Customer Success Engineer - Team lead

Grow with us

Upsales was founded in 2003, grew without a single outside investor, and has been profitable ever since. No VC pressure. No compromises. Just a product customers keep paying for.

We build the leading CRM and AI platform for B2B sales, and we're now in our highest growth phase in years, one of the very few SaaS companies growing profitably while staying genuinely ahead on AI.

If you want real autonomy, colleagues who push you, and work that moves the needle from day one, you'll fit right in.

AI first mindset

We’re not looking for someone who simply uses AI. We want someone who weaponizes it. You treat tools like Claude, ChatGPT, and other AI copilots as force multipliers, allowing you to deliver at a level and speed others can’t match. For you, AI isn’t an add\-on, it’s the default operating system for how you think, work, and lead. You’re relentlessly curious about new capabilities, and you push the limits of what’s possible, turning AI into a competitive advantage for yourself, Upsales, and our customers. This is a role for someone with real ambition: someone who wants to set a new standard for efficiency, precision, and impact in the age of AI.

About the Role

This is a role for someone who thrives at the intersection of technical depth and customer obsession. As Customer Success Engineer – Team Lead, you'll take ownership of how our customers experience, adopt, and succeed with the Upsales platform — not just by solving problems, but by building the systems, processes, and team culture that make great support scalable and proactive.

You'll lead a small CS team while staying hands\-on yourself — troubleshooting technical issues, guiding customers toward better solutions, and collaborating closely with Product and Engineering to continuously improve the platform and the customer journey.

What You'll Do

• Handle and resolve complex technical support cases, and lead the team in doing the same with consistency and quality


• Troubleshoot across system logic, data flows, integrations, and APIs


• Build scalable processes, documentation, and self\-service resources


• Work proactively with monitoring and alerting to identify and address issues before they escalate


• Collect and synthesize customer feedback, insights, and patterns to inform product decisions


• Collaborate with Product and Engineering to improve the platform based on real customer needs


• Lead and develop the CS team — building a culture of ownership, curiosity, and genuine care for customer outcomes


• Drive the adoption and development of AI tools within the team — identifying where automation and AI can improve efficiency, response quality, and proactive support, and helping the team build new ways of working around them

• Technical background in systems engineering, computer science, or similar


• Experience in technical support or customer success engineering in a SaaS environment


• Proven experience leading a team


• A systems thinker who builds processes, not just fixes problems


• Strong analytical skills and comfortable working with data


• Genuinely excited about AI and how it can transform customer success


• Experience with SQL, APIs, or JavaScript is a plus


• Fluent in both Swedish and English
