to solve problems. For example, we've built Chrome plugins, custom functions for importing data via API into Google Sheets, and demo environments that continuously receive data in real-time. In short, we are a team of entrepreneurial builders that believes simple things should be simple and complex things should be possible.
If you get energized by solving real-world customer problems, prototyping solutions, and communicating technical concepts - all within the context of actual customer engagements - this could be for you. What you'll get in return is the opportunity to be part of an extremely high-performing, strategically-important team that works at the exciting intersection of engineering, sales, and customer success.
As our Solution Architect you will work specifically with our post-sales, customer-facing teams: Onboarding/Implementation, Customer Success, & Partner Success. You'll work, alongside a paired strategic counterpart, directly with a subset of existing customers and partners to help them design and develop solutions to enable specific business-need-driven use cases and projects.
How You'll Make a Difference:

• Become a complete expert in the Klaviyo app, from understanding the data pipelines and code base of our integrations to understanding technical tradeoffs between various implementation approaches.
• Serve as technical advisor for enterprise customers, translating business goals into technical solutions that align with customer objectives and industry best practices.
• Provide strategic technical guidance to optimize customers' current solutions and setup and partner with Customer Success Managers (CSMs) to foster strong customer relationships and drive product adoption and expansion.
• Take full ownership of technical deliverables within project milestones and proactively collaborating with project team members to ensure on-time, high-quality outcomes that align with the overall implementation plan.
• Approach use cases with a highly analytical mindset-solving for the customer first, then creating repeatable solutions or collaborating with R&D to drive long-term improvements to the Klaviyo product and customer experience.
• Be the go-to internal technical resource, educating team members as well as customers/partners to provide a consistently positive Klaviyo experience.
• Quantify & build business cases for R&D based on evidence from customer account usage, in order to help guide product roadmap planning for our enterprise customer base.
• Act with urgency and precision to give users best in class support in troubleshooting issues as they arise.

Who You Are:

• 2+ years of experience working in technical or solution consulting with proven expertise in delivering large, enterprise-level solutioning and working in projects with multiple stakeholders across diverse teams and departments.
• An excellent communicator with polished written and verbal skills, with the ability to drive internal and external communication, ensuring clarity, consistency, and accountability throughout the project duration.
• Demonstrated executive presence and the ability to articulate solution tradeoffs, persuading and gaining buy-in from diverse technical and non-technical stakeholders across all organizational levels. This includes effectively communicating the impact of recommendations and guiding their successful implementation.
• A proactive and resourceful problem-solver who takes ownership and drives solutions forward autonomously.
• Experience with web development languages (e.g. HTML, CSS, Javascript) and REST APIs.
• Applied experience with a web app development framework (e.g. React, Node, Angular, Vue, etc.) and/or with a general-purpose programming language (e.g. Python, Ruby, PHP, etc.).
• Proven ability to learn new programming languages and technical concepts with minimal guidance.
• Collaborates with a positive attitude, eagerness to learn, and thrives in a quickly changing environment.
• Knowledge of eCommerce, omnichannel engagement, CDP and B2C CRM is a strong plus.
