What it’s like to work at Topsort

At Topsort, we communicate openly and move fast. We say things as they are, challenge each other early, and embrace feedback with curiosity—it’s how we build better, faster. Every experiment has a purpose, and every outcome helps us make the next decision smarter. There’s no single formula for success here; we find what works, improve it, and scale it.

We’re collaborative internally and competitive externally—never the other way around. The pace is quick, sometimes a 100-mph kind of fast, and that’s what keeps it exciting. We act with intent, lift each other up, and turn bold ideas into real results. No endless meetings here—if it can be done today, it gets done today.

About the Role:

We are looking for a hands-on and client-facing Sales Engineer to join our team. In this role, you will play a pivotal part in translating real-world business needs into scalable and technically sound solutions. You will work closely with Sales, Product, and Engineering teams to support pre-sales conversations and lead technical implementations.

This is a highly technical role with direct customer exposure. As a Sales Engineer, you will act as the bridge between customers and our engineering teams, ensuring that technical capabilities are clearly understood, correctly implemented, and aligned with customer needs.

You will:

• Partner with Sales on Technical Deals: Support technically complex sales cycles, confidently presenting and defending our architecture, APIs, SLAs, and integration capabilities with highly technical customer teams.

• Own Technical Discovery & Demos: Lead technical discovery sessions, product demos, and proof-of-concepts. Maintain and improve demo sandboxes, including building automation to support customer use cases.

• Design & Deliver Integration Solutions: Translate customer needs into concrete technical solutions covering APIs, data flows, authentication, and implementation plans.

• Lead Integrations End-to-End: Own customer integrations as short-lived technical projects, from scoping to delivery. You will be expected to push code as part of this work.

• Handle Technical Discussions: Answer deep technical questions from customers around reliability, performance, failure scenarios, and system constraints.

• Collaborate Across Teams: Work closely with Product and Engineering to surface integration challenges and customer-driven improvements.

• Bridge Tech & Customer: Communicate complex technical concepts clearly to both technical and non-technical audiences.

What We Think You Need to Be Successful

We’re open to candidates who don’t check every box but show strong potential.

Core Requirements & Experience

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field.

• 2+ years of experience in Sales Engineering, Solutions Engineering, Integrations, or a similar engineering role with customer exposure.

• Strong software engineering fundamentals, including the ability to write, read, and push production-quality code.

• Experience working with RESTful APIs, data formats (JSON, XML), authentication mechanisms (OAuth), and system integrations.

• Comfort discussing architecture, performance trade-offs, SLAs, and failure scenarios with technical audiences.

• Experience managing integrations as projects, including coordinating timelines, stakeholders, and technical scope.

• Strong communication skills, active listening, and confidence leading technical conversations with customers.

• Ability to manage multiple parallel integrations and adapt to changing requirements in a fast-paced environment.

*This is an engineering role: Candidates will go through coding and architecture interviews and are expected to push code on the job.

Bonus Points

• Experience in B2B SaaS, ad-tech, martech, or data platforms.

• Familiarity with retail, marketplaces, or media monetization.

• Fluency in additional languages beyond English.

What We Value

At Topsort, we seek professionals who embody the following qualities to drive our mission forward:
