Join to apply for the Software Engineer (Fintech Startup) role at ambi. careers

(We are supporting our client, Paynest, in their search for a Software Engineer in Lisbon. Check it out!)

As a Software Engineer on the Client Solutions team at Paynest, you’ll own the critical layer between our platform and our clients. You’ll work across onboarding, client setup, integration support, and product feedback—ensuring customers experience a seamless rollout and rapid value from Day 1.

This isn’t just a support role. You’ll act as a technical partner to our Customer Success and Product teams—building trust with clients while shaping our roadmap with real user insights.

Why This Role Matters

We’re scaling AI-powered expense management for
- sized companies. The difference between a successful rollout and a churned client often comes down to details: proper implementation, strong onboarding, and fast feedback loops. That’s where you come in—closing the gap between engineering and user success.

What You’ll Do

• Guide new clients through onboarding, integration setup, and technical activation.
• Serve as the first technical point of contact for
  - facing questions or light issues.
• Capture and relay product feedback, friction points, and feature requests to the Product team.
• Collaborate with Customer Success and Account Management to ensure client satisfaction.
• Contribute to technical documentation, onboarding flows, and internal tooling.
  
  
  

You Are

• Technically sharp, with experience building or supporting B2B Saa
  S products (1–3 years).
• Highly empathetic and
  - oriented—you think in terms of solutions, not tickets.
• Comfortable in both async and live client communication (calls, Loom, Slack, Notion, etc).
• Process-driven and organized—you don’t let details slip through.
• Ready to grow into a hybrid role (Solutions Engineering, Customer Success Engineering, or Product).
  
  
  

Nice to Have

• Experience with API integrations, light scripting, and/or tools like Postman, Segment, Intercom.
• Exposure to fintech, expense management, payroll, or HR tools.
• Familiarity with debugging logs, frontend inspection, and internal tooling systems.
