At Klaviyo, the Sales team prides themselves on being marketing and product experts. While most companies hire pre sales Solutions Engineer to just give demos, fill out questionnaires, and only explain setups, that makes us yawn. As a pre sales Solution Engineer for our Enterprise Sales team, you will be responsible for facilitating long term, deep relationships with the prospects to help drive our market-leading position in the owned marketing space.

So what do we do as Solution Engineers? We work directly with our prospective and existing customers to build technical champions, and help envision how Klaviyo could be used and integrated within our prospects’ and customers' tech stacks. We dive deep, take a consultant-first mindset, and develop solutions that ensure long term success for our customers. 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.

A few things our team has recently built as part of our engagements include:

• Write integration specifications for customers hosting their eCommerce stores on non-standard platforms, ensuring seamless data flow while maintaining platform integrity
• Modified the Magento extension codebase to accommodate specialized data sync requirements, demonstrating our ability to adapt core integrations
• Developed a new integration for Demandware from scratch, showcasing our capability to expand Klaviyo’s ecosystem of partners
• Built Klaviyo's first ever public chrome extension, which allows anyone (marketer or developer) to troubleshoot and audit their front end API calls being sent to Klaviyo more easily.

If you’re a creator that gets excited by driving technical success and prototyping new solutions - all within the context of influencing direct strategic sales - 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 engagement.

How You’ll Make a Difference:

• Spearhead the technical and solution pre sales campaign to prospective Klaviyo Mid Market and Enterprise clients to help Klaviyo hit its revenue targets, including
• Technical discovery around current customers architectures, understanding their business and technical challenges and opportunities
• Host technical workshops where you’ll be working with developers and business teams to align technical solutions to overall business outcomes
• Architect and execute Proof of Value plans to achieve technical selection over the competition
• You will become a complete expert in the Klaviyo experience, from understanding the data pipelines and code base of our integrations to understanding technical tradeoffs between different implementations

• Be the go-to internal technical and subject matter expert resource, educating sales team members as well as prospects/customers to provide a consistently positive Klaviyo experience.

Klaviyo in APAC:

We are starting small but have big plans for Klaviyo in APAC. Our Sydney team began to take shape throughout 2022 and has now built out our go to market teams in sales, customer success, partnerships, marketing, recruiting and product support. As the team grows we will see a continued expansion of Klaviyo’s customer base and the building of a fantastic working culture in line with what we see elsewhere in Klaviyo but with its own local identity within our Sydney based team. This is your unique opportunity to join us at a very early stage and help to shape our future Klaviyo in APAC.

One of our values as a company is ‘always learning’ and you can feel that in APAC. People are looking to grow and develop and Klaviyo provides a great platform to do so. As we are still relatively early in our journey in APAC this means there is a lot of headroom to grow and develop within your role - we are looking for the leaders of the future. At Klaviyo generally managers are often promoted up into their roles and people are regularly being promoted or moving into new functional areas - it really is an education through experience here.
