Founding Solutions Engineer

Scalar • San Francisco, CA

15h • Onsite

About The Position

Scalar is seeking its first Solutions Engineer to join the founding sales team. This role is crucial for scaling the company's founder-led sales motion by taking ownership of the technical aspects of the sales process. You will work closely with the CEO, learning the existing sales strategy and then building out the technical components, including demos, proofs of concept, migrations, and customer onboarding. This is a unique opportunity to shape how a company sells, build repeatable processes, and directly impact customer success. The buyers are engineers, and the product is the proof. You will be responsible for demonstrating Scalar's capabilities by showcasing live demos, generating SDKs, and setting up MCP servers against prospect APIs. This is a deeply technical role, requiring hands-on coding, a strong understanding of APIs (especially OpenAPI), and the ability to build and fix issues within the product itself. You will also be involved in onboarding new customers and providing technical feedback to the product team. As the company grows, you will help set the technical bar for future hires in this role.

Requirements

• Experience in customer-facing technical roles such as solutions engineering, sales engineering, forward-deployed engineering, developer relations, or consulting.
• Ability to hold your own in discussions with skeptical staff engineers.
• Proficiency in writing code, particularly TypeScript, with the ability to build a working integration live on a call.
• Deep understanding of APIs, including OpenAPI, JSON Schema, authentication flows, and SDK ergonomics.
• Ability to take a deal from the first technical call to signed and successfully onboarded without a pre-existing process.
• Willingness to be honest about limitations and collaborate to find the right answer.
• High level of kindness and collaborative spirit.

Nice To Haves

• Experience at a developer-tools or API company, especially selling to engineering teams.
• Hands-on experience with MCP, agents, or LLM-powered developer tooling.
• Experience with Vue 3 or comfort ramping into it quickly.
• Experience as the first or second Go-to-Market (GTM) technical hire.
• Experience running technical evaluations against enterprise requirements (self-hosting, SSO/SAML, air-gapped deployments, procurement security reviews).
• An in-house-first instinct (building own clients and tooling).
• Open-source contributions.

Responsibilities

• Conduct live demos and hands-on Proofs of Concept (POCs) against prospect's real APIs.
• Scope technical calls, address architecture questions, and handle security and compliance reviews.
• Manage documentation migrations from other platforms (Redocly, Mintlify, Stoplight, ReadMe, homegrown) including cleaning up OpenAPI documents and rebuilding content.
• Demonstrate SDK generation across multiple languages (TypeScript, Python, Go, PHP, Java, Ruby) and troubleshoot spec issues.
• Set up and demonstrate Agent Scalar (MCP servers) against prospect APIs.
• Collaborate with the CEO to formalize the sales motion, including qualification criteria, demo environments, and POC scoping.
• Build sample apps, custom themes, integration glue, and reproduction cases, and contribute fixes to Scalar's own repositories.
• Own the first 90 days of a new customer's onboarding and serve as the technical escalation point.
• Provide product feedback with evidence, including reproductions and potential patches.
• Help set the technical bar for future Solutions Engineers and train new team members.

Benefits

• Flexible, unlimited time off.
• Meaningful early equity.
• Base salary plus variable compensation tied to team and company targets.
• Opportunity to build and shape a sales process.
